Reading and displaying DICOM RT structure based on Matlab / 中国医学装备

ABSTRACT

Objective:To design a software to read and display CT and RT structure and draw a new contour without treatment planning system (TPS).Methods: In order to display the contour information drawn by doctors, the first step was to match CT images and RT structure then the same screen rendering of CT and RT structures could be applied. In order to add contour in RT structure obtaining the coordinates interactively, connecting coordinate points were the essential steps. Then a unique identity was given in the area of that contour to ensure its unique results. Results: The software successfully read and displayed CT and RT structures and drew a new contour without TPS.Conclusion: In this study, the software establishes a basis to improve the precision of the radiotherapy dose.
