IMRT for lung cancer

IMRT for lung cancer

Three-dimensional planning with IMRT allows your radiation oncologist to simultaneously treat multiple lung cancer tumors with different doses of radiation, while sparing healthy tissue in the lung and elsewhere.

RapidArc® shortens treatment times

RapidArc is an advanced technology we use to deliver IMRT with speed and precision.

RapidArc radiation therapy shortens treatment times to one-half up to one-eighth that of standard radiation therapy. In a single 360-degree rotation, a linear accelerator revolves around the patient, delivering a sculpted, tightly focused beam of radiation directly to a tumor in less than two minutes.

This results in better tumor targeting and less damage to surrounding healthy tissue. It also reduces the amount of time a patient spends in radiation treatment, which is usually administered five days a week for several weeks.

Respiratory gating may help reduce side effects

We also use respiratory gating to accurately target tumors by adjusting for tumor motion during IMRT.

Tumors, such as those near the lungs, often move as a result of breathing and other involuntary movement in the body. Respiratory gating enables us to “paint” concentrated doses of radiation onto tumors with greater accuracy. The system tracks tumor motion as a result of breathing, helping us to target the tumor and protect healthy tissue from receiving unnecessary radiation during intensity modulated radiation therapy.
