3 Terms and definitions
Replace the first two paragraphs with the following new paragraph:
For the purposes of this document, the terms and definitions given in IEC 60050-801:1994,
IEC 60050-802:2011, IEC 62127-1:2007 and the following apply. See also related
International Standards, Technical Specifications and Technical Reports for definitions and
explanations [1] [2] [3] [4] [34] [35] [36] [37] [38] [39].
3.25
point-spread function
PSF
Add the following new sentence at the end of the NOTE:
The problem is solved by PSF mapping – see Annex D.
Add the following new terms and definitions to Clause 3, starting with 3.45.
3.45
accuracy
closeness of agreement between a test result and the accepted reference value
[SOURCE: ISO 5725-1:1994, 3.6]
3.46
axial resolution in a PSF-map
twice the Half-Width-at-Half-Maximum (HWHM) of a function’s trace created from a set of
increasing pixel values, commencing near zero and terminating at the first maximum value
(centre of the PSF) and representing the leading edge of the echo signal from a point reflector
located on the main beam axis
Note 1 to entry: The axial resolution in a PSF map differs from the axial resolution specified by 3.5. It is used
for the PSF-mapping only to simplify the data acquisition.
Note 2 to entry: A detailed explanation of the axial resolution in the PSF-map measuring method is in D.6.1.4.
Note 3 to entry: The axial resolution mainly depends on the ultrasound frequency used, not on sonograph
construction.
Note 4 to entry: Axial resolution in a PSF-map is expressed in metres.
3.47
brightness
luminance as perceived by the human visual system
[SOURCE: IEC 62563-1:2009, 3.1.2]
3.48
contrast
C
ratio of the difference of the luminance of two image areas, L − L , divided by the average of
1 2
the two luminance values:
C = 2 (L − L )/(L + L )
1 2 1 2

3.49
dynamic imaging
real-time imaging
imaging with a frame rate that is high enough to observe moving structures in apparently
continuous motion
3.50
elevational resolution in a PSF-map
difference of point-reflector displacements in passing through the scanning plane in an
elevational direction, which result in decreases of MER of −6 dB compared to the MER-value
in the beam centre
Note 1 to entry: The elevational resolution in a PSF-map differs from the elevational resolution specified by
3.12. It is used for the PSF-mapping only to simplify the data acquisition.
Note 2 to entry: Detailed explanation of the method is in D.6.1.3.
Note 3 to entry: Elevational resolution in a PSF-map is expressed in metres.
3.51
overall gain
G
o
basic level of gain that is uniform for the whole scan area but modified by TGC relative to the
depth of the scan
3.52
profile line
set of pixel values ordered along an abscissa according to the sequence during their
acquisition
3.53
lateral resolution in a PSF-map
Full-Width at Half-Maximum (FWHM) of the PSF, measured in a lateral direction
Note 1 to entry: The lateral resolution in a PSF-map differs from the lateral resolution specified by 3.17. It is
used for the PSF-mapping only to simplify the data acquisition.
Note 2 to entry: Detailed explanation of the method is in D.6.1.2.
Note 3 to entry: Lateral resolution in a PSF-map is expressed in metres.
3.54
measuring grid
matrix of points specified by Cartesian coordinates x and z defined in a plane parallel to the
i j
scanning plane
Note 1 to entry: Each point determines the position (x ,z ) in which individual measurement of PSF is performed.
i j
Note 2 to entry: The step ∆x is defined as an increment x – x in the lateral direction. The step ∆z is defined as
i+1 i
an increment z – z in the axial direction.
j+1 j
3.55
performance evaluation
tests performed to assess specific absolute performance of the object tested
Note 1 to entry: Typical times for ultrasound-system performance evaluation are at pre-purchase evaluation,
new- and repaired-system acceptance testing, at time of performance difficulties, and at end-of-useful-life
evaluations.

3.56
precision
closeness of agreement between independent test results obtained under stipulated
conditions
[SOURCE: ISO 5725-1:1994, 3.12]
3.57
scanning window
area on the surface of the test tank dedicated for transducer application to obtain a suitable
sonogram of the target
Note 1 to entry: It is important that the scanning window be covered by flexible foil made of material with similar
acoustic properties to the working liquid to avoid ultrasound field reflections and absorption.
Note 2 to entry: The foil flexibility should assure proper acoustical contact of any type of curved transducer.
Note 3 to entry: It is important that the foil covering the scanning-window be tough enough to prevent its damage
during coupling the measured transducer to the scanning window, to prevent resultant leakage of working liquid
from the measuring tank.
Note 4 to entry: The scanning window has the identical function as the test object scanning surface in the
case of tissue-mimicking test objects (see 3.34).
3.58
side-lobe signal
echo signal generated by ultrasound signal transmitted/received in a direction different from
the central axis of the transducer
3.59
test tank
tank designed to be suitable for providing specified kind of tests, which is filled with a
working liquid and equipped with scanning window(s)
