Abstract
A detector particularly suited for use in immuno-guided surgery capable of detecting very faint gamma emissions and thereby localizing cancerous tumor. The detector employs a hand manipular probe within which is contained a crystal such as cadmium telluride which is secured in a light-tight environment. A noise immune structuring of the probe and crystal combination includes the utilization of a resilient compressible shock cushion layer located at one face of the crystal in conjunction with a biasing surface. Additionally, an elastomeric retainer is positioned over the assemblage of crystal, cup, and shock cushion layer to form a sub-assembly for retention within the device. A dead air space is developed between the forward facing window of the probe and the crystal remaining assemblage.
