This volume addresses four major topical areas: imaging detectors for astrophysics application, noble liquid compound, medical application and high energy application.Noble liquid and scintillating fiber technology, which opened a new era in high spatial (energy) resolution, high speed detection of charged particles and gamma rays, is developing further and its application seems to be concentrated in three major directions: astrophysics, high energy physics and medical imaging. In addition, the book covers new developments in imaging photon detectors, hybrid type (fiber and noble liquid) detectors for WIMP search and several promising techniques for new imaging detectors.
