Sophisticated Techniques Add Precision to Radiation Therapy Treatments
Scott & White radiation oncologists use state-of-the-art technology and advanced techniques to help ensure that your radiation therapy targets the tumor, while sparing surrounding healthy tissue. Ask your doctor about which of the following techniques will be most beneficial to treating your tumor.
Image Guidance Makes Targeting Tumors More Precise
At Scott & White, we use Image-Guided Radiation Therapy (IGRT) during the course of our radiation oncology treatments in areas of the body that are prone to movement. IGRT is the use of frequent imaging during your radiation therapy treatment to ensure absolute accuracy of treatment.
IGRT is used with the following external-beam radiation therapies:
- Intensity-Modulated Radiation Therapy (IMRT)
- Three-Dimensional Conformal Radiation Therapy (3DCRT)
- Stereotactic Radiotherapy
Benefits of IGRT
- Patient and tumor motion tracked with the use of image guidance
- Radiation beam adjusted in response to current tumor image to maintain accuracy and reduce likelihood of harming nearby tissue
- Helps target tumors to sub-millimeter accuracy
- Features computerized robotic delivery and stereotactic localization imaging
- Requires an imaging series, which is transferred to computer, before treatment begins

Respiratory Gating Monitors Your Tumor as You Breathe
Radiation therapy for tumors may include an advanced imaging technique called respiratory gating. During your radiation therapy session, respiratory gating monitors your tumor as you breathe, resulting in greater accuracy of the treatment.
Benefits of respiratory gating include:
- Uses infrared tracking cameras and reflective markers to mark respiratory movement
- Uses a 4-D, highly exact CT scan, tracking your tumor movement as your lungs expand and contract, which slightly alters the location of your tumor
- Provides a sharp, clear tumor image so that your radiation oncology team can precisely plan and administer your treatment
- Can predict your breathing pattern, accommodating for coughing, sneezing and changes in respiration
- Accurate to 100 milliseconds beam on time
- Computer-controlled radiation beam starts and stops, responding precisely to your respiratory cycle as you inhale and exhale, minimizing damage to surrounding healthy tissues
Abdominal Compression Helps You Stay Still During Treatment
At Scott & White, radiation therapy for cancer may include the use of an abdominal compression device for areas of the body that are prone to movement.
Advantages of abdominal compression:
- Ensures proper positioning during the course of treatment
- Keeps your body and your tumor still during treatment
- Increases effectiveness of radiation therapy, allowing X-ray beam to hit tumor more accurately
- Decreases side effects often associated with radiation therapy
