Touch of Life Technologies (ToLTech) sells a full line of health education software under the name VH Dissector. The software is used in professional, graduate, and undergraduate anatomy programs. The software is installed in more than 140 institutions. The first major upgrade to the software has been shipping since August 2005. In the first quarter of 2006 ToLTech added two new products: 1. The Virtual Edge (Lessons that run on the VH Dissector) a pro-section guide for undergraduate anatomy, and 2. The Surface Palpation Guide (Lessons that run on the VH Dissector) that covers the techniques used to locate and palpate over 200 structures near the surface of the human body. ToLTech has developed a knee arthroscopy simulator in partnership with the American Academy of Orthopaedic Surgeons. This simulator will go into validation testing in 2006. The firm are currently developing other procedural simulators in the areas of orthopaedics, gastroenterology, rheumatology, radiology, ophthalmology, and general surgical procedures.
