Japanese Patent JP7311109

B2

A medical image processing device of an embodiment includes a first image acquirer, a second image acquirer, a generator, and a calculator. The first image acquirer acquires a first fluoroscopic image of a patient. The second image acquirer acquires a second fluoroscopic image according to radiation with which the patient is irradiated at a time point different from a time point of acquisition of the first fluoroscopic image from a photography device that detects radiation with a detector and performs an imaging process. The generator generates a reconstructed image obtained by reproducing the second fluoroscopic image from the first fluoroscopic image virtually arranged in a three-dimensional space on the basis of an installation position of the detector in the three-dimensional space. The calculator obtains a suitable position on the first fluoroscopic image in the three-dimensional space on the basis of a degree of similarity between the second fluoroscopic image and the reconstructed image. The generator generates the reconstructed image which is for use in the calculator and has a range larger than a range corresponding to the second fluoroscopic image.
