Abstract
In one form, the present invention is a method for rapidly resampling a three-dimensional volume of data to permit efficient interactive viewing and visualization of the data is provided in which a set of parallel line segments defining a surface having a constant slope in at least one direction and intersecting the three-dimensional volume are selected and the data is processed at points on the parallel line segments to generate a reformatted image of the data. A corresponding apparatus embodiment is provided. Processing of data can proceed quickly because it is not necessary to check the parallel line segments during processing of the points on the segments to determine whether the points are within a given data volume.

A method for rapidly resampling a three-dimensional volume of data to permit efficient interactive viewing and visualization of the data, the method comprising:
- selecting a set of parallel line segments defining a surface having a constant slope in at least one direction and intersecting the three-dimensional volume, wherein selecting a set of parallel line segments comprises the step of clipping ends of the line segments so that the clipped line segments lie wholly within the three-dimensional volume;
- and
- processing the data by resampling the three-dimensional volume of data at points on the parallel line segments to generate a reformatted image of the data, wherein the processing comprises:
- selecting a sampling function;
- and
- computing the selected sampling of the data at points along the clipped line segments.
A system for rapidly resampling a three-dimensional volume of data for efficient interactive viewing and visualization of the data, said system configured to:
- select a set of parallel line segments defining a surface having a constant slope in at least one direction and intersecting the three-dimensional volume;
- clip ends of the parallel line segments so that the clipped line segments lie wholly within the three-dimensional volume;
- process the data by resampling the three-dimensional volume of data at points on the parallel line segments to generate a reformatted image of the data;
- select a sampling function;
- and
- compute the selected sampling of the data at points along the clipped line segments.
