Embodiment Construction
[0035] The present invention will be described in more detail and complete below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.
[0036] like figure 1 As shown, a kind of brain tumor image segmentation method based on multi-sequence MR image correlation information of the present invention comprises the following steps:
[0037] S1: Obtain MR images of different sequences in the same case, including T1 (longitudinal relaxation time), T2 (transverse relaxation time), T2WI+FLAIR (T2-weighted imaging), and T1WI (T1-weighted imaging) four imaging sequences.
[0038] S2: Select the brain tumor area of one of the serial MR images as the tumor seed point. The seed point selection method only needs to select one of the serial MR images, and does not need to be selected in all the serial MR images. The s...
