radiosurgery uses computer technology that allows doctors to deliver radiation
with unprecedented precision, and without the uncomfortable screws or frames
that were previously used to immobilize patients during treatment.
A new upgrade in November 2004 included Skeletal Structure Tracking (SST) for
spinal radiosurgery. The use of SST eliminates the use of
fiducials for treating patients with spinal lesions.
An upgrade in May 2004 included
Synchrony Motion Tracking for extracranial treatments such as lung, pancreas
and liver cases. With Synchrony,
patients do not have to hold their breath during treatment. Treatment time is
much shorter now. Upgrade also includes the AXUM autocouch, which also reduces a
patient's treatment time.
