  2. 1. Helical tomotherapy for total marrow and total skin irradiation : Optimisation, verification, and clinical results

    Author : André Änghede Haraldsson; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ALL; Leukemia; radiotherapy; hematology; Oncology; Leukemia; radiotherapy; Tomotherapy; Oncology; ALL;

    Abstract : In modern cancer therapy, radiotherapy (RT) is a vital part of most treatments. Most RT treatments in Sweden are performed using intensity-modulated radiotherapy (IMRT) with fixed or dynamic arc delivery. The dose gradients outside the target are steep, the margins are small, and the treatment delivery is complicated. READ MORE

  4. 2. Dosimetric effects of breathing motion in radiotherapy

    Author : Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

    Author : Caroline Olsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration; xerostomia;

    Abstract : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.

  6. 4. Relative biological effectiveness in proton therapy: accounting for variability and uncertainties

    Author : Jakob Ödén; Iuliana Toma-Dasu; Kjell Eriksson; Radhe Mohan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; relative biological effectiveness; linear energy transfer; proton track-end optimisation; radiation-induced toxicity; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Radiation therapy is widely used for treatments of malignant diseases. The search for the optimal radiation treatment approach for a specific case is a complex task, ultimately seeking to maximise the tumour control probability (TCP) while minimising the normal tissue complication probability (NTCP).

  7. 5. From single-molecule sensing to extracellular vesicles in glioma cells under stress

    Author : Virginia Claudio; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteome; single molecule sensing; nanoplasmonics; surface plasmon resonance; exosomes; glioblastoma; extracellular vesicles; cellular stress; lipid composition;

    Abstract : This thesis describes the work I conducted in two different areas, namely biomolecular sensing and quantitative cell biology. The work in the former area was focused on the optimization of plasmonic metamaterials for sensing applications, and in the latter on the characterization of extracellular vesicles released by glioblastoma cells under stress conditions.
