1 Introduction

This document is the user guide for ViewPoint EchoPilot , a Software as a Medical Device licensed by GE Healthcare. It is recommended that you read this instruction manual carefully before use.

ViewPoint EchoPilot is a clinical decision support tool that analyzes echocardiogram images in order to generate a series of AI derived measurements. Fully automated, functional reporting with disease indications are also provided, in line with ASE & ESC guidelines.

Echo images are sent to the ViewPoint EchoPilot platform where they are processed, analyzed and measured. Results that meet the confidence threshold for both image quality and measurement accuracy are passed through to a report for review by the clinical users. Report text is also generated and presented with the measurements, providing functional reporting and disease indications.

ViewPoint EchoPilot greatly reduces user time spent creating manual measurements and allows clinical users to prioritize quality image acquisition and clinical time with patients.

Benefits

• No limitation on the number of users or echo scanner connections, with simple per exam pricing.
• ViewPoint EchoPilot processes DICOM image data and produces measurements in ~2 minutes.
• Removes/reduces the need for clinical staff to spend time measuring, increasing efficiency and throughput of patients.
• Eliminates operator variability, providing more accurate and consistent results than humans.
• Custom measurements can be made using the intuitive user interface.
• Image viewer is integrated into the web application and linked to the measurements, which makes reviewing images and measurements a single click.
• Results and measurements can be sent to EHR, PACS, CVIS as discrete measurements (HL7, CSV, DICOM SR, Encapsulated PDF) or stored as a formatted PDF report for review/signature/approval.
• All data is standardized and structured in a single DICOM SR format regardless of the source echo machine.

1.2 Intended Use

This software is used to process acquired transthoracic cardiac ultrasound images, to analyze and make measurements on images in order to provide automated estimation of several cardiac structural and functional parameters, including left/ right atrial and ventricular linear dimensions, volumes, systolic function and diastolic function, measured by B mode, M mode and Doppler (PW, CW, tissue) modalities.  The data produced by this software is intended to be used to support qualified cardiologists, sonographers, or other licensed professional healthcare practitioners for clinical decision-making. The software is indicated for use in adult patients.

1.3 Contraindications and Limitations

Because ViewPoint EchoPilot measurements cover the minimum echocardiographic dataset for a standard adult echocardiogram (by European Society of Cardiovascular Imaging, British Society of Echocardiography and American Society of Echocardiography guidelines), our software is applicable to the vast majority of adult transthoracic echocardiograms.

Our current software aims to automate measurements of cardiac dimensions and left ventricular function and are applicable regardless of normal or disease states. We specifically indicate that our current product will not be reporting measurements associated with intra-cardiac lesions (e.g. tumours, thrombi), nor complex adult congenital heart disease.

Please note the following additional limitations:

• Poor image capture will lead to poor annotations and subsequent measurements. Multiple image quality algorithms are used to filter out images of poor quality.
• Our software complements good patient care and does not exempt the user from the responsibility to provide supervision, clinically review the patient, and make appropriate clinical decisions.
• If no gender is present, female referenced guideline values will be used for conclusions.
• If Body Surface Area (BSA) is not present, indexed values cannot be provided.
• Normal reference values vary with age, sex, and In case of doubt always refer back to the appropriate cardiac society's guidelines.
• During image acquisition, inappropriate use of the echo machine, use of non- cardiac ultrasound probes, use of suboptimal settings (e.g. gain, contrast, depth), or lack of EKG capture may lead to lower accuracy of the software.
• ViewPoint EchoPilot does not identify regions of interest or areas of possible pathology in the images.
• ViewPoint EchoPilot does not differentiate different types of Cardiac Amyloidosis e.g. ATTR, AL etc.
• ViewPoint EchoPilot was externally validated on cardiac images from GE and Philips ultrasound systems. Use of the device on ultrasound systems other than GE and Philips may lead to lower accuracy of the software.

1.4 Clinical Benefits

ViewPoint EchoPilot is an image post-processing analysis software device used for viewing and quantifying cardiovascular ultrasound images in DICOM format. The device is intended to aid diagnostic review and analysis of echocardiographic data, patient record management and reporting.

