ABSTRACT:
X-ray detectors of an X-ray CT apparatus provides photographing image data to a medical image forming apparatus. When data for setting a region-of-interest ("ROI") image and CT values of bones are provided through an input data entry unit of the medical image forming apparatus, a system control unit controls a tomographic image reconstruction unit in such a way that the latter eliminates pixels with the CT values from the ROI image. The reconstruction unit provides the same to a monitor unit through a display control unit. The ROI tomographic image is converted into a blood-vessel emphasized tomographic image. A clear ROI image can be obtained for portions even complicatedly tangled with bones and vessels, such as a human head or the like.
