17. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella
Sammanfattning : The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with special reference to the dislocating patella. LÄS MER
18. Computed Tomography of the Coronary Arteries : Developmental and Prognostic Investigations
Sammanfattning : Computed tomography (CT) is an increasingly used modality for investigations of patients with suspected coronary artery disease (CAD). Technical advances could improve diagnostic accuracy and lead to clinical workflow improvements. Also, more prognostic information can optimize clinical follow-up strategies and treatments. LÄS MER
19. Spectral Computed Tomography with a Photon-Counting Silicon-Strip Detector
Sammanfattning : Computed tomography (CT) is a widely used medical imaging modality. By rotating an x-ray tube and an x-ray detector around the patient, a CT scanner is able to measure the x-ray transmission from all directions and form an image of the patient’s interior. LÄS MER
20. Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation
Sammanfattning : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. LÄS MER
