The absolute difference of the measurements among 2D-TEE images, 3D-TEE images and 3D printed models of ASD
The absolute differences of maximum diameter and the minimum diameter between 3D printed models and the 2D-TEE images were 0.51±0.39mm, 0.54±0.35mm, respectively. The absolute differences of the maximum diameter, minimum diameter and circumference measured from 3D printed models and 3D-TEE images were 0.43±0.33 mm, 0.52±0.38 mm, 1.21±0.66 mm, respectively. Indicating that the 3D printed ASD models can retain and copy the original information of the source images, and no intolerable errors have been introduced during the complicated printing process.
