Abstract: A medical image diagnosis apparatus according to an embodiment includes an ultraviolet light source, processing circuitry, and an imaging equipment. The ultraviolet light source emits an ultraviolet ray. The processing circuitry controls irradiation of the ultraviolet ray to an irradiation object irradiated with the ultraviolet ray in an examination room by moving a position of the ultraviolet light source relatively with respect to the irradiation object. The imaging equipment acquires a medical image of a subject.

Abstract: A computerized tomography apparatus is disclosed which reconstructs a tomography image of data from multi-directional projection data in a period of time less than the time required for a scan operation for data acquisition and displays the tomography image after a lapse of a given period of time from the termination of the scan operation. This avoids the time interval between scan and image display becoming irregular. Accordingly, tomography images can be displayed successively like motion picture to observe the internal movements of a section of a human body under examination in real time.

Abstract: A computer tomography apparatus of the present invention can select one of an ON state in which X-ray radiation is performed to continuously acquire projection data and an OFF state in which acquisition of projection data is stopped, and even in the OFF state, rotation of an X-ray tube is continued, thus allowing quick switching from the OFF state to the ON state.

Abstract: In an X-ray CT scanner, a first field of view corresponding to a reconstructed area of an image to be displayed is set. An original image data are reconstructed on the basis of a plurality of projection data in a patient in response to the first field of view. Whether or not an imaged region in the patient is larger than the first field of view is judged according to referring the original image data. A second field of view including the imaged region wholly is set in case that the imaged region is larger in area than the first field of view. Beam hardening correction data are produced on the basis of the projection data in the second field of view. The projection data are processed into the image corresponding to the first field of view with an aid of the correction data.

Abstract: A method and an apparatus for specifying slice planes in an X-ray CT, capable of specifying a slice plane corresponding to the desired tomographic image easily and accurately. In the apparatus, scans of the body to be examined are carried out and the projection data stored in the large capacity memory first. Then, a scanogram of the body to be examined is displayed, on which a cursor is controlled in order to specify the desired slice planes corresponding to the desired tomographic images to be reconstructed. Then, the desired tomographic images are reconstructed for the desired slice planes indicated by the cursor by using an appropriate part of the projection data stored in the memory which corresponds to the desired slice planes indicated by the cursor. Either one of the helical scan and the multi-scan can be used for collecting the data to obtain the scanogram and the tomographic images.
