该方法简单、实用,能够快速地将体数据中最显著的特征展示给用户,因此广泛

This method is simple and practical, and can quickly show the most significant features in volume data to users, so it is widely used in medical fields, such as angiography. Although the MIP algorithm can meet the specific needs of users to a certain extent, there are still the following Two shortcomings: (1) the resulting image drawn is only composed of the maximum density value, and the background compensation information is lost, so the rendering result lacks depth perception; (2) the drawn result image lacks feature orientation information, that is, the feature is not illuminated. , Insufficient shape perception.

The method is simple, practical and can quickly show the most prominent features of body data to the user, so it is widely used in medical fields such as angioscopy. Although the MIP algorithm can meet the specific needs of the user to some extent, there are two shortcomings: (1) the resulting image is composed only of the maximum density value, the background compensation information is lost, so the drawing result lacks depth perception;
