Meanwhile, a radiographic apparatus such as a tube T may be used to irradiate radiation such as X-ray with the radiographic auxiliary device 1. In particular, the radiographic assistance device 1 of the present invention can adjust the height so that the radiation irradiated upward from the tube T located below the patient is irradiated in the tangential direction of the patient's patella.

The support 11 may have a triangular column shape. The support 11 has a flat lower surface 111 in contact with the floor and a region of the upper surface 113 composed of two inclined surfaces connected to the lower surface 111 to form an interior angle of a preset range, thereby forming an inner angle of the patient's lower limb. I can support it.

In detail, the support 11 may be provided in a form in which the shape of a triangular pillar is modified. The longitudinal section of the support 11 may have a shape in which the bottom surface 111 contacts the bottom and the top surface is raised. The support 11 may have an interior angle of 100 degrees to 140 degrees formed by one region. Preferably, the support 11 may have an inner angle of 115 degrees to 125 degrees formed by one region. More preferably, the support 11 may have an inner angle of 120 degrees formed by one region. In this case, the femoral patella joint of the lower limb supported by the support 11 may form 120 degrees due to the angle formed by the thigh 9 and the lower leg 8 in contact with the support 11.

Meanwhile, as shown in FIG. 1, in preparation for contact of the patient's hamstrings, the protrusion area of the upper surface 113 formed by the inner corner of the support 11 may be rounded. Accordingly, when the patient uses the support 11, the pressure is concentrated at a local point to prevent pain applied to the patient.
