Tumor heterogeneity atlas analysis visualization method and system based on adaptive grid

The invention discloses a tumor heterogeneity atlas analysis visualization method and system based on an adaptive grid, and relates to the field of magnetic resonance image processing, and the method comprises the steps: obtaining a discrete magnetic resonance image of a tumor tissue; constructing an initialized discrete multi-dimensional grid, calculating to obtain multi-dimensional spectrum information of tissue components, and performing adaptive adjustment on the initialized discrete multi-dimensional grid to obtain an updated discrete multi-dimensional grid; multi-dimensional spectrum information is calculated again based on the updated discrete multi-dimensional grid, and the multi-dimensional spectrum information obtained through current calculation is compared with the multi-dimensional spectrum information obtained through last calculation; adjusting the discrete multi-dimensional grid updated last time again according to the multi-dimensional spectrum information obtained through current calculation
