1. Characterization and Optimization of Silicon-strip Detectors for Mammography and Computed Tomography
Abstract : The goal in medical x-ray imaging is to obtain the image quality requiredfor a given detection task, while ensuring that the patient dose is kept as lowas reasonably achievable. The two most common strategies for dose reductionare: optimizing incident x-ray beams and utilizing energy informationof transmitted beams with new detector techniques (spectral imaging). READ MORE

2. Image Analysis and Enhancement with Applications in Medicine
Abstract : This thesis consists of six parts in which methods for image analysis and processing are studied. Two-dimensional medical images, image sequences, and three-dimensional image volumes are considered. READ MORE

3. Spectral Photon-Counting Computed Tomography with Silicon Detectors: New Models and Applications
Abstract : X-ray computed tomography (CT) is a widely used imaging modality that enables visualization of nearly every part of the human body. It is used for diagnosis of disease and injury as well as medical treatment planning. READ MORE

4. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy
Abstract : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. READ MORE

5. Techniques for the determination of the optimal performance of high resolution computerised tomography
Abstract : Techniques to deternine the optimal performance of high resolution computerised tomography (CT) has been studied, that is, optimal data collection parameter settings for the imaging task at issue and its detectability limits.Generally, CT is an X-ray based non-destructive testing method that was developed for medical purposes in the seventies and introduced for industrial applications the latter half of the eighties.
