Problems solved by technology

However, in actual clinical practice, the accuracy of manual segmentation and measurement of left ventricular full parameters will be reduced due to the different manifestations of cardiac structural characteristics in different patients, low image contrast caused by CMR imaging technology, and various types of noise in the data. Low

Abstract

The invention discloses a quantification method of left ventricle full parameters and confidence. The method includes acquiring a heart image to be processed; extracting the left ventricle parameter set corresponding to the heart image and the confidence of each parameter through a trained quantization model. . The present invention outputs the left ventricle parameter set and the confidence degree of each parameter through the quantitative model with the characteristic random loss layer, determines the model uncertainty of the parameters in the characteristic random loss layer, and determines the parameter confidence degree of each left ventricle parameter according to the model uncertainty , output and display the left ventricular parameter set and the confidence of each parameter, so that reference data can be given for the accuracy of each left ventricular parameter, which plays an important role in whether doctors refer to and adopt each left ventricular parameter.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a quantification method of left ventricle full parameters and confidence. Background technique [0002] At present, heart disease has become one of the diseases with the highest morbidity and mortality in the world, which has greatly affected the quality of life of patients and caused a significant burden on the medical system of various countries. According to the latest statistics, more than 50% of the population deaths in the whole European region are caused by cardiovascular diseases; ; In my country, the number of deaths from cardiovascular diseases ranks first among the total causes of death among urban and rural residents, higher than tumors and other diseases. Cardiovascular disease is the leading cause of death worldwide, with 17.9 million deaths from cardiovascular disease in 2015, and this figure will increase to more than 23.6 million by 2030. [000...
