Abstract
Systems/techniques that facilitate correction of intra-scan focal-spot displacement are provided. In various embodiments, a system can access a first gantry angle of a medical scanner. In various aspects, the system can determine a first displacement of a focal-spot of the medical scanner based on the first gantry angle, by referencing a mapping that correlates gantry angles to focal-spot displacements. In various instances, the system can compensate, via one or more focal-spot position adjusters of the medical scanner, for the first displacement.
