Projects

The goal in medical X-ray imaging is to use the lowest dose of X-ray radiation as is reasonable to get an adequate image. X-ray images have a unique set of characteristics related to the low number of photons used in their production. Methods that use the limited amount of radiation can translate into lower dose and/or better images more efficiently.

Our research includes the following areas of study:

  • the study of the properties of direct and indirect X-ray detection materials and phosphors
  • the development of methods of digitizing the charge image captured in a selenium layer
  • methods of digitally processing X-ray images
  • methods of modulating the X-ray source to provide better image characteristics
