A look into the process of producing biomodels (3D anatomical models) from medical imaging data. This presentation describes how we start with stacks of 2D medical images from CT and MRI scans and process the data to create accurate 3D models that replicate patient anatomy. These models can be produced in various virtual formats and can be physically fabricated using various 3D-printing technologies.

5. Data Acquisition
For patient-specific models
we start working from your
CT or MRI scans.
If a patient-specific model is not
required, we may have suitable
data on file in our anatomical
library.

6. Image
Segmentation
We segment the relevant anatomy from
stacks of scan images.
