Abstract

A method and apparatus for increasing the resolution of Positron Emission Tomography scanner (20). The method and apparatus comprise elements and acts for centering a region of interest of an object (24) at a point (36) between first and second detector arrays (26,28) which is at least about ten percent closer to the first detector array (26) than to the second detector array (28).
