| amplitude | 1. State of being ample; extent of surface or space; largeness of dimensions; size. "The cathedral of Lincoln . . . Is a magnificent structure, proportionable to the amplitude of the diocese." (Fuller) 2. Largeness, in a figurative sense; breadth; abundance; fullness. Of extent of capacity or intellectual powers. "Amplitude of mind." . "Amplitude of comprehension." . Of extent of means or resources. "Amplitude of reward." . 3. <astronomy> The arc of the horizon between the true east or west point and the center of the sun, or a star, at its rising or setting. At the rising, the amplitude is eastern or ortive: at the setting, it is western, occiduous, or occasive. It is also northern or southern, when north or south of the equator. The arc of the horizon between the true east or west point and the foot of the vertical circle passing through any star or object. 4. The horizontal line which measures the distance to which a projectile is thrown; the range. 5. <physics> The extent of a movement measured from the starting point or position of equilibrium; applied especially to vibratory movements. 6. <mathematics> An angle upon which the value of some function depends; a term used more especially in connection with elliptic functions. Magnetic amplitude, the angular distance of a heavenly body, when on the horizon, from the magnetic east or west point as indicated by the compass. The difference between the magnetic and the true or astronomical amplitude (see 3 above) is the "variation of the compass." Origin: L. Amplitudo, fr. Amplus: cf. F. Amplitude. See Ample.

| amplitude of accommodation | The difference in refractivity of the eye at rest and when fully accommodated. (05 Mar 2000) |
| amplitude of convergence | The distance between the near point and far point of convergence. Synonym: range of convergence. (05 Mar 2000) |
| amplitude of pulse | See: average pulse magnitude, peak magnitude. (05 Mar 2000) |
| phase-amplitude contrast | <microscopy> The separation and recombination of direct vs. Diffracted rays in a light microscope adjusted to Kohler illumination. at the lower focal plane of the condenser there is an annular diaphragm with an opaque central stop. Through this diaphragm rays are focused as a hollow cone onto the specimen. In the back focal plane of the objective there is a conjugate annular diaphragm (phase plate). If here the undiffracted rays are retarded (by a transparent film of proper thickness on the annulus of the phase plate), bright contrast results. If, instead, the phase-delay film is on the central spot, dark contrast results. With either a bright or a dark-contrast phase plate, the annulus is usually coated with a partially absorbing (very thin) film of silver (Zernike method) or carbon soot (Wilska method) to reduce the higher amplitude (intensity) of the undiffracted rays.

| minimal amplitude nystagmus | Nystagmus of so small an amplitude that it is not detected by the usual clinical tests. Synonym: minimal amplitude nystagmus. Origin: micro-+ G. Nystagmos, a nodding (05 Mar 2000) |
| half amplitude pulse duration | The time, in milliseconds, required for a wave form to reach half of its full magnitude. (05 Mar 2000) |
| tidal amplitude | The magnitude of the difference in elevation between low and high tides at a particular point in a body of water. (09 Oct 1997) |
| atrial echo | Electrical reactivation of the atrium by a retrograde impulse returning from the A-V node while the antegrade impulse continues to the ventricle; characterised electrocardiographically, by a pair of P waves enclosing a QRS complex, the second P wave being inverted, indicating that it is the reverse (the retrograde pathway) of the pathway of the first P wave (the antegrade pathway).

| spin echo | A commonly used technique to recover T2 relaxation signals in magnetic resonance imaging, by using a 180 |
| nodus sinuatrialis echo | A postectopic sinus beat occurring earlier than would be expected from the preceding sinus node discharge interval; i.e., the interval following a premature beat of supraventricular origin is less than the ordinary cycle length between sinus beats, whereas ordinarily the interval would be expected to exceed cycle length. (05 Mar 2000) |
| echo | Origin: L. Echo, Gr. Echo, sound, akin to, sound, noise; cf. Skr. Va to sound, bellow; perh. Akin to E. Voice: cf. F. Echo. 1. A sound reflected from an opposing surface and repeated to the ear of a listener; repercussion of sound; repetition of a sound. "The babbling echo mocks the hounds." (Shak) "The woods shall answer, and the echo ring." (Pope) 2. Sympathetic recognition; response; answer. "Fame is the echo of actions, resounding them." (Fuller) "Many kind, and sincere speeches found an echo in his heart." (R. L. Stevenson) 3. A wood or mountain nymph, regarded as repeating, and causing the reverberation of them. "Sweet Echo, sweetest nymph, that liv'st unseen Within thy airy shell." (Milton) A nymph, the daughter of Air and Earth, who, for love of Narcissus, pined away until nothing was left of her but her voice. "Compelled me to awake the courteous Echo To give me answer from her mossy couch." (Milton) Echo organ, a stop upon a harpsichord contrived for producing the soft effect of distant sound. To applaud to the echo, to give loud and continuous applause. "I would applaud thee to the very echo, That should applaud again." (Shak) Source: Websters Dictionary (01 Mar 1998) |
| echo beat | Extrasystole produced by the return of an impulse in the heart retrograde to a focus near its origin which then returns antegradely to produce a second depolorization. (05 Mar 2000) |
| echo-free | The property of appearing echo-free or without echoes on a sonographic image; a clear cyst appears anechoic. See: transonic. Synonym: echo-free. Origin: G. An-priv. + echo + ic (05 Mar 2000) |
| echo planar | A method of magnetic resonance imaging that allows rapid image acquisition during free induction decay, using technically difficult rapidly oscillating radiofrequency gradients. (05 Mar 2000) |
