Design of high-intensity ultrasonic sound intensity measurement based on narrow pulse method
The research on high-intensity ultrasonic has taken the delectable achievement in the treatment of cancer and the detection of internal structure for the dam. The rapid and accurate sound intensity measurement of high-intensity ultrasonic transducer is necessary for its application and generalization. The paper introduces the principle of sound intensity measurement, proposes measurement scheme on the basis of the narrow pulse method and also discusses the design of hardware circuit and software.
Characterization of the Sound Field of High Intensity Focused Ultrasound
The methods of detection of high intensity focused ultrasound (HIFU) field are described in this paper, such as radiation forcer balance,hydrophone,optical fiber and optics from the difficulties and characteristics of high intensity focused ultrasound field, and also made the comparison in these methods.
A strategy for the development and standardisation of measurement methods for high power/cavitating ultrasonic fields: review of high power field measurement techniques.
This review was compiled as part of a project to formulate a UK strategy for the development and standardisation of measurement methods for high power/cavitating ultrasonic fields. It reviews the scientific literature relating to various methods of measuring high power fields which have been developed for application in health care, sonochemistry and industrial ultrasonics, and compares these methods in terms of attributes such as spatial resolution, bandwidth and sensitivity.
