Trilogy IGRT System

Dr. Bailey

Director of St. Anthony's Neuro-Oncology Program

The Trilogy is an excellent investment for the hospital. St. Anthony’s is a forward-looking institution. It is big enough to have a large selection of modalities we can use to treat our patients, yet it is small enough that they are not lost in the infrastructure. Patients enjoy the convenience.

Full Profile

St. Anthony's uses the Trilogy™ Stereotactic Image-Guided Radiotherapy (IGRT) System, which is the most advanced, sophisticated machine of its type in the world.

The Trilogy system combines imaging and treatment technologies, and can be used to deliver the widest range of external beam radiotherapies for cancer and neurosurgical treatments:

  • 3-D conformal radiotherapy
  • Intensity modulated radiation therapy (IMRT)
  • Stereotactic radiosurgical procedures
  • Fractionated stereotactic radiation therapy
  • Intensity modulated radiosurgery (IMRS)
  • Image guided radiation therapy (IGRT)

How It Works

Patient in Trilogy cancer treatment systemThe Trilogy system is built around an advanced medical linear accelerator, a machine that rotates 360 degrees around the patient to deliver radiotherapy treatments from many angles. The Trilogy accelerator has been enhanced for stereotactic applications that involve delivering higher doses of radiation to smaller areas over a shorter period of time.

The Trilogy system incorporates sophisticated technologies for shaping the radiation beam so that the dose of radiation is limited to the region of abnormality. By changing the beam shape over time while delivering the radiation, doctors achieve very fine control over how, and where, the radiation is administered.

  • Radiotherapy can be more effective at treating disease.
  • Side effects of treatment are reduced.
  • Smaller lesions can be treated more quickly, easily and effectively.
  • Patients can breathe naturally, reducing stress and increasing comfort.
  • Radiotherapy can be used to treat more different types of cancer, which means that more patients can be spared the invasive techniques of surgery and/or chemotherapy.
