Evaluation of the LVivo Image Quality Scoring (IQS)

The study includes two parts: Part 1: * 100 examinations of patient referred for echo evaluation, containing clips that were acquired from the 4CH apical view were collected retrospectively. Each study includes 10 clips that represent typical user scanning errors * Offline evaluation of the system (by batch processing) shall be performed by comparing the system output to preliminary quality tagging by experienced sonographers Part 2: * Live scans of apical 4CH clips of patients with indication for POCUS examination will be performed by POC physicians * LVivo IQS shall be used (on Lumify) during the scan for patients that meet inclusion criteria until 50 exams will be collected. 3 sec of each scan shall be saved, and Image quality score (IQS) shall be documented * Saved scans shall be reviewed by an expert physician to determine whether they are clinically interpretable
