X-ray image-based three-dimensional object imaging method

Abstract

The invention discloses an X-ray image-based three-dimensional object imaging method, which comprises the following steps of: 1, acquiring X-ray data, namely shooting an X-ray planar two-dimensional image of an object to be reconstructed every certain fixed angle by using X-ray image acquisition equipment to form a two-dimensional image sequence {Pt}, wherein t=1,2,3,...,n, and each X-ray planar two-dimensional image comprises an pixel subscript (i,j) in a detector of the X-ray image acquisition equipment, namely a column position and a row position corresponding to the pixel; 2, reconstructing a three-dimensional object, namely reconstructing the acquired X-ray planer two-dimensional image to obtain the three-dimensional texture representation of the object to be reconstructed; and 3, displaying the three-dimensional object, namely rendering the three-dimensional texture representation of the object to obtain the three-dimensional image of the object to be reconstructed. By utilizing the technology of reconstructing the three-dimensional representation of a corresponding object by a plurality of X-ray images, a more comprehensive, vivid and three-dimensional method for observing an internal structure of an object is provided.

Description

technical field [0001] The invention belongs to the technical field of computer applications, in particular to a method for three-dimensional imaging of objects based on X-ray images. Background technique [0002] Since 3D models can provide more spatial information and observation dimensions than 2D images, 3D models have been increasingly used in industries, medical care, education and other fields in recent years. X-ray images are an important means of obtaining information about the internal structure of objects, but the result presented by the images is a two-dimensional projection of the object. In the formed image, the projections of the interior of the object in the direction of the ray are superimposed, and it is impossible to intuitively understand the situation inside the object. CT is another widely used medical diagnostic equipment. It can be used to understand the internal situation of objects, but it has the disadvantages of large radiation dose and inability...

Problems solved by technology

X-ray images are an important means of obtaining information about the internal structure of objects, but the result presented by the images is a two-dimensional projection of the object. In the formed image, the projections of the interior of the object in the ray direction are overlapped, and it is impossible to intuitively understand the situation inside the object

CT is another widely used medical diagnostic equipment. It can be used to understand the internal situation of objects, but it has the disadvantages of large radiation dose and inability to apply diagnosis during surgery.

[0003] Existing X-ray image acquisition equipment includes emission sources and detectors, such as figure 1 As shown, only a single plane of X-ray image acquisition can be completed. How to use the existing acquisition equipment to achieve 3D imaging with the lowest cost and minimal changes to the existing equipment is a major difficulty in the field of current research.
