SIST EN 61157:2008/A1:2014

Standard means for the reporting of the acoustic output of medical diagnostic ultrasonic equipment

This International Standard is applicable to medical diagnostic ultrasonic equipment.
– It provides a set of traceable acoustic parameters describing the acoustic fields.
– It defines a standard means and format for the reporting of the acoustic output information.
– It also describes a reduced dataset recommended for equipment generating low acoustic output levels.
NOTE The information tabulated in this standard format can be used for
a) exposure planning for biological effects studies;
b) exposure data for prospective epidemiological studies conducted using exposure conditions similar to those reported in this standard. In the absence of actual exposure data for retrospective epidemiological studies, the information tabulated in this standard format might also be used with
cautionary comment.

number, n, of consecutive half-cycles (irrespective of polarity) divided by twice the time
between the commencement of the first half-cycle and the end of the n-th half-cycle
NOTE 1 None of the n consecutive half-cycles should show evidence of phase change.
NOTE 2 The measurement should be performed at terminals in the receiver, that are as close as possible to the
receiving transducer (hydrophone) and, in all cases, before rectification.
NOTE 3 This frequency is determined according to the procedure specified in IEC/TR 60854.
NOTE 4 This frequency is intended for continuous-wave systems only.
