[0029] figure 1 It is a block diagram showing the configuration of an X-ray diagnostic apparatus according to one embodiment. figure 1 An X-ray diagnostic apparatus 100 called an angio is shown. The X-ray diagnostic apparatus 100 includes: an X-ray generation unit 10 that generates X-rays to the subject P; and an X-ray detection unit 20 that two-dimensionally detects the X-rays transmitted through the subject P, and generates X-rays based on the detection results. Project data.

[0030] The X-ray generation unit 10 includes an X-ray irradiation unit having an X-ray tube 11 and an X-ray diaphragm 12 (X-ray diaphragm unit), a high-voltage control unit 13 , and a high-voltage generator 14 . The X-ray tube 11 is a vacuum tube that generates X-rays. The electrons emitted from the cathode (filament) are accelerated by high voltage and hit the tungsten anode to generate X-rays. The high-voltage control unit 13 controls the high-voltage generator 14 according to the instruction sig...

[0066] Next, an X-ray diagnostic apparatus according to a second embodiment will be described. The second embodiment is an embodiment in which the rotation of the X-ray diaphragm 12 is instructed by a user's operation using a button. Figure 9 It is a figure explaining the change process of ROI in 2nd Embodiment.

[0067] Such as Figure 9As shown in (a), an equipment image 53 as a target is displayed on the ROI perspective image 51 in which the irradiation range is limited by the diaphragm blades 121A and 121B. Next, if Figure 9 As shown in (b), the user operates the operation unit 34 to rotate the ROI (corresponding to the frame of the ROI image 51 ). The image processing unit 32 notifies the information of the rotated ROI to the diaphragm mechanism control unit 41 via the system control unit 33 .

[0068] For example, an operation button 341 for instructing ROI rotation is provided on the operation unit 34 , and each time the user presses the operation button 341 , the...

[0085] Next, an X-ray diagnostic apparatus according to a third embodiment will be described. The third embodiment is an embodiment in which parallel lines are drawn near the device image 53 in response to a user's operation, and the X-ray diaphragm 12 is rotated using the drawn lines. Figure 13 It is a figure explaining the change process of ROI in 3rd Embodiment.

[0086] Such as Figure 13 As shown in (a), the equipment image 53 is displayed on the ROI perspective image 51 in which the irradiation range is limited by the diaphragm blades 121A and 121B. Next, if Figure 13 As shown in (b), the user operates the mouse 342 to draw a straight line 65 approximately parallel to the longitudinal direction of the mouse image 63 near the device image 53 . The image processing unit 32 determines in which part of the ROI perspective image 51 the straight line 65 is drawn, and rotates the ROI so that one side of the ROI is parallel to the drawn straight line 65 . Then, the image p...

Abstract

An x-ray diagnostic device of an embodiment of the present invention is equipped with the following: an image pick-up unit comprising an x-ray tube for emitting x-rays to a subject and an x-ray detector for detecting the x-rays that pass through the subject; an x-ray aperture unit that is disposed between the x-ray tube and the x-ray detector, and that has a plurality of aperture blades and is rotatable; an image processing unit for generating a transparent image of a region of interest set according to the x-ray aperture unit; and a control unit that controls individually the plurality of aperture blades so that the long side of the opening formed by the plurality of aperture blades is oriented in the longitudinal direction of a target object in the transparent image.

Description

technical field [0001] An embodiment of the present invention relates to an X-ray diagnostic apparatus having an X-ray generating unit and an X-ray detector, and relates to an X-ray diagnostic apparatus that limits the irradiation range by rotating and moving the aperture blades of the X-ray aperture to reduce the amount of radiation. And X-ray diagnosis support method. Background technique [0002] Conventionally, in intravascular treatment, angiographic examination, etc., a catheter is inserted into a blood vessel from, for example, the groin, and the catheter is advanced in the blood vessel to deliver it to a target site. When the catheter (or guide wire guiding the catheter) is advanced to the target position, an X-ray fluoroscopic image is displayed so that the catheter or guide wire is guided to the affected area while viewing the displayed image. [0003] In addition, in an X-ray diagnostic apparatus, an X-ray tube and an X-ray detector (generally a flat detector cal...
