Embodiment Construction
[0023] Below in conjunction with accompanying drawing and embodiment, technical solution of the present invention is described further:
[0024] This embodiment provides a multimodal liver tumor segmentation method based on MR and CT, the method comprising:
[0025] Step 1. Obtain the original abdominal MR image sequence and the original abdominal CT image sequence, and perform a preprocessing operation on the original abdominal MR image sequence and the original abdominal CT image sequence to obtain a multimodal image sequence.
[0026] In the embodiment of the present application, the preprocessing operation includes: performing bias field correction on the original abdominal MR image sequence to obtain the first MR image sequence. Uniformity is an unavoidable magnetic field effect, which will lead to uneven image range in the same tissue. In order to improve the accuracy of subsequent results, it is necessary to perform bias field correction on the original abdominal MRI im...
