Time-intensity plots and other graphs can also be generated for single or multiple regions. All defined regions can be saved to hard disk as .roi files and can be recalled later. Color coded images of all physiologic parameters are generated and may be saved to disk. The Image Manipulation modules are used for processing and manipulating image data. Included are various segmentation methods, interactive image editors, and automated analysis libraries.
Segmentation makes manual image segmentation as flexible as possible.
One can use 2-D Segmentation to distinguish particular structures from others within the same slice, such as the right vs. the left chambers of the heart. Segmentation is accomplished by altering the gray levels of structures so as to uniquely identify them. Complex image analyses can be performed by constructing a sequence of simpler image processing and analysis functions. By using MSBI or CVI before Surface Render or Volume Render, one reduces the stair step effect associated with thick slices. Vessel Segmentation can be used to segment connected vessels, such as airways or other major conduits, from three dimensional images.
