Abstract

The invention provides a method for controlling ultrasonic three-dimensional imaging, comprising: setting and adjusting the scanning parameter P by the ultrasonic host computer; wherein, the frame frequency f value of the three-dimensional image imaging and the scanning parameter P are functional relationships; controlling the scanning parameter P according to the Scanning with a three-dimensional ultrasonic probe transducer; the ultrasonic probe transducer collects original echo data of a two-dimensional grayscale image; processes the original echo data of the two-dimensional grayscale image to construct a three-dimensional image and / or at least one section image . The method provided by the invention designs the three-dimensional image imaging frame frequency f value and the scanning parameter P as a function relationship, which can realize three-dimensional images with low frame frequency and high image resolution, and is especially suitable for static tissues, such as breast, thyroid, and pelvis. Fundus, uterus, and accessories do not require high real-time 3D images and focus on image resolution imaging of tissue parts, reducing the probability of misdiagnosis and missed diagnosis by clinicians due to low image resolution affecting diagnostic results.

Description

technical field [0001] The invention relates to the field of ultrasonic imaging, in particular to an ultrasonic three-dimensional imaging control method, imaging method and system. Background technique [0002] The three-dimensional imaging technology of the ultrasound imaging system has always been a research and development hotspot in this field because it can present the scanned object three-dimensionally and facilitate doctors to diagnose and treat the scanned object. Ultrasound three-dimensional imaging is a three-dimensional data structure transformed by computer processing on the basis of a series of continuous two-dimensional plane data collected. Due to the limited amount of original 2D echo data collection and transmission speed, in order to ensure the real-time performance of 3D image acquisition, the number of lines of each frame of raw data and the number of frames of scanned volume data are usually reduced. When the amount of original volume data is insufficie...
