Abstract

Automatic implant design in the browser.

We introduce a fully automatic system for cranial implant design, a common task in cranioplasty operations. The system is integrated in Studierfenster, an online, cloud-based medical image processing platform. Enhanced by deep learning algorithms, the system restores the missing part of a skull and generates the desired implant by subtracting the defective skull from the completed skull. The generated implant can be downloaded in STereoLithography (.stl) format directly via the browser and used for further post-processing or 3D printing workflows.

Fully automatic

Deep learning restores missing skull anatomy without manual implant modeling.

Cloud-based

The workflow runs through an online medical image processing platform.

3D printable

The resulting implant is downloadable in standard STL format.
