Abstract


Purpose: In 3-dimentional conformal radiotherapy for lung cancer, the tumour position will change with the breath motion and the heart beating. This change is one important gist for confirming the scope of the internal target volume. How to confirm and control the scope of the affection moving with the breath motion, and nicely sketch the treatment target volume, not leave out the affection section when reducing the radiation to well organic around, have become to an important problem in current research. Recently, the several different methods that the scholar have bring forward which resolve the problem for confirming the ITV because of the breath motion are not very well. This task, depending on the correlated research experience, we design and make the active breath control system, complete the monitoring and controlling to the patient breath motion state, and carry clinic employing validate for the whole system, complete the individualized ITV.Materials and Methods: 1 Design and make the active breath control system: the principle of the system is following, writing the program and empoldering graphics interface, and collecting the state information of the breath motion for the
