1. 1. " Optimization of Margins and Plan Robustness for Proton Therapy of Hodgkin’s Lymphoma"

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Filip Hörberger; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : Purpose/Background: Utilizing proton therapy (PT) for treatment of Hodgkin’s lymphoma (HL) has demonstrated favorable features, particularly a reduced dose to organs at risk (OAR) in comparison with photon radiotherapy. However, there is a coherent complexity with PT including its uncertainties, such as range-uncertainties and set-up variations as protons are highly sensitive to tissue density variations within the beam-path.

3. 2. Evaluation of the treatment planning system decimal ElectronRT and custom-made bolus for FLASH-irradiation

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Mizgin Coskun; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : Introduction: The novel external beam therapy technique using ultra-high dose rates known as FLASH has become known for its normal tissue sparing effect. Currently in Lund, veterinary clinical trials are carried out on canine patients using electrons with ultra- high dose rates. READ MORE

4. 3. Surface Guided Helical Tomotherapy for Total Marrow Irradiation

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Hedda Enocson; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : Background: Total marrow irradiation (TMI) with helical tomotherapy treatment (HT-TMI) can be used as conditioning regimen for leukemia patients prior to stem cell transplantation by radiating the skeletal tissue. To ensure adequate dose coverage a margin is applied to the clinical target volume (CTV), i.e. planning target volume (PTV) margin. READ MORE

5. 4. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Jules Reniaud; [2022]
   Keywords : Technology and Engineering;

   Abstract : Magnetomotive Ultrasound, MMUS, is an imaging modality used to reveal a magnetic contrast agent using an external time-varying inhomogeneous magnetic field. By this, the particles are set in motion, and the motion is detected with ultrasound. READ MORE

6. 5. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Maria Blomstedt; [2022]
   Keywords : Medicine and Health Sciences;

   Abstract : Background: One of the polymer gel dosimeters available today is the N-isopropylamide (NIPAM) polymer gel dosimeter which has a less toxic monomer compared to other polymer gels and the advantage of being able to be manufactured under normal oxygen levels. Polymer gel dosimeters in general are advantageous independent dosimeters to use for verification of new radiation treatment techniques due to its favorable qualities such as very high resolution, 3D coverage, tissue equivalence and independence of energy and incident direction of the radiation beam.
