IEC 61391-1-ed.1.0

Annotation of standard text IEC 61391-1-ed.1.0 :

Describes methods of calibrating the spatial measurement facilities and point-spread function of ultrasonic imaging equipment in the ultrasonic frequency range 0,5 MHz to 15 MHz. This standard is relevant for ultrasonic scanners based on the pulse echo principle of the types listed below: - mechanical sector scanners; - electronic phased-array sector scanners; - electronic linear-array scanners; - electronic curved-array sector scanners; - water bath scanners based on any of the above four scanning mechanisms; - 3D-volume reconstruction systems. Decrit des methodes detalonnage des moyens de mesure spatiaux et de la fonction de dispersion ponctuelle dequipements dimagerie a ultrasons, dans la gamme des frequences ultrasoniques setendant de 0,5 MHz a 15 MHz. La norme sapplique aux scanners ultrasoniques bases sur le principe dimpulsion et echo des types suivants: - scanners sectoriels a balayage mecanique; - scanners sectoriels electroniques a reseau de phase; - scanners electroniques a reseau lineaire; - scanners sectoriels electroniques a reseau courbe; - scanners a bain deau, base sur lun des quatre mecanismes de balayage precedents; - systemes de reconstruction de volume en 3D.
