Abstract: An imaging system apparatus and operating method thereof utilize a volumetric resampling technique with interpolation to determine sample point values on user-defined paths traced through a volumetric image comprising a group of predefined data values, which are themselves samples of a continuous volumetric object. Data values to be displayed are determined from the sample point values using user-selected interpolation and visualization operating modes.

Abstract: A facility is provided for greatly enhancing the rate at which volumetric data is processed by display on a two-dimensional display. Specifically, the volumetric data is first divided into a predetermined number of sub-blocks, in which a predetermined voxel in each sub-block is then transformed into an associated picture element. The sub-blocks and their associated pixels are then supplied to respective processors forming an array of processors. Each processor then completes the transformation of its sub-block as a function of the coordinates of the associated picture element and respective incremental vectors.
