Abstract
The invention comprises a method and apparatus for scanning charged particles in a cancer therapy system, comprising the steps of: (1) providing a first and second dipole magnet system and a gap, the gap comprising a common gap length, along a path of the charged particles, within both the first and second dipole magnet systems, the gap comprising a progressively increasing x/y-plane cross-section area from an entrance area of the charged particles into the double dipole magnet system to an exit area of the double dipole magnet system, the x/y-plane perpendicular to a z-axis from a center of the entrance area to a center of the exit area; (2) scanning the positively charged particles along a first axis of the x/y-plane using the first dipole magnet system; and (3) scanning the positively charged particles along a second axis of the x/y-plane using the second dipole magnet system.
