Standardized visualization of electro- or mechano-anatomical data allows easy inter- and intra-patient comparison. For this purpose, we developed the open-source and freely available UNISYS (Universal Ventricular Bullseye Visualization) software. A patient-specific mesh of the ventricular anatomy typically consists of a certain number of vertices and their associated values. Based on a limited amount of user inputs, the algorithm transforms these 3D single-layer coordinates to a circular 2D disk ('bullseye') through a number of translations and rotations, and interpolates them to achieve a continuous standardized visualization. The algorithm shows a high degree of bidirectionality and a robust spatial preservation of points of interest.
