Radiation Modalities

Texas Oncology-Baylor Charles A. Sammons Cancer Center Radiation Oncology offers a robust array of radiation modalities:

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.
  • >4D CT scanning
    Four-dimensional computed tomography is a type of CT scanning which records multiple images over time. Images are mapped to the breathing cycle to give care teams more information about respiration and internal movement for treatment planning. Planning 4D-CT scans can be used to minimize target volumes for lung cancer radiotherapy. 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.
  • >Stereotactic Body Radiotherapy (SBRT)
    Stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT) are non-surgical procedures that deliver precisely-targeted radiation at very high doses with minimal damage to surrounding healthy tissue. SRS uses a computer-guided therapy system to treat tumors and other abnormalities of the brain. SRS is ideal for otherwise inoperable tumors, such as those that cannot be treated by traditional surgical methods. SBRT is used in areas of the body other than the brain to treat malignant or benign small to medium size tumors. Learn More.
  • >Stereotactic Radiosurgery (SRS)
    Stereotactic radiosurgery (SRS) and stereotactic body radiotherapy (SBRT) are non-surgical procedures that deliver precisely-targeted radiation at very high doses with minimal damage to surrounding healthy tissue. SRS uses a computer-guided therapy system to treat tumors and other abnormalities of the brain. SRS is ideal for otherwise inoperable tumors, such as those that cannot be treated by traditional surgical methods. SBRT is used in areas of the body other than the brain to treat malignant or benign small to medium size tumors. Learn More.
  • >Stereotactic Radiotherapy (SRT)
    Like stereotactic radiosurgery (SRS), stereotactic radiotherapy (SRT) uses a computer-guided therapy system to deliver large doses of radiation. However, instead of a single session, radiation is delivered on multiple days divided into several doses. Learn More.
  • >Total Body Irradiation (TBI)
    Total body irradiation (TBI) is a type of radiation therapy that is given to the entire body, often in combinations with high-dose anti-cancer drugs, in order to help prepare a patient for a stem cell transplant. TBI is given to kill any remaining cancer cells and to make room in the patient’s bone marrow for new blood stem cells to grow. Total body irradiation may also help prevent the body’s immune system from rejecting the transplanted stem cells. Learn More.
  • >Total Skin Electron Therapy (TSE)

    Total skin electron therapy (TSET) is a treatment for cutaneous T-cell lymphoma, a rare type of blood cancer. It works by delivering a specific amount of radiation all over the skin while minimizing radiation exposure to the rest of the body. TSET may be used as a stand-alone treatment or in combination with other therapies.

    Like other forms of radiation, TSET is delivered by a linear accelerator. During treatment, the patient stands in a variety of positions in front of the linear accelerator, while special monitors measure the exact dosage of radiation on various parts of the body. Custom shields help protect sensitive parts of the body, such as nails and eyes.

    Unlike traditional radiation therapies, in which radiation beams pass through the tumor and exit on the other side of the body, TSET uses electron-based radiation treatment to penetrate only a shallow portion of the patient’s body. This technique allows a patient’s skin to be treated without exposing the whole body to radiation.

  • >Volumetric Modulated Arc Therapy (VMAT): Rapid ARC

    Volumetric modulated arc therapy (VMAT) is a type of radiation therapy used to deliver highly-specific treatment doses, while minimizing damage to normal tissues. A linear accelerator moves around the patient 360 degrees to deliver the radiation to the tumor.

    • RapidArcTM – Varian RapidArcTM is an advanced form of intensity-modulated radiation therapy (IMRT) that allows radiation oncologists to send multiple doses of precise beams in the 3D shape of tumors. RapidArcTM uses computed tomography (CT) or other imaging technology to pinpoint tumors and guide the radiation beam around the patient.
    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.
  • >Exac Trac
    ExacTrac is an advanced imaging technology used to verify patient and tumor position at the time of treatment, allowing us to target only the tumor and spare the surrounding normal tissue. 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.
    Learn More.

Surface Guidance Radiation Therapy

  • > Vision RT
    Vision RT technology systems increase treatment accuracy and patient comfort during radiation therapy by using surface guided radiation therapy. It tracks the patient’s skin surface using 3D cameras and helps with motion management during treatment, which ensures the patient is in the intended position for treatment accuracy. 

