Method and apparatus for enhancing the contrast of a medical diagnostic image acquired using collimation |
摘要 |
An x-ray system that uses an x-ray source to irradiate a subject with x-rays is provided. A collimator is located proximate to the x-ray source and blocks a portion of the x-rays. A detector receives the x-rays and creates subject data indicative of a subject and collimator data indicative of a collimator. A position detector identifies a position of the collimator with respect to a field of view of the x-ray source. A gating module receives the subject and collimator data and passes at least a portion of the subject data. The gating module blocks at least a portion of the collimator data based on the position of the collimator. A display displays an x-ray image based on the portion of the subject data passed by the gating module.
