TomoTherapy(TOMO) - Helical tomographic radiotherapy is an advanced radiotherapy system that integrates three-dimensional CT images and leads to the reduction of intense radiation therapy (IG/IMRT). By performing daily MVCT scan imaging and registration, each patient is given the most accurate and high-quality individual treatment. The unique helical fracture treatment model and the fixed angle treatment model have expanded the clinical application and covered the radiotherapy of tumors in different parts of the body.
