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.

X-ray CT (computed tomography) device

An X-ray CT apparatus has a plurality of projectors, a reception unit, a setting unit, a supporter, and a scan execution unit. The projectors each have a light source on a circumference having a same radius as a rotation radius of an X-ray focal point of an X-ray irradiator and each irradiate laser light having an irradiation range simulating an irradiation range of the X-ray. The reception unit receives an instruction for three-dimensionally sliding the projectors as one body. The setting unit sets a position of the projectors. The supporter supports a table and three-dimensionally slides the table by a difference between a position of a center of the circumference of the set projectors and a position of a rotation center of the X-ray focal point of the X-ray irradiator. The scan execution unit executes a scan with the table after the sliding as a scan position.

X-ray CT apparatus and control method of X-ray CT apparatus

An X-ray CT system of an embodiment includes the following. An imaging region data acquisition part is configured to acquire a first imaging region and a second imaging region that have different widths from each other in the body axial direction based on a scanogram as imaging regions for performing scan imaging. An irradiation field control part is configured to obtain irradiation fields for the first and the second imaging regions, and control an irradiation field regulating part corresponding to the relative positions by a moving part so as to realize the irradiation fields obtained for each the imaging region. An X-ray control part is configured to control an X-ray generating part corresponding to the relative positions by the moving part so as to irradiate X-rays to the first and the second imaging regions for the scan imaging.

X-ray CT system and control method for same

A medical apparatus including a main unit including an X-ray CT imaging unit configured to image a patient and a display unit provided on the X-ray CT imaging unit and configured to display a name of the patient to be imaged, and a console unit remote from the main unit and including an input unit configured to input condition information of the main unit and individual information including the name of the patient. The console also includes a control unit configured to extract at least one item including the name of the patient in the individual information from the inputted condition information and the inputted individual information. The display unit is configured to display the extracted item including the name of the patient on a screen.

X-ray CT apparatus having a display to display information inputted from a remote operator console

An X-ray computed tomography apparatus of this invention includes a first data detecting system which includes a first X-ray tube and a first X-ray detector and a second data detecting system which includes a second X-ray tube and a second X-ray detector. A reconstructing unit reconstructs image data on the basis of the data detected by at least one of the first and second data detecting systems. A monitoring unit monitors the first data detecting system. In a period during which the first data detecting system is normal, data acquisition is performed by both the first and second data detecting systems. In a period during which the first data detecting system is faulty, data acquisition is performed by the second data detecting system alone.

X-ray computed tomography apparatus

An X-ray computed tomography apparatus includes a first X-ray tube configured to generate X-rays with which a subject to be examined is irradiated, a first X-ray detector configured to detect X-rays transmitted through the subject, a second X-ray tube which generates X-rays with which a treatment target of the subject is irradiated, a rotating mechanism which rotates the first X-ray tube, the first X-ray detector, and the second X-ray tube around the subject, a reconstructing unit configured to reconstruct an image on the basis of data detected by the first X-ray detector, and a support mechanism which supports the second X-ray tube. The central axis of X-rays from the second X-ray tube tilts with respect to a body axis of the subject. This makes it possible to reduce the dose on a portion other than a treatment target.
