Abstract

The new high performance radioisotopic imager IRIS we recently developed has an intrinsic spatial resolution of about 1.7 mm. To obtain a good sensitivity, it is necessary to use a collimator with holes greater than this spatial resolution. However, this induces artifacts in images. In this paper, we describe a new concept: a moving collimator. Deterministic and Monte Carlo simulations demonstrate that it is possible to obtain simultaneously global high spatial resolution and good sensitivity in radioisotopic imaging.
