Description

The Auxillary Equipment for Multi Angles X-ray Table Integral Type in Patella Radiographs < RTI ID = 0.0 >

The present invention relates to an auxiliary device for a knee bone X-ray imaging, which is mounted on an X-ray imaging apparatus having a table on which a person to be imaged can be laid. More particularly, The present invention relates to an assistant device capable of obtaining an axial view X-ray image of an accurate and ideal knee bone by easily adjusting an X-ray shooting angle and stably maintaining a shooting posture.

An X-ray imaging apparatus, which is one of medical diagnostic apparatuses, is an apparatus for irradiating X-rays to a specific region of a photographee and detecting the transmitted light and imaging it to detect abnormality of the bones, ligaments, etc. of the human body.

Generally, an X-ray photographing apparatus photographs an X-ray irradiating unit for irradiating X-rays and an imaging plate (IP) for detecting X-rays transmitted through the human body of the photographee, .

1 and 2, the X-ray imaging apparatus mainly includes an X-ray irradiating section 30, a mounting section 14 for mounting an image plate, and a table 10 or image And a stand 60 for mounting the plate so that the subject to be photographed lies or sits on the table 10 so as to photograph a part to be inspected or stand in front of a separate stand 60 installed at a proper position in the photographing room.

Recently, a structure capable of freely adjusting the irradiation angle and position of the X-ray irradiating unit 30 in the 3 (x, y, z) axis direction in order to photograph various body parts in a comfortable posture and increase the convenience and efficiency of the photographing operation Various proposals have been made.

On the other hand, the axial radiographic image of the knee bone using such an X-ray imaging apparatus is obtained by bending the knee bending angle of the subject 45 degrees and adjusting the X-ray irradiation angle to 60 degrees from the vertical plane, and then the central incidence point of the X- And irradiated toward the space between the protrusions. At this time, in order to ensure reproducibility, repeatability and convenience, most of them use an auxiliary viewer (Axial viewer).

That is, as shown in FIG. 3, an axial viewer, which is an auxiliary device for obtaining X-ray images of an axial view of a knee bone, is placed at the end of the table 10 of the X- A calf rest 2 having a knee angle of 45 degrees with respect to the table 10 so that the image plate (or film) can be placed on the shank, (4).

In recent years, however, due to the westernization of the eating habits and changes in lifestyle due to the improvement of living standards, the body size of the knee has been increased to 45, It is difficult not only to obtain a medical diagnosis image but also to take a re-imaging if an accurate diagnosis can not be made by a single photographing, thereby causing unnecessary radiation exposure.

For example, as shown in FIG. 4, (a), the knee flexion angle and the X-ray incidence angle are appropriately made, and the knee bony bottom surface is well overlapped and the knee femoral joint is well observed.

However, when the angle of bending of the knee is large and the angle of incidence of the X-ray is small at the vertical plane due to the specific type of the photographer, the tibial tuberosity is projected between the intercondylar sulcus as shown in (b) and (c) Or the floor of the knee bone is not overlapped, so that the knee femoral joint can be covered.

On the contrary, if the knee flexion angle is small and the incident angle of the X-ray is too large on the vertical plane, Lt; / RTI >

In the conventional 6-way system in which the table 10 of the X-ray imaging apparatus moves freely in three axial directions, the position of the axial viewer is reset according to the position, direction, and height of the X- There is a limit to the inconvenience and inconvenience of moving and storing.
