Document Type and Number:
Japanese Patent JP7015113
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus, a control method of the X-ray diagnostic apparatus, and an image processing apparatus in which the variation of an X-ray dose passing through an interested area in a subject can be suppressed.SOLUTION: An X-ray diagnostic apparatus concerning the present embodiment includes: an X-rays irradiation unit for making irradiation of X-rays toward a subject; an acquisition unit for repeatedly acquiring the X-ray image of the X-rays passing through the subject according to the irradiation of the X-rays irradiation unit; a setting unit for setting a first interested area being an area for use in control of the X-rays irradiation unit in the X-ray image; a generation unit for performing addition processing to apply and add the weight provided with the weighting value larger than 0 according to the position in the first interested area on each pixel value in the first interested area of the X-ray image according to acquisition of the X-ray image in the acquisition unit, and generating a control value based on the value obtained in the addition processing; and a control unit for controlling the X-rays irradiated by the X-rays irradiation unit so that the control value may come close to a predetermined value.SELECTED DRAWING: Figure 1
