Dosimetric, mechanical, and geometric verification of conformal dynamic arc treatment [PDF]

Journal of Applied Clinical Medical Physics, 2003
A conformal dynamic arc (CD‐arc) technique has been implemented at the S. Giovanni Calibita‐Fatebenefratelli Hospital Radiotherapy Center. This technique is performed by rotational beams and a dynamic multileaf collimator (DMLC): during the treatment delivery the gantry rotates and the field shape, formed by the DMLC changes continuously.
