Figure 3From: Optimal set of grid size and angular increment for practical dose calculation using the dynamic conformal arc technique: a systematic evaluation of the dosimetric effects in lung stereotactic body radiation therapyUndulated dose distributions in an axial plane for the case of S 3 . Doses were predicted for the spherical planning target volume with a diameter of 3 cm using a 2-mm grid size and angular increments of (a) 10° and (b) 2°.Back to article page
