1. 1. Silicon Strip Detectors for Scanned Multi-Slit X-Ray Imaging

   Författare :Mats Lundqvist; KTH; []
   Nyckelord :x-ray; silicon strip detectors; mammography; multi-slit; scanned slit; edge-on;

   Sammanfattning : 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. LÄS MER

   Författare :Hans Bornefalk; Mats Danielsson; Robert Nishikawa; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer-aided detection; FROC; mammography; optimal operating points; single-shot dual-energy imaging; Radiological physics; Radiofysik;

   Sammanfattning : 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. LÄS MER
