Methods Based on the techniques of conformal radiotherapy, a new split method for fabricating the three-dimensional physical compensator was developed to achieve IMRT.

This paper analysis the characteristic and reason in view of the powdered coal pipeline arranges on three dimensional ripple compensator’s, and put forward several proposals, to compensator’s shaping, the arrangement,the application and the hanging bracket design have certain reference value.

The research on 3D cutter radius compensation for computer numerical control system;
