What is the TOMO Helical Tomotherapy System?
The TOMO helical tomotherapy system introduced at our hospital integrates IMRT (intensity-modulated radiotherapy), IGRT (image-guided intensity-modulated radiotherapy), and DGRT (dose-guided intensity-modulated radiotherapy). Its innovative design seamlessly combines a linear accelerator with a helical CT, overcoming many limitations of conventional accelerators. Under CT guidance, it delivers 360-degree focused tomographic irradiation of tumors, providing highly efficient and precise treatment for patients with malignant tumors.
Main Indications of TomoTherapy
TomoTherapy can be applied to tumors of any size and location throughout the body. It is particularly advantageous for complex shapes, long target volumes, multiple target regions, and multiple metastatic lesions. Specific indications include:
1. Thoracic tumors: breast cancer, lung cancer, esophageal cancer
2. Abdominal and pelvic tumors: cervical cancer, gastric cancer, prostate cancer, rectal cancer, pancreatic cancer, liver cancer
3. Head and neck tumors: nasopharyngeal carcinoma, intracranial tumors (including multiple brain metastases), thyroid cancer, oral cancer, pharyngeal cancer
4. Other complex or special types: multiple metastatic lesions, pediatric tumors (such as medulloblastoma requiring whole-brain and full-spine irradiation), spinal metastases, soft tissue sarcoma, multiple myeloma, tumors at multiple body sites, benign lesions (e.g., hemangiomas, keloids)
Notably, TomoTherapy is particularly effective for tumors with complex structures or irregular shapes. For advanced-stage tumors, large volumes, or multiple metastases, TomoTherapy often represents a superior treatment option. Its unique helical tomotherapy mode can cover a maximum treatment length of 135 centimeters, allowing single-session irradiation for multiple metastases or tumors at multiple body sites.
Advantages and Key Features of TomoTherapy
1. High Precision Perfect integration of image guidance and helical intensity-modulated radiotherapy, achieving submillimeter accuracy and dose-sculpting irradiation of tumors.
2. Wide Treatment Range The 360-degree helical treatment mode can cover up to 135 cm, allowing multiple metastatic lesions to be treated in a single session.
3. High Treatment Quality Excellent conformity and dose uniformity in the target area, with clinical studies demonstrating significant improvement in patient survival.
4. Normal Tissue Protection Comprehensive beam modulation capability delivers sufficient tumor dose while optimally sparing surrounding normal tissues.
5. High Intelligence Integrated image guidance, dose guidance, and adaptive radiotherapy functionalities enable fully intelligent workflow management.
6. High Efficiency The latest CT-TOMO technology allows single-site imaging in 10 seconds, enabling treatment of over 100 patients per day.
7. Comfortable Treatment Experience Large bore design reduces claustrophobia, with extremely low noise for a comfortable and quiet treatment process.
8. Well-Validated Clinically International phase III randomized controlled trials demonstrate that TomoTherapy preserves 10-year cardiopulmonary function in breast cancer patients significantly better than conventional radiotherapy.
