常见问题: IGRT

Image Guided Radiation Therapy (IGRT) is the most advanced technology to track cancer 和 normal tissues. IGRT decreases radiation dose to normal tissue, decreases side effects 和 improves outcomes. This advanced technology allows radiation to be delivered to tumors with more precision than was traditionally possible.

Before the radiation beam is turned on, our physician's use Image Guidance technology to provide precise 和 exact information on the specific location of any soft-tissue or bony target. The ability to define a more precise location of the tumor means a smaller radiation field can be used, so there is less radiation damage done to normal tissue.

Most cancers will benefit from treatments that are more accurate 和 precise. Tumors of the prostate, brain 和 head 和 neck region are treated using IGRT to ensure that delicate tissues such as the rectum, urethra, spinal cord 和 salivary gl和s remain away from the higher dose of radiation that is delivered to the tumor.

When treating prostate cancer with IGRT, we see significant benefits. As the bladder fills 和 empties, the prostate moves, sometimes significantly. This means that the prostate will be in different positions for each day of radiation treatment. Our physicians use IGRT before the treatment is given to ensure a more precise delivery of radiation.

肺 和 breast cancers will benefit from IGRT 和 other technologies such as Respiratory Gating 和 放射 by taking breathing motion into consideration, 和 decreasing radiation doses to the lungs 和 heart. It has been shown that unnecessary radiation to these organs can create significant problems after treatment, such as secondary cancers.
