This section contains 3D modules that demonstrate thoracic anatomy. The modules are up to 60mb in size so it is recommended that you download the modules to run them. To do this, please right click on the image and choose "save link as". You will need QuickTime Player to run the modules if your computer does not automatically prompt you. Alternatively, you can run the modules directly from your browser, but you will have to wait for them to load completely, which can take several minutes.
