A non-invasive methodology and instrumentation for the detection and localization of abnormal blood flow in a vessel of a patient is described. An array of sensors are 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 are processed to display an image which may indicate the presence or absence of abnormal blood flow.

[ We claim:] [1.]1. A non-invasive, in vivo, method for detecting change in coronary artery stenosis which comprises the steps of:(i) procuring a plurality of heart sound data sets which are indicative of a stenosis in a patient's coronary arterywherein each of said data sets is procured at a different time,(ii) comparing at least two of the data sets to identify selected differences between said sets,wherein a difference identified in said comparing step corresponds to a change in the coronary artery stenosis of the patient.
