    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...

  2. 94. Position-sensitive Solid-state Photomultiplier Devices
    Christopher Stapels (Radiation Monitoring Devices)

    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...

  3. 85. A modular positron camera for positron emission particle tracking in harsh environments
    Dr Thomas Leadbeater (University of Birmingham)

    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...
