CARDIOVASCULAR SOUND ANALYSIS METHOD AND SYSTEM Russian patent published in 2009 - IPC A61B7/00 

FIELD: medicine.

SUBSTANCE: method and system analyse sounds generated, at least, in part of human cardiovascular system. N of converters, where N is an integer, are fixed on body surface within breast region. The i-th converter is fixed in position x_i and generates initial signal P(x_i, t), expressing compression waves in position x_i, where i=1...N. Signals P (x_i, t) are processed to shape filtered signals, wherein at least one component of signals P(x_i, t), not generated by cardiovascular sounds, is removed. The filtered signals can be used for imaging of, at least, part of cardiovascular system.

EFFECT: higher accuracy of moving image analysis.
