From: Single isocenter stereotactic radiosurgery for patients with multiple brain metastases: dosimetric comparison of VMAT and a dedicated DCAT planning tool

Fig. 3

The relative difference in V10Gy and V12Gy between DCAT and VMAT scattered against the sphericity of the corresponding PTV. The reported volumes are normalized to the value obtained with the MBSRS tool. A sphericity value of 1 corresponds to a perfect sphere, values < 1 to shapes deviating from a sphere. Markers above the red dotted line correspond to lesions where DCAT was superior, markers below to lesions where VMAT was superior
