A handheld ultrasound device and imaging method

Abstract

The invention relates to a handheld ultrasonic device and an imaging method. The device comprises a probe part, a transmitting module, a receiving module, an echo data processing module, a controllerand a communication module; the controller controls the transmitting module to generate transmission pulses so that the probe part can be stimulated to transmit ultrasonic wave signals; the controllercontrols the receiving module to collect ultrasonic echo signals received by the probe part; the echo data processing module processes the ultrasonic echo signals collected by the receiving module and then sends the data to the communication module; the communication module communicates with external image receiving equipment in a wireless or wired mode; the controller conducts low-power-consumption scanning control on the transmitting module and the receiving module, wherein low-power-consumption scanning control comprises the steps that the transmitting module is controlled to conduct widening transmission, the receiving module is controlled to conduct widening receiving, it is controlled that low-power-consumption empty scanning is generated, the transmitting module is controlled to work during ultrasonic transmission, and the receiving module is controlled to work when receiving effective data. According to the device and the method, on the basis that the system performance is notdegraded, power consumption is reduced, probe overheating is prevented, and endurance time is prolonged.

Description

technical field [0001] The invention relates to a handheld ultrasonic device and an imaging method. Background technique [0002] In traditional ultrasonic equipment, the main body of the probe part is the ultrasonic transducer, which mainly realizes the conversion of electrical signals and ultrasonic signals, including converting high-voltage emission pulses into ultrasonic waves and converting ultrasonic echoes into echo electrical signals; The signal is then transmitted to the ultrasonic host through the cable for processing. Traditional ultrasound trolley equipment is powerful, but bulky; with the expansion of ultrasound application fields, more and more low-performance portable ultrasound equipment has appeared on the market. These equipment can be hand-held or hand-held, but the system structure , which is basically the same as the traditional trolley equipment, and the ultrasonic probe is connected to the host computer through a cable. [0003] In recent years, a mo...

Problems solved by technology

If the power consumption of a handheld ultrasound device is too high, it will cause the device to overheat or have a short battery life; therefore, how to control power consumption is the primary problem faced by this type of handheld ultrasound device

Products currently on the market mainly limit power consumption in two ways: one is to reduce performance, including function limitations, image quality, and channels; the other is to limit continuous working time to prevent the probe from overheating

[0005] These two methods have their obvious shortcomings: the first one controls power consumption by reducing performance, which limits the application range of such products; the second one controls power consumption by limiting continuous working time, which causes additional problems for operators the inconvenience
