Radiation Therapy at Pasadena

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-Pasadena offers a robust array of radiation modalities:

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.

  • >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.

  • >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.
