1. An error calibration method of radiotherapy equipment comprising an imaging system, wherein an imaging body disposed within a preset distance range of an isocenter of the radiotherapy equipment is adopted for error calibration of the radiotherapy equipment, and the error calibration method comprises:

  • imaging the imaging body through the imaging system to obtain an actual image of the imaging body;

    determining an image deviation between the actual image and a theoretical image of the imaging body, the theoretical image being obtained in advance based on a theoretical position of the imaging system and a spatial position of the imaging body in the radiotherapy equipment; and

    determining a system error of the imaging system based on the image deviation.
