Validation Techniques for Quantitative Brain Tumors Measurements

Abstract: Quantitative measurements of tumor volume becomes more realistic with the use of imaging- particularly specially when the tumor have non-ellipsoidal morphology, which remains subtle, irregular and difficult to assess by visual metric and clinical examination. The quantitative measurements depend strongly on the accuracy of the segmentation technique. The validity of brain tumor segmentation methods is an important issue in medical imaging because it has a direct impact on many applications such as surgical pla… Show more

“…Ho et al proposed a region competition method which modulates the propagation term with a signed local statistical force to reach a stable state (Ho et al, 2002 ). Salman et al examined the seeded region growing and active contour to be compared against experts' manual segmentations (Salman et al, 2012 ). Sato et al proposed a Sobel gradient magnitude-based region growing algorithm which solves the partial volume effect problem (Sato et al, 2000 ).…”

“…We improve our previous work [10] PC based software package implemented using three programming development environment, as VTK [18], ITK [20] and Visual C++, to segment, visualize and calculate the tumor volume at different instants of tumor growing or shrinking. Figure 2 shows the result of tumor segmentation using T-RG and MRGM.…”

“…Segmentation of ROI in volumetric medical images is still a challenging problem, and solutions usually have been based on either model-based deformation of templates or intensity thresholding such as region growing method [6,7]. Recent studies prove that the region growing is an effective approach and less computation intensive for image segmentation especially for the homogenous regions [8,9,10,7,11]. The primary disadvantage of region growing method is the partial volume effect [12,13].…”
