Abstract

The invention discloses a three-dimensional ultrasonic real-time imaging method and system based on area-array probes. The method comprises the following steps of data collecting, delay overlapping, baseline calibrating, envelope detecting, logarithm compressing, downsampling, grey mapping and three-dimensional displaying. The system comprises an external circuit used for generating trigger signals, a lower computer used for collecting data in real time according to the trigger signals to complete the data collecting step and transmitting modulated data to an upper computer and the upper computer used for receiving the data transmitted by the lower computer and displaying a three-dimensional image in real time. According to the three-dimensional ultrasonic real-time imaging method and system based on the area-array probes, real-time imaging of the three-dimensional ultrasonic image is achieved.

Description

technical field [0001] The invention belongs to the field of ultrasonic imaging, and more particularly relates to a method and system for real-time three-dimensional ultrasonic imaging based on an area array probe. Background technique [0002] Ultrasound imaging is the use of ultrasonic beams to scan the human body, and obtain images of organs or tissues in the body by receiving and processing information that carries characteristics of human tissue or structural properties. Due to the advantages of no ionizing radiation, low price, and convenient use, ultrasound has become an important diagnostic imaging method in clinical medicine today. [0003] Three-dimensional ultrasound can provide rich three-dimensional space information, make up for the deficiency of two-dimensional ultrasound imaging, and provide assistance for the diagnosis and treatment of diseases. Real-time three-dimensional ultrasound can provide navigation for clinical operations, further expanding the appl...
