【発明の詳細な説明】
［発明の目的］
（産業上の利用分野）
本発明は、架台ドームにより形成される撮影空間に被検
体を収容させる天板を構成したＣＴ用の架台装置に関し
、特に撮影空間の照明技術に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a mount device for CT that has a top plate for accommodating a subject in an imaging space formed by a mount dome, and particularly relates to Concerning lighting technology for shooting spaces.
（従来の技術）
ＣＴ用の架台装置は、Ｘ線や磁気共鳴現象を用いて被検
体を断層ｍ影する場合に使用される。(Prior Art) A CT mount device is used when taking a tomographic image of a subject using X-rays or magnetic resonance phenomena.
このＣＴ用の架台装置が磁気共鳴現象を用いる磁気共鳴
イメージング装置（以下ＭＲＩ装置という）に適用され
た場合、特に静磁場発生用に超電導磁石を使用するＭＲ
Ｉ装置に適用された場合には、静磁場発生用の磁石の長
さが長く、またそれにともない架台ドームにより形成さ
れる撮影空間が長くて狭いものとなる。When this CT mount device is applied to a magnetic resonance imaging device (hereinafter referred to as an MRI device) that uses magnetic resonance phenomena, it is particularly useful for MR that uses a superconducting magnet to generate a static magnetic field.
When applied to an I-device, the length of the magnet for generating the static magnetic field is long, and the imaging space formed by the gantry dome is therefore long and narrow.
そのため、先に、架台ドームにより形成される撮影空間
を照明し、被検者に不安感を与えることがないようにす
ることが提案され、この提案が実用化されている。Therefore, it was previously proposed to illuminate the imaging space formed by the gantry dome so as not to make the subject feel uneasy, and this proposal has been put into practical use.
（発明が解決しようとする問題点）
しかしながら、従来提案された撮影空間の照明方法は、
ＭＲｒ装置が設置された検査室の設備としての光源を利
用するもので、その光源からの光を架台ドーム内へ導く
ことにより撮影空間を問接的に照明するものであった。(Problems to be Solved by the Invention) However, conventionally proposed lighting methods for photographing spaces:
This system utilizes a light source as equipment in the examination room where the MRr device is installed, and illuminates the imaging space indirectly by guiding the light from the light source into the dome of the mount.
そのため、大根上の被検体により光源からの光が遮ぎら
れたりして十分な照明効果を得ることができない。Therefore, the light from the light source is blocked by the subject on the radish, making it impossible to obtain a sufficient illumination effect.
従って、従来の場合においては、被検体となる患者に対
し、架台ドーム内の撮影空間は暗いという印象を与え、
ひいては患者に不安感を持たせることになるという不具
合があった。Therefore, in the conventional case, the imaging space inside the gantry dome gives the impression to the patient being examined that it is dark.
Furthermore, there was a problem in that the patient was made to feel anxious.
本発明の目的は、架台ドームにより形成されるＩ！影中
空間この９閂内部において明るいと感じさせることがで
きるＣＴ用の架台装置を提供することにある。The object of the invention is to provide an I! An object of the present invention is to provide a CT mount device that can make the interior of the nine bars feel bright in the shadow space.
［発明の構成］
（問題点を解決するための手段）
本発明は、上記の目的を達成するため、内部が石彫空間
となる架台ドームと、この架台ドームの長手方向に沿っ
て相対移動させて被検体を前記ｍ影空間まで外部から搬
入する天板とを備えた架台装置であって、前記大板の長
手方向の側縁部に光源を設けたことを要旨とする。[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention includes a pedestal dome whose interior is a stone carving space, and a pedestal dome that is moved relative to each other along the longitudinal direction of the pedestal dome. The gist of the present invention is to provide a gantry device including a top plate for transporting a subject from the outside into the m-shadow space, and a light source is provided at a longitudinal side edge of the large plate.
（作用）
本発明による０丁用の架台装置では、大板の長手方向の
＠縁部に設けた光源から発せられる光によって、架台ド
ーム内の撮影空間を照明する。(Function) In the 0-frame mount device according to the present invention, the photographing space inside the mount dome is illuminated by light emitted from a light source provided at the edge in the longitudinal direction of the large plate.
そのため、光源からの光は架台ドーム内において、被検
体に遮ぎられることなく被検体の下側から上方へ放散さ
れる。Therefore, the light from the light source is radiated upward from below the subject within the gantry dome without being blocked by the subject.
従って、架台ドームの内面により光源からの光が多方位
へ反射されて、架台ドーム内が明るくなり、また、光源
からの直接光が被検体となる＠者の目に入射されること
がない。Therefore, the light from the light source is reflected in many directions by the inner surface of the gantry dome, making the inside of the gantry dome brighter, and direct light from the light source is not incident on the eyes of the subject.

とを備えでいる。As shown in FIG. 1, a CT mount device according to an embodiment of the present invention is suitable for use in such an MHI apparatus, and as shown in FIG. A top plate 8 is moved 1 inch relative to the longitudinal direction of the dome 3 to carry the subject A from the outside into the gantry dome 3 which becomes the imaging space.
I am prepared for this.

方へ放散される。The top plate 8 is provided with a side edge in the longitudinal direction, especially for the subject A.
Light sources 9 are provided at the left and right edges of the patient's head position (see Fig. 2), so that the light from the light sources 9 enters the dome 3 and is not blocked by the patient A. It is emitted upward from the bottom of the specimen 1.
従って、架台ドーム３の内面により光源９からの光は多
方位へ反射され、架台ドーム３内が均一に明るくなる。Therefore, the light from the light source 9 is reflected in many directions by the inner surface of the gantry dome 3, and the inside of the gantry dome 3 becomes uniformly bright.
