  1. 1. Surface Guided Helical Tomotherapy for Total Marrow Irradiation

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Hedda Enocson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 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. LÄS MER

  3. 2. Can Surface Scanning Improve the Workflow of Elekta Linac Treatments?

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Anna Arousell; Ylva Engdahl; [2019]
    Nyckelord :Elekta Linac; Elekta VersaHD; Elekta Infinity; C-RAD; Catalyst; radiotherapy; surface scanning; workflow analysis;

    Sammanfattning : The aim of the project was to compare the workflow for an Elekta Linac with and without the surfacescanning system Catalyst and describe pros and cons with both workflows. The findings in the reportcan be used as decision support in development of Elekta products and workflow improvements. LÄS MER

  4. 3. Validation of Catalyst HD™ positioning performance using a deformable phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Beatrice Akinrimisi; [2019]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Aim: The overall purpose for this master thesis was to evaluate the deformable algorithm of the optical surface scanning system Catalyst HDTM . The aim was to develop a method to evaluate the non-rigid registration algorithm using a deformable phantom and with it investigate the positioning accuracy of the depth calculation. LÄS MER

  5. 4. Evaluation of astructured-light 3D-scanner for respiratory gating in PET/CT in a clinical setting

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Elin Wessel; [2018]
    Nyckelord :;

    Sammanfattning : In this study a structured light prototype device was evaluated for the possible use as a respiratory gating device in PET/CT. The device functions by measuring the movement in the vertical direction of the obtained 3D-surface of the chest and abdomen with the breathing. LÄS MER

  7. 5. A comparison of surface based and laser based setup for rectal cancer patients in radiotherapy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Sandra Hamid; [2017]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : 60 00 cancerfall rapporteras in varje år till socialstyrelsen men där numera fler än hälften botas. Detta eftersom vi blir skickligare inom området och nya behandlingstekniker utvecklas. Rektalcancer, även kallat ändtarmscancer är en cancerform som ökat under de senaste decennierna. LÄS MER
