Description

[Detailed description of the invention] (a) Industrial application field The present invention is used in the field of X-ray fluoroscopic tables and X-ray fluoroscopic imaging.

The present invention relates to holding an image intensifier (II) for lateral fluoroscopy in a two-way X-ray fluoroscopic photographing apparatus capable of performing fluoroscopy and imaging from the front direction and the lateral direction, that is, from two directions on the front side.

(B) Prior art The lateral fluoroscopic II of the conventional two-way X-ray fluoroscopic imaging device is either fixedly attached to the fluoroscopic imaging table or supported by a holder, and in either case, it is not connected to the fluoroscopic imaging table. It is held so that it can move easily. Therefore, an image is displayed on the TV monitor regardless of the patient's or subject's body position, such as standing, diagonal, or horizontal position. In other words, it is necessary to observe an image in a direction different from the actual direction when the patient is viewed from the side, and the image is interpreted in accordance with the dislocation angle of the imaging table, making diagnosis difficult.

(c) Purpose The purpose of this invention is to hold the lateral fluoroscopy II so that it can rotate relative to the fluoroscopy table, thereby making it possible to change the patient's position by raising and lowering the fluoroscopic table.
To provide a two-way X-ray fluoroscopic imaging device that allows observation on a monitor and allows observation of the flow direction of a contrast medium in the same manner as the actual direction.

(d) Configuration The above object is to provide a two-way X-ray fluoroscopy system equipped with a tiltable fluoroscopic imaging table and a lateral fluoroscopy system having an image intensifier held by a ceiling suspender. The image intensifier is connected to a fluoroscopic photographing table by means of a connecting device that slidably and rotatably holds the image intensifier via its outer frame circumferential surface, and when the fluoroscopic photographing table is raised and lowered, the image intensifier is By preventing the intensifier ear from rotating relative to the floor,
achieved.

(E) Embodiments A preferred embodiment of the present invention will be explained based on the drawings.

FIG. 1 is a front view showing the embodiment, and FIG. 2 is a side view thereof. FIG. 3 is an enlarged front view of the main parts, and FIG. 4 is a side view thereof.

In the drawings, 10 is a front perspective device;
10a is an X-ray tube, 10b is a collimator, 10c is a column, and 10d is II. On the other hand, 11 is a device for lateral fluoroscopy, 11a is an X-ray tube, 11b is a collimator, 11c is a ceiling suspender, 11d is II for lateral fluoroscopy, and 11e is its outer frame. Also,
12 is a photographing stand. 13 is a connecting fitting according to the present invention.

First, in Figures 1 and 2, for lateral perspective
II 11d is held by a ceiling suspender 11c on one side, and connected to the fluoroscopic photographing table 12 by a connecting fitting 13e on the other side. At this time, for lateral fluoroscopy
Each device is arranged and connected so that the line (beam center) connecting the center of II 11d and the X-ray focal point for lateral fluoroscopic imaging is perpendicular to the beam center in the forward direction, and when the fluoroscopic imaging table 12 is raised and lowered, The side view II 11d is supported so as not to rotate with respect to the floor surface, and is configured to slide and rotate at the connecting fitting 13.

In FIGS. 3 and 4, the connecting fitting or means 13
is shown in detail. 13a is I. for lateral perspective.
A mounting ring with a concave cross section fixed to the outer frame circumferential surface of I. 13b is a connecting frame edge that can slide along the concave portion, 13c is an extension support thereof, 13d is fixed to the side of the photographing table 12, This is a metal fitting for attaching and fixing the extension support part 13c. In this way, the lateral fluoroscopic II 11d is connected to the fluoroscopic photographing table 12 via the mounting ring 13a having a concave groove and the connecting frame edge 13b, and further by the metal fitting 13d. At this time, the beam centers in both the forward and side directions are perpendicular to each other, and this initial relative position does not change even if the fluoroscopic imaging table 12 is raised or lowered. And II1 for lateral fluoroscopy
1d remains supported by the ceiling suspender 11c and rotates relative to the fluoroscopic imaging stand 12 between the attachment ring 13a and the connecting frame edge 13b.

(F) Effects With this invention, changes in the patient's body position as the fluoroscopic imaging table is raised and lowered can be immediately observed on the TV monitor, and an image can be observed in the same direction as the actual direction of the patient when viewed from the side. This makes diagnosis easy, and the flow direction of the contrast medium is the same as the actual direction.
This has the advantage that even slight changes, such as when tilted or raised slightly, are easy to understand and can be quickly adapted to X-ray conditions.
