6. Towards Automatic Image Analysis for Computerised Mammography
Sammanfattning : Mammographic screening is an effective way to detect breast cancer. Early detection of breast cancer depends to a high degree on the adequacy of the mammogram from which the diagnosis is made. Today, most of the analysis of the mammogram is performed by radiologists. LÄS MER
7. Improving the quality of caesarean section in a low-resource setting : An intervention by criteria-based audit at a tertiary hospital, Dar es Salaam, Tanzania
Sammanfattning : A sharp increase in caesarean section (CS) rates at the Muhimbili National Referral Hospital (MNH) – a tertiary referral hospital in Tanzania – by 50% in 2000–2011, was associated with concomitant increase in maternal complications and deaths and inconsistent improvement in newborn outcomes. The aims of this thesis were to explore care providers’ in-depth perspective of the reasons for these high rates of CS, and to evaluate and improve standards of care for the most common indica-tions of CS, obstructed labour and fetal distress, which are also major causes of adverse maternal and neonatal outcomes.

8. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography
Sammanfattning : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. LÄS MER
9. On the use of computed tomography in cardiac imaging
Sammanfattning : BackgroundCardiac Computed Tomography Angiography (CCTA) is becoming increasingly useful in the work‐up of coronary artery disease (CAD). Several potential methods for increasing the diagnostic yield of cardiac CT are available. LÄS MER
10. Aggregation as Unsupervised Learning in Software Engineering and Beyond
Sammanfattning : Ranking alternatives is fundamental to effective decision making. However, creating an overall ranking is difficult if there are multiple criteria, and no single alternative performs best across all criteria. Software engineering is no exception. LÄS MER
