1. A modular X-ray source assembly apparatus for a motion compensated multiple pulsed X-ray source tomosynthesis imaging system, comprising:
a plurality of multi-pin connectors on respective enclosures to drive a high voltage circuit, to control a filament, to get high voltage feedback and to measure temperature;
a plurality of connector engagement alignment guides; and
a plurality of modular and user replaceable modules each coupled to the respective multi-pin connector and including:
a plurality of high-voltage generating circuit boards inside the respective enclosure; and
a connector adapted to be coupled to the respective multi-pin connector,
wherein the user replaceable modules comprise X-ray sources adapted to be mounted on a primary motor stage moving on an arc rail with a motor that engages and controls a speed of the primary motor stage, and when an individual X-ray source has a speed equal to a group source speed, but with an opposite moving direction, the individual X-ray source and an X-ray detector are activated with an exposure control unit.
