OsiriX® software allows the trained user to render a 3 dimensional virtual representation based on images captured during diagnostic CT and MRI scans. OsiriX® software can assign levels of transparency and color to select tonal values and stack each slice relative to its position during the initial scan to create “3D Reconstructions” that can be manipulated and exported as image files. These 3D Reconstructions improve the understanding of anatomic relationships as they exist in the living body. They may be used to supplement anatomy instruction, provide an adjunct to traditional dissection, and improve surgical planning. Traditional dissection often requires the removal, displacement or distortion of superficial anatomy in order to access deeper structures. The non‐destructive and reversible nature of virtual dissections allows a trained user to remove or isolate structures selectively, permitting the visualization of a particular region or tissue. Measurements of distance and volume are also possible. Diagnostic images of both living patients and cadavers destined for dissection can be reconstructed and used to correlate diagnostic images to the actual anatomy of a patient or cadaver. Cost and practical concerns of setting up a 3D workstation, usability of the OsiriX® software, as well as patient confidentiality issues will be discussed. Several case studies will be presented.
