Radiation Therapy at Grapevine

The majority of our care is provided in an outpatient setting using customized therapies ranging from chemotherapy and radiation therapy to advanced technologies like immunotherapy, proton therapy, genetic testing, and genomic sequencing. Advanced treatments and best practices that come from a robust program of clinical trials and leading-edge research create the high caliber of care you’ll find at Texas Oncology.

Radiation Modalities

Texas Oncology-Grapevine offers a robust array of radiation modalities:

Imaging Equipment

  • >Echocardiography
    An echocardiogram (echo) is an ultrasound of the heart. It uses high-frequency sound waves to detect problems with the heart muscle, valves, or rhythm. Doctors may use this test during and after cancer treatment, such as radiation therapy to the chest, to look for possible heart damage, long-term side effects, or late effects that may occur months or years after cancer treatment.  Learn More.
  • >Positron Emission Tomography (PETCT)
    PET/CT is a powerful imaging tool that combines a PET (positron emission tomography) scan and a computed tomography (CT) scan. PET/CT is used to diagnose, stage, or restage your cancer, as well as evaluate the effectiveness of treatment. The images provide information about the location, nature, and size of your tumor. PET/CT is available at many locations, including Texas Center for Proton Therapy, whose PET/CT technology enables some of the fastest imaging available with the best image quality. The CT’s newer technology and faster scan times may result in less radiation exposure to patients. Its wider open design decreases claustrophobia and provides better access for larger patients and radiation therapy planning for cases requiring more space, such as breast cancer. Learn More.
    • >CT Simulation

      After the initial consultation and decision to use radiation treatment, the next session is usually a planning session, which is called a simulation. Simulation is used to determine the radiation treatment fields and most of the treatment planning. Of all the visits to the radiation oncology facility, the simulation session may actually take the most time.

      The CT simulator does not deliver radiation treatment, but instead allows the radiation oncologist and technologists to see the area to be treated. Images are obtained and transferred to the planning system where a virtual 3D image of the patient is created, and the treatment delivery plan is developed.

      For the simulation session, temporary marks are made on your skin with markers to identify the treatment areas. The room is periodically darkened while the treatment fields are being set. Alignment is critical during simulation and is facilitated by lasers mounted on the wall and ceiling. Special individually constructed immobilization devices may be used to help achieve this alignment. While you may see red lines of light, the low energy lasers are for alignment purposes only and you will not feel burning or anything else from the laser light.

      Once the aspects of the treatment fields are set, the technologist will take special simulation X-rays representing the treatment fields. In most centers, the patient is given multiple “tattoos,” which mark the treatment fields and replace the marks previously made with magic markers. These tattoos are not elaborate and consist of no more than pinpricks followed by ink, appearing like a small freckle. Tattoos enable the radiation technologists to set up the treatment fields each day with precision, while allowing you to wash and bathe without worrying about obscuring the marks that indicate where treatment will be delivered.

      Sometimes several simulation sessions are necessary in order to optimize treatment and are often performed prior to planned “boost” or “reduced field” treatments as part of the overall treatment plan. Learn More.
    • >Diagnostic CT imaging
      A CT scan can help doctors diagnose cancer and identify a tumor’s shape, size, and location. Learn More.
    • >Diagnostic PETCT imaging
      For some types of cancer, a PET/CT scan is a useful way to help find cancer and learn its stage. PET/CT imaging provides your doctor with a detailed 3D result showing abnormalities. These images provide information about how the cancer is affecting your body's functions and helps your doctor choose the best treatment. Learn More.

CT Simulation Techniques

  • >3D simulations
    Three-dimensional conformal radiation therapy (3D-CRT) is delivered by radiation beams positioned from different directions that are designed to match the shape of the tumor. This helps to reduce radiation damage to normal tissues and better kill the cancer by focusing the radiation dose on the tumor's exact shape and size. Learn More.

External Radiation Therapy

  • >Conventional 2D, 3D, electron treatments
    • Conventional 2D – Conventional (2D) radiation therapy refers to the technique of radiation therapy where treatments are planned by defining a limited number of beams with the boundaries delineated on patient X-rays. Conventional 2D radiation therapy is typically used for palliative treatment.
    • 3D Conformal Radiation – A type of external beam radiation therapy, 3D conformal radiation therapy combines images from CT, MRI, and PET scans to plan the radiation treatment. Software analyzes the images and helps direct radiation beams to conform to the tumor’s shape.
    • Electron Treatments – Electron therapy uses electrons directed to the outer layers of the skin to cover the surface of the body. It does not go into deeper tissues or organs.  
    Learn More.
  • >Intensity Modulated Radiation Therapy (IMRT)
    Intensity modulated radiation therapy (IMRT) is an advanced form of non-invasive radiation treatment enabling radiation oncologists to precisely target tumor cells. It uses computed tomography (CT) to create 3D images and treatment plans to deliver targeted radiation beams of varying intensity to cancerous tumors. By using image-guidance technologies, your radiation oncologist can localize your treatment and minimize damage to surrounding tissue. Learn More.

Image-Guided Radiation Therapy

  • >Electronic Portal Imaging Device (EPID)
    Electronic portal imaging devices (EPIDs) measure X-ray intensity transmitted through a patient during treatment. This measurement is transformed into a 2D digital image to accurately align the radiation beam to the tumor. Learn More.
  • >Onboard Imaging - Conebeam CT, Kilovotage imaging, Fluoroscopy
    Onboard imaging allows care teams to better align treatment to a tumor that may have a complex shape or move, which damage to healthy tissues.
    • Cone Beam Computed Tomography (CBCT) – Physicians use Cone Beam Computed Tomography (CBCT), which utilizes 3D volumetric imaging (vs. 2D X-ray images), to provide improved visualization, better patient positioning, and more precise treatment of cancerous tumors.
    • Kilovoltage Cone Beam Computed Tomography (kV-CBCT) – A type of board imaging, kilovoltage Cone Beam CT allows care teams to make adjustments to the X-rays that impact the intensity and quality of the image.
    • Fluoroscopy – Fluoroscopy is another medical imaging test that can be used in IGRT. An image of the area is created by sending an X-ray beam continuously through the body to create an image. Physicians can view the image on a monitor in real time to see the movement of internal organs.
