A mobile gamma camera system for 3D acute myocardial perfusion imaging

A mobile tomographic gamma camera has been developed to enable three-dimensional perfusion studies in the emergency room and in the intensive care environment. The system, Cardioatom, is based on the limited view angle method Ectomography and comprises a modern detector head equipped with a rotating slant hole collimator and specially developed hardware and software for data acquisition, processing and display. Two systems have been developed. The first system, is currently in use at the Karolinska Hospital for a blind comparative study with SPECT, for infarction treatment assessment and in animal experiments. The second system is to be used at the Huddinge University Hospital for intraoperative and acute cerebral perfusion studies, and for myocardial infarction treatment assessment.
