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

2. Implementation of MRI gel dosimetry in radiation therapy
Abstract : 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. READ MORE

3. On Quality in Radiotherapy Treatment Plan Optimisation
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.

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

5. Integration of MRI into the radiotherapy workflow
Abstract : 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. READ MORE
