Basic of array pulse echo ultrasonic transducer Electroacoustic characteristics and measurement methods1 ScopeThis 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].2 Normative referencesThe following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 2900.86 Electrotechnical terms acoustic and electroacoustic GB/T 2900.88 Electrotechnical terminology GB/T 3102.7 Amount and unit of acoustics3 Terms and definitionsThe following terms and definitions as defined in GB/T 2900.86, GB/T 2900.88 and GB/T 3102.7 apply to this document. 3.1 Transducing element energy-transducingelement, activeelement A device that performs acoustic-electric and/or electrical-acoustic energy conversion in an ultrasonic transducer. Note. The transducer components used in medical ultrasonic transducers today include piezoelectric ceramics, piezoelectric single crystals, piezoelectric polymers, piezoelectric composite materials and micro silicon drums. 3.2 Ultrasonic transducer ultrasonictransducer In the ultrasonic frequency range, it is possible to convert electrical energy into mechanical energy (sound energy) and/or to convert mechanical energy (sound energy) into electrical energy. Device. Note. Medical ultrasound transducers typically consist of piezoelectric transducer elements, an acoustic impedance matching layer, a focusing acoustic lens, and a sound absorbing (damping) backing. Interacting with electroacoustics The physical properties of the device involved in the conversion are characteristic of the transducer. 3.3 Ultrasound probe ultrasonicprobe An overall generic term consisting of an ultrasonic transducer, an electrical shielding and mechanical protection housing, and an integrated cable. Note. When using mechanical sector scanning method, the motor is also equipped with motor and transmission mechanism, which is filled with sound-permeable liquid; high-frequency plane linear array transducer, and some are equipped with charging. Liquid coupling pad. 3.4 Array transducer arraytransducer An ultrasonic transducer arranged in an array by a plurality of transducer elements in a certain manner.
