IMRT (Intensity-Modulated Radiation Therapy)
IMRT is an advanced form of radiation therapy that delivers precise radiation doses to tumors while minimizing exposure to surrounding healthy tissues. It allows for varying intensity across different tumor regions, improving treatment effectiveness and reducing side effects. It is widely used in treating head and neck cancers, prostate cancer, and breast cancer.
IGRT (Image-Guided Radiation Therapy)
IGRT enhances the accuracy of radiation therapy by using imaging techniques like CT, MRI, or PET scans before or during treatment. This ensures that radiation is precisely targeted at the tumor, adjusting for any movement or changes in tumor size. IGRT is particularly beneficial for tumors in areas prone to movement, such as lung, prostate, and abdominal cancers.
Rapid Arc Therapy (Volumetric Modulated Arc Therapy - VMAT)
Rapid Arc is a highly advanced radiation technique that delivers treatment in a continuous rotational arc, ensuring faster and more precise radiation delivery. It significantly shortens treatment times while improving dose accuracy. This method is ideal for treating complex cancers like brain tumors, gynecological cancers, and pediatric tumors.
Stereotactic Radiotherapy (SRT) & Stereotactic Radiosurgery (SRS)
These techniques involve delivering high-dose radiation to tumors with sub-millimeter precision, often in a single or few sessions. SRS is commonly used for brain tumors and metastases, while SRT is applied to lung, liver, and spine tumors. This approach minimizes damage to surrounding tissues and provides excellent tumor control.
Adaptive Radiation Therapy (ART)
Adaptive therapy customizes treatment in real time by adjusting the radiation dose based on tumor shrinkage or anatomical changes during treatment. It is particularly useful for cancers that respond to therapy by reducing in size, such as head and neck cancers, lung cancer, and abdominal tumors.
MRI-CT/PET-CT Fusion-Based Planning
This technique combines MRI, CT, and PET scans to create a highly detailed 3D model of the tumor, allowing for precise radiation targeting. It is especially effective in treating tumors located in sensitive areas like the brain, spine, and prostate.
Whole Abdominal Radiotherapy (WAR)
WAR is used to treat cancers that have spread within the abdominal cavity, such as Desmoplastic Small Round Cell Tumor (DSRCT). The Rapid Arc technique is often utilized to ensure uniform radiation delivery with minimal toxicity to surrounding organs.
SBRT (Stereotactic Body Radiation Therapy)
SBRT is a high-precision technique used to treat small, well-defined tumors with minimal impact on nearby healthy tissues. It is highly effective for oligometastatic prostate cancer, lung tumors, and liver cancers, offering excellent local tumor control.
