Abstract

The invention relates to a position calibration method applied in three-dimensional ultrasonic imaging data acquisition. By means of the acceleration value and the angular velocity value of an ultrasonic probe acquired by a positioning device mounted on the ultrasonic probe, the displacement of the ultrasonic probe generated in two scanning intervals is calculated, so that coordinate values of pixel points formed by the target space scanning in a world coordinate system are calculated in sequence, to achieve the goal of accurately spatially positioning each pixel point acquired in the three-dimensional imaging data, and the basic guarantee is provided for subsequent three-dimensional image reconstruction.

Description

technical field [0001] The invention relates to the technical field of medical ultrasonic imaging data processing, in particular to a position calibration method applied in three-dimensional ultrasonic imaging data acquisition. Background technique [0002] Ultrasonic imaging diagnostic technology plays an important role in modern medical diagnostic technology because of its real-time, non-invasive, portable and low-cost advantages. Among them, 3D ultrasound imaging is one of the important development directions of medical ultrasound imaging technology. 3D ultrasound imaging generally includes 3D image data collection, image data post-processing, 3D image reconstruction, 3D image display, and quantitative measurement. Data acquisition is the most basic step in 3D ultrasound imaging and the basis for ensuring the accuracy of imaging. [0003] The acquisition of 3D imaging data refers to all echo information within the entire volume range of the structure of interest, that is...
