This instructable will show you how to create an edible chocolate brain from sliced data sourced from an MRI scan.
Our colleague at Inition, Andy Millns had his brain MRI scanned as part of a research project (he didn't say what into!) and we managed to sneak a copy (get your copy below!).
The main steps involved are:
- Converting sliced DICOM data into the STL file format (a 3D geometry format widely used for 3D printing)
- Editing that model to clean up
- 3D printing a solid model
- Producing a latex mould
- Finally casting the chocolate and eating (image of Andy eating his own brain above).
We've made the original DICOM files and the STL file available for download below under the Creative Commons Attribution License. If you like the project - we would be very happy if you voted for it in the Instructables 'Make it Real' challenge - the voting button is top right of this page.
Step 1: DICOM Data Import
We did this using InVesalius 3, an open source medical application (available for Windows and GNU Linux).
First, import your sliced DICOM image files into InVesalius. For highly detailed data you may need to limit the number of images that are used to generate the 3D model.
