An X-ray diagnosis apparatus according to an embodiment includes a processing circuitry. The processing circuitry is configured: to determine a region corresponding to a target object in an X-ray image, on the basis of the X-ray image; to calculate a statistical value related to the region, on the basis of a plurality of pixel values included in the region; and to set an X-ray condition related to generating X-rays, on the basis of the statistical value.

X-ray diagnosis apparatus and X-ray condition setting method

According to an embodiment, there is provided that processing circuitry configured to determine a first radiation timing at which a subject is irradiated with an X-ray, based on information on motion of an object in X-ray image data, the information on motion being calculated by the X-ray image data, the X-ray image data being associated with an electrocardiographic waveform of the subject, and repeatedly irradiate the subject with an X-ray at the first radiation timing per cycle of the electrocardiographic waveform of the subject.

X-ray diagnosis apparatus

An X-ray diagnostic apparatus of an embodiment includes processing circuitry. The processing circuitry determines a concentration of a contrast agent in contrast-enhanced image collection based on first reference information in which a recommended contrast in a contrast-enhanced image is associated with each region of interest to be subject to collection of the contrast-enhanced image, and on second reference information that indicates a relation among a generation condition of an X-ray, a concentration of a contrast agent, and a contrast. The processing circuitry calculates setting information of an injector to inject a contrast agent to the subject based on the determined concentration of a contrast agent.

X-ray diagnostic apparatus and medical-information processing apparatus

According to one embodiment, a gesture detection supporting system for an X-ray diagnosis includes memory circuitry, a sensor, processing circuitry and an attaching instrument. The memory circuitry stores an operation content of an X-ray diagnostic apparatus. The operation content is related to a gesture by a user. The sensor senses a gesture. The processing circuitry detects the gesture, based on an output from the sensor; acquire the operation content of the X-ray diagnostic apparatus, from the memory circuitry, based on a detection result of the gesture; and output operation information to the X-ray diagnostic apparatus, based on the operation content. The attaching instrument attaches the sensor to a ceiling of an examination room, an arm for driving an X-ray tube and an X-ray detector, an intravenous drip stand, an injector of a contrast agent, an X-ray protective board and/or a display for displaying an X-ray image.

Gesture detection supporting system for X-ray diagnosis

An X-ray diagnostic apparatus includes a display, a holding device, bed device, a gesture detecting device and a processing circuitry. The holding device includes an X-ray irradiator, an X-ray detector, and a supporter that supports the X-ray irradiator and the X-ray detector. The bed device is available to place an object on. The gesture detecting device recognizes a gesture of a person. The processing circuitry identifies a state of the X-ray diagnostic apparatus based on at least one of the display, the X-ray irradiator, the X-ray detector, the holding device and the bed device, determines an operation detail based on a combination of the identified state and the recognized gesture, and operates at least one of the display, the holding device, the bed device, a speaker and a room light according to the determined operation detail.

X-ray diagnostic apparatus

An X-ray diagnosis apparatus detects X-rays output from an X-ray source and transmitted through a subject, and generates images of the inside of the subject, and comprises a detector, an X-ray intensity distribution data generator, and an entrance dose distribution data generator. The detector detects the intensity of the X-rays output from the X-ray source. The X-ray intensity distribution data generator generates X-ray intensity distribution data showing the X-ray intensity for each of a plurality of subdomains of an X-ray irradiation field from the X-ray source based on the detection outcome by the detector. The entrance dose distribution data generator generates entrance dose distribution data showing the dose of X-rays output from the X-ray source and irradiated onto the subject, based on the X-ray intensity distribution data.
