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

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

    Abstract : 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.

  3. 3. Mathematical Optimization of HDR Brachytherapy

    Author : Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Jeroen Beliën; Linköpings universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  4. 4. Platelets and airway remodeling : Mechanisms involved in platelet-induced fibroblast and airway smooth muscle cell proliferation in vitro

    Author : Ann-Charlotte B. Svensson Holm; Torbjörn Bengtsson; Eva Lindström; Mikael Adner; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : Airway remodeling is a contributing cause to the pathological structural changes, such as increased cell proliferation, observed in asthma. Platelets have been found in autopsy lungmaterial obtained from asthmatic patients and are well known to induce proliferation in vitro of a variety of cells. READ MORE

  5. 5. Parastomal hernia : clinical studies on definitions and prevention

    Author : Arthur Jänes; Leif Israelsson; Åke Öberg; Torbjörn Holm; Umeå universitet; []
