ABSTRACT:
A method for manufacturing single focus and cone beam collimators with precisely focused focal line or focal point. The method includes the steps of: forming a collimator body by using a metal casting process; measuring a displacement of a focal position of the collimator body with respect to an intended focal position; determining an adjustment size to minimize the measured displacement; adjusting the focal position of the collimator body by changing a physical size of peripheral regions of the collimator body according to the determined adjustment size. In this method, the physical size of peripheral regions of the collimator body can be changed either by cutting or attaching peripheral adjustment portions. Also, the physical size of peripheral regions of the collimator body can be changed to tilt an optical axis of the collimator body. The method should preferably be applied to segments of the collimator body separately.
