Fig. 5From: Enhancing the stability of CT radiomics across different volume of interest sizes using parametric feature maps: a phantom studyExemplary parametric maps. The original computed tomography scan of the phantom is shown in the left upper corner (a). The exemplary maps represent the quantity of the respective feature. The higher the feature quantity for a voxel, the brighter the voxel appears on the map. The map of GLSZM small area emphasis (f) illustrates that the feature quantity of the background is almost similar to the body of the phantom. In the maps of entropy (b), uniformity (c), GLCM IDMN (d), and GLRLM run percentage (e), lines appear in the extension of edges and interfaces of the phantom. A high signal in the background can also be observedBack to article page
