[Preliminary experimental analysis of myocardial function evaluation based on integrated backscatter].
OBJECTIVE
To demonstrate the feasibility of the method to detect myocardial function based on integrated backscatter.


METHODS
Using the experimental system developed by our research group, the RF signal of B-mode image was sampled and digitized. Wavelet transform method was adopted for cyclic variation of integrated backscatter (CVIB) calculation. The CVIB image of the region of interest (ROI) was obtained.


RESULTS
The CVIB results of 11 cases with myocardial infarction were provided by data and image. Results of 23 normal people including 8 middle-aged and 15 young were also given for comparison.


CONCLUSIONS
The method based on integrated backscatter can differentiate ischemic myocardium from normal people and it has potential to be used in clinic.
