ABSTRACT:
A method and apparatus that provide topologically consistent visual displays of an internal characteristic of a physical object. A measured signal pattern is generated, which describes how the characteristic varies spatially within the physical object. The signal pattern and a threshold value are used to generate a piecewise polygonal approximation, descriptive of the internal characteristic, that is topologically consistent with the internal characteristic. The polygonal approximation is used to generate and display an image representative of the internal characteristic.
