31. Analysis of Electrocardiograms Using Artificial Neural Networks
Sammanfattning : Most conventional ECG interpretation programs use decision tree logic for interpretation of the ECG. The performance is generally good but can be improved. Artificial neural networks represent a new computer method, which has proved to be of value in pattern recognition and classification tasks. LÄS MER
32. The matter of white matter in Alzheimer's disease. -On white matter disease from neuropathology and neuroimaging to clinical presentation
Sammanfattning : Alzheimer's disease (AD) is the most prevalent type of dementing disorder. The cortical pathology of AD has been recognized for almost a century. In later years, an associated pathological feature of AD has been identified which affects the white matter. LÄS MER
33. Radiotherapy Gel Dosimetry: Development and Application of Normoxic Polymer Gels
Sammanfattning : In many radiotherapy applications, true three-dimensional dosimetry with good spatial resolution that can be achieved in a single measurement would be of great value. Polymer gel dosimetry fulfils many of the demands on such a system. In this study, methods to facilitate the implementation of gel dosimetry have been investigated. LÄS MER
34. Ensuring the intended volume is given the intended absorbed dose in radiotherapy: Managing geometric variations and treatment hazards
Sammanfattning : Methods for ensuring that the intended volume receives the intended absorbed dose in radiotherapy have been investigated. In order to optimise radiation treatment of cancer, geometric variations in the treatment chain need to be controlled. Furthermore, hazards potentially leading to unintended irradiation need to be controlled. LÄS MER
35. Evaluation of MRI as a diagnostic method in biliary tract conditions
Sammanfattning : The diagnostic value of modern fast pulse sequences and breath-hold technique was evaluated in a prospective study of patients with suspected biliary diseases. The cost-effectiveness of MRI compared to ultrasound was calculated. LÄS MER
