1. Acquisition Error Includes errors introduced by the ultrasound system
electronics relating to signal acquisition, signal conversion, and signal
processing for display. Additionally, computational and display errors are
introduced by the generation of the pixel scale factor, application of that factor
to the caliper positions on the screen, and the measurement display.
2. Algorithmic Error The error introduced by measurements, which are input to
higher order calculations. This error is associated with floating-point versus
integer-type math, which is subject to errors introduced by rounding versus
truncating results for display of a given level of significant digit in the
calculation.
