Noninvasive cardiac radioablation beam arrangement and isodose distributions. Patient 7 underwent noninvasive cardiac radioablation via 6 MV flattening filter-free photon beam and stereotactic volumetric modulated arc radiotherapy technique. A total of 25 Gy was prescribed to internal target volume (ITV) and 20 Gy to planning target volume (PTV) in a single fraction by simultaneous integrated boost strategy. Shown are (a) beam arrangement in noninvasive cardiac radioablation plan, and (b) dose distributions on the axial view. The colorwashed areas indicate the following: red, the ITV; and blue, the PTV. The orange, red, light green, blue, yellow, pink, indigo, and dark green lines represent isodose curves of 2875, 2500, 2375, 2000, 1750, 1500, 1250, and 1000 Gy, respectively. The radioablation dose distribution figure was created by using treatment planning system (version 15.6, Eclipse, Varian Medical Systems, Palo Alto, URL: http://www.MyVarian.com).
