X-ray target centering apparatus for radiographic imaging system
First Claim
1. A radiographic imaging system comprising:
- a. a pair of stops, at least one stop being horizontally repositionable with respect to the other stop, wherein the stops have a space defined therebetween, whereby an X-ray target may be situated between the stops;
b. a sensor providing a sensor signal dependent on the distance between the stops;
c. an X-ray source providing X-rays across a target field having a field size dependent on the sensor signal.

Abstract
An apparatus for properly centering and/or collimating an X-ray beam with respect to a target to be radiographically imaged. A field definer is situated between an X-ray source and an X-ray detector at the location where the target is to be situated. The field definer includes a pair of stops between which the target may be located, and the stops may be horizontally relocated relative to each other to be placed in abutment with the target. A sensor in communication with the stops produces a signal dependent on the distance between the stops, and a controller utilizes this signal to adjust the X-ray source to emit radiation in a desired area with respect to the field between the stops. As an example, a target may be situated between the stops, the stops may be adjusted in abutment with the target, and the X-ray source will then be collimated to emit a radiation beam which is incident only on the target between the stops.
