| 摘要 |
An inverse collimator detector for nuclear medicine imaging applications is provided. The inverse collimator detector includes an inverse collimator wherein high density, high atomic number collimator material is placed in the location where the conventional collimator has no material, and no material is placed where the conventional collimator has high density, high atomic number collimator material. The inverse collimator detector of the present invention allows significantly higher detection efficiency for incident photons while providing distance information and maintaining high resolution for isolated, small sources of radioactivity associated with molecular imaging agents.
