  2. 1. Automated radiation therapy treatment planning by increased accuracy of optimization tools

    Author : Lovisa Engberg; Anders Forsgren; Marina A. Epelman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; intensity-modulated radiation therapy; radiation therapy treatment planning; automated radiation therapy treatment planning; interior-point methods; Optimering; intensitetsmodulerad strålbehandling; dosplanering; automatiserad dosplanering; inrepunktsmetoder; Mathematics; Matematik;

    Abstract : Every radiation therapy treatment is preceded by a treatment planning phase. In this phase, a treatment plan that specifies exactly how to irradiate the patient is designed by the treatment planner. READ MORE

  4. 2. Improving the therapeutic ratio of stereotactic radiosurgery and radiotherapy

    Abstract : Radiotherapy is one of the essential treatments used in the fight against cancer. The goal of radiotherapy is to deliver a high dose of ionising radiation to the tumour volume and at the same time minimise the effect on healthy tissue by reducing the radiation to critical organs.

  7. 5. Treatment Planning of High Dose-Rate Brachytherapy - Mathematical Modelling and Optimization

    Author : Björn Morén; Torbjörn Larsson; Åsa Carlsson Tedgren; Bram Gorissen; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Cancer is a widespread class of diseases that each year affects millions of people. It is mostly treated with chemotherapy, surgery, radiation therapy, or combinations thereof. High doserate (HDR) brachytherapy (BT) is one modality of radiation therapy, which is used to treat for example prostate cancer and gynecologic cancer. In BT, catheters (i. READ MORE
