The invention relates to a coaxial and non-coplanar magnetic resonance guided head gamma knife radiotherapy system and a guiding method thereof. The system comprises a magnetic resonance imaging unit, a gamma knife irradiation unit, a treatment bed unit, a coordinate registration unit, a body surface optical tracking unit and a control system. The gamma knife irradiation unit is rigidly connected to the end face of the magnetic resonance imaging unit through a positioning interface, a positioning bed board is arranged on the treatment bed unit, a space reference mark is arranged on the positioning bed board, and the coordinate registration unit is connected between the magnetic resonance imaging unit and the treatment bed unit. The body surface optical tracking unit is mounted at the tail end of a positioning bed plate of the treatment bed unit; the control system is connected with the treatment bed unit, the gamma knife irradiation unit and the body surface optical tracking unit. Clear imaging of cranial soft tissue in a high-field-intensity environment can be realized, damage of external components to magnetic field uniformity and interference of an electron reflux effect caused by a high-intensity magnetic field to dose distribution are reduced, and radiotherapy precision is improved.

The invention belongs to the field of diagnosis and treatment in medical images, and particularly relates to a slitting type superconducting magnet and a coil framework thereof. Comprising a left inner framework; a right inner skeleton; a left outer skeleton; a right outer skeleton; a plurality of coil mounting grooves are formed in the left inner framework and the right inner framework; coil mounting grooves are respectively formed in the left outer framework and the right outer framework; and a gap for intraoperative observation or surgical operation is formed between the left inner skeleton and the right inner skeleton. The superconducting magnet can be combined with a gamma knife, a heavy ion or puncture ablation device and the like for use, so that the superconducting magnet can be synchronously carried out with treatment operations such as the gamma knife, the heavy ion or puncture ablation device and the like, real-time guidance and real-time quality observation are realized, and accurate positioning of diseases is facilitated; a patient does not need to move back and forth between the diagnosis equipment and the treatment equipment, extra pain borne by the patient is reduced, the treatment period is shortened, and the treatment efficiency is improved.
