This
is a low resoluion demonstration of the type of surgical simulation being
developed. Using a force reflecting device, known as the PHANToM haptic
interface from SensAble Devices, Inc.,students will be able to simulate
surgery using the Visible Human data set.
As the scapel moves
along the knee, the computer model displays the correct incision. The
scalpel cuts through the skin and underlying tissue, allowing the fat,
muscles, and blood vessels to be revealed.
This same demonstration
can be downloaded in a lower
resolution MPEG file format. Some resolution was sacrificed to keep
the file size down to approx. 1.5 MB. The original full
resolution MPEG is also available, but be warned, this file could
take quite awhile to download, as the file size is approx. 6.0 MB.
Practical applications
for the Visible Human database are being discovered almost daily. At the present
time, surgical simulators are showing the greatest promise. Just as simulators
have become a standard in the fields of aviation and aerospace, surgical simulators
will be a standard in the field of medicine. They will teach correct procedures
to physicians in training, before they ever have to cut on a live patient. And
practicing surgeons will also find these tools useful for honing skills they
already possess and for developing new techniques. At the Center for Human Simulation,
we have the tools to build these simulators, but require time and funding to
develop these projects to their fullest potential.
Additional applications
for the anatomical database include simulating pathological conditions, such
as tumors and degenerative diseases, to provide researchers with a greater insight
into the diseases they are investigating. Physicians might also be able to use
this tool to explain a patient's condition and possible treatment options in
greater detail, hopefully, giving patients a better understanding of their problem.
Other possible ideas for the database involve simulators for trauma management,
biomechanic motion, disease models, localized stereotactic treatment, and radiological
imaging.
The Visible
Human Dataset provides a complete submillimeter anatomical visual description.
The Center for Human Simulation has demonstrated the ability to simulate surgically
cutting into the database in real time on existing graphics hardware. The algorithms
being developed here are the underlying foundation for flexible, highly realistic
surgical simulators based on real anatomy and physiology.
