Abstract
Official abstract text for this publication.
Disclosed is an X-ray imaging device, which is capable of providing a tomographic image of an image layer disposed between an axis of rotation and an X-ray source. The imaging device according to the present invention includes a radiography unit having an X-ray source and an X-ray sensor disposed to face each other with a rotating axis therebetween, wherein the X-ray sensor configured to obtain X-ray transmission images, a driver configured to rotate the X-ray source and the X-ray sensor about the rotating axis, and an image processor configured to provide a two-dimensional tomographic image of an image layer disposed between the rotating axis and the X-ray source, by shifting and overlapping the X-ray transmission images after reversing left and right at least some of the X-ray transmission images.
First claim
Opening claim text (preview).
The invention claimed is: 1. An X-ray imaging device comprising: a radiography unit having an X-ray source and an X-ray sensor, wherein the X-ray source and the X-ray sensor are disposed to face each other with a rotating axis therebetween and rotate about the rotating axis in a first direction, the X-ray sensor is configured to obtain a plurality of X-ray transmission images; and an image processor configured to generate a two-dimensional tomographic image of a target object in a region of interest in a patient's predetermined region, another object in a different image layer of the same region partially blocking said target object from being directly detected by the X-ray sensor, said image processor further configured to: flip the image orientation, in a left to right direction, of at least some of said plurality of X-ray transmission images of the target realign all of the flipped X-ray transmission images with each other in the first direction, such that the image of the target object in the flipped X-ray transmission images appears at a same position within each flipped transmission image, and overlaying the realigned, flipped X-ray transmission images on each other, such that the images of the target object overlap within each of the flipped, aligned, and overlaid transmission images to create said two-dimensional tomographic image.
