Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an X-ray diagnostic apparatus, and more particularly to an X-ray flat panel detector (hereinafter simply referred to as a flat sensor) as X-ray image detecting means. The present invention relates to a technology which is effective when applied to a multi-purpose flat sensor supporting mechanism. 2. Description of the Related Art A conventional X-ray diagnostic apparatus is provided with a support frame which can be turned upside down (rotated) on a base. In the front of the support frame, a column for supporting the X-ray tube apparatus and a table on which a subject is mounted are provided. The table is provided with a platform on which the subject rides and grip bars on both sides of the subject. Further, an X-ray imaging apparatus (including an image intensifier: II) is incorporated between the table and the support frame. Further, an X-ray tube apparatus is installed on the upper side of a table on which a subject is laid, and an X-ray imaging apparatus is installed on a lower side. The image intensifier (II) is provided at the center of emission of X-rays from the X-ray tube apparatus. In a normal state, the image intensifier and the television camera and the television monitor are used to perform fluoroscopic / photographing observation. I have to. In recent years, X-ray apparatuses for general radiography (X-ray apparatuses for chest radiography) equipped with a semiconductor type flat sensor, which is a new radiographing device, are becoming widespread. In addition, X-ray televisions in which a conventional screen / film (S / F) rapid-moving device is replaced with the above-described flat sensor for the purpose of improving a digital image of a photographing system and fully digitizing the system have begun to be released. [0005] The flat sensor is
Since it is thinner and lighter than an image intensifier (II), its supporting method is easy but expensive. This problem occurs even in a system that combines the flat panel sensor and an X-ray television.
Conventional I. I. If it becomes possible to perform chest imaging that could not be done with a system that combines
Use value increases. An object of the present invention is to provide a technique which can use a flat sensor of an X-ray diagnostic apparatus for multiple purposes. The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings. [0007] The outline of the invention disclosed in the present application will be briefly described as follows.
According to the present invention, a base is provided with a support frame that can be tilted up and down, a table on which the subject lies, and an X-ray tube device installed on the upper side of the table, and an X-ray tube on the lower side. In the X-ray diagnostic apparatus provided with a plane detector, the X-ray plane detector is supported by a support arm so as to be tiltable and rotatable, and the support arm is supported by a movable frame so as to be rotatable about a fulcrum.
The X-ray diagnostic apparatus is characterized in that the X-ray diagnostic apparatus is developed at a predetermined position outside the main body of the X-ray diagnostic apparatus. [0008] With this configuration, the X-ray plane detector (for example, a plane sensor) of the X-ray diagnostic apparatus is supported so as to be able to rotate, tilt, rotate and open and close (deploy). The vessel can be used for multiple purposes. For example, by rotating and opening (deploying) a flat sensor installed for X-ray fluoroscopy and setting the flat sensor at a predetermined position outside the X-ray diagnostic apparatus main body, the one expensive flat sensor can be moved to, for example, a chest. It can also be used for photography. Hereinafter, the present invention will be described in detail with reference to the drawings together with the embodiments (examples) of the present invention. In all the drawings for describing the embodiments (examples) of the present invention, those having the same functions are denoted by the same reference numerals, and their repeated description will be omitted.

In the line diagnostic apparatus, the flat sensor 9 is supported by a support arm (opening / closing arm) 26 via a rotatable and tiltable bearing 22. The support arm (opening / closing arm) 26 is supported by the moving frame 21 so as to be freely rotatable and openable (deployable) about a fulcrum 27 as an axis, and from the position where the flat sensor 9 is installed on the moving frame 21 during X-ray fluoroscopy. It is set to a position outside the apparatus main body by rotating and opening (deploying). On the bases 1A and 1B of the X-ray diagnostic apparatus, a left support frame 2 and a right support frame 3 are provided so as to be able to be turned upside down (tilted). The left support frame 2 is provided with a first rail 31, and the right support frame 3 is provided with a second rail 32. The left support frame 2 and the right support frame 3 are tilted (inclined) by a first gear 43 (rotation) and a second gear 44.
(Rotation). The first
The gear 43 is driven to rotate by a prime mover 42 with a speed reducer.
The moving frame 21 includes a moving roller 45 fitted on a first rail 31 provided on the left supporting frame 2 and a moving bearing fitted on a second rail 32 provided on the right supporting frame 3. Reference numeral 46 denotes a support movably in the longitudinal direction (front-back direction). The column 5 is attached to the moving frame 21. The X-ray tube device 4 is attached to the support 5 so as to be above the table 6 on which the subject lies. That is, on the front side of the left support frame 2 and the right support frame 3, a column 5 for supporting the X-ray tube device 4 and a table 6 on which a subject is mounted are provided. The table 6 is provided with a step 7 on which the subject rides and grip bars 8 on both sides of the subject. Further, a flat sensor 9 is incorporated between the table 6 and the left support frame 2 (and the right support frame 3). The flat sensor 9 is provided at the center of the X-ray radiation from the X-ray tube device 4. In a normal state, the flat sensor 9 performs photographing observation and fluoroscopic observation with the television monitor (not shown). I have to. The flat sensor 9 is supported by a support arm (opening / closing arm) 26 so as to be tiltable and rotatable. The tilt / rotation and fixed support are performed by a tilt / rotation lever 23. The support arm (opening / closing arm) 26 includes:
The movable frame 21 is opened and closed (deployed) with the fulcrum 27 as an axis from a position provided on the movable frame 21 at the time of X-ray fluoroscopy with the fulcrum 27 as an axis, and set at a position outside the apparatus body ( (See FIG. 3). In addition, during X-ray fluoroscopy, the moving frame 2
