IEC/TS 62558 1st Edition, March 1, 2011 Ultrasonics – Real-time pulse-echo scanners – Phantom with cylindrical, artificial cysts in tissue-mimicking material and method for evaluation and periodic testing of 3D-distributions of void-detectability ratio (VDR)
More info
Description / Abstract:
This technical specification specifies essential characteristics
of a phantom and method for the measurement of void-detectability
ratio for medical ultrasound systems and related transducers. It is
restricted to the aspect of long-term reproducibility of testing
results.
This technical specification establishes:
– important characteristics and requirements for a TMM 3D artificial cyst phantom using anechoic voids;
– a design example of a 3D artificial cyst phantom, the necessary test equipment and use of relevant computer software algorithms.
This technical specification is currently applicable for linear array transducers. A uniformity test prior to void-detectability ratio (VDR) measurement is recommended.
NOTE The basic concept of the 3D artificial-cyst phantom may also be valid for other types of ultrasound transducers; however there is a need for further verification (see Annex D).
