Method for automatically generating blood vessel teaching aid by exploring box based on Monte Carlo algorithm

The invention relates to the technical field of medical teaching aids, in particular to a Monte Carlo algorithm-based exploration box blood vessel teaching aid automatic generation method, which comprises the following steps of: acquiring medical image data; initializing the exploration box based on the medical data to obtain an initialized box; performing Gaussian filtering on the initialized box to obtain a filtering box; performing global scanning on the filtering box to obtain a blood vessel control point; fitting the blood vessel control points through a spline to obtain a blood vessel curve; re-sampling the blood vessel curve to obtain blood vessel key points; calculating a threshold range of the initialization box, and reconstructing the blood vessel by using the blood vessel key point based on the threshold range to obtain a reconstructed blood vessel; creating a next exploration box based on the end point of the filtering box and re-initializing until the medical data is analyzed; a teaching aid for
