According to one embodiment, an X-ray diagnostic apparatus includes an X-ray movable diaphragm and processing circuitry. The X-ray movable diaphragm limits an irradiation field of an X-ray. The processing circuitry sets an FOV size related to the irradiation field, sets a virtual field of view having the FOV size, the virtual field of view being able to include an outside region of an X-ray detection region and at least a part of the X-ray detection region, and controls the X-ray movable diaphragm so as to apply the X-ray to a common region between the virtual field of view and the X-ray detection region.

X-ray diagnostic apparatus

An X-ray apparatus includes a light emitting unit, input interface circuitry, and processing circuitry. The light emitting unit includes a light source. The input interface circuitry inputs an X-ray condition. The processing circuitry controls an emission state of the light emitting unit to change to one of at least three states based on the X-ray condition.

X-ray diagnosis apparatus

An X-ray diagnostic apparatus according to an embodiment includes a bed that has a top board on which an object is placed, a console configured to manipulate an actuation of the bed in an inverting direction, in which the object is inclined to locate a head lower than a foot, and an actuation of the bed in a raising direction, in which the object is inclined to locate the head higher than the foot, and a processing circuitry configured to receive an input from the console and control an actuation of the bed, and the processing circuitry determines whether the head of the object is located closer to one shorter side of the bed or to another shorter side of the bed, and changes a control of an actuation of the bed programmed in the console based on a result of the determination.

Operating information processing unitsends beam-limiting control unitthe calculated moving amount. Upside beam-limiting control unitto right side beam-limiting control unit of beam-limiting control unitmakes the moving amount at the center of the exposure fieldprescribed-times ((H/H) times in FIG.), calculates the moving amount of each diaphragm blade unitin the upper part, the lower side, and the left part and the right part respectively.

A bed apparatus includes a bed, a bed lifting unit that lifts the bed, and a bed stop position control unit that controls the bed lifting unit such that the bed stops at a position out of the maximum stroke according to a predetermined stop condition.

Bed apparatus, X-ray diagnostic apparatus, and method of controlling a bed for X-ray diagnostic apparatus

A medical image radiography apparatus includes a radiography system for taking a medical image of a subject, a supporting mechanism for supporting the radiography system in various radiography positions, a memory unit for storing a plurality of radiography positions, together with their order relation, as sequential automatic positioning data, and a controller for controlling the supporting mechanism on the basis of the sequential automatic positioning data in order to change a radiography position sequentially. In this manner, the plurality of radiography positions are stored, together with their order relation, as the sequential automatic positioning data. When taking a radiograph, the radiography position is sequentially changed in accordance with the sequential automatic positioning data. As a result, the operability concerning a change in the radiography position is improved more than in the conventional case wherein a preset button is repeatedly selected.
