A Novel Method and Data Storage Medium for Processing Liver Cancer Data

The work discloses a method, system and storage medium to process data from liver cancer lesions. The method includes the following steps: collecting energy spectrum CT images of different phases from patients with liver cancer; preprocessing the energy spectrum CT images to obtain the preprocessing image; perform liver segmentation on the preprocessed image to image liver regions at different phases; perform images of liver regions in different phases; segment of liver cancer lesions in the images of the recorded liver regions. The work provides various imaging information by collecting energy spectrum computed tomography images of different phases of liver cancer patients, and then automatically aligns the images in the arterial phase and venous phase in the pre-processing process, to reduce the registration difficulty. Finally, the liver area is segmented first, and then registration is performed to speed up the registration speed, so as to realize the function of accurately segmenting the liver cancer lesion area. © 2023 IEEE.
