How Analyze was Used
“For both patients and volunteers, a number of different MRI images were acquired to construct and validate the respiratory motion models.”

“The roadmap is formed by segmenting structures of interest, such as the four chambers and/or major vessels, from the high resolution scan using the ANALYZE software package … The marching cubes algorithm implemented in VTK [Visualization Toolkit] (Schroeder et al., 1997) is used to extract a surface from the binary images. The high resolution image was also used in the model formation process.”
