I have a sequence of uniformly spaced spatially separated MRI images along the Z-axis(along the body)(i.e. each image is a slice along the z axis and I have many of those images at a uniform separation) and I would like to know if there is a software(preferably open source but not limited to) that could combine them together to give me a 3D solid representation of the imaged regions.
I've successfully used 3D Slicer to look at MRI images. Also have a look at the Wikipedia page on the subject of open source health care software. It has a section on visualization.
