Methods of measuring the performance of ultrasonic pulse-echo diagnostic equipment

Edition date: 1986-10-30
In Force
Available languages: English, French
Summary: Defines parameters and outlines test methods for measuring performance of pulse-echo medical diagnostic systems that employ single-element transducers and operate in the 0.5 MHz to 25 MHz acoustic frequency range. Provides a generally acceptable basis for measuring and reporting the principal performance parameters of complete diagnostic systems. The performance parameters specified, and the corresponding methods of measurement, have been chosen in order to provide a basis for comparison between similar apparatus of different makes intended for the same kind of diagnostic application. The set of results and values obtained from the use of the recommended methods will provide useful criteria for predicting the performance of equipment in appropriate diagnostic applications. In order that the recommendations should be suitable for general applications, methods have been specified which do not require unusual and expensive equipment for their implementation. Where one basic diagnostic system accommodates more than one option in respect of a particular system component, such as the transducer, it is intended that, wherever appropriate, each option be regarded as a separate system. Has the status of a technical report.

Définit des paramètres et expose des méthodes pour mesurer les caractéristiques fonctionnelles des appareils de diagnostic médical à impulsions ultrasonores qui utilisent des transducteurs à un seul élément et sont conçus pour fonctionner dans la plage de fréquences acoustiques qui s'étend de 0,5 MHz à 25 MHz. Etablit des bases acceptées de manière générale pour mesurer et déterminer les paramètres principaux de fonctionnement des équipements complets servant au diagnostic. Les méthodes de mesure et les paramètres de fonctionnement spécifiés ont été choisis de manière à établir une base de comparaison entre des appareils semblables de constructions différentes et destinés à des diagnostics de même nature. Les séries de résultats et de valeurs obtenues par les méthodes recommandées doivent fournir des critères utiles permettant de prévoir le comportement du matériel dans des applications diagnostiques appropriées. Pour que ces recommandations puissent être d'une application générale, on a prescrit des méthodes dont la mise en oeuvre n'exige pas de matériel exceptionnel ou coûteux. Lorsqu'un appareillage de diagnostic de base est susceptible de recevoir plusieurs versions d'un élément constitutif particulier au système, comme le transducteur par exemple, chaque version est à considérer comme un système séparé. Cette publication a le statut d'un rapport.
