  1. 1. Independent validation of a system for real-time localization of the prostate during motion tracking radiotherapy

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen

    Författare :Klara Stefansson; [2024]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. LÄS MER

  3. 2. Analysis of bladder cancer treatment plans generated for online adaptive radiotherapy and validation of an integrated independent dose calculation software

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Daria Badika; [2020]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: In 2019 Varian EthosTM linear accelerator (Varian Medical Systems, CA, USA) with integrated artificial intelligence (AI) was installed at Herlev Hospital, Copenhagen, Denmark, enabling online adaptive radiotherapy (oART) e.g for bladder cancer patients with a large margin reduction.

  4. 3. Clinical Investigations of Image Guided Radiation Therapy for Prostate Cancer with an On-Board Imager

    Uppsats för yrkesexamina på grundnivå, Medicinsk strålningsfysik (tills m KI)

    Författare :Maria Lindskog; [2008]
    Nyckelord :Cone-beam CT; IGRT; Adaptive radiotherapy;

    Sammanfattning : The daily uncertainty concerning tumor localization is one of the major problems during the course of radiation therapy. Image guided-radiation therapy (IGRT) can be used to improve the localization and adjustment of the planning target volume. LÄS MER

  5. 4. Evaluation of Geometric Accuracy and Image Quality of an On-Board Imager (OBI)

    Uppsats för yrkesexamina på grundnivå, Medicinsk strålningsfysik (tills m KI)

    Författare :Milos Djordjevic; [2007]
    Nyckelord :Image-guided radiotherapy; Cone-beam CT; OBI; Quality Assurance;

    Sammanfattning : In this project several tests were performed to evaluate the performance of an On-Board Imager® (OBI) mounted on a clinical linear accelerator. The measurements were divided into three parts; geometric accuracy, image registration and couch shift accuracy, and image quality. LÄS MER

  7. 5. Evaluation of the Elekta Synergy concept for patient positioning in image guided radiotherapy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johan Renström; [2006]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : Introduction: The Elekta Synergy machine for external beam radiation therapy is equipped with an x-ray tube for on-line kV imaging and correction of the patient setup. The system can provide both 2D and 3D data for image guided radiotherapy (IGRT). LÄS MER
