Basic of array pulse echo ultrasonic transducer
Electroacoustic characteristics and measurement methods
1 Scope
This standard specifies the characterization parameters, measurement conditions, measurement methods and steps of the basic electroacoustic characteristics of the array pulse echo ultrasonic transducer.
This standard is applicable to the use of piezoelectric transducers, operating frequency is 1.5MHz ~ 15MHz, coupled with ultrasound pulse echo diagnostic system
Integrated array of ultrasonic transducers.
This standard applies to the electroacoustic characteristics and measurement methods of the transducer part of the ultrasonic probe.
Note. The definition and measurement methods of the electroacoustic characteristic parameters of the array pulse echo ultrasonic transducer are described in references [1] and [2].
