Three-dimensional reconstruction of the superior mediastinum from Chinese Visible Human Female

This research aimed to construct three-dimensional (3D) visible models of the superior mediastinum for anatomic study and surgical approaches to the superior mediastinum. Sectional images of the superior mediastinum were acquired through the Chinese Visible Human Female (VCHF) database. One hundred eighty images of the superior mediastinum were imported into Photoshop CS and the images were converted into a JPEG format. Surface and volume reconstruction were performed by 3D Doctor 3.5 and Amira 4.0 software programs on an ordinary personal computer, respectively. The surface and volume reconstruction of the superior mediastinum were successful. The surface reconstruction model allowed rotation and magnification of the superior mediastinum structures as well as displayed the contours of reconstructed structures individually or as a composite with any other selected structure. Volume reconstruction displayed abundant internal detail of reconstructed images in transverse, coronal, sagittal, and random oblique sections. Three-dimensional, visible models of the superior mediastinum based on the sectional images of VCHF can provide unique insight into the anatomy of superior mediastinum. These models provide an excellent adjunct to the anatomy curriculum in medical schools and an invaluable tool for the practicing surgeon planning an operation in this complex anatomic region.
