Problems solved by technology

[0006] However, in the technique of superimposing a moving image on a still image to generate a composite image as described above, since there is a time difference in the timing of shooting between the still image and the moving image stored in advance, the patient's body Due to activities and other reasons, the subject's positional relationship with respect to still images and moving images deviates, which may invalidate the composite image
Therefore, although the region of interest is changed according to the movement of the subject, at the same time, if the still image stored in advance has not been changed, the positional relationship between the region of interest and its surrounding regions becomes incorrect, and their positions cannot be correctly grasped. Positional relationship
In addition, when changing the still image stored in advance, since it is necessary to take a fluoroscopic image of the surrounding area again, the radiation dose increases and the operability also decreases.

no. 1 Embodiment approach ）

[0016] refer to Figure 1 to Figure 4 The first embodiment will be described.

[0017] Such as figure 1 As shown, the X-ray image diagnostic apparatus 1 according to the first embodiment includes: a bed 2 on which a subject P such as a patient is placed; an imaging unit 3 for imaging the subject P on the bed 2; The moving device 4 that moves the unit 3 to the shooting position; the image processing device 5 that processes X-ray images; the display unit 6 that displays various images such as X-ray images; and the control device 7 that controls each unit.

[0018] The bed 2 includes a rectangular bed surface 2 a on which the subject P is placed, and a bed drive unit 2 b that supports the bed surface 2 a and moves in the horizontal direction and the vertical direction. The bed surface drive unit 2b has a movement mechanism for moving the bed surface 2a, a drive source for providing a driving force for the movement, and the like. In this bed 2, the bed surface 2a is moved to a ...

no. 2 Embodiment approach ）

[0061] refer to Figure 5 The second embodiment will be described.

[0062] The second embodiment is basically the same as the first embodiment. Therefore, in the second embodiment, the parts that are different from those in the first embodiment will be described, and the description of the parts that are the same as those described in the first embodiment will be omitted.

[0063] Such as Figure 5 As shown, when the image processing device 5 sets the region of interest R1 in the X-ray image (original image) G1 of the entire X-ray irradiated region, the image processing unit 5b uses the image processing unit 5b from the X-ray image G1 stored in the image storage unit 5c, The X-ray image G2a of the peripheral region R2 other than the region of interest R1 is generated in the entire X-ray irradiation region, and the X-ray image G2a of the peripheral region R2 and the X-ray image G2b of the region of interest R1 are synthesized to generate a composite image G2. This synthesiz...

Abstract

An X-ray image diagnosis apparatus according to an embodiment includes: an image processing unit configured to create a synthesized image by synthesizing an X-ray image of a region of interest inside a given region and an X-ray image of a peripheral region excluding the region of interest in the given region, wherein when the region of interest is changed, the image processing unit acquires an X-ray image of a changed region which is in the region of interest before the change and is changed to the peripheral region, from the X-ray image of the region of interest before the change, and then superimposes the X-ray image of the changed region on the X-ray image of the peripheral region to create the synthesized image.

Description

[0001] This application is based on Japanese Patent Application No. 2011-259929 (filing date: 11 / 29 / 2011), and the right of priority is claimed based on this application. This application incorporates the entire content of this application by reference. technical field [0002] Embodiments of the present invention relate to an X-ray image diagnostic device. Background technique [0003] An X-ray image diagnostic apparatus is a device that irradiates an object such as a patient with X-rays with an X-ray irradiator, detects the X-rays transmitted through the object with an X-ray detector, and obtains an X-ray image of the object. As this X-ray image diagnostic apparatus, for example, an X-ray image diagnostic apparatus has been developed that includes a C-arm or the like that holds an X-ray irradiator and an X-ray detector in a facing state, and moves the X-ray irradiator and X-ray detector to At the imaging position of the subject on the bed, an X-ray image of the site of in...
