Diagnostic X-Ray imaging is primarily used for imaging the human body, and advancements in this imaging technology provides medical researchers with new tools to improve care in innovative ways. This invention would benefit applications that require high temporal resolution characterization, which currently relies on streak cameras based on old, expensive vacuum tube technologies.


The approach is to develop a solid-state X-ray imager based on the architecture of the Silicon Drift Detector (SDD) which uses a series of cathode strips on both sides of a silicon wafer to achieve bulk depletion and electron drift.  The invention leverages this SDD functionality to achieve signal stretching of liberated charge carriers from X-Ray photons that converts the time domain into the spatial domain.  This is the key concept behind achieving high temporal resolution in a solid-state device.
