2. 1. Evaluation of absorbed dose and image quality in mammography

   Author : Bengt Hemdal; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optically stimulated luminescence; radioluminescence; in vivo dosimetry; dose reduction; dose protocol; average glandular dose; absorbed dose; Breast cancer; mammography; Monte Carlo; image quality; image quality criteria; contrast-detail phantom;

   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

4. 2. Decision support for multi-criteria evaluation of manufacturing reshoring decisions

   Abstract : Reshoring decisions in the manufacturing sector have received increasing attention due to their potential to improve overall quality, flexibility, or reduce risk. Contemporary events such as the pandemic and the supply crisis have made manufacturing reshoring decisions a timely and important topic to study. READ MORE

5. 3. Deep Regression and Segmentation for Medical Inference from Large-Scale Magnetic Resonance Imaging

   Author : Taro Langner; Joel Kullberg; Anders Eklund; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetic resonance imaging; medical image analysis; neural networks; machine learning; semantic segmentation; deep regression; saliency analysis; uncertainty quantification; UK Biobank; Medical Informatics; Medicinsk informatik;

   Abstract : Large-scale studies, such as UK Biobank, acquire medical imaging data for thousands of participants. With magnetic resonance imaging (MRI), comprehensive representations of human anatomy can be provided for non-invasive assessments of health-related conditions, body composition, organ volumes, and more.

6. 4. Quality of maternal healthcare : Exploring severe maternal outcomes and the influence of delays and decision-making on caesarean sections in a low-resource setting

   Author : Jonah Kiruja; Marie Klingberg-Allvin; Fatumo Osman; Helena Litorp; Abdi Gele; Högskolan Dalarna; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somaliland; maternal mortality; delayed caesarean section; maternal near miss; severe maternal outcomes; emergency obstetric care; low resource setting;

   Abstract : Somaliland has one of the highest maternal mortality rates worldwide, yet there is limited evidence for severe maternal outcomes and challenges with the provision and utilisation of emergency obstetric care (EmOC). This thesis studied quality of maternal healthcare by exploring severe maternal outcomes and the influences of delays and decision-making on caesarean sections in Somaliland. READ MORE

7. 5. Towards Automatic Image Analysis for Computerised Mammography

   Author : Christina Olsén; Frank Drewes; Fredrik Georgsson; Gunilla Borgefors; Umeå universitet; []