Respiratory Gating

  • > Deep Inspiration Breath Hold Technique
    Deep inspiration breath hold (DIBH) is a technique used to minimize radiation doses to the heart over a course of therapy for breast cancer. During both simulation and treatment, the patient takes a deep breath and holds it for a designated amount of time while radiation is given, allowing for a decrease in radiation dose to the heart.
  • > Varian RGSC or RPM
    Varian respiratory gating for scanners (RGSC) or real-time position management (RPM) gives care teams the ability to accurately allow for tumor motion and patient breathing in treatment planning.

Brachytherapy Procedures

  • >High Dose Rate (HDR) Brachytherapy
    High dose rate (HDR) brachytherapy uses radioactive material inserted into applicators placed within body cavities or tissues to deliver a high dose of radiation precisely to the tumor. Learn More.
    • >Breast Cancer HDR- Mammosite, SAVI, Contoura

      High Dose Rate (HDR) internal radiation therapy utilizes radioactive material inserted into applicators within body cavities or tissues in close proximity to the tumor, allowing for a high dose of radiation to be delivered precisely to the tumor. HDR brachytherapy is a temporary implant conducted in an outpatient setting and minimizes treatment time. Imaging tools such as CT (computed tomography) verify the exact catheter or applicator placement, resulting in a radiation dose with one-millimeter accuracy that significantly spares radiation exposure to surrounding healthy tissue and critical organs. For breast cancer, several options are available. Your physician will discuss which the most appropriate option for you.

      • The SAVI™ applicator delivers a high daily dose of HDR brachytherapy via multiple catheters that allow clinicians to contour the radiation and protect nearby healthy tissue. This approach provides greater flexibility in the delivery of radiation.
      • The Contura™ balloon delivers a high daily dose of HDR brachytherapy via five channels for the radioactive source. These channels allow clinicians to shape the radiation and administer radiation only where it is needed, thus protecting healthy tissue. Treatment time is decreased to just five days versus up to seven weeks.
      • MammoSite® delivers a high daily dose of HDR brachytherapy to the area where breast cancer is most likely to recur after a lumpectomy. The radiation can kill any remaining cancer cells. MammoSite® works from inside the body via a discreet balloon catheter system implanted in the breast lumpectomy 
      Learn More.
    • >Gynecological HDR
      HDR internal radiation therapy is used to treat gynecologic cancers by delivering radiation internally and precisely targeting the tumor. This precision minimizes the impact on the surrounding healthy tissue and limits side effects. The radiation is delivered through an applicator that is inserted internally and is removed once treatment is complete. Treatment time is significantly reduced to three to six treatments that last 10 to 20 minutes each.  Learn More.
    • >Skin HDR
      Skin HDR internal radiation therapy is a convenient, effective treatment alternative with outstanding results and minimal side effects. A radioactive seed travels through an applicator and delivers a precise radiation dose directly to the target within one-millimeter accuracy. It achieves good to excellent cosmetic results and is a good treatment option for cancers around the eye and nose that are more difficult to treat surgically. It is typically administered two to three times per week for a total of six to 10 treatments. Treatment takes less than 10 minutes and is painless.  Learn More.
  • >Low Dose Rate (LDR) Brachytherapy
    Internal radiation is also referred to as brachytherapy. Internal radiation therapy delivers a higher dose of radiation directly to the cancerous area than external radiation treatments. Low dose rate (LDR) brachytherapy uses radioactive materials inserted into body tissue in close proximity to the tumor in a permanent or temporary application. Low dose rate (LDR) brachytherapy delivers lower dose rates of radiation over a longer period before becoming inert. This therapy is administered through long-term or short-term implants. Learn More.
  • >Prostate Seed Brachytherapy
    A type of brachytherapy radiation treatment, prostate seed implants are very small radioactive pellets permanently inserted into the prostate. They give off low doses of radiation over time and become inert. Learn More.

Radiation Information Systems

  • > Elekta MOSAIQ
    Elekta MOSAIQ® Care Management software helps manage all aspects of a radiation oncology program, keeping patient information easily accessible while simplifying complex treatment management, personalizing decision support, and reducing errors and wait times.
