Transmit Energy Verification of Linear Amplifiers for Medical Doppler Ultrasound Scanners

This article explores the transmit energy of a linear amplifier used in medical Doppler driver systems. In order to verify the mechanical pulse strength of the ultrasonic wave generated by the ultrasonic probe excited by the linear amplifier, the actual weight of the transmitted wave has been measured using an electronic balance, and the relationship between the weight and the amplitude of the transmitted signal. In addition, the acoustic pressure fields was measured using a calibrated hydrophone. The intensities of energy density were calculated and the quality of underwater signals has been verified.
