%X The paper is concerned with parallel image reconstruction.
   The background of parallel image reconstruction has been
   briefly reviewed. Parallel formulations of series expansion
   methods expressed in occam exploiting projection and ray
   parallelisms have been presented. Two types of mapping of
   the projection space onto the image space influencing a
   simultaneous memory access have been defined. Finally,
   several ways of synchronizing the activities of processes
   when accessing the memory have been discussed.