The primary intended function of ViewPoint EchoPilot is to automatically provide clinically relevant and reproducible quantitative echocardiographic measurements, while reducing echocardiographic analysis time. In doing so, the primary benefit of ViewPoint EchoPilot is to improve clinical echocardiographic workflow, enabling clinicians to generate and edit reports faster, with precision and with full control.

Today, the clinical workflow of a sonographer is as follows:

1. The sonographer performs the echocardiography exam (“echo exam”) to capture the images/videos.
2. The specialist sends the images/videos to a server for picture archiving and communication system (PACS).
3. Another specialist retrieves the images/videos from the PACS and downloads them onto a local workstation to then:
   1. Review the images/videos. Manually determine which view has been captured.
   2. Manually determine the cardiac structures imaged within the captured view.
   3. Manually segment and draw annotations on the region of interest (ROI) in order to perform measurements.
   4. Manually refer to standard reference guidelines to determine if any of the potentially dozens of measurements performed fall within the normal range of values for that patient’s sex or ethnicity.
   5. Manually create a report based upon the conclusions drawn from the measurements.

This process can be prone to human error, and is more importantly time-consuming, placing a rate on the number of exams that can be processed within a given unit of time.

The goal of ViewPoint EchoPilot is to simplify much of this process through machine learning based automation, so that the workflow becomes:

1. The sonographer performs the echo
2. The sonographer sends the images/videos to a PACS
3. ViewPoint EchoPilot retrieves the images/videos from the PACS and processes them, allowing a sonographer to then:
   1. Review the report which has already highlighted measurements that fall outside of normal ranges.
   2. Review the original images/videos, if desired.
   3. Manually adjust any of the automated segmentations and measurements if desired.

1.4.1 Enhanced Echocardiographic Reporting: Balancing Automated Analysis with Manual Review

While the software does not require human intervention to automatically produce a full report, the software provides an interface for a skilled sonographer/ reviewing physician to perform edits/ revise the markup on the echocardiographic image measurement if needed. The markup includes: the cardiac segments captured, measurements of distance, time, area and blood flow, quantitative analysis of cardiac function, and a summary report.

The software allows the sonographer to enter their markup manually. It also provides automated markup and analysis, which the sonographer may choose to accept outright, to accept partially and modify, or to reject and ignore. Machine learning based view classification and border detection form the basis for this automated analysis. Additionally, the software has features for organizing, displaying and comparing to reference guidelines the quantitative data from cardiovascular images acquired from ultrasound scanners.

3 Installation

ViewPoint EchoPilot is available as a cloud service, installed on premises (hard server or suitable VM), or on a high end tablet, laptop or workstation, for direct connected offline use. Workflows are fully configurable, the software can be interfaced and integrated with any combination of echo scanners and PACS/EMR/reporting packages.

ViewPoint EchoPilot comes in two configurations:

3.1 Cloud workflows

Images can be sent to our cloud application directly with DICOM TLS or via the ViewPoint EchoPilot DICOM Router installed on a local server or workstation.

Browser requirements: The ViewPoint EchoPilot client application is specified for use with version 93+ of chromium through Edge, Chrome and Brave. A minimum of 4GB of RAM is recommended.

3.1.1 DICOM send via TLS

The ViewPoint EchoPilot provides a secure interface for securely exchanging data between echocardiography machines and the ViewPoint EchoPilot cloud platform using TLS encryption. Follow the steps below to configure PACS (TLS) integration:

• Navigate to PACS Configuration:
  • Open the ViewPoint EchoPilot and go to Settings → Workflow Integration → PACS Config (TLS).
• Enable PACS Communication:

  Ensure the following toggles are turned on:

  • Enable PACS (TLS)
  • Whitelist Sending AE Title (SCU)
• Whitelist SCU AE Titles:
  • To authorize DICOM communication, enter the SCU AE Title(s) for any connected echocardiography machines. Make sure the corresponding checkboxes are selected to activate each entry.

    

• Save Configuration:
  • Once complete, click Save Changes to apply the new configuration. A confirmation message “Config saved successfully… Close” will appear at the bottom of the page.
• Record PACS Destination Details: Note the SCP (Cloud PACS) details displayed. These must be entered as the DICOM destination on each SCU (Echo machine). The required information includes:
  • EchoPilot Host IP Address or Domain (there are two IP addresses displayed, use either): Example: 18.198.159.253 or 3.75.118.187
  • EchoPilot Port: 11113
  • EchoPilot AE Title: Example: JUM_12527199
• (Optional) Server Certificate:

  If required by your echocardiography machines, download the server certificate and import it to enable secure TLS communication.

