Embodiment Construction
[0126] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0127] see figure 1 As shown, the embodiment of the present invention provides a multi-parameter MRI prostate cancer CAD method based on two classifiers, comprising the following steps:
[0128] S1. Automatic detection of candidate lesions:
[0129] The data set containing all cases is divided into sets X, Y, and Z. These three sets contain different cases respectively. Each case in the three sets includes T2WI, DWI, ADC (apparent diffusion coefficient, apparent diffusion coefficient ) of these three MRI sequences, in which ADC is calculated by DWI; the three MRI sequences T2WI, DWI, and ADC in the same case are denoted as I T2 , I DWI , I ADC ;
[0130] The three MRI sequences of each case are preprocessed to make them have the same resolution and size, and the pixels at the same position basically correspond to the same part of...
