Improve the identification of blood vessel regions in medical images with calcified regions or stent regions. The medical image processing device 2 according to one embodiment is characterized in that it includes a blood vessel enhanced image generation processing unit, based on the data of the contrast image corresponding to the imaging area including the blood vessel area, the X-ray high absorption area, and other areas and the imaging data. The data of the non-contrast image corresponding to the area generates the data of the blood vessel enhanced image except the X-ray high absorption area; the reference image generation processing unit generates the reference image including at least the X-ray high absorption area and the above-mentioned blood vessel area according to the data of the contrast image Image data; the combined image generation processing unit, based on the blood vessel enhanced image data and the reference image data, generates a combined image that suppresses or removes the image intensity of the X-ray high absorption region.
Description
technical field [0001] This embodiment relates to a medical image processing device and a medical image processing method. Background technique [0002] Coronary artery stenosis is an obvious indicator of coronary artery disease, and various imaging techniques and diagnostic techniques have been developed in order to identify and visualize the site including the stenosis. [0003] Catheter coronary angiography has traditionally been considered the most accurate imaging technique for the assessment of coronary artery stenosis. Catheter coronary angiography, however, is an invasive procedure requiring positioning of the catheter relative to each coronary ostium, causing discomfort to the patient and possibly some danger. In addition, this technique uses X-ray fluoroscopy with exposure of the patient to high radiation doses of radiation. figure 1 is a diagram showing an example of a 2D image obtained using a known catheter coronary angiography technique. [0004] In addition...
