  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

  3. 2. Comparative Treatment Planning in Radiotherapy and Clinical Impact of Proton Relative Biological Effectiveness

    Författare :Jonas Johansson; Bengt Glimelius; Anders Montelius; Tony Lomax; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; Comparative studies; Breast cancer; hypopharyngeal cancer; rectal cancer; Proton RBE; Onkologi; Oncology; Onkologi;

    Sammanfattning : The development of new irradiation techniques is presently a very active field of research with increased availability of more sophisticated modalities such as intensity modulated photons (IMRT), protons and light ions. The primary aim of this work is to evaluate if the dose-distributions using IMRT and protons contribute to clinical advantages. LÄS MER

  4. 3. Dosimetric effects of breathing motion in radiotherapy

    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

    Sammanfattning : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. LÄS MER

  5. 4. 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
