- Effect Size of Human Reader Improvement: Not applicable, as no MRMC study was conducted.
-
Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study:
- Not applicable in the context of a separate "standalone" study for novel algorithm performance. The device itself is software that provides image processing, annotation, analysis, and measurement tools for diagnostic review by a physician. Its performance is inherent to its functionality and how it supports a human user in interpreting specific ultrasound findings. The performance of its new features (Myocardial Work, 4D Auto RVQ/MVQ, Cardiac AutoDoppler, 3rd party DICOM SR Read) is assessed through comparison to existing or predicate functionalities and non-clinical testing.
-
Type of Ground Truth Used:
- Not applicable for a clinical ground truth in the context of a new efficacy study. For the non-clinical software testing, the "ground truth" would be defined by explicit software requirements and expected outputs based on the predicate device's behavior or industry standards. The new features ("Myocardial Work", "4D Auto RVQ/MVQ") are described as building on or being alternative implementations of existing functionalities, implying their performance aligns with the established behavior of those predicate features.
