Samenvatting

Inhoud – 1 Inleiding – 2 EPID-beeldvorming – 3 kV-beeldvorming – 4 Beeldkwaliteit – 5 Controle van de positionering met EPID’s en kV-beeldvorming – 6 Onderverdeling van afwijkingen – 7 Correctieprotocollen – 8 Klinische toepassingen CBCT – 9 Overige ontwikkelingen binnen IGRT – In dit hoofdstuk worden de mogelijkheden en de klinische toepassingen van beeldgestuurde radiotherapie (Image Guided Radiotherapy – IGRT) beschreven. Hierbij komen de techniek en de toepassingen van Electronic Portal Imaging Devices (EPID’s), planaire kV-opnamen en cone-beam-CT (CBCT) aan bod. Ook wordt beschreven hoe door de toepassing van positioneringsprotocollen de nauwkeurigheid van patiëntpositionering verbeterd kan worden. Dit hoofdstuk zal inzicht geven in: de wijze waarop de diverse beelden tot stand komen; artefacten die zichtbaar kunnen zijn in de beelden en de oorzaak ervan; het onderscheid tussen systematische en random positioneringsfouten en het effect daarvan op planningsmarges; verkleining van positioneringsfouten door gebruik van offline en online positioneringsprotocollen; voorbeelden van klinische toepassingen van EPID’s, planaire kV-opnamen en CBCT.
