STEREOTACTIC SURGERY

The use of highly advanced computers to
locate and create a three-dimensional image of
a tumor is called stereotaxy. When used during
surgery, this technique is called stereotactic
surgery. Conventional x-rays can only measure
two dimensions: height and width.
Stereotaxyadds the third dimension of depth, which
enhances the neurosurgeon’s ability to precisely
map the location of the tumor and find the best
and safest pathway for removing it.
Stereotactic techniques may be used to prepare
for a surgery, during biopsy or tumor removal,
while implanting radiation pellets, or to provide
a navigation system during surgery. These
techniques are especially useful in locating and
removing tumors deep within the brain, such as
brain stem and thalamic tumors. Stereotactic
systems are used in operating rooms, enabling
surgeons to view images of the brain as surgery
is being performed.
