The OMEGA 500 single photon emission computerized tomography (SPECT) system made in USA
has been improved in energy resolution
integration linearity and uniformity from 13.2%
0.88mm and 5.2% to 10.9%
0.82mm and 4.2%
respectively) by using a microprocessor SENTINEL instead of conventional electronic circuits. SENTINEL is composed of MC 68000 microprocessor chips and a software package
allowing to perform the corrections of the SPECT system under different energies
radioactive sources and a variety of collimation. The correction data are stored on a floppy disc and can ready to be accessed.
