3. 2. The impact of metallic cranial implants on proton-beam radiotherapy treatment plans for near implant located tumours : A phantom study on the physical effects and agreement between simulated treatment plans and the resulting treatment for near implant located cranial tumours

   University essay from Umeå universitet/Institutionen för fysik

   Author : Adam Sjögren; [2018]
   Keywords : Proton-based Radiotherapy; Cranial implants; Titanium implants; Cancer treatment; metal streak artifacts.;

   Abstract : Within the field of radiotherapy treatments of tumour diseases, the hunt for more accurate and effective treatment methods is a continuous process. For some years ion-beam based radiotherapy, especially the proton-beam based applications, has increased in popularity and availability. READ MORE

4. 3. Skin dose measurement during radiation therapy of mastectomy patients using GafChromicTM EBT3 films.

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Madeleine Bergström; [2017]
   Keywords : Mastectomy; Radiation therapy; GafChromic; EBT3; microcirculation;

   Abstract : Purpose: The aim of this study was to develop a method of measuring changes in the skin microcirculation and skin dose for mastectomy patients in connection with the radiation treatment. The distribution of the skin dose, its dependence on the energy of the beam, field geometry and bolus material and the accuracy of the given skin dose in the treatment planning system were studied.

5. 4. Validation of the Eclipse(TM) Treatment Planning System for Synchrotron Microbeam Radiotherapy

   University essay from Lunds universitet/Medicinsk strålningsfysik, Lund; Lunds universitet/Sjukhusfysikerutbildningen

   Author : Madeleine Holm; [2016]
   Keywords : Medicine and Health Sciences;

   Abstract : This work presents the first data from a calculation engine for synchrotron Microbeam Radiation Therapy (MRT) implemented in the EclipseTM Treatment Planning System from Varian Medical Services. The calculation engine constitutes a simple pencil beam algorithm estimating ‘peak’ dose and of Monte Carlo simulated Peak Valley Dose Ratios (PVDRs) that are used to obtain ‘valley’ dose. READ MORE

6. 5. Measurement of absorbed dose to the skin and its relation with microcircular changes in breast cancer radiotherapy

   University essay from Stockholms universitet/Fysikum

   Author : Chahed Yacoub; [2016]
   Keywords : Radiotherapy; Breast; Microcirculation; Skin;

   Abstract : Radiation therapy has been shown to increase local and regional control as well as overall survival with breast cancer, but the vast majority of patients develop acute skin reactions, which are in part related to microvascular changes. These reactions vary between different skin sites. READ MORE
