    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer-aided detection; FROC; mammography; optimal operating points; single-shot dual-energy imaging; Radiological physics; Radiofysik;

    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. 2. 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

  5. 3. Women’s participation in mammography screening

    Abstract : This dissertation focuses on women’s participation in mammography screening, which is a vital component of early detection and effective management of breast cancer. All Swedish women in the age group of 40-74 receive an invitation by mail at regular intervals of 18-24 months. READ MORE

  6. 4. Evaluation of the effectiveness of mammography screening in Northern Sweden

    Author : Pál Bordás; Per Lenner; Håkan Jonsson; Lennarth Nyström; Edward Azavedo; Umeå universitet; []

    Abstract : Service screening with mammography was implemented in Northern Sweden between 1989 and 1998, covering 190,000 women aged 40-74 years constituting the target population in the area. The aim of this thesis was the evaluation of mammography screening in Northern Sweden with special focus on selected screening performance indicators and on the disease outcome. READ MORE

  7. 5. Digital Mammography with a Photon Counting Detector in a Scanned Multislit Geometry

    Author : Magnus Åslund; Mats Danielsson; Ehsan Samei; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mammography; digital; photon counting; scanning; detective quantum effciency; scattered radiation; automatic exposure control; Physics; Fysik;

    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
