  2. 1. A study of some energy dependent characteristics of X-ray screens used in diagnostic radiology : screen-film sensitivity, MTF and some related factors

    Author : Mikael Karlsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensifying screens; x-ray screens; fluorescent screens; modulation transfer function; MTF; x-ray screen sensitivity; fluorescent K-radiation sources;

    Abstract : Fluorescent x-ray screens are used in medical x-ray diagnostics to absorb x-ray photons and convert these x-ray photons to visible light. The light distribution from these screens are then registered on photographic film to give an x-ray image. READ MORE

  4. 2. Advanced X-ray Detectors for Industrial and Environmental Applications

    Author : Salim Reza; Christer Fröjdh; Börje Norlin; Heinz Graafsma; Fulvia Arfelli; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering;

    Abstract : The new generation of X-ray free electron laser sources arecapable of producing light beams with billion times higherpeak brilliance than that of the best conventional X-ray sources.This advancement motivates the scientific community to pushforward the detector technology to its limit, in order to de-sign photon detectors which can cope with the extreme fluxgenerated by the free electron laser sources.

  5. 3. Time-Resolved and High-Energy Synchrotron Radiation Crystallography using X-ray Area Detectors: Calibration and Applications

    Author : Olof Svensson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis relates to characterisation and calibration techniques for X-ray area detectors with applications in time-resolved and high-energy X-ray crystallography. X-ray crystallography is an interdisciplinary science with important applications in many fields, e.g. chemistry, physics, biology, geology and materials science. READ MORE

  6. 4. Architecture and circuit design of photon counting readout for X-ray imaging sensors

    Author : Suliman A Abdalla; Bengt Oelmann; Kenway Smith; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : Hybrid pixel array detectors for X-ray imaging are based on different technologies for sensor and readout electronics. The readout electronics are based on standard CMOS technologies that are experiencing continuously rapid improvements by means of down-scaling the feature sizes, which in turn lead to higher transistor densities, lower power consumption, and faster circuits.
