The disclosure has an object to provide a medical-data processing device that allows generation of an MIP image suitable for diagnosis. With the medical-data processing device of the disclosure, intensity of a body surface region in three-dimensional space data is adjusted. The body surface region corresponds to a body surface of a stereoscopic image of a subject. Since the intensity of the body surface region is adjusted to be decreased, the maximum intensity is selected from a portion except for the body surface region to generate the MIP image. This prevents the body surface of the subject from appearing upon generating the MIP image. Therefore, the MIP image is obtainable having excellent visibility to the inside of the subject.

In the X-ray CT system according to an embodiment, a control means displaces and images imaging regions in the subject by controlling a top board driver and an imaging means such that the X-rays are projected onto the subject every time a top board is moved by a predetermined transfer amount. An acquiring means acquires projection data of the respective imaging regions. A reconstruction means, based on the projection data, reconstructs tomographic images for each predetermined size of a reconstruction region. In the scan control mode, the control means outputs the transfer amount corresponding to this mode to the top board driver. In the reconstruction control mode, the control means outputs the size of the reconstruction region corresponding to this mode to the reconstruction means.

The present invention provides a latching mechanism for an x-ray tube assembly comprising a rotary plate, a first spring-loaded latch and a second spring-loaded latch which are disposed diametrically. The rotary plate comprises a first receiving portion and a second receiving portion spaced from each other by 90°. The first spring-loaded latch configured to be pressed removably into the first receiving portion to lock the x-ray tube assembly in a first position and the second spring-loaded latch is configured to be pressed removably into the second receiving portion to lock the x-ray tube assembly in a second position. According to the present invention, it is possible tomake manufacturing tolerance control and assembly of the x-ray imaging system much simpler and easier.
