A digital radiographic imaging system includes an offset table for determining mechanical and structural offsets which would, if not corrected, misalign the source and detector during use. The method can correct for inaccuracies in mechanical linkages, examination rooms and other mounting structures, and 'drift' induced during use of the system.

Method and apparatus for aligning an X-ray source and detector at various source to image distances

An x-ray imaging system ( ) for generating multiple energy x-ray images is provided. The system ( ) includes an exposure switch ( ) having an &ldquo;ON&rdquo;state. A console ( ) is electrically coupled to the exposure switch ( ) and contains two or more selected imaging program sets. An x-ray generator ( ) generates x-rays. An image detector ( ) detects the x-rays and generates two or more electronic signals. An image generation controller ( ) is electrically coupled to the image detector ( ) and controls the sequencing of the two or more electronic signals. An x-ray controller ( ) is electrically coupled to the console ( ) and the x-ray generator ( ). The x-ray controller signals the image generation controller ( ) to generate the two or more electronic signals sequentially when the exposure switch ( ) is in the ON state and in response to the two or more selected imaging program sets. A method for performing the same is also provided.

Multiple energy x-ray imaging techniques

A variable self-compensating detent control system for improved positioning accuracy and repeatability is provided. The detent control system provides a system for reducing positioning errors in the positioning of an X-Ray tube in an X-Ray imaging system, such as accurate and repeatable positioning of the X-Ray tube at detents. The control system preferably includes a sensor unit generating positional or velocity signals indicative of the position or velocity of the X-Ray tube and a microprocessor receiving the positional signals and determining an overshoot correction. The overshoot correction is used by the X-Ray system to control a locking system controlling the position of the X-Ray tube. The sensor unit may employ a potentiometer, a digital encoder, or preferably both in combination to determine the positional or velocity signals.
