Output	Patient report, editable image annotations, comparison to international reference guidelines
Output format	DICOM SR, PDF, CSV
Technology
Integration	Integration in standard reading environment (PACS), Integration CIS (Clinical Information System), Integration via AI marketplace or distribution platform, Stand-alone third party application, Stand-alone webbased
Deployment	Locally on dedicated hardware, Locally virtualized (virtual machine, docker), Cloud-based, Hybrid solution
Trigger for analysis	Automatically, right after the image acquisition, On demand, triggered by a user through e.g. a button click, image upload, etc.
Processing time	1 - 10 minutes

Regulatory

Certification
CE	Certified, Class IIb , MDR
FDA	510(k) cleared , Class II
Intended Use Statements
Intended use (according to CE)	Us2.v1 is a software platform that automatically processes, analyses and makes measurements on acquired transthoracic cardiac ultrasound images, producing a full report with measurements of several key cardiac structural and functional parameters. 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. Us2.v1 is indicated for use in adult patients. Us2.v1 has not been validated for the assessment of congenital heart disease, valve disease, pericardial disease, and/or intra- cardiac lesions (e.g. tumours, thrombi).
