Here is some code illustrating how to use bwboundaries to get X-Y polygon vertices that work better for mask creation via createMask or poly2mask (which createMask calls). The idea is to get a polygon that includes the centers of the desired mask pixels inside the polygon instead of along its edges.

Select the Subsystem block and on the Subsystem tab, in the Mask group,click Create Mask. Step 2: Define the Mask The Mask Editor contains four tabs that enable you to define the block mask and customize the dialog box for the mask. For detailed information on each pane, see Mask Editor Overview.

BW = createMask (rtContours,ROIindex,Spatial) returns the 3-D logical mask BW, a voxel representation of the ROI specified by ROIindex, in the dicomContours object, rtContours. ROIindex specifies the contour in rtContours to be densified. Spatial specifies location, resolution, and orientation of the 3-D data. There can be a problem if MATLAB decides to use the masking scheme when you want index addressing but such situations are rare. Creating and manipulating Matrixes To use the indexing ideas effectively you need to be able to create 'mask' matrices efficiently, and manipulate arrays. This requires the use of functions that you may not have used before.
