Abstract
An x-ray machine, such as a mammography machine, comprises a source of a narrow beam of radiation which scans across an object, e.g., a breast, to be imaged. A sensor for the narrow beam moves in the same direction as the narrow beam. The sensor generates an output signal which indicates the position of the beam relative to a specific location on the sensor. A control circuit receives the signal from the sensor and outputs a control signal to regulate the position of the beam relative to the sensor.
