Phys Imaging Radiat Oncol
. 2024 Aug;
31:100609.
PMID: 39132555
Background And Purpose: The impact of intrafractional motion and deformations on clinical radiotherapy delivery has so far only been investigated by simulations as well as point and planar dose measurements....

. 2024 Aug;
121(1):218-229.
PMID: 39122095
Purpose: STereotactic Arrhythmia Radioablation (STAR) showed promising results in patients with refractory ventricular tachycardia. However, clinical data are scarce and heterogeneous. The STOPSTORM.eu consortium was established to investigate and harmonize...

Radiat Oncol
. 2023 Nov;
18(1):185.
PMID: 37941012
Background: Stereotactic arrhythmia radioablation (STAR) is delivered with a planning target volume (PTV) prescription dose of 25 Gy, mostly to the surrounding 75-85% isodose line. This means that the average...

. 2023 Mar;
34(4):555-564.
PMID: 37001999
Purpose: Volumetric modulated arc therapy (VMAT) is a widespread technique for the delivery of normo-fractionated radiation therapy (NFRT) and stereotactic body radiation therapy (SBRT). It is associated with a significant...

Int J Radiat Oncol Biol Phys
. 2022 Jun;
114(2):360-372.
PMID: 35716847
Purpose: Cardiac radioablation is a novel treatment option for patients with refractory ventricular tachycardia unsuitable for catheter ablation. The quality of treatment planning depends on dose specifications, platform capabilities, and...

Radiother Oncol
. 2022 Mar;
170:205-212.
PMID: 35351536
Background And Purpose: MR-guided radiotherapy (MRgRT) allows real-time beam-gating to compensate for intra-fractional target position variations. This study investigates the dosimetric impact of beam-gating and the impact of PTV margin...
