Abstract

X-rays are applied without administrating an angiographic contrast agent, unadministration image acquiring means (7) acquires an unadministration image of an angiographic contrast agent unadministrated state, X-rays are applied after administrating an angiographic contrast agent, and an administration image acquiring means (8) acquires an administration image of an angiographic contrast agent administered state. The acquired unadministration and administration images are superimposed on one the other by blood vessel trace image acquiring means (9), the image data on the DSA images obtained in the angiographic contrast agent unadministrated and administrated states is processed, and thus a blood vessel trace image is acquired. The acquired blood vessel trace image is black-white inverted by image processing means (10), and blood vessels are displayed in white. A beam hardening filter (4) is inserted. While inserting a guide wire (W) in the blood vessel, X-ray fluoroscopic imaging is performed. The X-ray fluoroscopic image and the blood vessel trace image are superimposed on one the other by image superimposing means (11), and the acquired superimposed image is displayed on a display monitor (15).

Description

Technical field

[0001] The present invention relates to an X-ray diagnostic apparatus. The X-ray diagnostic apparatus has: an X-ray irradiation mechanism such as an X-ray tube for irradiating X-rays to a subject; and detecting X-rays passing through the subject and outputting X-ray detection Signal X-ray detectors and other X-ray detection mechanisms. In particular, it relates to a technology for generating road map images. Background technique

[0002] Take an X-ray fluoroscopy imaging device as an X-ray diagnostic device as an example for description. As a technique for generating a road map image of such an X-ray fluoroscopic imaging device, the following configuration has been conventionally known.

[0003] That is, with the X-ray irradiation from the X-ray tube to the subject, the X-ray detection signal is output from the flat-panel X-ray detector, and based on the X-ray detection signal, the data processing unit obtains the transmitted X-ray of the subject For the X-ray ima...

Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

[0041] figure 1 A diagram showing the overall schematic configuration of an X-ray diagnostic apparatus according to an embodiment of the present invention. An X-ray tube as an X-ray irradiating mechanism for irradiating X-rays is installed above the desktop 1 on which the subject M is mounted. 2. On the other hand, under the table top 1, an X-ray detector 3 as an X-ray detection mechanism that detects X-rays irradiated from the X-ray tube 2 and transmitted through the subject M is provided. In this embodiment, as an X-ray diagnostic apparatus, an X-ray fluoroscopic imaging apparatus is used as an example for description.

[0042] In front of the X-ray irradiation direction of the X-ray tube 2, there is a line quality control mechanism that can switch between the inactive state and the active state to control the energy distribution of the X-rays irradiated from the X-ray...
