Hello!

I have segmentented a series of consecutive 2D MRI images and stored the masks in a cell array. Now I would like to be able to visualize a 3D representation of the volume segmentated.

Each mask contains the area of the slice that I need to visualize. I also know the value of the spacing between the slices. I don´t know how I could achieve this so any help is apreciated.

Thank you in advance.

I don't know why you chose to use a cell array. Are you just trying to make it more difficult?

Have you tried volshow?

I used a cell array because I needed it that way for previous operations, but I could now change it to something else if that makes it easier.

The data sotored in the array are just binary masks which contains the ROI that I´m interested in. Would volshow work with that kind of data? I have tried it and I could not make it work, but maybe I am not using the function correctly.
