Multivariate Statistical Methods that Enable Fast Raman Spectroscopy
… optical filters to efficiently capture Raman photons and multiplex them onto either one or two photon counting detector(s). This method, referred to as optimal-binary compressive detection (OB-CD), allows for the collection of chemical information in 10’s of microseconds, rather than …

A photon counting pixel detector for x-ray imaging
Hybrid semiconductor pixel detector technology is presented in this thesis as an alternative to current imaging systems in medical imaging and synchrotron radiation applications. The technology has been developed from research performed in High Energy Physics, in particular, for the ATLAS …

Development of an MR-compatible SPECT system based on energy resolved photon counting detectors
… in the clinical diagnosis and therapy. Single Photon Emission Computed Tomography (SPECT) is one of the most important nuclear imaging modalities, and it gives the functional imaging of the region of interest. MR can provide the anatomical imaging and enjoys better soft tissue contrast …

Assessment and optimisation of digital radiography systems for clinical use
… to be relatively more sensitive to changes in detector performance. The advent of DR systems and access to digital image data has opened up new opportunities in applying such measurements to routine quality control and this project initially focuses on obtaining NPS and MTF results for 12 IDR …

Development of high performance single photon emission computed tomography systems for simultaneous nuclear molecular imaging and magnetic resonance imaging
… effort to develop high-performance single-photon emission computed tomography (SPECT) systems for simultaneous NMI/MRI. This kind of system has sub-mm and even higher resolving power that allows a matched resolution for SPECT and MRI to visualize details about cell retention and migration, …
