1. A method of radiating a moving target with a desired radiation dose, the target comprising a target tissue having blood flowing therethrough, the target tissue having a tissue surface including an inner surface bordering the blood and an outer surface, the method comprising: acquiring a series of computed tomography (CT) volumes encompassing the target tissue; identifying the target in three dimensions in the acquired CT volumes by visualizing a three dimensional surface rendering of the tissue surface of the target tissue and inputting the target with reference to the three dimensional surface rendering; computing a treatment plan according to the identified target; computing a dose distribution according to the computed treatment plan; visualizing a three dimensional display of the dose distribution superimposed with the three dimensional surface rendering of the tissue surface of the target tissue so as to verify the desired radiation dose at the target; and delivering the dose distribution to the target tissue to treat the target.
