6. 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

7. Mammography Screening-Factors affecting Tumour Stage and Outcome
Abstract : The aim of this thesis was to investigate screening mammography in relation to factors affecting tumour stage and outcome. The main focus was on obesity, tumour biology and breast density. We hypothesized that obese and overweight women could benefit more from screening detection than normal weight women. READ MORE

8. Breast tomosynthesis – new perspectives on breast cancer screening
Abstract : Abstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. READ MORE

9. Breast cancer risk assessment and detection in mammograms with artificial intelligence
Abstract : Breast cancer, the most common type of cancer among women worldwide, necessitates reliable early detection methods. Although mammography serves as a cost-effective screening technique, its limitations in sensitivity emphasize the need for more advanced detection approaches. READ MORE

10. Silicon Strip Detectors for Scanned Multi-Slit X-Ray Imaging
Abstract : Digital imaging systems for medical applications must bebased upon highly efficient detectors to ensure low patientdose. This is particularly important in screening mammographybecause of the large number healthy women that is examined. Amammography system must also provide high spatial and contrastresolution. READ MORE
