Breathing patterns in hand back-and-forth photography

Breathing patterns for back and front photography are as follows:

1. Photographing position: The examinee sits on one side of the photographic bed, with wrist joints and fingers straight, palms down, fingers straight and naturally separated, and flat on the IR. The third metacarpal bone is placed in the center of IR, and the upper edge of IR includes phalangeal soft tissue and the lower edge includes wrist joint. When taking pictures with both hands at the same time, the examinee faces the photographic bed, his arms are stretched forward, and the chapter face is placed symmetrically on IR.

2. The midline is aligned with the third metacarpal bone for vertical injection. If both hands are ingested at the same time, the center line is injected vertically through the midpoint of the third metacarpal line of both hands.

3. The image shows that the metacarpophalangeal bones of 2-5 sides are in an upright position, and the metacarpophalangeal bones of the thumb are in an inclined position. Bone trabecular display is clear and soft tissue display is good.
