MESH MIXER | 3D SLICER | 3D PRINTS

Working with a physician to pre-contour a plate for a patient. 3D Slicer was used to segment the mandible and MeshMixer was used to smoothen the model as well as mirror the jaw for pre-contouring of the plate.

Patient education for prostate cancer is vital if a procedure is to be done. MeshMixer, the tumor was hollowed and filled with red resin to highlight the tumor to show a patient for consultation.

Jaw case, the mirrored mandible was used for contouring the plate, used to test fit a surgical guide to help improve surgical outcomes.

The mandible guide would be used to align the saw on the mandible to make the cuts at a specific angle. The fibula guide would then aid in providing the bone segments needed to fill the gap in the mandible seamlessly as the cut angles were pre-planned. The guides improve surgical times and patient outcomes by reducing time under and improving facial features.

Employing 3D Slicer, MeshMixer, and PreForm to expertly tailor a patient-specific guide for a mandible reconstruction with fibula-free flap for an edentulous patient. Guides printed using FormLabs 3B+ printer and sterilized using steam sterilization.

Before beginning the segmentation process, a CT scan with good spatial resolution and sub-millimeter slice thickness aid in differentiating the anatomy of the heart. Due to the collaboration with SickKids Hospital, I learned CT anatomy of the heart one on one with a cardiologist, which significantly improved the outcome of the segmented model. Once the anatomy was understood, a threshold was used as a mask to outline the heart’s essential structures, including the ventricle blood pools, pulmonary artery, atrium’s, and other vital features. A range of tools was used, including; grow from seeds, fill between, and smoothening to create the 3D model from the CT scan. MeshMixer was used to inspect and correct any issues within the STL mesh, while Fusion 360 was used for rendering and adding joints.

While 3D printing the heart, the pulmonary veins, including the left and right inferior and superior veins, were clipped, and supports were added under the veins during printing.
