Problems solved by technology

In addition, limited by the speed of traditional scan reconstruction calculations, the image and position information obtained by scanning are usually saved locally and then reconstructed, but this method loses the great advantage of real-time ultrasound imaging
Especially when the traditional three-dimensional ultrasound imaging technology is applied to the imaging of the skeletal system, it will face many problems such as large and uneven scanning area, changing scanning range due to patients, different scanning methods and postures due to different practical applications, and uneven scanning speed. The unconstrained free scanning method can obtain high-quality data to the greatest extent to obtain high-quality images

Abstract

The invention provides an unconstrained scanning and voxel-based three-dimensional real-time bone imaging method. According to the method, a voxel-based reconstruction algorithm in a traditional three-dimensional reconstruction technology is applied to skeletal system imaging, a traditional projection method used in the algorithm is optimized and accelerated, and an FDP method is proposed to achieve a real-time reconstruction effect. Because the method provided by the invention is a voxel-based reconstruction algorithm, large-area and large-range imaging (covering the whole back area of a general adult) can be carried out. The method is different from a traditional stacked scanning reconstruction method for three-dimensional bone imaging to the greatest extent. Finally, the technology provided by the invention is also suitable for general non-real-time reconstruction, and is used for accelerating the whole reconstruction process.

Description

technical field [0001] The invention relates to a three-dimensional real-time bone imaging method, which belongs to the technical fields of medical imaging and ultrasonic bone imaging. Background technique [0002] Traditional two-dimensional ultrasound imaging is an indispensable technology in modern medical imaging due to its flexibility, non-invasiveness, no radiation and low cost. However, due to the lack of 2D image information and the difficulty of identification, 3D ultrasound imaging is developing into a new imaging technology. [0003] Three-dimensional ultrasound imaging technology is to embed a sensor in the traditional ultrasound probe to track the position of the probe when it is moved, and then combine the two-dimensional image of the probe to reconstruct a three-dimensional image of the scanned area. At present, in the process of large-scale three-dimensional ultrasound imaging, researchers often use a hand-held probe to scan the region of interest. In the t...
