RESEARCH INTERESTS:

  • High resolution X and gamma ray detectors for radiological imaging applications. We are developing a novel energy-resolved photon-counting (ERPC) sensor that combines compact, high-resolution CdTe or CZT detectors with custom-designed readout electronics. This detector provides an excellent candidate for the next generation SPECT and PET systems.
  • Ultra-high resolution SPECT system for small animal brain studies. The emphasis of this work is to develop a so-called single-photon emission microscope (SPEM) system that offers a sub-hundred micro spatial resolution, while providing an adequate detection efficiency for in vivo mouse brain studies.
  • Multi-modality imaging systems. In this effort, we are developing instruments that allow simultaneous SPECT/MRI, SPECT/CT data acquisition. The SPECT/MRI instrucment will be based on high resolution CdTe detectors customized for operation in strong magnetic field.
  • Statistical and computional approaches for the design and optimization of nuclear imaging system.
