Embodiment Construction

[0037] The method of the present invention is to process at least one heart sound signal for outputting a more understandable phonocardiogram (hereinafter referred to as PCG), so that one can make a diagnosis conveniently and accurately.

[0038] figure 1 is a schematic diagram illustrating one embodiment of the method according to the invention. The method for processing at least one heart sound signal comprises the steps of:

[0039] - receiving 11 at least one heart sound signal;

[0040] - segmenting 12 said at least one heart sound signal into segments;

[0041] - Identify 13 attribute information of each segment;

[0042] - Annotate 14 each segment with corresponding attribute information; and

[0043] - Output 15 annotated PCG for said segments.

[0044] (1) Receive 11 at least one heart sound signal

[0045] The at least one heart sound signal may include one heart sound signal or multiple heart sound signals from different heart sound sources. The plurality of ...

Abstract

The present invention provides a method of processing at least one heart sound signal, and the method comprises the steps of: receiving (11) said at least one heart sound signal; dividing (12) the heart sound signal into a plurality of segments; identifying (13) each attribute information of the segments; annotating (14) each segment with corresponding attribute information; and outputting (15) an annotated phonocardiogram for the at least one heart sound signal. The invention also provides a processing system for implementing the steps of the method as described above.

Description

technical field [0001] The present invention relates to methods and systems for processing sound signals, in particular to methods and systems for processing heart sound signals. Background technique [0002] Based on different heart sound sources, the heart sound signal detected from the stethoscope can include different types of segments, such as S1 segment caused by the closure of the mitral and tricuspid valves, S2 segment caused by the closure of the aortic and pulmonary valves , the S3 segment caused by rapid ventricular filling during early diastole, the S4 segment caused by atrial contraction that moves blood into the dilated ventricle, the murmur may be caused by blood turbulence. Sometimes, different types of segments can reflect different specific abnormal heart sounds. Moreover, the heart sound signal may also include multiple heartbeat cycles (heartbeats), and some abnormal heart sounds can only be reflected by some specific heartbeat cycles. [0003] Listenin...
