Novel ultrasound medical imaging method

Abstract

The invention discloses an ultrasonic medical imaging method by utilizing a transmission method. As a novel ultrasonic medical imaging method, the invention is a fully digitalized ultrasonic medical imaging device realized by being based on a PC platform. The device particularly comprises a synchronizer, an emission control component, an ultrasonic emission transducer, an ultrasonic receiving transducer, a gating high pressure control component of an array element, a receiving control amplifying well-founded component, an A / D drive and transformation component, a digital beam forming component, a DSC data processing component, a display unit, the PC platform, a power supply unit, etc. The fully digitalized ultrasonic medical imaging device uses the parameters of sonic velocity and acoustic attenuation, and the like, and adopts medical imaging technology similar to a CT measuring method and the imaging algorithm. The measuring method is implemented by an ultrasonic emitter probe and an ultrasonic receiver probe which are coaxial and are arranged on both sides of a tested object. The imaging calculation method adopts algebraic reconstruction technique or back projection technique to reconstruct images. The ultrasonic medical imaging method has the advantages of good definition of the images reconstructed by digitization, no radiation to the human body and low cost, etc.

Description

technical field [0001] The invention belongs to the application field of ultrasonic medicine, adopts a method similar to a CT ultrasonic transmission method and an imaging algorithm to obtain ultrasonic medical imaging, in particular a new ultrasonic medical imaging method. Background technique [0002] Ultrasound medical imaging is one of the four major clinical imaging technologies and an important means of clinical diagnosis in medical units. The traditional ultrasonic medical imaging uses the reflection method, that is, an ultrasonic probe is used to transmit and then receive under the external excitation signal for scanning tomography. At the end of the 20th century, it was used for X-ray scanning tomography of the head and the whole body. The advent of imaging (X-CT) has created a new chapter of epoch-making significance for medical diagnosis, but X-rays are harmful to the human body and require ultra-high voltage power supply. Thus, a new ultrasonic medical imaging m...
