2. 1. Structural properties of the mastoid using image analysis and visualization

   Author : Olivier Cros; Michael Gaihede; Hans Knutsson; Bernard Ars; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : The mastoid, located in the temporal bone, houses an air cell system whose cells have a variation in size that can go far below current conventional clinical CT scanner resolution. Therefore, the mastoid air cell system is only partially represented in a CT scan. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography

   Author : Cheng Xu; Hans Bornefalk; Mats Danielsson; Ami Altman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photon counting; spectral computed tomography; silicon strip detector; ASIC; energy resolution; cadmium telluride; charge sharing; Monte Carlo simulation; synchrotron;

   Abstract : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.

6. 4. Efficient Medical Volume Visualization : An Approach Based on Domain Knowledge

   Author : Claes Lundström; Anders Ynnerman; Hans Knutsson; Dirk Bartz; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scientific Visualization; Medical Imaging; Computer Graphics; Volume Rendering; Transfer Function; Level-of-detail; Fuzzy Classification; Uncertainty Visualization; Virtual Autopsies; Medical engineering; Medicinsk teknik;

   Abstract : Direct Volume Rendering (DVR) is a visualization technique that has proved to be a very powerful tool in many scientific visualization applications. Diagnostic medical imaging is one domain where DVR could provide clear benefits in terms of unprecedented possibilities for analysis of complex cases and highly efficient work flow for certain routine examinations.

7. 5. The transferrin polymorphism : population genetics and associations with reproductive hazards and disease

   Author : Carin Sikström; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Human serum transferrin (TF) carries iron from the intestine, reticuloendothelial system and liver parenchymal cells to proliferating cells in the body. TF is highly polymorphic, and previous findings of associations between TF types and reproductive hazards in different species suggest that the TF polymorphism may be involved in natural selection and susceptibility to disease.
