METHODS AND SYSTEMS FOR COLLIMATING

摘要

A collimating system for collimating radiation received under different angles for performing tomography includes a static collimator having a plurality of collimating apertures, and shutters for separately and temporarily shutting at least two of the collimating apertures. The shutters have a shutting element for blocking the at least two collimating apertures, and at least one collimating element distinct from the shutting element for collimating radiation passing through non-shutted collimating apertures in a direction so as to control overlap between radiation stemming from different non-shutted collimating apertures. An imaging system includes a collimating system, and a method for collimating and a corresponding controller and software related products.
