Summary:The invention provides a method for adjusting the shape and size of a BNCT neutron collimator. The method comprises the following steps: carrying out three-dimensional modeling on a leading-out duct of the BNCT neutron collimator; importing into finite element analysis software, defining material parameters and boundary parameters, carrying out grid division, and carrying out finite element analysis; adjusting internal structure parameters of the BNCT neutron collimator according to a finite element analysis result, and updating the adjusted internal structure parameters to the established three-dimensional model to obtain an updated three-dimensional model; performing finite element analysis on the updated three-dimensional model, and outputting the neutron collimation degree and the energy distribution diagram of the BNCT neutron collimator; adjusting the shape and the size of the BNCT neutron collimator according to the output neutron collimation degree and the energy distribution diagram of the collimator
