1. A method of increasing resolution of an image of a region of interest of an object provided by a positron emission tomography scanner comprising opposing first and second detector arrays spaced by a distance, said method comprising the steps of:
centering the object at a point between the first and second detector arrays closer to said first detector array than to said second detector array;
centering the region of interest of the object at a point between the first and second detector arrays at least about ten percent closer to said first detector array than to said second detector array; and
scanning the object with the scanner.
