Kosmos Anatomical Object Labeling and View Identification Pivotal Study

EchoNous Inc.32 enrolled

Overview

This is a multi-site, multi-group study that obtained two sets of ultrasound scans from all enrolled participants. Participants underwent limited ultrasound scanning by both cardiac sonographers and abdominal sonographers. Algorithm's performance on the view identification task and the object labeling task is computed.

Kosmos Anatomical Object Labeling and View Identification AlgorithmsDEVICE

Participants underwent limited ultrasound scanning by both cardiac sonographers and abdominal sonographers. Algorithm's performance on the view identification task and the object labeling task is compared to majority opinion of 5 radiologists.

Outcomes

Primary Outcomes

False discovery rate of the anatomical object labeling function on expert-obtained images

The objective of this study is to compare the average frame-level disagreement of object labeling by majority opinion of five expert reviewers. The frame-level disagreement is defined as False Discovery Rate as in (1) FDR = 1-Precision=FP/(FP+TP) (1) Where TP≡True Positive and FP≡False Positive. A True Positive is counted when the majority opinion of five expert reviewers agrees with the location of predicted labels in the image. A False Positive counted when majority opinion of five expert reviewers disagrees with the location of one or more predicted labels. False Discovery Rate (FDR) is measured for a particular image frame between predicted objects and the majority opinion of five reviewers. The frame-level FDR threshold for this prospective study is 20%. Therefore, for a successful outcome the frame-level FDR must be less than 20%.
