Abstract

PURPOSE:To set speedily a detector in an optional visual field in a labor-saving way without rotating a body to be detected by providing a detector support mechanism which is rotatable on a horizontal surface. CONSTITUTION:A detector support ring 12 is provided with a detector support arm 2 and the detector 2. This detector support ring 12 is supported on the detector suppot arm 2 by a rotating shaft 13, and the detector support arm 2 and detector 3 rotate in one body around the rotating shaft 13 as shown by an arrow 14. Further, the detector 3 is supported while fitted in the detector support ring 12 to obtain a slide structure which is ratatable on the horizontal surface as shown by an arrow 15 in internal contact with the detector support ring 12. The detector 3 and detector support ring 12 are held fixedly at specific positions by a fixing brake.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a scintillation camera device, and particularly to a scintillation camera detector for detecting a subject (such as a patient).
The present invention relates to a technology that is effective when applied to field of view setting technology.

Background art Figures 1 (A), (B), (C), and Figure 2 (A),
(B) gi, are diagrams for explaining the problems of the conventional scintillation camera device, in which Fig. 1 (A) is its front view, Fig. 1 (B) is its side view, and Fig. 1 (C) is its plan view, Fig. 2(A).

(B) is a diagram for explaining the operation. 'In the conventional scintillation camera device, Fig. 1 (A), (B),
As shown in (C), the detector 3 for detecting a radiation image does not have the function of rotating back and forth with respect to a horizontal plane. That is, the detector 3 is supported by a detector support arm 2 attached to a detector stand l, and its movement includes left and right rotational movement about an axis parallel to the horizontal plane4. Move up and down 5. Only horizontal movement 6 is possible.

In this case, in an apparatus in which the effective field of view of the detector 3 is rectangular, as shown in FIG. , as shown in FIG. 2(B), even if a field of view 1o including both arms 9 of the subject 8 can be secured, the field of view 10 in the body axis direction of the subject 8 is limited to a single imaging of, for example, both legs and liver. There is not enough to secure it. Therefore, conventionally, in order to secure a field of view up to both arms 9 of the subject 8 and a field of view in the body axis direction, it is necessary to image the subject 11 with the subject 8 rotated 90 degrees in the horizontal plane with respect to the detector 3. Was.

In this way, conventional scintillation camera devices
Since the subject 8 must be moved, the subject 8 weighing more than 2.00 kg including the weight of the bed 7 and the detector 3 must be moved.
There was a problem in that it required effort and effort to adjust the relative position of the vehicle.

SUMMARY OF THE INVENTION An object of the present invention is to provide a scintillation camera device that can improve imaging efficiency by eliminating labor and effort such as moving the subject and adjusting its position relative to the detector.

The above and other objects and novel features of the present invention will become apparent from the present specification, the description of Book a, and the accompanying drawings.

Toyoyo The configuration of the present invention will be explained below along with examples. j' Figures 3 (A), (B), and (C) are diagrams for explaining one embodiment of the scintillation camera device of the present invention, where (A) is a front view thereof, and (CB) is a front view thereof. Its side view, (C
) is its plan view.

In addition, in Fig. 3 (A), (B) t (c), the first
Components having the same functions as those in FIGS. (A), (B), and (c) are given the same reference numerals.

In this embodiment, as shown in FIGS. 3A, 3B, and 3C, the detector stand 1 shown in FIG. In a scintillation camera device comprising a detector support arm 2, a detector 3, etc., a detector support ring 12 is provided between the detector support arm 2 and the detector 8.

As shown in FIG. 3(B), the detector support ring 12 is supported by a rotating shaft 13 on the detector support arm 2-, and the detector support arm 2 and the detector 3 are integrated. It is configured to rotate in the direction of an arrow 14 about a rotating shaft 13. The detector 3 is fitted into and supported by the detector support ring 12, and has a sliding structure that allows it to smoothly rotate on a horizontal plane as shown by an arrow 15 while being inscribed in the detection amount support ring 12. The detector 3 and the detector support ring 12 are fixedly held at a predetermined position by a fixing brake (not shown).

As explained above, according to the new technical means disclosed in this application, by providing a detector support mechanism that is rotatable on a horizontal plane, the optimum field of view can be quickly and labor-savingly achieved without rotating the integrated object. The detector can be set to According to the inventor's experiments, the imaging time of the scintillation camera device of this embodiment is longer than that of the conventional one.
We were able to reduce the time per person by approximately 20%.

In addition, by not moving the subject around the device,
The subject's sense of anxiety can be reduced.

Although the present invention has been specifically explained above based on Examples, the present invention is not limited to the Examples.

Of course, various changes can be made without departing from the gist of the invention.
