Summit debuts second-generation digital

While other nuclear medicinevendors play catch up by adding digital to their gamma cameras,digital pioneer Summit Nuclear will display its second-generationall-digital gamma cameras, FX-80 and FX-40.

The cameras will make their RSNA debut after being introducedat the Society of Nuclear Medicine meeting earlier this year (SCAN6/15/94). FX-80 is a dual-head system, while FX-40 is a single-headcamera, according to Gary Enos, vice president. Summit, of Twinsburg,OH, expects to begin shipping the FX line next month.

Summit's first-generation cameras, T-22 and 1024-RZ, were developedin cooperation with Hitachi. The FX series, however, has beendesigned and manufactured solely by Summit, Enos said. T-22 and1024-RZ will continue to be offered.

The FX cameras feature slip-ring technology and rectangulardetectors that use the detector head's entire field-of-view forimaging. Summit will showcase its work in 511-KeV imaging forthe dual-head camera, which uses a coincidence counting methodthat allows each detector to decode independently. This improvesimage quality in 511-KeV studies.
