A Quantitative Ultrasonic Detection Probe with Embedded Normalized Acoustic Mode

Abstract

The invention relates to a quantitative ultrasonic inspection probe with an embedded normalized sound die and belongs to the technical field of biomedicine detection. The quantitative ultrasonic inspection probe with the embedded normalized sound die comprises a probe casing (1) having a supporting and protecting effect, a front end acoustic transmission detection face (4), a standard sound die (5) covered with a rear end embedded acoustic transmission calibration surface (6), a transducer detection cavity (2), a calibration cavity (9), a rotating shaft (7), an ultrasonic transducer (3) and an ultrasound transmitting and receiving signal cable (8), wherein the transducer detection cavity (2) and the calibration cavity (9) are positioned between the front end acoustic transmission detection face (4) and the rear end embedded acoustic transmission calibration surface (6); the rotating shaft (7) is placed between the transducer detection cavity (2) and the calibration cavity (9), the ultrasonic transducer (3) can be overturned through 180 degrees upwards around the rotating shaft (7), and the ultrasound transmitting and receiving signal cable (8) is led out of the side bottom of the probe casing (1). The transducer detection cavity (2), the calibration cavity (9) and the ultrasonic transducer (3) are consistent in geometric dimension. The quantitative ultrasonic inspection probe has the advantages of being simple and convenient in operation process, uniform in standard and high in accuracy.

Description

technical field [0001] The invention relates to a quantitative ultrasonic detection probe embedded with a normalized acoustic mode, which belongs to the technical field of biomedical detection. Background technique [0002] Ultrasonic detection has the advantages of non-invasive, real-time, intuitive and cheap. It can obtain the tissue structure, shape and echo information of blood flow in the internal organs of the human body and image them. It has important value in diagnosis and has become one of the main means of clinical examination and diagnosis. [0003] However, traditional ultrasound imaging is affected by many factors, including the instrument's own working parameter settings such as transducer parameters, ultrasound transmission frequency, power, echo gain, filter characteristics, etc., and related processing in the imaging process such as beam forming, focusing, etc. and degeneration etc. The influence of these factors makes it difficult to quantitatively analy...
