The Novalis Tx® treats patients with a procedure called stereotactic radiosurgery, a nonsurgical method of treating tumors with high-dose radiation precisely aimed from different angles.

¤ SBRT is a specialized form of radiation therapy
administered in no more than five treatments by an
advanced radiosurgery system. During treatment, high
doses of radiation are delivered to tumors with pinpoint
precision. A typical treatment session takes about 15
minutes and does not require surgery or sedation. Due to
the extreme accuracy of radiation delivery, side effects,
if any, are usually minor and temporary.

4. Proton Therapy
¤ Proton therapy is a type of particle therapy in which high-
energy proton beams are delivered to tumors by a
cyclotron. With proton therapy, doctors determine the
precise point in a patient’s body where the proton
releases the majority of its energy, maximizing exposure
to cancer cells while minimizing exposure to normal
tissue. Proton therapy is usually delivered in 20-35
treatments with typical outpatient sessions lasting less
than five minutes. Side effects, such as fatigue, are
usually minor and temporary.

6. Our Center
¤ Opened in 2008 through a partnership with Palomar
Health, San Diego Radiosurgery specializes in
stereotactic radiosurgery using Novalis Tx®
technology. Our center was one of the first in the
country to treat a patient using the Novalis Tx
radiosurgery platform with ExacTrac® adaptive
gating. This technology enables doctors to adjust the
size and shape of radiation beams, compensating for
patient movement and minimizing radiation exposure
to healthy tissue. San Diego Radiosurgery has
extensive experience treating lung cancer patients,
which represent the majority of our cases.
