1. Digital Mammography with a Photon Counting Detector in a Scanned Multislit Geometry
Abstract : Mammography screening aims to reduce the number of breast cancer deaths by early detection of the disease, which is one of the leading causes of deaths for middle aged women in the western world. The risk from the x-ray radiation in mammography is relatively low but still a factor in the benefit-risk ratio of screening. READ MORE

2. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis
Abstract : Breast cancer is the most common form of cancer affecting women in the western countries. Today x-ray digital mammography (DM) of the breast is commonly used for early detection of breast cancer. However, the sensitivity of mammography is limited, mainly due to the fact that a 3D volume is projected down to a 2D image. READ MORE

3. Computer-aided detection and novel mammography imaging techniques
Abstract : This thesis presents techniques constructed to aid the radiologists in detecting breast cancer, the second largest cause of cancer deaths for western women. In the first part of the thesis, a computer-aided detection (CAD) system constructed for the detection of stellate lesions is presented. READ MORE

4. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography
Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE

5. Evaluation of absorbed dose and image quality in mammography
Abstract : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. READ MORE
