Automatic image registration of magnetic resonance imaging scans for localization, 3-dimensional treatment planning, and radiation treatment of abnormal lesions

This invention is a method of using the Magnet Center of a magnetic resonance imaging scanner, commonly referred to as MRI, as the common reference point to accurately film image an area of concern for parallel axial, sagittal and coronal parallel slices. The perpendicular axis of each of the parallel slices of film images from all three of the mutually perpendicular slices passes through Magnet Center of the MRI. Upon determination of the number of film image slices in each stack, the position of the first slice with respect to Magnet Center, and the thickness of each slice has been determined, this data is entered into a computer capable of producing three-dimensional images. Using the entered data and positioning lasers, the original position during scanning can be accurately reproduced in the simulator suite or room as well as in the Treatment room.
