Varian Medical Systems

St. Luke's Cancer Center is a Varian Medical Systems Show Site

The St. Luke’s Cancer Center has the most-advanced cancer-fighting technology available anywhere

Varian Medical Systems has selected St. Luke’s Cancer Center as a show site for the latest cancer-fighting technology. As a Varian show site, health care professionals from cancer centers around the world can see the most sophisticated Varian equipment in a clinical setting at St. Luke’s Cancer Center.

Patients benefit from the following Varian technology available through the St. Luke’s Cancer Center...


Trilogy® linear accelerator

Trilogy is the most advanced radiosurgery system in the world. It delivers all forms of external beam radiation therapy to treat tumors throughout the body, including those in the brain, head and neck, lungs, liver and prostate. Trilogy’s superior image-guidance technology and unmatched beam-shaping capabilities, doctors can target tumors that are close to important structures.

Trilogy treats brain tumors without surgery. The system keeps the patients head stable in a special frame attached to the skull. Doctors then direct radiation beams at the tumor. Since the beam is so precise, the normal healthy tissue around the tumor and delicate structures such as the optic nerve, brain stem and spinal cord are not harmed.

The Trilogy system offsets any movements a patient might make. And since they can continue breathing normally, they are more comfortable during treatment.

Overall, patients benefit from faster treatments, far less radiation exposure to normal tissue, greater comfort and fewer side effects.


Clinac iX® linear accelerator

The Clinac iX® combines the latest radiotherapy treatment technology with produced that show changes in a tumor’s shape, size or position over time. Tumor motion also is tracked. This gives a clear indication of how a tumor will move during treatment due to breathing, for instance.

RPMTM, the Clinac iX’s® respiratory pacing system, makes it possible to deliver bursts of radiation that match a patient’s natural breathing cycle. Doing so cuts down on the amount of radiation to which healthy surrounding tissue is exposed. Because the beam is so precise, patients don’t have to hold their breath during treatment. This is especially beneficial for patients with lung cancer whose breathing is affected by the disease.


VariSourceTM 200 HDR Afterloader

This advanced brachytherapy system offers precise irradiation treatments for breast, prostate, cervical and endometrial cancers, as well for tumors in the bronchial passageways.

With HDR brachytherapy, doctors place the radioactive source into the tumor for irradiation from the inside out. It is regarded as the best technology for delivering high-dose rate brachytherapy. It allows doctors to deliver radiation directly into tumors through tiny needles controlled by a computer. The computer moves the radiation source on a wire within the needle, in keeping with the treatment plan.

This particular system has the thinnest source wire available for high-dose rate procedures. This allows treatment options that are not possible with other systems, and provides the highest success ratio possible.


On-Board Imager®

The On-Board Imager featured on the Clinac® and Trilogy™ medical linear accelerators is a system for image-guided radiation therapy (IGRT). It is useful for treatment of thousands of cancer patients. The system allows clinicians to see high-resolution X-ray images to locate tumor sites and, when needed, change the patient’s position. The system improves the effectiveness of cancer treatments by giving doctors the ability to target and track tumors more accurately, while reducing the amount of healthy tissue exposed to radiation during treatment.


SmartBeam IMRT®

Featured on the Clinac and Trilogy linear accelerators, SmartBeam IMRT® uses computer-generated images to plan and deliver more focused radiation beams to tumors than is possible with conventional radiation therapy. A special device called a multileaf collimator shapes the radiation beam to conform to the shape of the tumor. The linear accelerator can be rotated around the patient to send radiation beams from the best angles to reach the tumor while sparing healthy tissue.

IMRT can increase tumor control while sparing surrounding healthy tissues and reducing side effects. It treats tumors that in years past had been considered untreatable because they are near important organs and structures. In the case of head and neck tumors, IMRT allows doctors to deliver radiation in a way that reduces exposure of the spinal cord, optic nerve, salivary glands and other important structures. In the case of prostate cancer, exposure of the nearby bladder or rectum can be minimized. Doctors use IMRT to treat tumors in the brain, breast, head and neck, liver, lung, nasopharynx, pancreas, prostate and uterus.


SonArrayTM system

The SonArray patient positioning system enables doctors to better target tumors. The system uses 3-D images and optical guidance to adjust a patient's position while in the treatment position. Doctors cam make position adjustments to patients to make sure radiation beams are aimed precisely at the tumor, reducing the amount of healthy tissue exposed to radiation during treatment.