3.1.2 DICOM send and receive via DICOM router

The ViewPoint EchoPilot DICOM router is a software solution designed to securely exchange data between echocardiography machines, PACS systems, and the ViewPoint EchoPilot cloud platform. It offers several key features:

• Bi-directional communication: The router can send and receive DICOM data (images, structured reports, PDFs) as well as HL7 messages (electronic health records format) between your local network and the ViewPoint EchoPilot cloud.
• Outbound:
  • Send DICOM images with AI-generated measurements overlaid.
  • Transmit DICOM structured reports (measurements and text data).
  • Forward DICOM PDF reports or HL7 messages to your local PACS or EMR system.
• Inbound:
  • Receive results (reports) from the ViewPoint EchoPilot cloud and forward them to your local network.
• Security:
  • The router provides anonymization and encryption services prior to upload, acting as a single point of exit, allowing multiple echo scanners or PACS servers to securely communicate data bi-directionally with the ViewPoint EchoPilot cloud, which is hosted in AWS.
• Flexibility:
  • Outbound-only mode: For networks with restricted internet access, the router isolates echo machines from the internet while still allowing data exchange with ViewPoint EchoPilot .
  • User-configurable settings: Manage settings directly within the ViewPoint EchoPilot application after initial setup with ViewPoint EchoPilot support.

   

The ViewPoint EchoPilot DICOM router removes the need for a VPN while offering benefits such as monitoring, logging and flexible configurations to fit customer workflows. However, it's important to consider potential PACS incompatibility with MP4 compression as it greatly reduce the file sizes prior to upload. If source DICOM images are required to be exported from ViewPoint EchoPilot in the future, please request that this is disabled on installation (i.e., if the ViewPoint EchoPilot cloud application is your primary image storage). In most cases, source DICOM images have already been sent to a PACS and will not need to be exported from ViewPoint EchoPilot .

3.1.2.1 Requirements

The DICOM router can be installed on a workstation or server on the users network, and must be reachable by all echo machines and PACS servers that will send or receive data.

Minimum specification:

• 4GB RAM, 1 Core CPU.
• Windows 10 or higher (for Linux distributions please contact your ViewPoint EchoPilot representative with your request)
• Static IP address
• Internet facing with open ports:
  • inbound 11113
  • outbound 443
  • plus any ports used to send to onsite PACS/EMR (defined by the PACS manager)
• Remote access by ViewPoint EchoPilot staff is required for specialized configurations, which can be supervised access only

3.1.2.2 Installation

To setup the DICOM router, follow the steps below:

CALL echopilot.exe --app-config --username <username> --password <password>

• The DICOM router software is now running as a DICOM SCP and can be set as a DICOM server destination on echo machines and PACS servers:

6 Performance Summary

The automated analysis generated by ViewPoint EchoPilot will be compared head-to-head against manual analysis (of the same patient data and the same images) generated by trained echocardiography technicians or cardiologists, both in “gold standard” reference echo core labs and “real world” clinical settings. Test datasets are strictly segregated from algorithm training datasets, as they are from completely separate cohorts. Two statistical metrics, Root Mean Square Error (RMSE) and Intraclass Correlation Coefficient (ICC) are used to evaluate the performance of the ViewPoint EchoPilot measurements against expert human measurements.

DICOM images from a wide variety of manufacturers were used to validate the software. DICOM metatag data available in these files contained the following manufacturer and models for the respective versions of our software:

DICOM images used for validation were captured with a variety of convex, linear and phased array probes showing an acquired frequency ranging between 1.4-10 MHz, and a Frames Per Second (FPS) range of 7- 209, with a mean of 31 from the following models, when information was available in the DICOM tags:

6.1 ViewPoint EchoPilot

6.2 Supplementary Cardiac Amyloidosis AI module

The supplementary Cardiac Amyloidosis AI module was developed using a training dataset comprising 4,371 patients and externally validated on an independent pooled dataset of 1,647 patients. The training and external validation datasets were sourced from entirely separate data providers, ensuring no overlap and maintaining full independence between development and evaluation. The external validation cohort included a demographically and geographically diverse population, collected from six clinical sites across the United States and Japan. All echocardiographic studies were retrospectively obtained from routine clinical evaluations and provided in standard DICOM format. Ultrasound data were obtained from GE, Philips, and Siemens systems to train the machine learning-based software device, but the testing data were only obtained from GE and Philips systems.

