TomoTherapy® Hi-Art System®
ROS is the first facility in the Northeastern U.S. to offer TomoTherapy, which delivers the most effective
treatment with the fewest side effects of any radiation therapy
technique available in the world.
It integrates CT imaging and Intensity Modulated Radiation Therapy
into the same treatment machine. Unlike conventional linear accelerators
that only deliver treatment from a few fixed locations, the system
can treat cancer from all 360 degrees as it rotates around the patient.
It also enables radiation oncologists to compare planned radiation
doses with actual doses so that adjustments can be made at the time of treatment.
Tomotherapy’s extreme precision enables us to deliver high levels of radiation only to the areas that need it. For more information about TomoTherapy, click here.
Varian Clinac 2100C Linear Accelerator
This machine accurately and quickly delivers high-energy
photons and electrons, providing an excellent method for treating
deep-seated tumors (using photons), as well as superficial tumors
p-Reference Frameless Stereotactic Radiosurgery System
This system is superior to others in that it offers
immobilization and precise treatment of brain cancers without the
use of an uncomfortable head frame bolted to the patient’s
skull. The system’s specialized treatment planning software
calculates the precise location of the target based on the location
of three permanent gold bb’s used as reference points. Using
these coordinates, the patient is aligned for each treatment with
millimeter accuracy and thus treated effectively with minimal discomfort.
GE Highlight Advantage CT Scanner
CT simulation replaces conventional two-dimensional
x-ray simulation and provides us with cross-sectional images of
a patient’s anatomy that are used to determine the exact location,
shape and size of tumors as well as surrounding normal tissues and
organs. This improved accuracy has a positive impact on treatment
ADAC 3-D Treatment Planning
System with Smart Sim
Corvus IMRT Treatment Planning System
3D treatment planning enables a higher accuracy and
less likelihood of damage to normal tissue than conventional planning.
Information from a CT scan of the patient in actual treatment position
is transferred to the computer’s planning system. The physician
defines both tumor and normal tissues on each CT slice (every 3
to 5 mm), and then the computer reconstructs the site in three dimensions.
The Advanced ROS physics staff and physicians use this information
to determine the size, shape, number, and characteristics of the
radiation beams most appropriate for treatment. The final result
is a unique treatment plan designed to deliver a lethal amount of
radiation to the cancer while minimizing the amount of radiation
to normal tissue.
NOMOS B-Mode Acquisition and Targeting (BAT)
This is an image-guided system that when integrated
with our ADAC Treatment Planning System and a linear accelerator
permits the radiation therapist to make daily adjustments in patient
position to account for internal movement of organs. Radiation can
then be directed at the smallest possible area with improved accuracy,
minimizing side effects and radiation to normal tissue. Advanced
ROS was the first facility in Rockland County and only the second
in New York State to offer this type of equipment.
Varian VariSource High Dose Rate (HDR) Remote Afterloader
The Afterloader machine enables delivery of
High Dose Rate brachytherapy in the shortest possible time, usually
minutes, by using a small, high-activity, computer-controlled radioactive
seed that is passed through a catheter and directed at tumors in
the lung, esophagus, prostate and others. This technology offers
the convenience of outpatient treatment for some patients, in contrast
to Low Dose Rate (LDR) brachytherapy which often requires a 2-3
day hospitalization due to the extended treatment times required.
