I have a question, I want to remove the table of dicom files. For that, I do an “open” to remove the table and an “close” to fill the image as a mask. The problem comes with “close” to fill in the image with a big kernel, the program becomes very slow and it sometimes crashes. But If I remove this step some structures are missing with the erosion of the “open”. So I need a way to make the mask filled.
Is there any filter that can help me with that?. I have tried to make subregions but as one side of the table is very close to the body some areas cannot be discarded if I do that. So I need to do the “open” to the whole image.
The image is a 3d dicom.
What I would like to obtain is this mask of the whole image but it is not feasible to make morphology for that.
