Embodiment Construction
[0040] The following is a detailed description of the embodiments of the present invention. This embodiment is carried out based on the technical solution of the present invention, and provides detailed implementation methods and specific operation processes.
[0041] In the embodiment of the present invention, multiple cardiac magnetic resonance short-axis cine images of different time phases and different parts are used to segment the right ventricle to obtain the specific implementation process of the final segmentation result. Among them, the cardiac magnetic resonance cine short-axis image data used for right ventricle segmentation comes from the magnetic resonance system and is obtained through the SSFP sequence. In the experimental data, there are 7 males and 3 females, ranging in age from 14 to 75 years old. Specific imaging parameters: image size 256×256, slice thickness 6-8mm, slice spacing 2-4mm, each set of data contains 6-10 slices, each slice has 20-28 phases, an...
