Multi-leaf collimator usually includes a plurality of leaves, a leaf guide configured to support the plurality of leaves, and a plurality of magnets. Each leaf includes a blocking portion that is radio opaque, a drive portion connected to the blocking portion, and a coil embedded in the drive portion. The coil is operatively connected to an electrical current source to generate a first magnetic field. The leaves have the capability of moving at speeds of 50 cm/s up to and higher than 1 m/s.

The present invention generally relates to radiation therapy. In various respects, the invention is directed to a highly responsive multi-leaf collimator, and method of use to provide radiation therapy utilizing beam shaping, intensity modulation and combinations thereof including simultaneous beam shaping and intensity modulation of therapeutic beams. Also the most important material for its radiation absorption is tungsten alloy material, which is a kind of high density, excellent machinability and good environmental-friendly. Tungsten alloy material plays a vital role for multi-leaf collimation radiation protection.
