1. 11. Volume imaging of the abdomen : three-dimensional visualisation of tubular structures in the body with CT and MRI

   Författare :Anders Persson; Örjan Smedby; Håkan Ahlström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The overwhelming amount of image-based information in modem medicine makes it crucial to develop methods to handle and analyze images and make them comprehensible for users. The aim of this thesis was to study the radiological practice of three-dimensional (3D) visualization of tubular structures in the body with CT and MRI. LÄS MER

   Sammanfattning : Propagation phase-contrast synchrotron radiation microtomography is a non-destructive method used for studying histology in three dimensions (3D). Using it, the 3D organization of the diaphyseal cortical vascularization in the humerus of two seymouriamorphs was analyzed in this thesis. LÄS MER

4. 13. Development of Time Resolved Laser Imaging Techniques for Studies of Turbulent Reacting Flows

   Sammanfattning : The mouse pancreas is a mixed exocrine and endocrine glandconsisting of three lobular compartments: the splenic, duodenal and gastric lobes. During embryogenesis, the pancreas forms from two progenitor populations located on the dorsal and ventral side of the primitive gut tube. LÄS MER
