Medical Definition of Aliasing
1.
A pattern of image sampling error in digital systems. Aliasing forces spatial frequency components higher than a critical value (the Nyquist frequency) to be displayed at progressively lower frequencies. Aliasing introduces an undesirable moire pattern when the spatial frequency of the signal exceeds the sampling rate in a digitiser.
