Three-dimensional (3D) treatment is a technology that allows radiation therapy beams to be shaped exactly to the size of a tumor. The tumor is able to be visualized in three dimensions so that the radiation beams paths and shapes can optimized treat cancer but minimize causing side effects to normal organs.
Many cancers of the body (e.g. lung cancer) move during treatment as a patient breathes. Four-dimensional treatment planning and delivery enables radiation treatment to adjust to movements during therapy. In addition, 4D treatment is used to protect critical areas of the body during radiation treatment (e.g. shield heart during breast cancer treatment).
Electron beam treatment is different than standard X-ray treatment as it only penetrates a few centimeters into the body and then stops. It is the preferred treatment for superficial tumors or skin cancers.
High Dose Rate (HDR) Brachytherapy involves the temporary placement of radioactive sources within the body to deliver high-doses of radiation to localized areas in a manner that helps protect and spare healthy tissue. At Banner MD Anderson Cancer Center, HDR Brachytherapy is performed on an outpatient basis and may be used to treat gynecologic, breast, lung and skin cancers.
Image-Guided Radiation Therapy (IGRT) is a specialized radiation delivery method that accounts for the movement of tumors in organs, such as the lungs, that move naturally inside the body. At Banner MD Anderson, IGRT uses ExacTrac® and Cone Beam CT to ensure the exact placement and delivery of radiation, regardless of movement.
Intensity-Modulated Radiation Therapy (IMRT) is a type of highly conformal radiotherapy that uses computer-generated planning to direct multiple radiation beams of differing intensities to the tumor being targeted for treatment. The precision of these beams makes it is possible to deliver higher doses of radiation than with conventional radiation therapy while minimizing the impact on healthy tissue.
Stereotactic Body Radiation Therapy combines the advanced 3-dimensional or Intensity-Modulated Radiation Therapy (IMRT) treatment techniques and Image-Guided Radiation Therapy (IGRT) to provide targeted high dose radiation delivery in just a few treatment sessions.
Stereotactic radiosurgery is precise, targeted, high dose treatment that is delivered in just one treatment. This technique is mainly used for brain and spine tumors and utilizes the most advanced image-guidance and treatment planning systems available.
Volumetric Modulated Arc Therapy (VMAT) uses a form of highly conformal Intensity-Modulated Radiation Therapy (IMRT) computerized planning to treat patients with a rotational arc therapy that rotates around the patient while the treatment beam is on. The SmartArc® VMAT technology enables Banner MD Anderson Cancer Center patients to receive very complex treatments in just a few minutes, which enhances comfort and minimizes excessive tumor movement during treatment.
