Description

  The present invention relates to a fluoroscopic imaging table.

When imaging a subject's lower limb, ankle, or toe lesion using an X-ray fluoroscopic imaging table, long imaging may be performed with the weight applied, that is, in a standing position, for example, by a slot scanning method or the like. Many. Therefore, the X-ray fluoroscopic imaging table 1 is configured such that, for example, as shown in FIG. 5, a step 4 for supporting the subject 3 is attached to the foot side of the top board 2 when performing standing imaging. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 11-347028

  For example, when photographing an ankle and a toe by using a long scan such as a slot scan method using an X-ray fluoroscopic imaging table, the X-ray tube 5 irradiates the X-ray tube 5 as shown in FIG. A part of the collimated X-ray bundle 8 is blocked by the step metal part 4A of the step 4 attached to the top 2 of the X-ray fluoroscopic table 1, and is located on the back of the top 2, for example, a flat panel X-ray Since it cannot enter into the X-ray light-receiving part 7 comprised by a detector etc., the imaging | photography impossible site | part 9 generate | occur | produced in the lower limb of the subject 3, and it has interfered with the diagnosis. The present invention is intended to solve this problem.

In order to achieve the above-mentioned object, the invention according to claim 1 is a step that is attached to the top board and has a metal part , and has a lower X absorption rate than the step and does not interfere with the diagnosis. An X-ray fluoroscopic imaging table having a platform made of a material having a low X-ray absorption rate and a durability lower than that of metal , characterized in that it is configured to be rotatable so that both upper and lower surfaces can be made a platform. X-ray fluoroscopic imaging table.

  In order to achieve the above object, the invention according to claim 2 is the X-ray fluoroscopic imaging stand according to claim 1, wherein the material is carbon, vinyl chloride, or resin.

  According to the present invention, an additional step having a structure in which a material having low X-ray absorption is pasted on a wooden board is attached on the step that is attached to the top board, thereby eliminating an unphotographable part even when photographing ankles and toes. be able to. In addition, since the additional platform is configured to be detachable from the metal platform of the platform, it can be mechanically removed at the same time by removing the X-ray absorption and using an ordinary platform except for ankles and toes. It can compensate for the low durability of the additional platform due to the low strength material.

  An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, when photographing the ankle and toe of a standing subject 3 using the fluoroscopic imaging table 1, an operator (not shown) places the subject 3 on the top 2. Prior to this, the additional platform 10 shown in FIG. 2 is mounted on the platform metal portion 4A of the platform 4 mounted on the foot side of the top board 2. 2A is a side view of the additional platform 10, and FIG. 2B is a front view.

  The additional step board 10 is a low-absorption step board which is a rectangular board having a low X-ray absorption rate, which is made of, for example, foamed polyethylene on the upper surface of a rectangular wooden mounting plate 10B having the same width and thickness as the step metal part 4A. 10A is bonded, and furthermore, L-shaped fixing brackets 10C are attached to both ends of the front surface of the wooden mounting plate 10B. The fixing bracket 10 </ b> C is provided with a screw hole (not shown) for screwing a fixing screw 10 </ b> D so that the operator can attach the additional step 10 on the step metal part 4 </ b> A.

  Then, as shown in FIG. 1, when the subject 3 stands on the low absorption tread 10A of the additional step 10 attached on the step metal part 4A, the X-ray absorption rate is between the sole and the step metal part 4A. Therefore, the occurrence of a non-imagingable portion as described in the section “Problems to be solved by the invention” can be eliminated.

  Further, the low-absorption tread board 10A is usually made of a material having low X-ray absorption but low mechanical strength, so that it has a drawback of low durability. Therefore, when photographing other than ankles and toes, the operator needs The fixing screw 10D is loosened so that the additional step board 10 can be removed from the step metal part 4A.

  In FIG. 1, reference numeral 7 denotes an X-ray light receiving unit which is arranged on the back surface of the top plate 2 and is constituted by, for example, a flat panel X-ray detector.

  As shown in FIG. 3 (a), the X-ray absorption rate of the step metal part 11A of the step 11 attached to the top plate 2 of the X-ray fluoroscopic table 1 is made of, for example, foamed polyethylene. The same effect as described above can also be obtained by bonding the low absorption tread 11B which is a low rectangular plate. Then, as shown by an arrow A in FIG. 3B, the step metal part 11A is rotated to constitute the step 11 so that the low absorption step board 11B can be arranged on the lower surface of the step metal part 11A. The problem of durability of the low absorption tread 11B can be reduced by standing a subject (not shown) on the step metal part 11A at the time of photographing.

  The present invention relates to a fluoroscopic imaging table.

It is a figure for demonstrating the Example of this invention. It is a figure which shows the structural example of the additional platform of this invention. It is a figure for demonstrating another Example of this invention. It is a figure for demonstrating the imaging | photography using the conventional tread. It is a figure for demonstrating the conventional X-ray fluoroscopic imaging stand.
