PET applications
Oral Presentation
We have developed a new type of large-area monolithic Multi-Pixel Photon Counter (MPPC) array consisting of a 4x4 matrix of 3x3 mm^2 pixels. Each pixel comprises 3600 Geiger mode avalanche photodiodes that achieve an average gain up to 10^6 with variations of only +/- 7% over 4x4 pixels. Excellent uniformity was also obtained for photon detection efficiencies (PDE) of +/-6%. We fabricated a...

PET applications
Oral Presentation
Nuclear imaging applications, such as PET, often use position-sensitive photodetectors coupled to scintillation detectors, to determine the location and energy of the event in a scintillation detector. Coupling nuclear imaging techniques to magnetic-resonance imaging, for morphological images, introduces a strong magnetic field that constrains the choice of photodetector. Solid-state...

PET applications
Oral Presentation
By detecting the back-to-back gamma ray emissions from a positron emitting tracer particle high speed and accurate tracking can be achieved as it moves throughout the field of view of a positron camera; this forms the basis of the technique Positron Emission Particle Tracking (PEPT), developed at Birmingham for over 25 years. The ability to track either particles or neutrally buoyant flow...
