    The SYRMEP (Synchrotron Radiation for Medical Physics) collaboration is performing, for the first time in the world, a clinical program of Mammography with Synchrotron Radiation (MSR), utilizing a conventional screen-film system to acquire Phase Contrast (PhC) x-ray images. The next stage of the clinical trial will take advantage of a digital detector tailored for the characteristics of the SR...

    The Medipix2 Collaboration, based at CERN, has developed the TimePix version of the Medipix pixel readout chip, which has the ability to provide either an ADC or TDC capability separately in each of its 256 x 256 pixels. When coupled to a Si detector layer, the device is an excellent candidate for application as an active dosimeter for use in Space Radiation Environments. In order to...

    In this paper we propose a new scanner for small-animal positron emission tomography based on stacks of double sided silicon detectors. Each stack is composed of 40 planar detectors with dimension 60× 60×1 mm3 and 128 orthogonal strips on both sides to read the two coordinates of interaction, the third being the detector number in the stack. Multiple interactions in a stack are discarded by an...

    Contributed Talk
    In recent years there has been increased interest throughout the world in the use of proton radiation therapy for treatment of tumors. The new techniques in radiation therapy and widespread use of modern dynamic beam delivery systems demand new beam monitoring devices as well as accurate 2D dosimetry systems to verify the delivered dose distribution. We are developing dose imaging detectors...

  5. 60. Development of an Electron-Tracking Compton Camera using CF4 gas at high pressure for improved detection efficiency
    Mr Michiaki Takahashi (Japan)

    Contributed Talk
    In MeV gamma-ray astronomy, the only observation by a Compton camera, COMPTEL, succeeded. The sensitivity of COMPTEL is, however, worse than those of detectors in the X-ray and other gamma-ray regions for the large background. Therefore a Compton observatory with better sensitivity is required. We have developed an Electron-Tracking Compton Camera (ETCC) consisting of a gaseous micro Time...
