1. Technical Features and Performance Introduction of the Equipment

（1）The dose intensity is 3-4 times that of previous radiotherapy systems;

（2）The treatment speed has reached the current limit of high-energy radiation therapy equipment (IEC standard limit = 1 minute / 360 degrees);

（3）Physical precision: Equipped with an ultra-high resolution 2.5mm multileaf collimator, and circular collimator options with the smallest aperture reaching 4mm;

（4）Dose precision: The MAESTRO control system has a dose output control precision of 0.04MU or better;

（5）Position precision: Unique four-dimensional imaging guidance mode for target tracking, innovatively introducing the Calypso radiosurgery navigation systems radiation-free GPS beacon technology, which solves the technical barriers of additional radiation doses and real-time tracking limitations of previous tracking technologies.

2. Clinical Applications of the Equipment

Clinically, it has successfully carried out stereotactic radiosurgery (SRS) for intracranial and spinal lesions, and stereotactic body radiation therapy (SBRT) for extracranial lesions, especially achieving breakthrough progress in the radical treatment of lung cancer, liver cancer, prostate cancer, and pancreatic cancer. Clinical applications include intracranial lesions, head and neck lesions, thoracic lesions, abdominal lesions, pelvic lesions, and complex lesions.
