I am trying to obtain the centerline from a model.
First, I imported my dataset (It is a nrrd file created in Fiji from a ome tiff file from a lightsheet stack, as previously somebody recommended in this forum). Here, the first problem arrived: I had to downsample my dataset (originally 2540x1956x454, 16 bits) to 1000x700x227, 8 bits, because otherwise Slicer was crashing.
Then, I applied a median filter and threshold segmentation to create the model. I use the VMTK centerline calculation module, so I selected the feducials for the starting and endpoints. I clicked in Preview and the centerline was nicely calculated. However, in an attempt to extract it either as a binary image or a point list, I clicked in Start and Slicer crashed again.
Does anybody has any suggestion for extracting the centerline or any other alternative module to calculate and export the centerline of a model?
I really appreciate your help.
