  1. 1. lntrafractional motion effects during stereotactic body radiation therapy of lung tumors

    Författare :Sebastian Sarudis; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motion effects; Interplay; SBRT; SGRT; Lung tumors; VMAT; CA;

    Sammanfattning : Abstract: Patient shifts and tumor motions occurring during stereotactic body radiation therapy (SBRT) have been analyzed to determine the related effects on the delivered dose. Methods: 4-dimensional computed tomography series were retrospectively reviewed to characterize respiratory-induced lung tumor motions in 126 patients. LÄS MER

  3. 2. 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. Motion management optimization in radiotherapy : From the most common to the most uncommon patient

    Författare :Annika Mannerberg; Lund Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; Motion management; SGRT; SGRT; Motion management; Radiotherapy; Fysicumarkivet A:2023:Mannerberg;

    Sammanfattning : In radiotherapy (RT), the treatment is thoroughly planned and optimized to fulfil the goal of delivering a high dose to the target, while sparing as much normal tissue as possible. This implies that the patient position and anatomy should be the same as they were during the planning image acquisition. LÄS MER

  5. 4. Patient Positioning in Radiotherapy Using Body Surface Scanning

    Författare :Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; positioning; body surface; laser scanning; cancer; SGRT; ITV; lung cancer; surrogate; tumour motion; 4DCT; Medicinsk radiofysik; Medical Radiophysics;

    Sammanfattning : External radiotherapy uses ionising radiation to damage the DNA of the tumour cells and thereby inhibit their uncontrolled proliferation. The technical development regarding imaging and visualisation for radiotherapy has increased considerably during the last decades. LÄS MER
