Full Description
This document specifies requirements and methods for periodic testing of the quality of
diagnostic medical ultrasound systems with linear array, curved linear array, single element,
annular array, phased array, matrix linear array transducers and two-dimensional arrays.
Image interpretation and measurement workstations are included. Usually, "periodic testing" is
referred to here as "quality control". This document represents a minimum set of such tests
intended for frequent users of medical ultrasound systems, for quality control professionals in
their organization, or those hired from other quality-control and/or service-provider
organizations. System-manufacturing and repair companies might well employ other or
additional tests. The tests are defined in three levels, with the simplest and most costeffective
performed most frequently, similarly to [1]. More complete tests for acceptance
testing and for assessment at times of particular importance or concern are specified in
IEC 61391-1, IEC 61391-2 and IEC TS 62791 [15]. These more complete tests are
categorized as performance evaluation, rather than quality control or frequent periodic testing.
This document also defines terms and specifies methods for measuring (for quality maintenance or quality control) the maximum relative depth of penetration of real-time ultrasound B-MODE scanners, though this penetration measure is listed as less frequently applied.
Frequent distance-measurement accuracy tests are recommended only for certain classes of position encoding that are not now known to be highly stable and without bias.
The types of transducers used with these scanners include:
All scanners considered include basic pulse-echo techniques. The failures to be detected by the recommended pulse-echo tests also will affect the operation of other modes, such as colour-flow, harmonic-, elasticity- and compound imaging. The test methodology is applicable for transducers operating in the 1 MHz to 17 MHz frequency range and could be made applicable up to 40 MHz, if the depth of penetration were allowed to be relative, rather than absolute, and phantom stability were verified [15]. Image-uniformity QC is applicable to transducers operating in the 1 MHz to 40 MHz frequency range as the requirements for phantoms are not stringent.
NOTE Phantom manufacturers are encouraged to extend the frequency range to which phantoms are specified to enable relative depth-of-penetration tests of systems operating at fundamental and harmonic frequencies above 17 MHz.
