Abstract
We conducted a prospective clinical study (n = 14; 29% female) to assess the accuracy of a three-dimensional (3D) photography-based method of torso geometry reconstruction and body surface electrodes localization. The position of 74 body surface electrocardiographic (ECG) electrodes (diameter 5 mm) was defined by two methods: 3D photography, and CT (marker diameter 2 mm) or MRI (marker size 10 × 20 mm) imaging. Bland-Altman analysis showed good agreement in X (bias − 2.5 [95% limits of agreement (LoA) − 19.5 to 14.3] mm), Y (bias -0.1 [95% LoA − 14.1 to 13.9] mm), and Z coordinates (bias − 0.8 [95% LoA − 15.6 to 14.2] mm), as defined by the CT/MRI imaging, and 3D photography. The average Hausdorff distance between the two torso geometry reconstructions was 11.17 ± 3.05 mm. Thus, accurate torso geometry reconstruction using 3D photography is feasible. Body surface ECG electrodes coordinates as defined by the CT/MRI imaging, and 3D photography, are in good agreement.
