IMRT

Intensity Modulated Radiation Therapy (IMRT) will offer many patients new promise in fighting cancer.  IMRT (Intensity Modulated Radiation Therapy) conforms the treatment beam (radiation) to the exact size and shape of the cancerous tumor and modifies the intensity (strength) of the radiation beam to deliver the greatest dose directly to the tumor while sparing surrounding healthy tissue.

With IMRT, the radiation beam can be shaped and varied in intensity so it is precisely tailored to the patient’s tumor.  The shape changes as radiation is delivered from different angles, so that the tumor is always targeted and healthy tissues are protected.  Because the IMRT technology is so precise, doctors can spare the healthy tissue around the tumor, while giving higher doses to the cancer itself.  As the radiation dose to the tumor is increased, the cure rate is also increased and the risk of side effects is decreased.

St. Mary is committed to providing the most advanced technology and treatment protocols for patients with cancer.  IMRT technology is a very exciting and significant advance in radiation therapy.
