Digital imaging techniques have been applied clinically to facilitate cancer screening and diagnosis.  The transition from an analog to digital technique expands the potential of medical imaging, and leads to improved diagnosis at potentially lower radiation and/or cost.  This presentation analyses contemporary detectors techniques and innovative systems.   Methods for characterizing their performance under clinical conditions will also be discussed.
