Returning to FIG. The frame unit 120 includes a top plate 121 on which a subject (patient) is placed and a frame 122 that holds the top plate 121. Further, a tower base 123 that is located below the tower 113 and holds the tower 113.
The tower base 123 is disposed on a rail (not shown) in the frame 122 held by a support member (not shown) protruding from the tilting base portion 130, and is in the Z-axis direction (vertical direction toward the paper surface). ), The structure is movable together with the tower section 110, and X-ray imaging of an arbitrary part can be performed on the patient placed on the top plate 121.

Further, 124 is an image intensifier for converting an X-ray image, which is irradiated from the tube 111 and transmitted through the patient placed on the top plate 121, into an optical image, 125

It moves in the Z-axis direction together with 3. Each component of the frame unit 120 (top plate 121, frame 122, tower base 123, image intensifier 124, SFD unit 125) has a structure that can be disassembled.
Shows the outer shape of each component after dismantling of the frame part 120 (the described dimensions are an example).

The outer shape of the tilting base portion 130 is shown in FIG.
As shown in 0, the dimensions given are examples. In addition,
Details of how to attach the respective components of the tower base 123, the frame 122, the image intensifier 124, the SFD section 125, and the tilting base section 130 will be described later. Characteristics of the shape of the X-ray fluoroscopic imaging apparatus In the X-ray fluoroscopic imaging apparatus having the above-described components, the tower section 110 and the frame section 120 often interfere particularly with the carry-in port when loading the apparatus. FIG.
Is a diagram showing a relationship between an X-ray fluoroscopic imaging apparatus 1300 placed on a carriage 1301 for loading and a loading port 1302, and a tower for irradiating X-rays from above a patient placed on the top plate 121. The part 110 needs to have a predetermined height, and as a result, the height dimension A is larger than the carry-in port 1302. Further, the frame 122 for mounting the patient is provided with the tilting base portion 13
Since the structure is overhanging from 0, the width B is also larger than the carry-in port 1302. That is, it has a shape that causes interference in the height direction and the width direction with respect to the carry-in port. Relationship between the size of the X-ray fluoroscopic apparatus and the size of the carry-in entrance As shown in FIG. 14, the width dimension of the tilting base portion 130 is C,
When the height dimension of the tilting base section 130 and the frame section 120 is D and the width dimension of the tilting base section 130 and the frame section 120 is B, the X-ray fluoroscopic apparatus has C <D <. It is characterized by having the relationship of B.

On the other hand, statistics of the opening size (width size) of the carry-in entrance in the examination room of various medical institutions into which the X-ray fluoroscopic apparatus is carried in are shown as a frequency distribution as shown in FIG. The horizontal axis represents the opening dimension (width dimension), and the vertical axis represents the frequency. An arrow 1501 in the graph indicates a region where the opening size (width size) of the carry-in port is C or more and less than D, an arrow 1502 indicates a region where the opening size (width size) of the carry-in port is D or more and less than B, and arrow 1
Reference numeral 503 indicates a region where the opening size (width size) of the carry-in port is B or more. That is, according to the graph, the number of those having a carry-in port of less than D and those of B or more is small, and most of them are D or more and less than B. Therefore, regarding the interference in the width direction, it can be understood that if the width dimension when the X-ray fluoroscopic apparatus is disassembled is less than B, it can be carried into many carry-in ports. Structural Features of the X-ray Fluoroscopic Imaging Apparatus As described above, the X-ray fluoroscopic imaging apparatus has the tower section 110, the frame section 120, and the tilting base section 130, each of which has a structure that can be disassembled. At the time of disassembly, the tower portion 110 can be removed relatively easily, but the frame portion 120 is not easily removed for the reasons described below.

FIG. 11 shows details of a method of mounting the respective components of the tower base 123, the frame 122, the image intensifier 124, the SFD section 125 and the tilting base section 130.
The shaded portion in the middle) is held on the tilting base portion 130 by the removable support members 1101 and 1102. In addition, the tower base 123 is the frame 122.
Of the two tires (1103, 1104, 1) that are arranged on the three rails (portions shown in black in the areas shown by 1103, 1104, 1105) inside and that sandwich the rails.
Of the area shown by 105, the T-shaped part attached to the tower base 123 and sandwiching the rail)
It can move in the Z-axis direction (perpendicular to the paper surface). The image intensifier 124 and the SFD unit 125 are
One is connected to the tower base 123, and the other is arranged on a rail (black portion in the region shown in 1106) in the frame 122, and two tires sandwiching the rail (in the region shown in 1106). Attached to the image intensifier 124 and the SFD unit 125,
By the T-shaped portion sandwiching the rail), the lower side of the top plate 121 can be moved together with the tower base 123 in the Z-axis direction (direction perpendicular to the paper surface).

Since the frame portion 120 has such a structure, in order to remove the frame 122, first, the top plate 121 attached to the upper portion of the frame 122 is removed, and then the image intensifier 124 and the S.
The FD part 125 is removed, and the tower base 12 is further removed.
3 must be removed. That is, frame 1
Dismantling with removal of 22 is characterized by increasing the number of components dismantled.

FIG. 12 is a table showing such disassembly units. The "disassembly method that requires removal of the frame" shown in FIG. 12A is the height dimension when carrying in the X-ray fluoroscopic imaging apparatus. Since A and the width B (FIG. 13) are large, it represents a disassembly unit when the tower unit 110 and the frame 122 are removed.

As described above, the tower section 110, the frame section 120, and the tilting base section 130 (disassembly unit 1) are disassembled, and the tower section 110 is further divided into the tube 111 (disassembly unit 7) and the collimator 112 (disassembly unit). Unit 8), Tower 1

1 (disassembly unit 4), frame 122 (disassembly unit 2), S
The FD unit 125 (disassembly unit 5), the tower base 123 (disassembly unit 3), and the image intensifier 124 (disassembly unit 6) require disassembly. Conveying device utilizing the above characteristics From the above to the above, it is the tower portion in the height direction and the frame portion in the width direction that the X-ray fluoroscopic apparatus interferes with the carry-in entrance, Interference in the vertical direction
To cope with the problem by removing the easy-to-remove tower part, interference in the width direction can be reduced if the width dimension can be kept below B without removing the frame, and the number of disassembly can be reduced and interference in the width direction can be avoided. I knew I could do it.
