The T-Lock Stand was designed specifically allow the calibration marker to be set at the height of the greater trochanter, and yet still appear within the narrow field of the radiograph. By first adjusting the MCM horizontal arm to the desired height outside of the field, and then locking it in place, the entire stand can be moved to the inner thigh area where the radiograph can be taken with confidence.The marker height locks in place and will not move if bumped or jarred.
