Which distance unit is included in the standard SID for tangential sesamoid radiographs?

Explanation:
The distance from the X-ray source to the image receptor (SID) for this tangential sesamoid projection is given in inches. The standard SID value used is 40 inches, which is the unit you’ll see in typical radiography guidelines and exposure charts for this projection. This ensures the beam geometry and magnification are appropriate for clearly imaging the sesamoid bones. If you convert, 40 inches is about 102 centimeters, but the conventional unit in this context is inches.
