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

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.

X-ray diagnosis apparatus and dose distribution data generation method

In an embodiment, an X-ray diagnostic apparatus includes an image capturing unit which captures an X-ray image of a subject on a tabletop, a movement mechanism which moves the tabletop and the image capturing unit relative to each other, an acquisition unit which acquires device position information on the tabletop and the image capturing unit in capturing the X-ray image, a display unit which displays the X-ray image captured by the image capturing unit, an input unit which inputs added information to be added to the X-ray image displayed on the display unit, and a management unit which manages the X-ray image captured by the image capturing unit, the device position information acquired by the acquisition unit, and the added information inputted by the input unit in association with one another.

X-ray diagnostic apparatus

An X-ray diagnostic apparatus according to an embodiment includes a support mechanism, bed, dosimeter, dose decision unit, dose distribution generation unit and display unit. The support mechanism movably supports an X-ray tube generating X-rays over a plurality of times in a predetermined period and an X-ray detector detecting X-rays transmitted through an object. The bed includes a top on which the object is placed. The dosimeter measures a total dose over the period. The dose decision unit decides doses respectively corresponding to times of generation of the X-rays in the period based on the total dose and an X-ray irradiation condition. The dose distribution generation unit generates a dose distribution based on a position of the support mechanism, a position of the bed, and the doses. The display unit displays the dose distribution.

X-ray diagnostic apparatus and dose distribution generation method

An X-ray imaging apparatus is configured to subtract a first X-ray image from a second X-ray image to generate a first subtraction image showing information on a blood vessel, calculate an amount of pixel shift between the first X-ray image and the third X-ray image, subtract the first X-ray image from the third X-ray image to generate a second subtraction image showing information on an insertion instrument, and combine the first subtraction image with the second subtraction image to generate a synthetic image by performing a pixel shift correction based on the amount of pixel shift.
