16. Optimisation Of Ionospheric Scintillation Model Used In Radio Occultation
University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandlingAbstract : This thesis is executed in cooperation with RUAG Space AB, which specializes in highly reliable on-board satellite equipment. The thesis focuses on the effect, which disturbs the amplitude and phase of a Global Positioning System (GPS) signal, called scintillation effect. It has a substantial impact on a GPS signal, during Radio Occultation (RO). READ MORE

17. Evaluation of differences in attenuation pattern for myocardial perfusion scintigraphy between CZT and conventional gamma cameras
University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/SjukhusfysikerutbildningenAbstract : The new CZT camera has a different technology compared to conventional scintillation gamma cameras. The CZT camera have pinholes instead of parallel hole collimators, a static gantry instead of a rotating one and detection material made of a semiconductor in- stead of a scintillation crystal.

18. 3D Scintillation Positioning Method in a Breast-specific Gamma Camera
University essay from KTH/Skolan för teknik och hälsa (STH)Abstract : In modern clinical practice, gamma camera is one of the most important imaging modalities for tumour diagnosis. The standard technique uses scintillator-based gamma cameras equipped with parallel-hole collimator to detect the planar position of γ photon interaction (scintillation). READ MORE

20. Compton Imaging with Scintillators in a Virtual Geant4 Space
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/KärnfysikAbstract : In this study the Geant4 toolkit has been used to perform Monte Carlo simulations of relatively inexpensive, inorganic, scintillator-based detectors. Full simulations of the optical photons produced via the scintillation process have been done in order to achieve realistic responses from the attached electro-optical sensors. READ MORE
