What is sub-surface laser engraving?
Sub-surface laser engraving (SSLE) is a technique used to create three-dimensional representations within glass by engraving anatomical data.
How are the anatomical labels attached?
Labels are suspended within the glass medium, ensuring they do not obstruct the view of the anatomical structures.
What types of imaging data can be used?
The method can utilize clinical or preclinical x-ray CT datasets for model creation.
What software is used for model preparation?
3D Slicer and Netfabb Studio Basic are commonly used for generating and preparing models.
Can the models be modified in size?
Yes, the dimensions of the models can be adjusted to fit specific sizes before engraving.
What is the advantage of using this method for education?
The method provides clear, labeled models that enhance understanding of anatomical structures without visual obstruction.
