As one embodiment, the X-ray CT device comprises an X-ray tube, a tube voltage generator, an X-ray detector, a data accumulating unit, and an image processing unit. The tube voltage generator applies tube voltage to the X-ray tube. The tube voltage controlling unit controls the tube voltage generator so as to periodically alternate the tube voltage. The X-ray detector is arranged across a subject from the X-ray tube, and detects the X-rays penetrating the subject. The data accumulating unit accumulates first sampling data when a high voltage is applied to said X-ray tube in one cycle by synchronizing with the change in said tube voltage from the data detected by said X-ray detector, and after a predetermined amount of time has passed from said accumulation, accumulates second sampling data when a low voltage is applied to said X-ray tube. The image processing unit creates images based on the accumulated first sampling data and second sampling data.

Provided is a medical image photographing apparatus, including: an X-ray generator configured to radiate an X-ray toward an object that is located in a three-dimensional (3D) virtual grid space which includes a plurality of voxels; an X-ray detector comprising a plurality of detecting elements and configured to detect the X-ray that has propagated through the object; and an image processor configured to process projection image data corresponding to the detected X-ray based on a volume of a first region within the plurality of voxels, through which the X-ray propagates.

A radiographic image capturing apparatus includes the following. A connector coupling detector detects coupling between an external connector and a connector of the radiographic image capturing apparatus. A power supply detector detects an available state of external electric power. A controller controls a turned-on and a turned-off state of the radiographic image capturing apparatus. At a timing when the power supply detector detects a change from the available state to the unavailable state of the external electric power, the controller turns off the radiographic image capturing apparatus if the connector coupling detector detects the coupling between the external connector and the connector of the radiographic image capturing apparatus, or the controller maintains the turned-on state if the connector coupling detector detects the uncoupling between the external connector and the connector of the radiographic image capturing apparatus.

A contactless rotary joint has a stationary and a rotating part. Furthermore at least one of the parts has a rotary joint body made of a plastic material and holding a capacitive data link and a rotating transformer. The rotating transformer has a magnetic core for transmission of electrical power. To prevent interference of the capacitive data link by electrical and/or magnetic fields from the rotating transformer a shield is provided.

According to one embodiment, a medical information processing apparatus includes processing circuitry. The processing circuitry is configured to receive data acquired by scan for an object, and output a reconstructed image data based on the data and a trained model that accepts the data as input data and outputs the reconstructed image data corresponding to the data. The trained model is trained by learning using raw data generated based on a numerical phantom and the numerical phantom.

A gantry rail for a gantry computed tomography (CT) system includes a secondary side of a rotary transformer and an annular body having an annular rolling surface and an annular slip ring surface. The annular body is aligned orthogonal to a longitudinal axis of the gantry CT system. The annular rolling surface has a normal vector that extends radially outward and orthogonal to the longitudinal axis. The annular slip ring surface defines a plane orthogonal to the longitudinal axis, and includes a slot disposed in the slip ring surface. The slot is configured to engage the secondary side of the rotary transformer.
