For Stereotactic Radiosurgery of lung tumor, 4 dimensional CT was done during for free breathing of the patient. The movement of the treated target was measured in the CT images, and appropriate breathing cycle was selected for treatment. For patient A, the movement of the treatment target was 10.1 mm during full breathing cycle, and 5.4 mm for treated breathing cycle, 30∼70%.
