Abstract
A multifield collimator system and radionuclide emission tomography camera using same which include at least two collimator segments whose fields of view in combination define at least two tomographic field of view boundaries. At least one of the boundaries encompasses the region to be imaged of an object. The fields of view may overlap at least in part to produce enhanced imaging sensitivity in the portion of overlap. The tomography camera detects radionuclide emissions from the region to collect at least one collimated image through each segment and combines the collimated images to produce a final image of the region exhibiting enhanced sensitivity in the portion of overlap. A multifield method of collimation is also disclosed.
