X-ray diagnostic apparatus
View Patent ↗An X-ray diagnostic apparatus includes an X-ray generating unit which generates X rays, an X-ray detecting unit which detects X rays transmitted through a subject, an X-ray exposure operating unit which is operated by an operator, and a system control unit which controls the X-ray generating unit in order to start the generation of the X rays from the X-ray generating unit at a time point when a heart rate phase of the subject reaches a specified phase after the X-ray exposure operating unit is operated.
1. An X-ray diagnostic apparatus, comprising:
an X-ray generating unit which generates X rays;
an X-ray detecting unit which detects the X rays transmitted through a subject; and
a control unit which controls the X-ray generating unit in order to change a pulse width of the X rays according to heart rates of the subject.
2. An X-ray diagnostic apparatus, comprising:
an X-ray generating unit which generates X rays;
an X-ray detecting unit which detects the X rays transmitted through a subject; and
a control unit which controls the X-ray generating unit in order to change at least one of a pulse width and a frame rate of the X rays according to a heart rate phase of the subject.
3. The X-ray diagnostic apparatus according to claim 2 , wherein the control unit alternates the pulse width of the X rays between a first pulse width and a second pulse width longer than the first pulse width according to the heart rate phase of the subject.
4. The X-ray diagnostic apparatus according to claim 3 , wherein the control unit sets the pulse width of the X rays to the second pulse width for predetermined phase periods.
5. An X-ray diagnostic apparatus, comprising:
an X-ray generating unit which generates X rays;
an X-ray detecting unit which detects the X rays transmitted through a subject; and
a control unit which controls the X-ray generating unit in order to change at least one of a pulse width and a frame rate of the X rays according to heart rates of the subject or a heart rate phase.
