Abstract

The invention discloses a liver medical image registration and fusion method and system, and the method comprises the steps: obtaining an arterial-phase and venous-phase liver CT image sequence chart group for the same liver, and enabling the arterial-phase liver CT image sequence chart group to comprise at least ten arterial-phase liver CT images, the vein phase liver CT image sequence group comprises at least thirty vein phase liver CT images; sequentially registering each arterial phase liver CT image, finding out a vein phase liver CT image with the same cross section from the vein phase liver CT image sequence group, and acquiring at least ten vein phase liver CT images registered with the at least ten arterial phase liver CT images; sequentially fusing each artery-phase liver CT image and one vein-phase liver CT image registered with the artery-phase liver CT image to obtain at least ten liver CT fusion images; and performing sequence three-dimensional reconstruction on the at least ten liver CT fusion images to obtain a liver three-dimensional fusion CT image.

Description

technical field [0001] The present invention relates to the technical field of medical image processing, in particular to a method and system for processing liver medical images. Background technique [0002] The liver is an important organ in the human body. There are many complex piping systems in the liver, such as hepatic artery, hepatic vein, portal vein, and bile duct system. Image processing, visualization research, and biological modeling are of great significance. [0003] The visualization study of the liver can be applied to clinical diagnosis, surgery and liver transplantation. It can help doctors to understand the distribution and connection of the piping system in the liver before surgery, and provide assistance for undiagnosed positioning and surgery. [0004] Medical image registration refers to seeking one or a series of spatial transformations for a medical image to make it spatially consistent with the corresponding points on another medical image. This a...
