Strålebehandling afhænger i høj grad af indtegning af organer og tumor på medicinske billeder. Disse indtegninger er afgrende for behandlingen. Desværre er disse manuelle indtegninger variation følsomme overfor variation mellem indtegnere. Samtidig er manuelle indtegninger tidskrævende. Denne afhandling dokumenterer arbejde inden for den automatisk definition af organer og tumorer. Specialet indeholder et resume af de tidligere anvendte metoder til automatisk segmentering og 3 artikler, som beskriver segmenteringsalgoritmer indenfor forskellige anvendelsesområder til strålebehandling. Afhandlingen dokumenterer variationen indenfor og imellem manuelle og automatiske segmenteringsmetoder. Den sidste artikel af afhandlingen analyserer forskelle i behandlingsudfald sammenhæng med variation for manuelle indtegninger.Radiation therapy relies in great extent on delineations of tumour and organs on medical images. These delineations are essential for the entire treatment. Unfortunately manual delineations are both prone to variation. At the same time the manual delineation process is time-consuming. This thesis represent a work within the automatic definition of organs and tumours. The thesis includes a summary of the prior methods employed for automatic segmentation and 3 articles describing segmentation algorithms of different areas of application for radiation therapy. Variation within and between manual and automatic segmentation methods is documented in the thesis. The last article of the thesis analyses treatment outcome difference due to manual delineation variation
