Abstract
A system for cooling an X-ray tube in a CT machine comprising a heat sink for drawing heat away from the X-ray tube and a collimator connected to the heat sink and adapted to collimate the X-rays emitted by the X-ray tube and “focus” those X-rays on an X-ray detector, the heat sink body being formed out of the same material as the emitter of the X-ray tube, such that the emitter opening of the X-ray tube will remain aligned with both the heat sink window and the collimator opening even when the emitter of the X-ray tube undergoes thermal expansion.
