Global Maximum Derated I
SPTA
and MI Values
The following values represent worst-case values of the I
SPTA.3
and MI for each transducer and each
mode, over all operating conditions for that mode. These tables fulfill the requirements of Appendix
G, Section C2, of the September 30, 1997 issue of the FDA document, “Information for
Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers.”
