Intended Use

The Alturion Series Diagnostic Ultrasound System is indicated for diagnostic ultrasound imaging and fluid flow analysis of the human body in the following indications for use: Abdominal, Cardiac Adult, Cardiac Other (Fetal), Cardiac Pediatric, Cerebral Vascular, Cephalic (Adult), Cephalic (Neonatal), Fetal/Obstetric, Gynecological, Intraoperative (Vascular), Intraoperative (Cardiac), Musculoskeletal (Conventional), Musculoskeletal (Superficial), Ophthalmic, Other: Urology, Pediatric, Peripheral Vessel, Small Organ (Breast, Thyroid, Testicle), Transesophageal (Cardiac), Transrectal, Transvaginal, Lung.

Technology

The device is a software-controlled diagnostic ultrasound system consisting of a system console and transducers. It supports multiple imaging modes including B-mode, M-mode, Doppler, 3D/4D imaging, and harmonic imaging. The Alturion Series includes an AI Auto Measure Abdomen feature to automate measurements in abdominal exams. The system uses common software architecture from the predicate Affiniti Series with improved acoustic capabilities.

Performance

Non-clinical verification testing includes IEC and ISO standards for medical electrical safety, software lifecycle, ultrasound field characterization, biocompatibility, and risk management. Performance validation of the AI Auto Measure Abdomen feature was conducted using ultrasound images from 150 subjects, comparing AI measurements to manual expert measurements, showing strong concordance within acceptance criteria.
