ABSTRACT:
In an imaging system including a gantry having a patient bore, and a patient table having a cradle, a method of aligning the cradle with a scan plane in the patient bore is disclosed. The method comprises positioning a laser device at least partially within the patient bore, the laser device producing an alignment laser beam projecting along a center axis of the patient bore normal to the scan plane. The method further comprises aligning the cradle of the patient table such that when the cradle is translated into the scan plane in the patient bore, the alignment laser beam intersects a positioning target on the cradle.
