IGRT stands for Image-Guided Radiation Therapy. It is an advanced radiation therapy technique used in the treatment of cancer. IGRT combines radiation treatment with real-time imaging technology to precisely target and deliver radiation to cancerous tumors while minimizing damage to surrounding healthy tissues.
The main goal of IGRT is to improve the accuracy of radiation therapy by accounting for the natural movement and changes in the position of tumors and organs within the body. Tumors can shift slightly during treatment due to factors such as breathing, organ movement, or bladder or rectal filling. IGRT helps in addressing these challenges by providing frequent imaging before or during treatment to guide radiation delivery.
Here's how IGRT generally works:
Imaging: Various imaging techniques such as X-rays, computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound are used to capture detailed images of the tumor and surrounding structures.
Target Localization: The acquired images are compared to the initial treatment planning images or reference images to determine any changes in the position, size, or shape of the tumor.
Real-Time Monitoring: During the actual treatment, real-time imaging is often used to monitor the position of the tumor and surrounding healthy tissues, ensuring that the radiation beam is accurately delivered to the intended target.
By integrating imaging and treatment delivery, IGRT enables radiation oncologists to deliver higher doses of radiation to the tumor while sparing nearby healthy tissues, thus increasing treatment effectiveness and reducing side effects.
IGRT is commonly used for tumors in areas prone to movement or those affected by daily anatomical changes, such as lung, liver, prostate, and abdominal cancers. The specific IGRT techniques and equipment may vary depending on the medical facility and the type of cancer being treated. It is always best to consult with a radiation oncologist or a medical professional for specific information related
