Physics Instrumentation Group PennPET Explorer scan 1.5hr post-injection


The Physics and Instrumentation Group strives to develop and evaluate new technology for imaging in nuclear medicine, and engages in collaboration with clinicians and research investigators to optimize new instruments for applications in both clinical and pre-clinical (animal) imaging scenarios.

Key Services

  1. New Instrument implementation and testing
  2. Instrument and algorithm optimization to improve imaging performance
  3. Equipment maintenance and upgrades
  4. Translation of novel instruments and technology from lab to research use and clinical practice
