摘要： This processing method provides the ability to process a volume mode with an object intended to be added to or subtracted from said model. The volume model includes points arranged according to a spatial grid in a first reference system, each point being assigned an intensity value. The object has points positioned in a second reference system that is distinct from the first reference system.The method includes the calculation, for each point of the object, of an image point in the first reference system using a transfer function.The method further includes the modification of the intensity of points of the volume model by applying a correction function associated with each image point, the value of the correction function at a point of the volume model being dependent on the position of said point relative to said image point with which said correction function is associated.
