Abstract
A radiography machine provides information about the absolute dimension of imaged objects with as few as two images taken along a common axis at different separations. The information gathered in this way may also be used to deduce absolute or relative separation of the objects along the common axis.
Claims19
A radiographic machine comprising:
- a radiographic radiation source;
- an imaging radiation detector;
- a support structure adapted to hold the radiographic radiation source in opposition to the imaging radiation detector about an imaged object along an image axis positioned with respect to the imaged object;
- and
- an electronic computer communicating with the imaging radiation detector and executing a stored program to:
- (a) receive a first image of the imaged object from radiation passing through the imaged object from the radiographic radiation source to the imaging radiation detector at a first separation between the radiographic radiation source and the imaged object along the image axis;
- (b) receive a second image of the imaged object from radiation passing through the imaged object from the radiographic radiation source to the imaging radiation detector at a second separation between the radiographic radiation source and the imaged object along the image axis;
- and
- (c) output an absolute size of the imaged object in a dimension perpendicular to the image axis from a comparison of the first image and second image.
