simulated bone erosions in a hand phantom detection with conventional screen film technology versus Cesium Iodide amorphous silicon flat panel detector
Radiology, 2000Co-Authors: M Strotzer, Markus Völk, Thomas Wild, P Von Landenberg, Stefan FeuerbachAbstract:PURPOSE: To assess the diagnostic performance of an active-matrix flat-panel x-ray detector for reduced-dose imaging of simulated arthritic lesions. MATERIALS AND METHODS: A digital x-ray detector based on Cesium Iodide and amorphous silicon technology with a panel size of 43 × 43 cm, matrix of 3,000 × 3,000 pixels, pixel size of 143 μm, and digital output of 14 bits was used. State-of-the-art screen-film radiographs were compared with digital images obtained at doses equivalent to those obtained with system speeds of 400, 560, and 800. The phantom was composed of a human hand skeleton on an acrylic plate with drilled holes simulating bone erosions of different diameters and depths. Results of four independent observers were evaluated with receiver operating characteristic curve analysis. RESULTS: The Cesium Iodide and amorphous silicon detector resulted in better diagnostic performance than did the screen-film combination, with the dose being the same for both modalities (P < .05). For digital images obt...

Excited State Electronic Properties of Sodium Iodide and Cesium Iodide
Journal of Luminescence, 2013Co-Authors: Luke W. Campbell, Fei GaoAbstract:Abstract We compute from first principles the dielectric function, loss function, lifetime and scattering rate of quasiparticles due to electronic losses, and secondary particle spectrum due to plasmon decay in two scintillating alkali halides, sodium Iodide and Cesium Iodide. Particular emphasis is placed on quasiparticles within several multiples of the bandgap from the band edges. A theory for the decay spectra of plasmons and other electronic excitations in crystals is presented. Applications to Monte Carlo radiation transport codes are discussed.
