Problems solved by technology

In such a structure, if the voltage applied from the transmitter power supply to the ultrasonic sensor is low, the voltage difference between the bias power supply and the transmitter power supply becomes large, resulting in large power consumption
[0009] This power consumption results in short operating times and high heat generation in portable ultrasound diagnostic devices powered by battery-operated ultrasonic transducers.

Abstract

For the purpose of reducing the size and power consumption of a power source in an ultrasonic diagnostic apparatus, charge pump circuits (50 and 60) are connected to a transmitter power source (14). A regulator in the transmitter power source (14) drives the charge pump circuit (50) to generate a positive bias voltage +HV2 higher than a positive voltage +HV1 generated by the transmitter power source (14). The regulator in the transmitter power source (14) also drives the charge pump circuit (60) to generate a negative bias voltage -HV2 lower than a negative voltage -HV1 generated by the transmitter power source (14).

Description

technical field [0001] The invention relates to an ultrasonic diagnostic device, which is used for transmitting ultrasonic signals from an ultrasonic sensor to an object to be detected, and receiving the reflected waves of the ultrasonic signals for display, in particular to a small and low energy consumption ultrasonic diagnostic device. Background technique [0002] A commonly used conventional ultrasonic diagnosis is to image the inside of an object by applying ultrasonic waves to a region to be inspected inside the object with an adjacent ultrasonic probe, and to generate images of echo signals of reflected waves of the applied ultrasonic waves. Since ultrasonic waves are harmless to living bodies, ultrasonic diagnostic devices are particularly suitable for medical applications, and are used to detect foreign bodies in living bodies, determine the degree of damage, observe tumors or fetuses, and the like. [0003] In recent years, there has been a desire to reduce the si...
