Anotace textu normy IEC/TR 61390-ed.2.0 :
IEC TR 61390:2022 describes representative methods of measuring the performance of complete real-time medical ultrasonic imaging equipment in the frequency range 0,5 MHz to 23 MHz. This document is relevant for real-time ultrasonic scanners based on the pulse-echo principle, for the types listed below: - mechanical sector scanner; - electronic phased array sector scanner; - electronic linear array scanner; -electronic curved array sector scanner; - water-bath scanner based on any of the above four scanning mechanisms; - plane-wave/fast imaging scanners; - combination of several of the above methods (e.g. a linear array phased at the edge to produce a sector there to enlarge the field of view. The methods described are based on evaluation of: - sonograms obtained by scanning of tissue mimicking objects (phantoms); - sonograms obtained by scanning of artificial, low- or highly reflective targets in suitable environments; - parameters of the ultrasound field transmitted by the measured scanner. This document does not relate to methods for measuring electrical parameters of the scanner’s electronic systems. IEC TR 61390:2022 cancels and replaces the first edition published in 1996. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Several additional phantom designs are included in the main body of the document; b) Several additional transducer types are included in the Scope; c) Methods of analysis are presented in new Annex B.
