A process for creating custom fixtures for parts that are to be CNC lathe machined is fully automatic and requires no human interaction. The customer's CAD file is computer analyzed to determine whether the part's dimensions fit within an available CNC lathe turning center for forming out of a cylindrical stock bar. The longitudinal axis is identified, and a set of tool paths is developed for cutting the part from two respective directions. A corresponding tool path is developed for CNC lathe cutting a bushing, preferably from the same bar stock, which generally represents the negative space around circular cross-sections of the part, in monotonically increasing diameters from the first end of the part. The bushing is then used to hold the part in the chuck during machining the second end of the part from the opposite direction.

Automated bushing construction for lathe turning

A computing system and method for generating, displaying and manipulating synthetic 2D and 3D brain tissue viability images and associated metrics from multiple perfusion maps derived from CT or other imaging system input image datasets. Stored linguistic tissue classification rules characterizing infarct, ischemic and/or normal or other tissue classes as a function of one or more perfusion parameters are used. The perfusion maps are normalized to normal brain tissue regions. Elements of the input image dataset are classified into one of the tissue classes as a function of the normalized perfusion maps and the classification rules. The classification includes ranking each of the plurality of tissue classes for elements of the input image dataset, and assigning one of the classes to elements of the dataset as a function of the ranks.
