1. 1. Resource efficient automatic segmentation of medical images

   Författare :Minh Hoang Vu; Tommy Löfstedt; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Örjan Smedby; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; radiotherapy; medical imaging; deep learning; convolutional neural network; generative adversarial network; data augmentation; semantic segmentation; classification; activation map compression; radiofysik; radiation physics;

   Sammanfattning : Cancer is one of the leading causes of death worldwide. In 2020, there were around 10 million cancer deaths and nearly 20 million new cancer cases in the world. Radiation therapy is essential in cancer treatments because half of the cancer patients receive radiation therapy at some point. LÄS MER

3. 2. Är det bara jag? Om sexism och rasism i läkarutbildningens vardag : erfarenheter, förklaringar och strategier bland läkarstudenter

   Författare :Emelie Kristoffersson; Katarina Hamberg; Carita Bengs; Jenny Andersson; Katja Gillander Gådin; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical education; medical students; clinical training; specialty preference; qualitative methods; mixed methods; everyday sexism; everyday racism; gendered microaggressions; racial microaggressions; family medicine; allmänmedicin;

   Sammanfattning : Background: Medical education is characterized by unequal conditions for women/men and white/racialized students. Even subtle interactional processes of inclusion and exclusion convey messages about who rightfully belongs in medical school. Insights into these processes, though, are scarce – especially in the Swedish context. LÄS MER

4. 3. Paternalism in general practice - physician's power and patient's autonomy

   Författare :Stefan Bremberg; Allmänmedicin och klinisk epidemiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; autonomy; Attitudes; interview; justification; medical benefit; paternalism; questionnaire; General practice; medicinsk utbildning; medical training; Allmän medicinsk utövning;

   Sammanfattning : The overall aim of this thesis was to identify and analyse situations raising the question of possible paternalism in everyday general practice in Sweden. Both questionnaires to a random sample of respondents and interviews have been used. LÄS MER

5. 4. Methods for the analysis and characterization of brain morphology from MRI images

   Författare :Irene Brusini; Chunliang Wang; Örjan Smedby; Eric Westman; Lars-Olof Wahlund; Jorge Cardoso; KTH; Karolinska Institutet; Karolinska Institutet; []

   Sammanfattning : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. LÄS MER

7. 5. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

   Författare :Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

   Sammanfattning : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. LÄS MER
