1. A method for detecting installation of a collimator of radiotherapy equipment, comprising:
acquiring a projection to be detected of a beam passing through the collimator and an isocentric plane of the radiotherapy equipment in sequence on a ray detector; and
comparing the projection to be detected with a reference projection, and determining an installation deviation of the collimator of the radiotherapy equipment based on a deviation between the projection to be detected and the reference projection.
