Key points of hand oblique photography

The main points of hand oblique photography are as follows:

1, the patient sits up straight, the upper limb naturally hangs to one side, and the palm of his hand clings to the X-ray detector upward.

2. The doctor adjusts the position of the patient's arm so that it is as close to the detector as possible to avoid blurring the hand image.

3. Ask the patient to put his palm up, with his wrist and palm close to the metal sheet near the plain film, and his fingers naturally extend.

4. After placing the X-ray detector and hand correctly, the doctor sets the exposure parameters on the imager and tells the patient not to move his hand.

5. For the follow-up image processing and diagnosis, doctors need to refer to the anteroposterior images, observe the anatomical structure and characteristics of bones, and judge whether there are changes such as fractures, joint dislocations and soft tissue swelling.

Ortho-oblique hand photography is an imaging method and a medical imaging technology, which is used to examine the diseases of metacarpal bones, joints and soft tissues, and is often used to diagnose hand fractures, dislocations, osteoporosis, arthritis and other diseases. Doctors should carefully observe the shape, structure and changes of hand bones, joints and soft tissues when evaluating the examination results, and make a diagnosis in combination with clinical symptoms.

Matters needing attention in hand oblique photography

1. Photographing position: When taking oblique hand radiographs, the patient should stand in front of the camera and put his hand on the examination table to ensure that his hand forms an angle of 15 degrees with the filming plane.

2. Select the camera equipment: oblique hand radiographs need to be shot by a combination of X-ray machine and digital flat panel detector, and the quality of the equipment needs to be guaranteed.

3. Avoid improper hand movements: explain to the patient before shooting, keep your hands steady and don't move, so as not to affect the photo quality. The patient can be given several actions, such as clenching his fist, raising his wrist and keeping his hand posture fixed.

4. Protective measures: X-ray protective articles such as gel coat or lead coat should be brought to the patient before shooting, and the radiation dose of the patient should be paid attention to to reduce its impact on the body.

5. Keep the picture clear: Metal objects on the skin of the patient's hand, such as rings and watches, will become the influencing factors of the picture. Before taking pictures, patients should be reminded to empty the above items to ensure a clear picture.
