External-Beam Radiation Therapy

Targeted External Radiation for Tumors in the Brain, Breast, Colon, Liver, Lung, Pancreas, Prostate, and More

External-beam radiation therapy delivers high-energy X-ray beams at your tumor from an outside source.

These powerful X-rays are carefully planned to destroy cancer cells without damaging surrounding healthy tissues by a team of:

  • Radiation oncologists
  • Medical dosimetrists
  • Medical radiation physicists

Benefits of external-beam radiation therapy include:

  • No incisions and no cutting
  • No blood loss
  • No risk of infection
  • No or limited hospital stay required
  • No risk of radioactivity to you or others

Types of External-Beam Radiation Therapy

Scott & White offers the following external-beam radiation therapy options:

Scott & White uses Image-Guided Radiation Therapy (IGRT) and other sophisticated techniques to help maximize the accuracy of your treatment. Find out more »

  • Intensity-Modulated Radiation Therapy (IMRT)
  • Three-Dimensional Conformal Radiation Therapy (3DCRT)
  • Stereotactic Radiotherapy

Your physician team will discuss which option is best for you.

Intensity-Modulated Radiation Therapy (IMRT)

Scott & White offers Image-Modulated Radiation Therapy (IMRT), an advanced form of radiation therapy using computer-generated images to guide multiple beams of various intensity aimed from many angles.

  • Uses a computer-controlled medical linear accelerator to control intensity and volume of X-ray beams
  • Utilizes image-guided, high-energy X-ray beams stop to tumor growth, and in some cases, shrink or destroy your tumors
  • Conforms X-ray beams precisely to the 3-D shape of your tumor, minimizing damage to surrounding healthy tissue
  • Breaks up the X-ray beams into “beamlets,” which are then adjusted and controlled individually, allowing for precise and exact targeting of your tumor
  • Requires careful and exact planning, including an imaging series before treatment can begin
  • Generally requires multiple 15- to 45-minute treatments over four to six weeks

Three-Dimensional Conformal Radiation Therapy (3DCRT)

Scott & White offers 3-Dimensional Conformal Radiation Therapy (3DCRT), a form of radiation therapy using a 3-D picture of your tumor and a high dose of radiation.

  • A conventional form of radiation therapy
  • Uses image-guided, high-energy X-ray beams to stop tumor growth, and, in some cases, shrink or destroy your tumor
  • Conforms to the 3-D shape of your tumor, reducing damage to surrounding healthy tissues
  • Generally requires multiple 15- to 45-minute treatments over four to six weeks

Stereotactic Radiotherapy Using the Novalis Tx Radiosurgery Platform

This form of external-beam radiation therapy is highly precise. Because of that, we are able to deliver much higher doses of radiation to your tumor than conventional radiotherapy, while sparing surrounding healthy tissue. Scott & White offers the following types of stereotactive radiotherapy:

  • Stereotactic Radiosurgery
  • Fractionated Stereotactic Radiotherapy
