Scanner for positron emission computed tomography

A scanner according to caim 2, in which:

• the detectors are arranged in a plural number in each of sections divided by at least one rectilinear line passing through the center of rotation of the rotary member and located in said plane, and in which:
• the spacing between the detectors is different between each of these sections.

A scanner for positron emission computed tomography comprising:

• a rotary member rotatable in a slice plane about a center axis perpendicular to this slice plane and having means for accomodating a subject for examination, a drive means for rotating this rotary member in said slice plane, and at least a pair of detector arrays provided on the rotary member to oppose each other with the center of rotation of this rotary member lying inbetween, those detectors in one of said detector arrays being arranged with spacing different from the spacing between the detectors in the other one of the detector arrays.
