Creating Biomedical Technologies to Improve Health


Nuclear Medicine

This program supports the research and development of technologies and techniques that create images out of the gamma-ray or positron (and resulting photon) emissions from radioactive agents that are injected, inhaled, or ingested into the body and then concentrate in specific biological compartments. Active areas supported include the coupling of positron emission tomography (PET) and single photon emission computed tomography (SPECT) to CT and/or to MRI (or other modalities); the design of higher spatial and temporal resolution systems including the compensation for artifacts, improved reconstruction algorithms and the development of new cameras, scintillators and collimators; new approaches to increasing sensitivity and tracking/lowering radiation dose; and software that corrects on the quality and integrity of the acquired data (handles patient motion, intermodality image registration, and dosimetry).
