Japanese Patent JP2023026400

A

To solve a problem in a procedure when a CT scan does not include the complete liver volume in a surface-based liver registration in which the liver surface is aligned without considering the internal liver volume.SOLUTION: One method includes receiving a first image and a second image acquired from a patient at different times, in each of the first image and the second image, detecting an upper boundary and a lower boundary of an object in an image coordinate system, based on the upper boundary and the lower boundary of each of the first image and the second image, cropping and padding at least one of the first image and the second image to create an aligned first image and an aligned second image, and executing a registration model on the aligned first image and the aligned second image.SELECTED DRAWING: Figure 7
