ABSTRACT:
Mounting pins having a head portion are provided on the detector member of a nuclear medicine diagnostic apparatus while a coupling mechanism associated with a collimator is registrable with the mounting pin. The coupling mechanism includes an entrance aperture sized and configured to accept the head portion therein and claw members adjacent to the aperture for engagement with the head portion. The mounting pin and coupling mechanism together cooperate to permit the head portion to be accepted in the entrance aperture when the collimator member is in a dismounted position and to permit the claw member to be moved into engagement with the head portion in response to relative movement between the collimator and detector members in a mounting direction between the dismounted position and a mounted position. A biasing mechanism is preferably provided so as to forcibly urge the claw member against the head portion to securely retain the claw member thereagainst. Cam surfaces are also preferably provided on the forward end portion of the claw member such that upon relative movement between the collimator and radiation detector members, the cam surfaces responsively effect displacement of the biasing mechanism into a retracted position so as to aid in mounting of the collimator.
