適用范圍：This part of IEC 61391 defines terms and specifies methods for measuring the maximumdepth of penetration and the local dynamic range of real-time ultrasound B-MODEscanners. 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 isapplicable for transducers operating in the 1 MHz to 15 MHz frequency range operating bothin fundamental mode and in harmonic modes that extend to 15 MHz. However, testing ofharmonic modes above 15 MHz is not covered by this standard.
