Dr Raj Kumar Panta

PositionResearch Fellow
DepartmentDepartment of Radiology (Christchurch)


My research interests are:
  • Development of photon-counting spectral CT
  • Characterisation and calibration of pixels of spectral x-ray detectors (photon-counting energy-resolving detectors)
  • Clinical and pre-clinical applications of spectral CT
  • Optimisation of application-specific imaging
