“…I n a n effort to improve the visibility of these organs, converging collimation has been employed. Converging collimation provides image magnification and improved system resolution by virtue of a reduction in useful camera field of view, while utilizing a greater fraction of the gamma camera crystal (Rudin, Bardfeld and Hart 1971, Dowdey and Bonte 1972, Murphy, Burdine and Moyer 1975. However, for paediatric studies and some adult studies, such as those of the heart, the gamma camera image with converging collimation still may fill only 3 0 4 0 % of the field of view.…”

A multislice fan beam collimator was designed for a SPECT system with a rotating scintillation camera, and it was constructed by the lead casting method which was devised in recent years. The focal length from the surface of the detector side of the collimator is 75 cm. In order to reconstruct the SPECT images we modified the interpolation method which was developed for reconstruction of the X-ray CT and applied it. Primary photopeak data were obtained with a 20% energy window centered at 140 keV for 99mTc and 159 keV for 123I. The fan beam collimator reduces the field of view, and it would therefore be limited to use only for the head and neck region at present; however, both resolution and sensitivity were approximately 20% better than those of the parallel hole collimator. A fan beam collimator is a useful implement for the SPECT study.
