Abstract

An embodiment of the invention provides an ultrasonic three-dimensional reconstruction method and device. The method comprises: determining dimensions of reconstruction volume data, wherein the dimensions include a coordinate origin of the volume data, dimensional size of the volume data and inter-voxel physical spacing; traversing each pixel in a two-dimensional ultrasonic plane corresponding to a two-dimensional ultrasonic image sequence, mapping each pixel of the two-dimensional ultrasonic plane into three-dimensional volume data through Bessel interpolation algorithm, and carrying out interpolation; performing hole completion on the three-dimensional volume data through a kernel regression algorithm. The ultrasonic three-dimensional reconstruction method and device provided by the embodiment of the invention enable reconstruction quality of three-dimensional reconstruction to be improved effectively by the combination of the Bessel interpolation algorithm and kernel regression algorithm.

Description

technical field [0001] The present invention relates to the technical field of surgical navigation based on ultrasound guidance, and more specifically, to a method and device for ultrasound three-dimensional reconstruction. Background technique [0002] With the rapid development of minimally invasive surgery and precision medicine, image-based surgical navigation systems have gradually become the mainstream of surgical operations. The specific position of the organ tissue during the operation is connected with the computer and combined with the relevant surgical instruments, which can accurately display the three-dimensional spatial position of the organ tissue and the spatial position relationship with the adjacent important tissues. It can still be positioned accurately, guides the operation to be carried out safely, saves time, and improves the operator's self-confidence to a large extent, avoids the occurrence of serious complications such as damage to important structu...
