Description

Treatment Guide System for C-Arm Radiography Apparatus The present invention relates to medical equipment, and more specifically, to a treatment guide system for a C-cancer radiation imaging device. Figure 1 is a configuration diagram of a C-arm radiation imaging device. This is configured to include a table (11), a C-arm frame (12), an X-ray irradiation unit (13), and a detection unit (14). The table (11) supports the subject (P) (a patient taking a position for treatment). The C-arm frame (12) is rotatably installed on one side of the table (11). The X-ray irradiation unit (13) is coupled to one end of the C-arm frame (12) to irradiate X-rays (X) onto the target (P). The detector (14) is coupled to the other end of the C-arm frame (12) to detect X-rays passing through the target (P). A C-cancer radiation imaging device is a device that obtains medical images by means of an X-ray irradiation unit (13) and a detection unit (14) and uses them as an auxiliary treatment, and is currently widely used in hospitals. In the case of nerve treatment for the lumbar or cervical spine, medication is injected into the inflamed nerve area. By taking images with a C-arm radiography device before and after the insertion of the needle into the affected area, the needle and the interior of the affected area are displayed together in the X-ray image, allowing verification of whether the needle has been inserted in the correct position. For example, in the case of injection treatment for nerve treatment of the cervical spine, the injection needle must enter through the entry point (a) and reach the target point (b) accurately; to achieve this, the injection needle must be inserted through the accurate insertion line (B). (Figs. 2 to 4) Figure 5 is an X-ray image showing the entry point (a) and the target point (b) together. This is a case where the entry point (a), the target point (b), and the center of the X-ray irradiation unit (13) do not form a straight line, so the entry point (a) and the target point (b) are shown as being in different positions in the X-ray image (plane). If the entry point (a), the target point (b), and the center of the X-ray irradiation unit (13) are aligned in a straight line, the entry point (a) and the target point (b) will be displayed at the same location in the X-ray image (plane). In this way, the doctor must place the needle at the entry point (a) and insert it at a specific angle to reach the target point (b). However, during the insertion of the needle, if the angle of the needle is slightly misaligned, it will deviate from the insertion line (B) (dotted line in the drawing), so the needle must be inserted while continuously checking the insertion path of the needle (position of the tip of the needle) through repeated X-ray imaging. That is, while holding the syringe in his hand, the doctor inserts the needle through the entry point (a) and repeats X-ray imaging several times to check whether the needle is passing through the insertion line (B) and whether it has reached the target point (b). As a result, there is a problem of excessive exposure to X-rays for both patients and doctors. Patients are exposed to X-rays only during a single treatment, but doctors, in particular, must continuously perform such treatments on multiple patients, so exposure to and accumulation of a significant amount of radiation cannot be avoided. Korean Registered Patent No. 10-2668614 (Guide Light Assembly for C-ARM Radiation Imaging Device) is intended to resolve the above problem by installing a guide light assembly (50) in a C-arm radiation imaging device and irradiating light from the guide light assembly (50) to display multiple reference points in the patient's treatment area (waist, neck, etc.) so that medical staff can visually confirm them (Figs. 6 to 9). Specifically, the guide light assembly irradiates multiple laser beams in the X-axis and Y-axis directions to display grid lines, wherein the intersection of the grid lines serves as the aforementioned reference point. However, in injection therapy, this can only mark the entry point (a) of the injection needle on the affected area of the subject (patient), and since there is no guide means regarding the insertion path (angle) of the injection, it cannot guide the accurate insertion line (B) and target point (b). In addition, since the laser beam is only displayed on the subject's skin and not on the X-ray image, the relationship between the point displayed on the skin and a specific point on the X-ray image cannot be determined. Therefore, the problem of requiring multiple X-rays during treatment ultimately remains. The drawing symbols of the above prior art are limited only to the description of the said prior art. Figure 1 is a configuration diagram of a C-arm radiation imaging device. Figures 2 to 4 are conceptual diagrams regarding the injection treatment process for the cervical spine.
