11. Surface Guided Helical Tomotherapy for Total Marrow Irradiation
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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

12. Increased Displacement in Magnetomotive Ultrasound Imaging by Adding a Homogeneous Magnetic Field
University essay from Lunds universitet/Avdelningen för Biomedicinsk teknikAbstract : 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

13. Polymer gel dosimetry - Using MRI-readout, simplified relatively non-toxic mixing procedure tested on FLASH
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : 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.

14. Preparations for photon external beam radiotherapy treatment planning of small animals
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. READ MORE

15. Breathing Effects in Proton Scanning for Hodgkin's Lymphoma
University essay from Lunds universitet/SjukhusfysikerutbildningenAbstract : Purpose/Background Proton beam scanning (PBS) for mediastinal Hodgkin's Lymphoma (HL) is limited when treating in free-breathing (FB) due to breathing motion in the thoracic region. Tumour motion and the time structure of the beam delivery will cause interplay and dose blurring effects, resulting in discrepancies of dose in the planned dose distribution both inside and at the edges of tumour volume (TV).
