3DP
SLA
CT scan image data is used to create a 3DP computer model using medical imaging software. There are two options available for manufacturing the life-size model. the first option is stereolithography (SLA) and the second option is three-dimensional printing (3DP).
The CT data must be produced according to a specific scan
protocol so
the data is compatible with the imaging software and to ensure the
data will result in a highly accurate model. The imaging software translates
to CT data by delineating different densities. Hountsfield units are
used as a guide for determining hard tissue. After the CT data has
been segmented, the software interpolates the data on all three planes
to form a smooth three-dimensional model. A computer file of this model
is transferred to stereolithography equipment or three dimensional
printing equipment where a physical model of the patient's bone structure
is created.
