Conditions
- Ultrasonic Power for the transducer assembly = 16.7 mW
- Ultrasonic element diameter = 1.1 cm ( 9 ultrasonic elements are used in the
transducer assembly. )
- Duty Factor(DF) =Pulse Duration x Pulse Repetition Frequency = 128 x 10
3,472 = 0.444416
- Area corresponding to entrance beam dimensions = 9(the number of ultrasonic
element in the transducer assembly) x 3.14 x 0.55
- I @ Transducer Face = Ultrasonic Power / Area Corresponding to entrance
SATA
beam dimensions = 16.7 / 8.54865 = 1.95352482555725 ≒ 1.95 mW/cm
- I @ Transducer Face = I
