BioScan is a medical device software intended for user-initiated, non-invasive self-measurement of selected physiological parameters by laypersons using remote photoplethysmography (rPPG) via compatible mobile devices equipped with a camera. The device provides outputs for health awareness only and is intended to support personal self-monitoring of physiological parameters without clinical interpretation. It is not intended to provide a diagnosis, to replace medical examinations or professional medical advice, or to be used for clinical decision-making. The information provided may encourage users to consult a qualified healthcare professional if they have health-related concerns. It does not replace measurements obtained using clinically validated medical devices and/or methods used as part of established standards of care and shall not be used as a substitute for such devices and/or methods. The user is not intended to interpret or take clinical action based on the device output without consultation with a qualified healthcare professional.
Features available to users
Measured physiological parameters
Blood pressure (systolic and diastolic), pulse rate (PR), respiratory rate (RR), haemoglobin (Hb), and glycated haemoglobin (HbA1c).Contactless, non-invasive, spot-check measurement.Typically, under 1 minute
Principle of operation
How does it works ?
BioScan MDSW utilises the integrated front-facing camera of a compatible smartphone to capture a continuous video stream of exposed facial skin. The embedded algorithm processes the acquired video frames to extract rPPG signals, detecting subtle variations in skin colour that occur as a result of blood volume changes in superficial blood vessels during the cardiac cycle.
Measurement method
Remote photoplethysmography
Remote photoplethysmography (rPPG) based on analysis of short facial video sequences captured by the integrated front-facing camera. The signal extraction and analysis are supported by embedded artificial intelligence (AI) algorithm, enabling automated, contactless estimation and presentation of physiological parameters from optical data.
