Detektor zur Lokalisierung schwacher Strahlungsemissionen |
摘要 |
<p>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 (114) 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 electrically conductive, compliant cushion layer (92) located at one face of the crystal(114) in conjunction with freely abutting biasing and ground contacts (100,112). A nylon, resilient retainer (136) is positioned in tension over the assemblage of crystal (114), ground and biasing contacts (112,122-125,100) and compliant layers (92,120) to achieve a compressively retained assemblage. A dead air space (150) is developed between the forward facing window (18) of the probe and the crystal retaining assemblage.</p> |
