Description
Technical Field
The utility model belongs to the technical field of medical images, and particularly relates to an X-ray auxiliary photographing device for knee joints.
Background
Knee pain is a common symptom that can be caused by a variety of causes, such as knee arthritis, knee injury, ligament or tendon injury, and the like. X-ray is a commonly used medical imaging technique for observing and assessing bone structures, such as whether there is arthritis, bone fracture, osteoporosis, etc. By observing the X-ray images, a physician can diagnose some obvious skeletal abnormalities, helping to determine the cause of pain.
In knee joint X-ray examination, the procedure for performing the conventional alignment and lateral alignment is as follows:
Knee joint alignment: the patient lies on his back on the bed with the detected leg straightened and the toe slightly pronated. The X-ray enters vertically and aligns with the lower edge of the patella.
Knee joint lateral position: the patient's leg to be tested is held against the couch and the knee is bent at an angle of about 135 °. The X-ray enters vertically and aligns with the midpoint of the line between the inferior border of the patella and the popliteal fossa.
In the obtained high-quality knee joint X-ray image, the bone trabecula on the image is clear and visible, the soft tissue structure is clear in level, and the joint gap is displayed at the central position of the image. These sharp images may help the physician to better diagnose and evaluate knee joint structure and lesions. However, the knee joint images taken by the patient lying on the back on the photographing bed are all still images, and the condition of the joint in motion cannot be displayed by one-time imaging.
DDR (DIGITAL DYNAMIC Radiography) is an abbreviation for digital dynamic photography, also known as digital dynamic photography. It is an advanced medical imaging technique that can be used to dynamically view the knee joint in real time, including bending and straightening. In this process, the photographing apparatus will record the dynamic movement of the knee joint in a high-speed continuous photographing manner, and can provide more information about the knee joint function and lesions.
The optimal shooting mode is to enable the patient to stand on one leg, and the other leg is lifted horizontally to bend and straighten. However, it is difficult for the patient to maintain the posture in which one leg stands and the other leg moves, and the body may shake during dynamic photographing, resulting in blurring of an image. If the family members help to fix the patient, the family members are caused to passively receive unnecessary radiation doses.
Therefore, an X-ray auxiliary photographing device for knee joint is urgently needed to assist the patient to fix one limb, and the other knee joint is placed in a motion state, so as to ensure good image quality, and provide important image data for later diagnosis and treatment.
