Claim:
1. A radiation camera system comprising: (a) radiation sensor/detector (RSD); (b) coded camera aperture mask (CAM); (c) CAM ID reader (CIR); (d) mask rotation motor (MRM); (e) rotation detection sensor (RDS); (f) radiation camera enclosure (RCE); and (g) computing control device (CCD); wherein: said RCE is configured to mechanically couple said RSD, said CAM, said MRM, said RDS, and said CCD; said CAM is configured to cover said RSD and collimate radiation external to said RCE that is presented to said RSD; said MRM is configured to rotate said CAM under direction of said CCD; said CAM further comprises coded identification indicia (CII); said CII encodes a unique CAM identification and aperture mask type being applied to said RSD via said CAM; said CIR is configured to read said CII and transmit said unique CAM identification said aperture mask type to said CCD; said CAM further comprises a plurality of rotation indicia (PRI) that identify the current rotation angle of said CAM; said plurality of rotation indicia (PRI) are configured to provide a clock with time intervals configured to detect the presence or absence of said CII when said CAM is rotated; said RDS is configured to detect said plurality of rotation indicia (PRI); said CCD is configured to capture detected radiation data from said RSD and transmit said detected radiation data via a digital communications medium (DCM) to a host computer system (HCS); said CCD is configured to receive rotation commands from said HCS via said DCM and activate said MRM in response to said rotation commands; and said CCD is configured to capture rotation data from said RDS and transmit said rotation data via said DCM to said HCS.
