  1. 1. Surface guided radiotherapy

    Författare :Malin Kügele; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surface guided radiotherapy; DIBH; SGRT; radiotherapy; patient positioning; intra-fraction motion; surface imaging; treatment planning; SGRT; surface guided radiotherapy; intra-fraction motion; DIBH; patient positioning; treatment planning; surface imaging;

    Sammanfattning : Modern radiotherapy aims to treat the decease while minimizing the radiation dose to the adjacent normal tissue, to minimize acute and late effects of the treatment. The foremost technological approaches have been intensity modulated radiotherapy (IMRT) and intensity modulated proton therapy (IMPT) in combination with image guided radiotherapy (IGRT). LÄS MER

  4. 3. Probabilistic treatment planning based on dose coverage : How to quantify and minimize the effects of geometric uncertainties in radiotherapy

    Författare :David Tilly; Anders Ahnesjö; Erik Grusell; Uwe Oelfke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; treatment simulation; probabilistic planning; dose calculation; probabilistic optimization; statistical shape model; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. LÄS MER

  5. 4. Towards a balanced radiotherapy workflow using practical solutions identified by field studies and simulations

    Författare :Jesper Lindberg; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; workflow; organization; planning;

    Sammanfattning : With increasing cancer incidence comes a higher demand for radiotherapy (RT). Resources available for RT, well-educated staff, and linear accelerators (linacs), are limited. LÄS MER

  7. 5. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

    Författare :Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Sammanfattning : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. LÄS MER
