Embodiment

[0022] An ultrasonic diagnosis and imaging method thereof, comprising the steps of:

[0023] (1) Image acquisition: using the magnetic field space positioning free arm scanning technology, the magnetic field space positioning free arm scanning technology uses a set of probe space positioning system, which consists of three parts: electromagnetic field generator, space position sensor and microprocessor , the electromagnetic field generator controlled by the microprocessor emits electromagnetic fields into the space, and the spatial position sensor is fixed on the probe. When the operator conducts random scanning with the probe with the spatial position sensor, just like a conventional ultrasonic inspection, The computer can perceive the movement trajectory of the probe in the three-dimensional space, so as to determine the spatial coordinates (x, y, z) and image orientation (α, β, γ) of each frame of two-dimensional images obtained, with spatial coordinate information and The ...

Abstract

The invention relates to the technical field of ultrasonic imaging, in particular to ultrasonic diagnosis and an imaging method thereof. The method comprises the following steps of 1 image collecting, 2 image postprocessing, 3 three-dimensional reconstructing, 4 three-dimensional image displaying and 5 three-dimensional quantitative measuring. The method has the advantages that the sampling time is short, sampling can be completed within one breath-holding period of a patient, and an error caused by viscera organ moving is avoided; the vascular structure can be displayed without needing an intravenous injection contrast agent, and ionizing radiation and wounds do not exist; the method is economical and convenient, the reliance on the technical level of an operator is reduced, and the repeatability is enhanced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging, in particular to an ultrasonic diagnosis and an imaging method thereof. Background technique [0002] Ultrasonic diagnostic instruments apply ultrasonic detection technology to the human body, and understand the data and shape of physiological tissue structures through measurements to achieve the purpose of discovering diseases. The basic principle of ultrasonic imaging is to use the specific acoustic impedance and attenuation characteristics of different pathological tissues of the human body, and then produce different reflections and attenuations. The strength of the echo signal is sequentially displayed on the screen with light points of different light and dark, and then the cross-sectional ultrasonic image of the human body can be displayed. [0003] However, in ultrasonic imaging, due to the influence of factors such as the roughness of the reflective surface of human tissue an...
