The Silicon Drift Detector (SDD) has been successfully employed as scintillation photodetector in the development of new gamma-ray detectors, with particular application in the field of medical imaging. In addition to other advantages, the SDD may offer a good insensitivity to magnetic fields, which represents an important feature for the use of this device in combination with MRI (Magnetic Resonance...
We are combining recent developments in nanomaterials with the concept of silicon photomultipliers (SiPMs) to develop cost-effective, large-area photodetectors for applications in medical imaging and other low-light sensing applications. Silicon nanowires are grown inside of a template made up of an array of insulating nanotubes on a quartz substrate, generating a close-packed array of vertically-oriented...
A method extending the functionality of silicon photomultipliers (SiPMs) has been developed. It enables the use of SiPMs for quantifying high radiation fluxes in current mode as well as in pulse mode measurements for counting and characterizing individual gamma-ray or X-ray photons when coupled to scintillators. This opens new possibilities for multimodal medical imaging by providing the means for...
