Figures
- Fig 1.
Sample simulation result from the SurgicalPreview computational modeling software showing a 3D model of the FD inside a pretreatment vessel (A), a frame from a deployment video (B), and a cross-section of the FD (red) and vessel (blue) at a position along the vessel centerline (C).
- Fig 2.
Examples of posttreatment clinical reconstructions (red/left) and pretreatment simulation results (black/right) for the same FD sizes. The deployment pairs are sorted in ascending order according to the difference between actual and simulated device lengths, which ranged from 1.58 to 4.06 mm.
- Fig 3.
Bland-Altman plots showing dots that represent differences between the actual clinical and simulated deployments in FD length (A) and FD diameter (B). The plots show the means for the deployment pairs on the x-axis and the differences between pairs on the y-axis.
- Fig 4.
Average FD diameters for the actual clinical and simulated deployments. Error bars in the clinical FD diameter measurements were calculated by averaging 15 random measurements of FD thickness along the length of each reconstructed FD model.
