In the case of (Computed Radiograph), the size and position of the affected area were calculated by measuring with a ruler on the developed photograph and calculating proportionally the value and the scale on the developed photograph.

るという問題があった。However, in X-ray photography for measuring the size and position of the affected area, so-called scale-type X-ray photography, it is troublesome to measure with a ruler on the developed photograph, and Particularly in the case of CR, since the scale is far from the affected area, it is difficult to accurately measure the size and position of the affected area, and the proportional calculation itself is complicated. Further, in X-ray photography for measuring the position of the affected area, that is, so-called mark-type X-ray photography, it is impossible to securely fix the subject to a metal pin, clip, or the like.
There is a problem that it is easy to shift during the measurement, and it is difficult to measure the accurate position of the affected area.

で、測定作業も非常に容易になる。According to the above construction, when the X-ray photography index piece formed by using the index as a scale is fixed to a portion (near the affected area) where the subject is to be photographed and the X-ray photography is performed, the scale itself is affected. The size and position of the affected area can be accurately measured because the scale itself is scaled up and down at the same rate as the photograph is scaled up and down.
Therefore, you can directly determine the size and position of the affected area,
Since it is not necessary to use a ruler or perform proportional calculation, the measurement work becomes very easy.

Unlike the case where it is simply placed on the surface of the subject, it does not shift during measurement, so accurate position measurement is possible. In particular, in CT scan type X-ray photography, if an index piece on the X-ray photography for which two points can be confirmed in the cross section and the distance between the two points continuously changes is used, a predetermined value can be obtained. The position of the index is obtained from the relationship between the set cross-sectional interval and the change in the distance between the two points in the two cross-sectional images, and the positional relationship between the index and the affected part is determined depending on which cross-section the affected part appears. Can be asked.

The index piece will be described in detail. FIG. 1 shows a first embodiment of the present invention , that is, an X-ray photography index piece used for scale-type X-ray photography. The index piece 1 has an X-ray absorbent ( The index 3 as a scale is printed by using a paint containing powder, and is attached to the surface of a subject such as a patient. 4 is a symbol of, for example, "R", which is also printed on the seal 2 using a paint containing an X-ray absorber. Although not shown, the surface of the seal 2 after forming the index 3 is covered with a resin layer.

A (lead) -based material is preferable, but not limited to this, an HgS (mercury sulfide) -based material or a BaSO 4 (barium sulfate) -based material may be used. Various paints such as urethane paints are available. The concentration of the X-ray absorber and the thickness of the paint should be such that they can be sufficiently discriminated on an X-ray photograph. For example, in the case of using lead as the X-ray absorber, a rating of "○" or higher in Table 1 The obtained thickness, that is, the thickness converted to the case of lead alone, is preferably 10 μm or more (No. 3 or later).

As a result, as shown in FIG. 3, the index 3 itself, which is a scale, is also projected in the immediate vicinity of the affected area 6. Also in the case of CR, as shown in FIG. 4, the index 3 itself, which is a scale, is scaled at the same rate according to the scaling of the photograph, so that the size and position of the affected area 6 can be accurately measured. is there. Therefore, the size and position of the affected area 6 can be directly obtained, and there is no need to use a ruler or to perform proportional calculation, so that the measurement work becomes very easy.

For example, in the case of emergency surgery, the incision position is closest to the affected area. The position can be set quickly and the size of the incision can be minimized. Therefore, the treatment can be performed promptly, and the pain and burden on the patient can be reduced, so that the therapeutic effect such as life saving effect can be significantly improved.

Since the fracture direction, size, etc. of the fracture site can be measured accurately, the dimensions of the plate, screw, and nut can be selected quickly and accurately, and as a result, the therapeutic effect can be greatly improved. In this case, if the sterilized index piece 1 is attached to the surface of the subject 5 near the affected area before wearing the cast, the healing state of the affected area can be observed by X-ray photography while wearing the cast. You can do it, which is convenient. Further, in the case of surgery or examination performed while observing with an X-ray camera or the like while using a catheter or an endoscope, if the index piece 1 that has been sterilized in advance is attached to the surface of the subject 5 near the affected area, the position and size of the affected area can be increased. Can be easily understood, and surgery and inspection can be performed accurately.

It is effective in preventing this. Further, when lead powder having biotoxicity is used as the X-ray absorber, it is effective in preventing it from touching the skin surface.

The index piece 11 is an X-ray on an adhesive sticker 12. The mark 13 is printed by using a paint containing an absorbent (powder) as a mark, and is attached to the surface of a subject such as a patient. Although not shown, the surface of the seal 12 after forming the index 13 is covered with a resin layer. Since the other construction is the same as that of the X-ray photography index piece used in the first embodiment, detailed description thereof will be omitted.

When a CT scan of the head is performed by fixing it to the part to be imaged (near the affected part), as shown in FIG. , B are projected, and in the photograph of the tomographic plane B, the intersections c and d of the index 13 and the tomographic plane B are projected. And, in the normal CT scan, the interval between the tomographic planes A, B, and C is 10
Since it is mm, the distance from the center point of the "x" mark of the index 13 to the tomographic plane A can be obtained by the following formula 10xab / (ab + cd) (1) as is clear from FIG. Therefore, the distance between points a and b is 1
Assuming that the distance between the points c and d is 0 mm and the distance between the points c and d is 25 mm, the distance from the center point of the “x” mark of the index 13 to the fault plane A is about 2.8 mm, and the fault plane C in FIG. Affected part 16
If so, it can be confirmed that the affected part 16 is located at a distance of about 17.2 mm from the center point of the “x” mark of the index 13.

According to this embodiment, unlike the case where a metal pin, clip, or the like is simply placed on the surface of the subject, the index 13 does not shift during measurement, so that the accurate position of the affected area 16 can be measured. is there. Further, since the index 13 is made of a paint having an appropriate thickness and containing an X-ray absorber of an appropriate concentration, it does not cause artifacts such as metal pins and clips.

効であるのは言うまでもない。When the CT scan is performed in this manner, the accurate position of the affected area can be easily measured, so that the radiation treatment for cancer or the like can be effectively performed. Further, even in brain surgery or the like, since it is only necessary to open the necessary minimum holes in the skull, the pain and burden on the patient can be reduced. Needless to say, it is also very effective for emergency surgery and emergency surgery.

Therefore, it is preferable to secure the thickness of, for example, 50 μm or more. However, the concentration of the X-ray absorber and the thickness of the paint are the same as those of the sample N shown in Table 1 of the first embodiment.
o. When it is 7 or more, an artifact is generated, which is not preferable.
