标准摘要
[中文适用范围]: IEC 61391 的这一部分定义了测量实时超声 B-MODE 扫描仪的最大穿透深度和局部动态范围的术语并指定了方法。这些扫描仪使用的传感器类型包括: ?C 机械探头; ?C电子相控阵; ?C线性阵列; ?C 弯曲阵列; ?C 二维数组; ?C 三维扫描探头基于上述类型的组合。所有考虑的扫描仪均基于脉冲回波技术。该测试方法适用于在 1 MHz 至 15 MHz 频率范围内运行的传感器,无论是在基波模式还是在扩展至 15 MHz 的谐波模式下运行。然而,本标准不涵盖 15 MHz 以上谐波模式的测试。注:鼓励模型制造商扩展模型指定的频率范围,以便能够对在 15 MHz 以上的基频和谐波频率下运行的系统进行测试。 [外文原描述]: IEC 61391-2:2010 defines terms and specifies methods for measuring the maximum depth of penetration and the local dynamic range of real time ultrasound B MODE scanners. The types of transducers used with these scanners include: - mechanical probes; - electronic phased arrays; - linear arrays; - curved arrays; - two-dimensional arrays; - three-dimensional scanning probes based on a combination of the above types. All scanners considered are based on pulse-echo techniques. The test methodology is applicable for transducers operating in the 1 MHz to 15 MHz frequency range operating both in fundamental mode and in harmonic modes that extend to 15 MHz. However, testing of harmonic modes above 15 MHz is not covered by this standard.
