Research on the Calibration of Speed of Sound of Phantoms Used in Ultrasound Bone Sonometers
As a clinical instrument for measuring human bone mineral density,the calibration of ultrasonic bone mineral density meter has been widely concerned.At present,the calibration of this kind of instrument mainly a-dopts the measurement mode,and the mode on the market has limitations on the setting range of the key measure-ment index"sound speed".Therefore,based on the principle analysis and test,this paper studies the sound veloci-ty calibration method of this kind of module,so as to provide reference for the development of new module and solve the calibration and traceability problems.
