Abstract:
In an imaging system provided with an X-ray tube and a detector having a surface lying in a specified plane, wherein said tube is spaced apart from said detector surface by a source-to-image distance along a first axis, and wherein said tube is disposed to project an X-ray beam characterized by beam direction and beam width angles toward said detector, a method for selectively aligning said detector surface and the field of said beam which is projected into said specified plane, said method comprising the steps of:providing a value of said beam width angle; locating the geometric center of said beam field from said distance, said beam direction angle and said beam width angle value; and establishing a specified positional relationship between the center of said detector surface and said geometric center of said beam field along a second axis which is orthogonal to said first axis.
