How to photograph the anterior and posterior positions of bilateral ankle joints at the same time

1, let the subjects lie flat on the X-ray machine with their feet straight and close together.

2. Adjust the position and angle of the X-ray machine to make it perpendicular to the bilateral ankles of the subject, and focus the X-ray beam between the metatarsal and calcaneus.

3. For unilateral cases, place the projection center point about 1 cm above the midpoint of the medial and lateral malleolus line; For bilateral cases, the center between two projection points is the projection center.

4. Ensure that the patient does not move, so as to avoid blurring or distortion of the image, and select appropriate examination parameters as needed.
