Following informed consent to treatment by cRA, the patient underwent 4D computed tomography for treatment planning performed with a SOMATOM Sensation Open CT scanner (Siemens) as well as a contrast-enhanced electrocardiogram (ECG)-triggered cardiac CT (SOMATOM Definition Flash, Siemens) for co-registration in the treatment planning system (Varian Eclipse version 15.5; Varian Medical Systems Inc. Paolo Alto CA, USA). A pre-specified internal target volume (ITV) for respiratory motion management was enlarged by 4 mm to result in the planning target volume (PTV), which consisted of 104 cm3. The treatment planning procedure and consideration of organs at risk followed the protocol of the RAVENTA study.9 (link) Target volume transfer from the electroanatomic mapping (see Supplementary material online , Figure S2 ) to the treatment planning system was accomplished using the CARDIO-RT software.10 (link) Dose distribution was calculated using the AAA/Acuros AXB algorithm and cRA was performed on a Varian TrueBeam STX in four non-coplanar volumetric modulated arcs using a 6 mV flattening filter-free photon beams.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
