Abstract
A medical imaging system includes an x-ray source () having a focal spot that emits radiation that traverses an examination region (). The position of the focal spot along a longitudinal direction is a function of a temperature of one or more x-ray source components. The system further includes a detector () that detects the radiation and a collimator (), disposed between the x-ray source () and the examination region (), that collimates that radiation along the longitudinal direction. A focal spot position estimator () dynamically computes an estimated position of the focal spot along the longitudinal direction based on the temperature of one or more x-ray source components. A collimator positioner () positions the collimator () along the longitudinal direction based on the estimated focal spot position prior to performing a scan.
