Radiation imaging system and method for controlling the same

摘要

In a radiation imaging system performing a difference process using a stored mask image based on a radiation image obtained before a contrast agent is injected and a radiation image obtained after the contrast agent is injected, a controller displays a first graphic representing a first timing when irradiation of a radial ray is started, a second graphic representing a second timing when the mask image is stored, and a third graphic representing a third timing when the contrast agent is injected in this order along a time axis and controls the second and third timings by the second and third graphics. The controller moves, when one of the second and third graphics is moved along the time axis, the other of the second and third graphics such that an interval between the first and third graphics becomes larger than an interval between the first and second graphics.

1. An X-ray imaging system which performs a difference process using a mask image which is instructed by a calculation unit to be stored in a storage unit and which is based on an X-ray image which is obtained before a contrast agent is injected by an injection device to a certain portion of an object and which is selected from among fluoroscopic images obtained by an X-ray imaging apparatus on the basis of an X-ray which is irradiated by an X-ray source and which passes the certain portion, and an X-ray image which is obtained after the contrast agent is injected and which is selected from among the fluoroscopic images, the X-ray imaging system comprising:
a controller configured to display a first graphic representing a first timing when irradiation of an X-ray from the X-ray source is started, a second graphic representing a second timing when the mask image is stored, and a third graphic representing a third timing when injection of the contrast agent performed by the injection device is started in a display unit in this order along a time axis displayed in the display unit, configured to control the second timing by a position of the second graphic relative to the time axis, and configured to control the third timing by a position of the third graphic relative to the time axis, wherein, when one of the second and third graphics is moved along the time axis, the controller moves the other of the second and third graphics such that an interval between the first and third graphics becomes larger than an interval between the first and second graphics.
