| Abstract Scope |
Intracorporeal bioprinting, meaning printing inside the body, is an emerging technology at the intersection of Additive Manufacturing, Surgical Robotics, and Tissue Engineering. Intracorporeal Bioprinting may improve outcomes over conventional bioprinting by manufacturing tissue engineering constructs directly in the body, reducing morbidities and decreasing recovery times. In this application, it is difficult to acquire data about a surface because surfaces in the body are deformable. Several methods have been presented previously, but many incorporate scanning methods which may be ineffective inside the body. We propose a method for using data from a CT scan as an initial estimator of the surface, followed by Trilinear Coordinates Measuring to adapt the model to changes in the surface. The method will be evaluated by using a benchtop bioprinter to extrude biomaterial mimics onto predesigned surfaces that exhibit a range of curvatures where the CT scan does not accurately represent the surface. |
