What materials are used in the phantom fabrication?
The protocol uses polylactic acid for molds and polyvinyl alcohol (PVA) as the tissue-mimicking material.
How does the 3D printing process work?
3D printing involves creating molds from STL files and using a rigid material to print the anatomical structures.
What imaging techniques are utilized?
CT and MRI data are used to create patient-specific models for the phantoms.
Why are patient-specific phantoms important?
They allow for better surgical planning, instrument testing, and clinical training by providing realistic anatomical representations.
What is the significance of the freeze-thaw cycle?
The freeze-thaw cycle helps in solidifying the PVA and ensuring the structural integrity of the phantom models.
Can the protocol be adapted for other anatomical structures?
Yes, the methods can be modified to create phantoms for various anatomical structures based on specific needs.
