DEVICE AND METHOD FOR EXTRACTING PHYSIOLOGICAL INFORMATION

Physiological information is extracted from detected electromagnetic radiation emitted or reflected by a subject (10). A data stream (30) derivable from the electromagnetic radiation is received. The data stream (30) includes a sequence (76; 152) of signal samples (78a, 78b, 78c; 154a, 154b, 154c) i...

Zusammenfassung:	Physiological information is extracted from detected electromagnetic radiation emitted or reflected by a subject (10). A data stream (30) derivable from the electromagnetic radiation is received. The data stream (30) includes a sequence (76; 152) of signal samples (78a, 78b, 78c; 154a, 154b, 154c) indicative of desired subject motion and of disturbing motion, the signal samples representing at least one region of interest (84; 164) and at least one non-indicative motion region (86; 166). The at least one defined region of interest (84; 164) exhibiting an at least partially periodic indicative motion pattern attributable to at least one physiological parameter (56), and a disturbing motion portion. A sequence (158) of motion compensated samples (80; 160a, 160b, 160c) at least partially compensated for undesired overall motion is derived. At least one characteristic signal (90; 112) at least partially indicative of the at least partially periodic indicative motion pattern is derived from the sequence (158) of derived motion compensated samples (80; 160a, 160b, 160c).
