Walters TE, Kistler PM, Morton JB, et al. Impact Of Collimation On Radiation Exposure During Interventional Electrophysiology. Europace. 2012 Nov;14(11): 1670-1673.

Fluoroscopy remains a cornerstone imaging technique in contemporary electrophysiology practice. We evaluated the impact of collimation to the ‘minimal required field size’ on clinically significant parameters of radiation exposure. Significant reductions in radiation exposure were seen with the practice of routine maximal collimation. The largest reductions were seen during ‘simple’ ablation procedures.