When tested on a total of 1647 patients, Us2.ca was able to generate a confident prediction for 1434 patients (CA group: 574 patients; Controls group: 860 patients), in which it performed with a sensitivity of 86.9% (95% CI: 84.2%-89.7%) and Specificity of 87.4% (95% CI: 85.2%-89.7%). The overall yield, which refers to the proportion of total tested patients for whom the device was able to generate a confident prediction, is sufficiently high at 87.1%.

Physical security for on-premises solutions is the responsibility of the customer.

7.3 Firmware/Software

The ViewPoint EchoPilot application is hosted on the AWS platform and therefore implements AWS WAFv2 on all our cloud endpoints. Additionally, Crowdstrike Falcon is seamlessly deployed on the ViewPoint EchoPilot system, serving as a robust security solution with advanced anti-virus, anti-malware, and anti-ransomware features, ensuring real-time threat detection and response capabilities.

Software deployed to cloud servers is done by taking a hash of the code and deploying only code that matches the hash. All code is hosted in a private code repository where a complete record of code changes is kept and only authorized users can make changes.

7.4 Privacy and Security

The ViewPoint EchoPilot DICOM router prioritizes data security throughout the communication process. All communication between the router and the ViewPoint EchoPilot cloud is encrypted using the industry-standard 256 AES encryption over HTTPS. Additionally, any data exchanged with the ViewPoint EchoPilot platform itself benefits from encryption with a minimum TLSv1.2 protocol, ensuring your information remains secure at every step.

DICOM TLS is also available to encrypt local traffic on the user network (between the echo scanners and the DICOM router) where required - please contact your ViewPoint EchoPilot representative to enable this feature.

Local hard drives can be encrypted. Updates and antivirus can be deployed in accordance with local IT policies. After testing, certain folders and processes may need to be excluded to optimize performance.

7.5 Logging and alerting

All traffic and changes within our cloud platform is logged. These logs are scanned with compliance rules provided by our cloud provider (AWS). These services include: Control Tower Guard Rails, AWS Guard Duty, AWS Security Hub, Security Hub HIPAA compliance, Security Hub Best Practices. The manufacturer’s operations maintains a 24 hour SLA on investigation and classification of all cloud platform alerts.

7.6 Maintenance of Cybersecurity on devices

The manufacturer constantly monitors and periodically performs both internal and external scans on all devices.

Internal Operating systems and infrastructure patches/upgrades are periodically evaluated, reviewed and tested in our test environment prior to deployment. Any patches to be installed will be scheduled for off-peak hours so as to minimize any business disruptions.

7.10 End of Service data handling

Upon the expiration or termination of your ViewPoint EchoPilot subscription, your account will enter a standard 30-day grace period (or as otherwise specified in your Service Agreement). During this interval, your data remains securely archived but accessible should you choose to renew your services.

Following the conclusion of this grace period, or upon a formal request for immediate removal, GE Healthcare performs a permanent and irreversible disposal of all customer data hosted on our AWS S3 infrastructure. To ensure data integrity and security during this process, we employ the following safety protocols:

Cloud-Based Subscriptions (SaaS) Upon account termination, a 30-day grace period applies, after which data is permanently purged from AWS S3 infrastructure. To ensure secure disposal, GE Healthcare utilizes programmatic deletion and version purging in alignment with NIST 800-88 standards for media sanitization. Immediate removal may be requested in writing; however, once initiated, data is unrecoverable.

On-Premises Deployments For on-premises installations, the purchasing institution maintains exclusive responsibility for data destruction. All retention and disposal activities must be executed according to the customer's internal IT governance and local regulatory requirements.

Warning: Once the disposal process is finalized, data cannot be recovered.
