  1. 1. Dose Plan Optimization in HDR Brachytherapy using Penalties : Properties and Extensions

    Författare :Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Göran Sporre; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; MATHEMATICS; MATEMATIK;

    Sammanfattning : High dose-rate (HDR) brachytherapy is a specific type of radiotherapy used to treat tumours of for example the cervix, prostate, and breasts. In HDR brachytherapy applicators are implanted into or close to the tumour volume. A radioactive source is moved through these applicators and stops at certain positions, known as dwell points.

  2. 2. Mathematical Optimization of HDR Brachytherapy

    Författare :Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Jeroen Beliën; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : One out of eight deaths throughout the world is due to cancer. Developing new treatments and improving existing treatments is hence of major importance. In this thesis we have studied how mathematical optimization can be used to improve an existing treatment method: high-dose-rate (HDR) brachytherapy. LÄS MER

  3. 3. Lithium formate EPR dosimetry for accurate measurements of absorbed dose in radiotherapy

    Författare :Emelie Adolfsson; Åsa Carlsson Tedgren; Eva Lund; Håkan Gustafsson; Sara Olsson; Gudrun Alm Carlsson; Peter Sharpe; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Lithium formate has shown to be a material with properties suitable for electron paramagnetic resonance (EPR) dosimetry, among them up to 7 times higher sensitivity compared to alanine, which is a well-established EPR detector material for dose determinations in radiotherapy.The aim of this thesis was to further investigate the properties of lithium formate and develop the dosimetry system towards applications in radiotherapy.

    Sammanfattning : Cancer is a widespread type of diseases that each year affects millions of people. It is mainly treated by chemotherapy, surgery or radiation therapy, or a combination of them. One modality of radiation therapy is high dose-rate brachytherapy, used in treatment of for example prostate cancer and gynecologic cancer. LÄS MER
