I have a dataset of 3D "grayscale" images (medical ultrasound dataset) in the form of cartesian coordinates of each voxel and according grayscale intesity values. I want to convert this data to the 3D image matrix (so that it can be used in matlab programming).
I have seen a similar function but for "plotting" named "pcolor" for "2D" images. I want that the output be a "3D" image "matrix" and I don't want only to visualize tha data, so this function is not useful.
-Do you know whether the matlab image processing toolbox (or file-exchange resources,...) has a function that can perform such conversion?
-If the suitable function does not exist in image processing toolbox, how I can program this conversion using matlab? I think that I must do some sort of interpolation, but I don't know exactly how to do it.
your help and comments are greatly appreciated I am looking forward to receiving responses
