  1. 11. 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.

  3. 12. Axis Fractures in Elderly : Epidemiology and Treatment related outcome

    Författare :Anna-Lena Robinson; Claes Olerud; Yohan Robinson; Bengt Lind; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; odontoid fracture; treatment; elderly; cervical spine; axis fracture; Orthopaedics; Ortopedi;

    Sammanfattning : Background: Axis fractures are a common injury in the elderly population. Treatment is often complicated due to osteoporosis and patient comorbidity. Knowledge of the incidence of these fractures, as well as their treatment, outcome and mortality rate, will improve knowledge and decision-making processes for this fragile group of patients.

  4. 13. Renal Dysfunction and Cardiovascular Disease

    Författare :Inga Soveri; Bengt Fellström; Lars Lind; Ola Samuelsson; Uppsala universitet; []
    Nyckelord :Internal medicine; renal dysfunktion; cardiovascular disease; risk factor; mortality; endothelial dysfunction; arterial stiffness; oxidative stress; inflammation; renal transplantation; haemodialysis; general population; Invärtesmedicin;

    Sammanfattning : Kidney dysfunction increases cardiovascular disease (CVD) risk. The mechanisms for the risk increase seem to involve a combination of traditional and non-traditional CVD risk factors.We studied renal dysfunction as CVD and mortality risk factor in middle-aged men free from diabetes and CVD.

  5. 14. Modeling of dose and sensitivity heterogeneities in radiation therapy

    Författare :Kristin Wiklund; Bengt K. Lind; Iuliana Toma-Dasu; Marco Zaider; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; Tumor control probability; Modeling; Beam characterization; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : The increased interest in the use of light ion therapy is due to the high dose conformity to the target and the dense energy deposition along the tracks resulting in increased relative biological effectiveness compared to conventional radiation therapy. In spite of the good clinical experience, fundamental research on the characteristics of the ion beams is still needed in order to be able to fully explore their use. LÄS MER
