This Java applet allows you to select and view high-resolution images of 2-dimensional slices of a human body, using image data taken from the National Library of Medicine's Visible Human Project.

This applet has won some awards and been featured in some magazines, books and TV shows.

Some mirror sites are now available. Choose the one that is closest to you in order to speed up downloading of the images.

Main Panel : There are three types of image slices -- Axial, Sagittal, and Coronal. Small (preview) images for each of these viewpoints are displayed in the main panel of the viewer. Moving one of the cutting lines will create a new slice through the Visible Human. Image Controls : Select the type of slice you want by clicking on the image or the viewpoint name. This will highlight the name in blue, and the cutting line which produced that image will change from red to cyan. To chose a new slice, click on the cutting line and drag it to a new position. A new preview image will appear after you release the mouse button. Resolution Controls : Choose the image resolution appropriate for your network connection by clicking one of these buttons: Low resolution images are around 10 - 50 KBytes. Medium resolution images are around 25 - 150 KBytes. High resolution images are around 50 - 350 Kbytes. Access Controls : The adjust buttons (the triangle buttons) let you fine tune the exact slice number (shown in blue). If you want to see the full size image of the slice you have just chosen, press the Load button to pop up an image slice window.
