2. 1. On Quality in Radiotherapy Treatment Plan Optimisation

   Author : Hunor Benedek; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Pareto optimisation; Pareto fronts; Dose prediction; Machine learning; Deliverable treatment plans; Volumetric modulated arc therapy; IMRT; patient-specific plan quality; plan quality; Multi Criteria Optimisation; Automated Treatment Planning;

   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. 2. Dosimetric effects of breathing motion in radiotherapy

   Author : Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

   Abstract : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. READ MORE

5. 3. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

   Author : Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

   Abstract : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. READ MORE

6. 4. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study

   Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Treatment planning; gastric cancer; liver metastases; photon beam therapy; proton beam therapy; dosimetric comparison; normal tissue complication probability; risk of radiation-induced secondary cancer; patient selection; Medical Radiation Physics; medicinsk strålningsfysik;

   Abstract : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. READ MORE

7. 5. Patient Positioning in Radiotherapy Using Body Surface Scanning

   Author : Kenneth Wikström; Anders Ahnesjö; Sven Bäck; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; positioning; body surface; laser scanning; cancer; SGRT; ITV; lung cancer; surrogate; tumour motion; 4DCT; Medicinsk radiofysik; Medical Radiophysics;

   Abstract : External radiotherapy uses ionising radiation to damage the DNA of the tumour cells and thereby inhibit their uncontrolled proliferation. The technical development regarding imaging and visualisation for radiotherapy has increased considerably during the last decades. READ MORE
