Paper Abstract

Detectors of varying dimensions and geometry may be built using plastic scintillating optical fibers. This paper presents a study of the imaging properties of these detectors, directed at assessing the relative advantages of different designs. To this end, the radionuclide source distribution in the object is reconstructed by solving the inverse problem, using generalized matrix inversion. Photon detection matrices, as is well known, are ill-conditioned, a problem which may be dealt with by using truncated singular value decomposition. The design of the imaging device is investigated in term of minimizing these effects on the system matrix, and the effect of different geometric design parameters is examined. Experimental data obtained with small-scale cylindrical and planar devices are presented for different collimation schemes.
