  1. 11. Segmented HPGe detectors for post-irradiation examination of nuclear fuel : Design and demonstration in gamma emission tomography

    Författare :Vikram Rathore; Peter Andersson; Erik Andersson Sundén; Ane Håkansson; Andrew Boston; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmented HPGe detector; Nuclear fuel; Post-irradiation examination; Nuclear fuel diagnostics; Gamma emission tomography; Gamma spectroscopy; Non-destructive fuel testing; Applied Nuclear Physics; Tillämpad kärnfysik;

    Sammanfattning : Gamma emission tomography (GET) is a proven non-invasive technique for post-irradiation examination of nuclear fuel. In the past, collimated HPGe detectors were used for GET measurements due to their good energy resolution. LÄS MER

  3. 12. Optical Coherence Tomography for Dermatological Applications

    Författare :Jakob Borup Thomsen; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; medical imaging; skin cancer diagnostics; optical imaging; blood flow; treatment monitoring;

    Sammanfattning : Optical coherence tomography (OCT) is a non-invasive optical imaging technique providing approximately 10 micrometer resolution of tissue in vivo. Within ophthalmology, OCT has already proven its value and is routinely used for diagnosing retinal diseases. LÄS MER

  4. 13. On Calibration Algorithms for Real-Time Brain-Computer Interfaces

    Författare :Frida Heskebeck; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A Brain-Computer Interface (BCI) is a system that, in real-time, translates the user's brain activity into commands that can be used to control applications, such as moving a cursor on the screen. The translation is made possible by machine learning methods and other algorithms. LÄS MER

  5. 14. Positron Emission Tomography and Magnetic Resonance Techniques in Diabetes

    Författare :Lina Carlbom; Håkan Ahlström; Olle Korsgren; Olof Eriksson; Lars Johansson; Tove Grönroos; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; Magnetic resonance imaging; Magnetic resonance spectroscopy; Type 1 diabetes; Type 2 diabetes; PET MR; Pancreas transplantation; Perfusion; Radiology; Radiologi;

    Sammanfattning : In order to further advance the field of diabetes research there is a great need for establishing validated non-invasive quantitative techniques to study the pancreas and other tissues of importance for blood glucose regulation. The general aim of this thesis was to explore magnetic resonance techniques and positron emission tomography as such tools. LÄS MER

  7. 15. Arrhythmogenic right ventricular cardiomyopathy : Is it right?

    Författare :Meriam Åström Aneq; Eva Nylander; Jan Engvall; Maria Eriksson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited heart disease, where sudden cardiac death in young seemingly healthy persons may be the first symptom. There is a need for more sensitive and accurate diagnostic methods to detect signs of disease, at an early stage and in relatives of affected individuals. LÄS MER
