Our Process

Over the last decade, SickKids has developed and refined a complete workflow for creating accurate 3D heart models from CT and MRI scans, thanks largely to Dr. Shi-Joon Yoo and a dedicated team of surgeons, physicians, and engineers. This process allows you to understand complex anatomy in three dimensions, rehearse surgical approaches, and support clearer communication with your team, patients, and families.

Isolating the anatomy you need to plan complex cases

Your CT or MRI scans are segmented to highlight the specific cardiac structures, defects, and surrounding vessels that matter for your decision-making. The resulting 3D files can be hollowed, trimmed, or layered with features such as valves and arteries so you can focus on the details that are hardest to appreciate on standard imaging.

Turning imaging into a model you can hold

Your segmented heart file is converted into a physical model using 3D printing materials chosen for your purpose; rigid plastics for precise anatomical demonstration, or softer materials when you need to simulate surgical handling. A full-size pediatric heart typically prints within several hours, giving you a tangible model to review with colleagues, trainees, or families ahead of intervention.

Process to Practice

This workflow is used both to create custom patient‑specific models and to develop the standardized training and education models available through our store. These models can support your treatment planning, surgical rehearsal, teaching, and patient communication. Explore how the 3DHeartLab can apply this workflow to your cases and training programs.
