INTERNAL ORGAN POSITION ESTIMATION DEVICE, CONTROL METHOD FOR INTERNAL ORGAN POSITION ESTIMATION DEVICE, AND CONTROL PROGRAM FOR INTERNAL ORGAN POSITION ESTIMATION DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately identify a position and the like of an internal organ of a patient by using an internal organ in a template.SOLUTION: This device includes: an initial processing unit for deforming a plurality of internal organs in a template, which is a model including a plurality of internal organs, so that a predetermined internal organ of the plurality of internal organs in the template matches a corresponding target internal organ corresponding in volume data; and a deformation processing unit for repeating, the predetermined number of times, first processing of deforming a selection internal organ selected from the plurality of internal organs in the template, according to a corresponding selection internal organ in the volume data, and second processing of deforming each influenced internal organ to be influenced by deformation of the selection internal organ according to deformation which is applied to an influence source internal organ and influences the influenced internal organ in the template, on the basis of data which is stored in a data storage unit and is on a related internal organ being an internal organ influenced by internal organ deformation.
