Ultrasonic probe adaptive imaging system

Abstract

The invention discloses an ultrasonic probe adaptive imaging system. The imaging system is adaptively imaged according to a geometric parameter and an acoustic parameter of each element in a probe; specifically, in a transmitted beam synthesis module or a received beam synthesis module, a transmission delay value or a receiving delay value and an apodization coefficient of each element are calculated according to the geometric parameter and the acoustic parameter of each element, so focusing points of the transmitted beam synthesis or the received beam synthesis are more centralized through control over transmission delay or receiving delay of each element, signals at the focusing points are stronger, and image quality is improved; a side lobe of a transmitted beam or a received beam is suppressed and image effect is optimized through control over the apodization coefficient of each element; demodulation central frequency and demodulation bandwidth of a demodulation and filter module are matched with central frequency and bandwidth which are stored in the probe to further improve the image quality; therefore, the ultrasonic image quality is improved by better matching the transmitted beam synthesis module, the received beam synthesis module, the demodulation and filter module with the probe in the imaging system; and by using the ultrasonic probe adaptive imaging system, the control cost and the defective rate of the probe are also reduced.

Description

technical field [0001] The invention relates to an adaptive imaging system of an ultrasonic probe. Background technique [0002] Medical ultrasound imaging integrates multidisciplinary principles and technical means such as ultrasound physics, modern electronics, informatics, and biomedicine. It is one of the fastest-growing and most widely used technologies in medicine after X-ray imaging technology. There are many factors that affect the quality of ultrasound images, including transducers, host systems, and monitors. Among them, the transducer (or probe) is one of the key factors of ultrasonic imaging and the source of ultrasonic images. No matter how good the host is, if the performance of the transducer is not good, good ultrasound images will not be obtained. Probe manufacturers control the design parameters of the probe within a certain error range to be qualified. The better the probe manufacturer, the better the error range can be controlled. If the performance o...

[0006] At present, some probe manufacturers store some information of some probes, such as the propagation time TOF of the primitive, and the sensitivity of the primitive, into the probe, and the system makes some design compensation according to the probe to improve the imaging quality, but these are far from enough of
