Background
! Assessment of produced models for accuracy and reliability will include: ! QualitaFve and quanFtaFve comparison of models. ! CompleFon challenges and Fme commitment evaluaFon. ! Survey subjects overall saFsfacFon with the process.
! Understanding cross-‐secFonal anatomy is important in interpreFng medical images such as magneFc resonance imaging (MRI).1 Unfortunately interpreFng three-‐dimensional (3D) relaFons from two-‐dimensional (2D) images is one of the most difficult skills to learn and teach.2
Purpose
! To enhance physical therapy students’ educaFon of anatomy and pathology by creaFng a learning process, using easily accessible computer-‐aided design (CAD) soOware and low cost 3D prinFng technology to independently create a virtual 3D model of structures from a series of MRI slices.

Outcomes
Figure 1: Steps for Development of Learning Process to Date
! SoOware accessible to students has been idenFfied and an instrucFonal process created. ! IdenFfied Adobe Illustrator as the most accessible soOware that is compaFble with imporFng images, rendering, and prinFng. ! IdenFfied AutoDesk AutoCAD soOware over AutoDesk Inventor due to availability and Mac compaFbility, and SketchUp due to lack of efficient curve tool. ! Developed and documented step by step instrucFons for students to outline areas of interest in series of MRI images with Adobe Illustrator (Figure 2). ! Developed and documented step by step instrucFons for students to import their outlines into AutoCAD, extract the images and create virtual 3D solid body models for viewing and 3D prinFng (Figures 3 and 4).
