EPIQ Series Diagnostic Ultrasound System; Affiniti Series Diagnostic Ultrasound System

Philips' EPIQ and Affiniti Series ultrasound systems, enhanced by the AutoMeasure V3 software, leverage AI-algorithms trained with machine learning to provide semi-automated 2D, Doppler, and M-mode measurements for adult echocardiography, aiming to improve diagnostic efficiency. Non-clinical verification and performance validation studies affirm the system's accuracy and substantial equivalence to prior devices, ensuring its safety and effectiveness for clinical use.

Philips Ultrasound LLC's EPIQ and Affiniti Series Diagnostic Ultrasound Systems are designed for broad diagnostic imaging and fluid flow analysis, covering applications like cardiac, fetal, and musculoskeletal imaging in various clinical settings. A key update is the integration of AutoMeasure V3 software, which provides semi-automated 2D, Doppler, and M-mode measurements specifically for adult echocardiography, powered by an AI-algorithm utilizing machine-learning techniques. Regulatory review concluded that the updated systems, including AutoMeasure V3, are substantially equivalent to prior versions, despite introducing new M-mode measurements, additional detectors, and re-trained existing ones. Comprehensive non-clinical verification and a performance validation study confirmed high agreement between AutoMeasure V3's measurements and standard of care, affirming its continued safety, effectiveness, and suitability for its intended diagnostic use.
