Abstract

Provided are an image processing apparatus, an operation method of the image processing apparatus, and an operation program of the image processing apparatus that can perform registration of an ultrasound image (13) and a three-dimensional image such that a registration result does not fall into a local solution and a clearly incorrect registration result is not output.An acquisition unit acquires a CT image of a patient. A generation unit acquires a US image of the patient by generating the US image from an echo signal. A selection unit repeatedly selects a plurality of reference points from a first point group of the US image and a plurality of target points from a second point group of the CT image a plurality of times. A derivation unit derives a candidate parameter each time the reference point and the target point are selected. A determination unit determines whether the candidate parameter satisfies a constraint condition related to a position and a posture of an ultrasound probe (10) at the time of capturing the US image.
