Fetal Heart Ultrasound Suspicious Radiographic Finding Identification - Reader Study

April 26, 2024 updated by: BrightHeart
Clinical performance of the device will be evaluated in a fully-crossed, multiple-reader multiple-case (MRMC) study. This study will be used to determine the impact of the device on reader performance in identifying suspicious radiographic findings in fetal heart ultrasound video clips recorded during 2nd trimester anatomic ultrasound examinations conducted during the second trimester of the pregnancy.
