  1. 1. Machine learning and augmented data for automated treatment planning in complex external beam radiation therapy

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Michael Lempart; [2019]
    Nyckelord :Machine Learning; Deep Learning; Data Augmentation; Treatment Planning; External Beam Radiation Therapy;

    Sammanfattning : External beam radiation therapy is currently one of the most commonly used modalities for treating cancer. With the rise of new technologies and increasing computational power, machine learning, deep learning and artificial intelligence applications used for classification and regression problems have begun to find their way into the field of radiation oncology.

  3. 2. Detectability of fiducial markers in an MRI-only radiotherapy treatment workflow for prostate

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Sevgi Emin; [2017]
    Nyckelord :prostate cancer; fiducial markers; CT; MRI; MRI-only workflow; Physics and Astronomy;

    Sammanfattning : In a conventional prostate cancer radiotherapy treatment workflow, computed tomography (CT) and magnetic resonance imaging (MRI) are used for radiotherapy treatment planning and target delineation. MRI is necessary in the process due to better soft tissue contrast compared to CT-images. LÄS MER

  5. 4. Flattening filter free volumetric modulated arc therapy for extreme hypofractionation of prostate cancer - Decreasing the treatment time and reducing the impact of prostate motion

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen; Lunds universitet/Medicinsk strålningsfysik, Lund

    Författare :Minna Ahlström; [2015]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: This work examined the feasibility of flattening filter free (FFF) volumetric modulated arc therapy (VMAT) for extreme hypofractionation of prostate cancer. The aim was to investigate the potential gain in treatment time per fraction for extreme hypofractionation of prostate cancer, while preserving or improving the treatment plan quality and radiation delivery quality.

  7. 5. An Evaluation of Kilo Voltage Image Quality Produced by an On-Board Imager System

    Kandidat-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Tina Mobini; [2015]
    Nyckelord :Key Words: Exposure factors; Tube Voltage; Tube current; Contrast; Exponeringsfaktorer; Rörspänning; Rörström; Kontrast;

    Sammanfattning : Syfte: Syftet med detta projekt var att utvärdera kvaliteten på de digitala röntgenbilder som genereras med en On-Board imager® (OBI), monterad på en medicinsk linjäraccelerator på radioterapiavdelningen på Karolinska Universitetssjukhuset. Dessa kilovoltbilder används för att verifiera patientens position på behandlingsbordet, inför behandling, för att reducera risken att friskvävnad bestrålas i onödan. LÄS MER
