    Delineation of brain tumours for radiotherapy patients using image segmentation techniques
    Author(s): Yousif Abdallah*

    Background: Precise radiation segmentation of brain tumours is essential for the definition of Gross Tumour Volumes (GTVs). For sensitive GTV detection, the most comprehensive data may be provided by MRI images. This study was conducted to delineate malignant brain tumours in radiotherapy patients using image segmentation techniques. Materials and Methods: MRI images of 10 patients with astrocytoma were used in this study. A new method of watershed-based segmentation techniques was used to segment the GTVs (region of interest, ROI) in T1- and T2-weighted MRI images. These techniques were used to delineate the GTVs morphologically and accurately and were compared with manually delineated GTVs. To analyse the segmentation technique quantitatively, the Dice similarity coefficient, sensitivity and segmentation specificity were calculated. The images were processed with the MATLAB image pr..
