Low-Cost PET System Development
Small animal imaging with existing PET systems is an expensive proposition. A system for use with mice only can be physically smaller, and light collection strategies with optical fiber readout can be used to minimize the number of detector and electronics channels necessary to create an image with useful resolution. Our work is directed at evaluating possibilities for detector design and construction. (See Phys med Biol 2007; 52:2499-2514.)

Photograph of a complete detector module made of a 4x4 LSO array with
wavelength shifting fibers on both ends. It also shows an individual LSO
element (1.5x1.5x20mm3, unpolished crystal) and an individual WLS fiber.
An enlarged picture of the array with white reflective polymer films can be
seen in the top right corner.
