Abstract:
An apparatus for use in positron emission comprising:a first detector having a radiation sensitive face which faces an examination region;a second detector having a radiation sensitive face which faces the examination region, the second detector including a plurality of septa disposed between the radiation sensitive face and the examination region, each of the septa including a major axis, the septa having a septal period a in a direction perpendicular to their major axes and a corresponding septal 1/a;means for translating the septa to a plurality n of discrete positions with respect to the examination region, each of the positions being separated by a distance equal to ##EQU3## means operatively connected to the first and second detectors for collecting data indicative of positron annihilation events occurring within the examination region with the septa positioned at each of the plurality of positions.
