A portable camac LabVie wnuclear medicine imaging system

The use of intraoperative devices requires compact detectors and portable imaging systems. In order to image the biodistribution of radiolabeled monoclonal antibodies at surgery, Radiation Monitoring Devices (RMD) developed a small (3" diameter) scintillation camera using a Hamamatsu position sensitive photomultiplier tube (psPMT )coupled to a collimated NaI(Tl) scintillator [1] .The portable data acquisition system we developed and used to collect and display images was coupled to a Macintosh IIfxcomputer via CAMAC-based nuclear electronics. The system software has been written in LabView 2.2 (National Instruments Corp.). The design of the system is presented along with an evaluation of its performance in planar and tomographic image reconstruction. Software for data acquisition, planar and tomographic image analysis and display was written entirely in LabView 2.2.
