1. An image processing apparatus, comprising:
processing circuitry configured to:
obtain first medical image data of a region of a patient captured at a first time and second medical image data of the region of the patient captured at a second time different from the first time, the first medical image data and the second medical image data including data representing a bolus of contrast material in a tubular anatomical structure, wherein the bolus of the contrast material has moved between the first time and the second time;
determine an expected motion of the bolus of the contrast material through the tubular anatomical structure between the first time and the second time; and
perform a registration process to obtain a registration of the first medical image data of the region of the patient and the second medical image data of the region of the patient based at least in part on the expected motion of the bolus of the contrast material through the tubular anatomical structure, wherein the registration represents a spatial transformation of the region of the patient as represented in the first medical image data or the second medical image data,
wherein the processing circuitry is further configured to modify at least one of the first image data, the second image data, and/or the registration process based on the expected motion of the bolus of the contrast material, and use the modified first image data, the modified second image data, and/or the modified registration procedure to obtain the registration.
