1. Automated radiation therapy treatment planning by increased accuracy of optimization tools
Sammanfattning : 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. LÄS MER
2. Implementation of MRI gel dosimetry in radiation therapy
Sammanfattning : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. LÄS MER
3. On Quality in Radiotherapy Treatment Plan Optimisation
Sammanfattning : 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. LÄS MER
4. Treatment Planning of High Dose-Rate Brachytherapy - Mathematical Modelling and Optimization
Sammanfattning : 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. LÄS MER
5. Integration of MRI into the radiotherapy workflow
Sammanfattning : The modern day radiotherapy treatments are almost exclusively based on computed tomography (CT) images. The CT images are acquired using x-rays, and therefore reflect the radiation interaction properties of the material. LÄS MER
