2. 1. Resource efficient automatic segmentation of medical images

   Author : Minh Hoang Vu; Tommy Löfstedt; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Örjan Smedby; Umeå universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. On the use of computed tomography in cardiac imaging

   Author : Jakob De Geer; Anders Persson; Jan Engvall; Michael Sandborg; Örjan Smedby; Åse Johnsson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : 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. 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. Imaging the tumor microenvironment : the dynamics and modification of hypoxia

   Author : Anna Ljungkvist; Peggy L. Olive; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; tumor microenvironment; double hypoxic marker method; proliferation; hypoxia; hypoxic half-life; Radiologisk forskning; Radiological research; Radiologisk forskning; diagnostisk radiologi; Diagnostic Radiology;

   Abstract : The tumor vasculature is poor and heterogeneous which may result in inadequate oxygenation and changed energy status. In addition the balance between cell proliferation and the rate of cell death is disturbed, which results in tumor growth. READ MORE

7. 5. Imaging and modeling the cardiovascular system

   Author : Elira Maksuti; Michael Broomé; Anna Bjällmark; Matilda Larsson; Martin Ugander; Patrick Segers; KTH; Karolinska Institutet; Karolinska Institutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cardiac pumping; diastolic function; hemodynamics; modeling; simulation; arterial stiffness; ultrasound; shear wave elastography.; Medical Technology; Medicinsk teknologi; Cardiac pumping;

   Abstract : Understanding cardiac pumping function is crucial to guiding diagnosis, predicting outcomes of interventions, and designing medical devices that interact with the cardiovascular system.  Computer simulations of hemodynamics can show how the complex cardiovascular system is influenced by changes in single or multiple parameters and can be used to test clinical hypotheses.
