Abstract
A radiation camera system and method incorporating a radiation sensor/detector (RSD) and automated operation of coded camera aperture masks (CAMs) is disclosed that may be advantageously applied to real-time tracking of radiological hot spots in crisis, maintenance, decontamination, and/or maintenance scenarios. The system/method integrates automated camera RSD positioning, CAM identification, and CAM rotation. The system incorporates computerized controls in conjunction with remotely controlled horizontal/vertical tilting motors to direct the RSD aperture position and view of the RSD. CAMs may be installed in the camera manually and are automatically identified by the system via the use of encoding magnets that are detected using a Hall-effect sensor. The CAMs may be rotated after installation in the camera by computer control to predefined positions such as “mask” and “anti-mask” to affect the desired degree of radiation screening to be applied to the RSD.
