Abstract: A system, particularly a photo-plethysmographic system, determines vital sign information of a subject. A marker includes a marker area such as fluorescent or luminescent pigments, that emits light towards a skin of the subject. Light reflected by the skin is encoded with information about blood in the skin. An attachment layer attaches the marker to the subject. A detector, such as an optical camera, detects radiation reflected from the skin of the subject, and an analysis processor determines the vital sign information, such as heart rate and blood oxygen (SpO2), of the subject from the detected radiation reflected from the skin of the subject.

Abstract: A method of recognizing at least one moving anatomical structure using ultrasound data that operates by receiving ultrasound data (100). The ultrasound data comprises Doppler shift information which provides information descriptive of the velocity of at least one anatomical structure. The ultrasound data is first divided into a series of time frames (102). A classification is then assigned to each of the time frames using the Doppler shift information (104). The at least one anatomical structure is then recognized by using the classification of each time frame (106). This is possible, because different anatomical structures produce different patterns in the Doppler shift information.
