  1. 1. Automation of robust Pareto front-based radiotherapy treatment planning for prostate cancer patients

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Niklas Eliasson; [2019]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose/objective The main objective was to create a software that automates the process of creating treatment plans used for Pareto front-based dose planning for prostate cancer patients. A second objective/purpose was to add a robustness test to this program to evaluate the effect of prostate movements on the treatment plans. LÄS MER

  2. 2. DICOM Second Generation RT : An Analysis of New Radiation Concepts by way of First-Second Generation Conversion

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :David Holst; [2019]
    Nyckelord :;

    Sammanfattning : The current DICOM communication standard for radiotherapy is outdated and has serious design issues. A new version of the standard, known as DICOM 2nd generation for Radiotherapy, has been introduced and this thesis examines new concepts relating to radiation delivery. LÄS MER

  3. 3. The Potential of Intra-fraction Monitoring of Patient Anatomy Using a Parameterized Motion Model

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Maya Staneva; [2019]
    Nyckelord :;

    Sammanfattning : Radiotherapy aims to strike a tumour with high accuracy, but anatomic changes and internal organ motion introduce uncertainties and therefore large margins are conventionally used to compensate for this. The MR-Linac will enable target tracking prior to and during treatment which will make daily adjustments of a treatment plan possible. LÄS MER

  4. 4. Deep Learning Based Multi-Label Classification of Radiotherapy Target Volumes for Prostate Cancer

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Lina Welander; [2019]
    Nyckelord :Multi-label classification; MIQA; INCA; Deep neural network;

    Sammanfattning : An initiative to standardize the nomenclature in Sweden started in 2016 along with the creation of the local database Medical Information Quality Archive (MIQA) and a national radiotherapy register on Information Network for CAncercare (INCA). A problem of identifying the clinical tumor volume (CTV) structures and prescribed dose arose when the consecutive number, which is added to the CTV-name, was made inconsistently in MIQA and INCA.

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

    Kandidat-uppsats, KTH/Medicinteknik och hälsosystem; 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
