Abstract (en)

[origin: WO9923940A1] A non-invasive methodology and instrumentation for the detection and localization of abnormal blood flow in a vessel of a patient, are described. An array of sensors (131) is positioned on an area of a patient's body above a volume in which blood flow may be abnormal. Signals detected by the sensor array (13) are processed to display an image which may indicate the presence or absence of abnormal blood flow.
