Laminography apparatus
First Claim
1. An X-ray laminography apparatus for imaging an object utilizing at least a first and a second X-ray detector spaced from a source of X-rays and a computer, Comprising:
- a. an X-ray tube window, the X-ray from the source of X-rays passing through said window b. means for obtaining a first image from the first X-ray detector of X-rays passing through said window;
c. means for obtaining a second image from the second X-ray detector of X-rays passing through said window; and
d. means for removing an optical gradient from said first and second images.

Abstract
A laminography apparatus utilizing at least a pair of detectors spaced from a source of X-rays. The X-rays emanate from a tube window and create images in the detectors. Optical gradients are removed from the images obtained by the detectors through a first computer program. The position of each of the detectors relative to the source of X-rays is also determined by a mask which permits a second computer program to process position information. In addition, the brightness of the images obtained by the detectors is adjusted using a third computer program based on any one of a number of detectors providing a brightness standard.
