Tomotherapy treatment under Dr. Vineet Nakra
Tomotherapy
Tomotherapy is a type of radiation therapy that uses a helical radiation delivery system that integrates a linear accelerator and CT technology. It can deliver accurate and high-quality image-guided intensity-modulated radiation therapy (IG-IMRT) from multiple 360-degree rotations around the patient as the treatment table moves. It can also deliver radiation at fixed angles (TomoDirect) for certain cases. Tomotherapy can treat tumors anywhere in the body with high precision and conformality, while minimizing the dose to healthy tissues.
Tomotherapy can be used for different purposes, such as:
- To cure cancer or prevent it from coming back (curative tomotherapy)
- To shrink a tumor before surgery or radiation therapy (neoadjuvant tomotherapy)
- To destroy any remaining cancer cells after surgery or radiation therapy (adjuvant tomotherapy)
- To slow down the growth of cancer or relieve symptoms (palliative tomotherapy)
Tomotherapy can be used alone or with other treatments, such as surgery, chemotherapy, hormone therapy, immunotherapy, or targeted therapy. Tomotherapy can be used for a wide range of cancer types and stages, such as:
- Head and neck cancers
- Prostate cancer
- Breast cancer
- Lung cancer
- Brain tumors
- Spinal tumors
- Gynecological cancers
- Pediatric cancers
Uniqueness of tomotherapy
Tomotherapy is unique because it combines three main features that make it an advanced radiation therapy modality:
- Integrated daily CT imaging: Tomotherapy uses CT technology to generate clear and high-fidelity images of the tumor and surrounding tissues before each treatment session. This allows for accurate alignment of the patient and verification of the tumor position and shape. It also enables adaptive planning to account for any changes in the tumor size, shape, or location during the course of treatment.
- Continuous delivery of radiation from multiple 360-degree rotations: Tomotherapy delivers radiation from a rotating gantry that moves around the patient as the treatment table moves through the bore. This creates a helical pattern of radiation delivery that covers the entire target volume with thousands of precise beams. The beams are shaped by a binary multi-leaf collimator (MLC) that modulates the intensity of each beamlet independently. This enables dose painting to maximize the dose to the tumor and minimize the dose to organs at risk (OARs).
- Advanced dose-delivery capabilities: Tomotherapy can deliver image-guided intensity-modulated radiation therapy (IG-IMRT) that conforms to the tumor shape and avoids healthy tissues. It can also deliver 3D conformal radiation therapy (3DCRT), stereotactic body radiation therapy (SBRT), and stereotactic radiosurgery (SRS) for different clinical indications. Tomotherapy can treat very long or complex volumes without a need to abut fields in the longitudinal direction. It can also treat multiple targets in different locations in one session.
Tomotherapy is a state-of-the-art radiation therapy technique that offers high precision, conformality, and adaptability for treating tumors anywhere in the body. It integrates CT imaging with helical or fixed-angle radiation delivery to achieve optimal dose distribution and tumor control. It can be used for various purposes and cancer types, depending on the patient's condition and treatment goals.
