1. A method of irradiating a target in a subject, comprising the steps of:
- positioning a subject on a supporting device;
positioning a delivery device adapted to deliver charged particles; and
delivering charged particles to a target in the subject, wherein the delivery device is in motion and rotates around the target while at least some of the charged particles are delivered, and one or more parameters of the charged particles are modulated when the delivery device is in motion, said parameters including the energy, the intensity, and the beam direction of the charged particles.
