amplitude

 [am´plĭ-to̳d]
1. largeness, fullness; wideness or breadth of range or extent.
2. in conventional tomography, the motion of the x-ray tube (with the cassette moving in the opposite direction) during the x-ray exposure.

am·pli·tude

(am'pli-tūd),
Largeness; extent; breadth or range.
[L. amplitudo, fr. amplus, large]

amplitude

/am·pli·tude/ (am´plĭ-tldbomacd)
1. largeness, fullness; wideness in range or extent.
2. in a phenomenon that occurs in waves, the maximal deviation of a wave from the baseline.

amplitude of accommodation  amount of accommodative power of the eye.

amplitude

[am′plityo̅o̅d]
Etymology: L, amplus, wide
the width or breadth of range or extent, such as amplitude of accommodation or amplitude of convergence.

amplitude

An MRI term for the strength (height) of a signal; the greater the amplitude of an MRI signal, the larger the number of protons in the image and the brighter it will appear.

amplitude

Cardiac pacing The maximum absolute value attained by an electrical waveform, or any quantity that varies periodically; pacemaker amplitudes express the value of the potential difference in volts or current flow in amperes; pacemaker output pulses have typically averaged 5 volts and 10 milliamps. See Relative fusional vergence.
