Abstract

PROBLEM TO BE SOLVED: To provide an ankle joint X-ray imaging aid capable of alleviating the pain caused by the posture of a subject during X-ray imaging and improving accurate positioning during imaging and reproducibility during reimaging. SOLUTION: A low base main body 1 is provided on a bed of an X-ray inspection apparatus, a footrest 6 on which a foot is placed on the upper surface of the base main body, an angle reference plate 3 for determining an ankle angle, and further, the foot. Cassette stands 4 and 5 into which the film cassette 10 can be inserted are provided on both the left and right sides of the stand. It is preferable that an angle reference plate mounting portion 2 having a groove is formed behind the footrest, the angle reference plate is triangular in shape, and can be slid to the left or right using the groove as a guide.

Description

Radiographic X-ray imaging performed in medical practice generally requires a burden on the subject, is painful, and requires a high degree of skill of the radiographer due to the complicated procedure.
By using the imaging aid of the present invention, it is possible to reduce the burden on the subject and to quickly and accurately shoot the distance joint portion without distortion, and to obtain a highly reproducible imaged image at the time of imaging for the final inspection.
In order to accurately depict the temporomandibular joint, it has an angle adjustment function so that the X-ray incident angle and the film surface are at an appropriate angle. In addition, the safety of the subject was improved, the strength of the auxiliary tool was improved, and the size and weight were reduced.

A combination of foamed polystyrene and an acrylic plate has been prototyped and published at the Radiological Society of Japan as an imaging aid for the distance joint (Antonsen 1 method).

1) Pain from shooting position.
The subject's body posture at the time of photographing is prone position, accompanied by pain and pain.
2) Precise positioning and difficulty in reproducibility during re-shooting.
The subject was photographed in the position of 1) above, and it was difficult to set the angle of the foot and the body position was static and the reproducibility was poor.
3) Distortion occurs when the joint surface is drawn.
Since the X-ray incident angle and the film surface are not appropriate angles, the joint surface is distorted.
4) Instability of the cassette table and insufficient strength of the photographing aid.
5) Hygiene management as a medical aid and instability of safety.

  In the sitting or supine position, the subject puts his / her foot on the footrest of the installed assisting device, attaches the sole to the angle reference plate installed in the back, and uses the reference centerline of the sole as a reference The posture is just to match the angle line. The cassette base has a function that can be positioned and fixed at a plurality of appropriate angles, and has a structure and material that is rigid and easy to manage hygiene.

1) Pain relief by subject's posture.
The subject becomes a sitting or supine position, and even a highly severe subject can be easily positioned and pain can be alleviated.
2) Accurate positioning and improved reproducibility during re-shooting.
The position becomes painless and the position and angle of the affected area can be set easily, so positioning is accurate, and the position is easily maintained and reproducibility is excellent.
3) Reduction of distortion of captured images.
Distortion of the photographed image is eliminated by setting the X-ray incident angle and the film surface to an appropriate angle.
The cassette base can be positioned and fixed at a set angle, and can be positioned at multiple angles as necessary, increasing the rigidity of the entire auxiliary tool.
4) Appropriate surface treatment is performed using materials that are considered for safety and hygiene management as medical aids.

It is a three-dimensional perspective view from the whole front part (subject side). It is the whole top view. The subject comes to the bottom of the figure. It is the use condition figure seen from the subject side.

Embodiments of the present invention will be described below.
1) Attach a footrest base 6 on which the subject's feet are placed in the center of the upper surface of the base body 1 having a low trapezoidal shape.
2) An angle reference plate mounting portion 2 having a groove type guide is fixed to the rear of the footrest 6 and an angle reference plate 3 having an angle of 30 degrees is inserted into the groove portion so that it can slide horizontally. It is also possible to turn the angle reference plate 3 upside down.
3) Place the cassettes 4 and 5 slightly on the left and right sides of the footrest 6. The cassette table can be turned around the central axis 9. The cassette base is positioned by a hole at one end and a positioning hole 8 provided in the base body so that the reference angle is 25 degrees, and is fixed by a fixing bolt 7. A plurality of positioning holes 8 are provided so that the angle can be changed.
5) The cassette bases 4 and 5 are open at the top and rear, and a guide surface is provided at the rear end so that the cassette film can be easily inserted from the rear. 6) The whole is rigid and safe and lightweight. Surface treatment using materials.
The present invention has the above configuration.
When using the present invention, place the present invention on the bed of an X-ray imaging apparatus, place the subject's feet on the footrest 6, and align the soles with the angle reference line 13. The film cassette 10 is inserted into one of the cassette tables 4 and 5 with respect to the X-ray incident direction 11 or 12.

    By using the present invention, an accurate image can be obtained quickly and safely regardless of the condition of the subject and the proficiency level of the imaging technician. Furthermore, it has excellent resilience during re-shooting.
