Method for extracting and fusing two-dimensional image from three-dimensional tomography

Abstract

The invention discloses a method for extracting and fusing a two-dimensional image from three-dimensional tomography. The method comprises steps that an X-ray tomography apparatus is utilized to emitX-ray signals to the target three-dimensional space, the computer tomography is utilized to reconstruct a target three-dimensional space image; an ultrasonic sensor is utilized to detect the target three-dimensional space, and signal acquisition and reconstruction of images in the present detection plane are carried out; a displacement sensor and an angle sensor are utilized to detect the positionand angle information of the ultrasonic sensor in the three-dimensional space; in combination with the position and angle information of the ultrasonic sensor, a two-dimensional image of the presentdetection plane is extracted from the three-dimensional X-ray tomography image and is fused with an ultrasonic image, through integrating the X-ray and ultrasonic detection means, the detection imagewith higher precision is acquired.

Description

technical field [0001] The invention belongs to the field of ultrasonic imaging and X-ray imaging processing, in particular to a method for extracting and fusing two-dimensional images from three-dimensional tomographic imaging. Background technique [0002] After decades of research and application, the application of X-ray tomography imaging in various fields is also deepening. Tomographic imaging can be applied to many occasions that require high-precision detection due to its high resolution of reconstructed images. However, X-ray tomographic imaging also has its disadvantages. When there are multiple targets in the detection area and there are mutual occlusions between the targets , X-ray tomographic imaging cannot image the target area well. Ultrasonic imaging has been widely used due to its advantages of convenient operation, good real-time performance, and no radiation. However, the resolution of ultrasonic imaging is not as high as that of X-ray tomographic imaging....

Tomographic imaging can be applied to many occasions that require high-precision detection due to its high resolution of reconstructed images. However, X-ray tomographic imaging also has its disadvantages. When there are multiple targets in the detection area and there are mutual occlusions between the targets , X-ray tomographic imaging cannot image the target area well. Ultrasonic imaging has been widely used due to its advantages of convenient operation, good real-time performance, and no radiation. However, the resolution of ultrasonic imaging is not as high as that of X-ray tomographic imaging. Therefore, a new method is needed to combine the respective advantages of the two imaging methods to achieve more accurate image reconstruction
