Our Process
Data Acquisition
CT with contrast is the gold standard for getting highly detailed 3D images of vasculature. The contrast is important here because it raises the attenuation of the vasculature and allows for a better image. Luckily, this type of data is usually already available for patients with AAAs. A CT with contrast has likely been used in the diagnosis of the aneurysm or is done in preparation for FEVAR.
Segmentation
This is the process of Digitally separating out the organs of interest from the rest of the anatomy. It is done directly with DICOM data and relies on differences in attenuation aided by proper imaging, the anatomical knowledge of a trained Biomedical engineer, and some pretty clever software.
Digital Model Prep
After the aorta is digitally separated from the surrounding anatomy it still has some parts which aren’t needed. Most of the smaller and branching vasculature, as well as some length of the aorta, are not useful. They aren’t involved in the surgery being planned. The model also has to be prepared for 3D printing, having the appropriate file type, solid volumes, building supports, and calculating ideal orientation.
3D Printing
We use state-of-the-art SLA printers with 4K resolution mono LCDs and a 50-micron printing resolution. these machines print using resin, which is cured with the precise application of UV light into a hard solid.
Post Processing
This is where the magic happens, all of the work that takes place after printing. The models come out of the resin basin with external supports, and with a cloudy haze. It’s through our specialized finishing process that the resin becomes crystal clear.
