  3. 22. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography

    Författare :Anders Tingberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; normal anatomy; free response forced error FFE ; receiver operating characteristics ROC ; visual grading analysis VGA ; European image criteria; quantifying clinical image quality; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. LÄS MER

  4. 23. Deep Brain Stimulation Atlases in Movement Disorders : from Patient-Specific to Group Analysis

    Författare :Dorian Vogel; Karin Wårdell; Simone Hemm; Anders Eklund; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : deep brain stimulation (DBS) is an established method for symptom control in movement disorders such as Parkinson’s disease (PD) and essential tremor (ET). The treatment consists in delivering electrical stimulation in the deep brain via multi-contact electrodes. LÄS MER

  5. 24. Development of a Whole Body Atlas for Radiation Therapy Planning and Treatment Optimization

    Författare :Sharif Qatarneh; Anders Brahme; Bengt Lind; Anders Ahnesjö; Stockholms universitet; []
    Nyckelord :3D whole body atlas; lymph node topography; matching transformation; radiation therapy planning; radiobiological optimization; segmentation; target volume definition; medicinsk strålningsfysik; Medical Radiation Physics;

    Sammanfattning : The main objective of radiation therapy is to obtain the highest possible probability of tumor cure while minimizing adverse reactions in healthy tissues. A crucial step in the treatment process is to determine the location and extent of the primary tumor and its loco regional lymphatic spread in relation to adjacent radiosensitive anatomical structures and organs at risk.

  7. 25. Exploring Diversity in the Midbrain Dopamine System with Emphasis on the Ventral Tegmental Area

    Författare :Bianca Vlcek; Åsa Mackenzie; Eva Hedlund; Uppsala universitet; []
    Nyckelord :;

    Sammanfattning : Midbrain dopamine neurons of the substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) are important for motor, cognitive and limbic functions through substantial projections to forebrain structures. Dysfunction of the midbrain dopamine system is associated with several disorders, including Parkinson´s disease (PD) and substance use disorder. LÄS MER
