A method is described for structurally individualized simulation of the introduction of a wall support element into a section of a tubular structure. To this end, image data of the interior of the section of the tubular structure are provided. A start point and an end point of the section of the tubular structure are then determined, and a lumen and a profile line of the tubular structure are determined between the start point and the end point. Furthermore, an individual elastic structure model for the section of the tubular structure is identified by adapting a tubular elastic initial model to the section of the tubular structure on the basis of the identified lumen and the profile line, and a tubular elastic wall support element model which is positioned inside the individual structure model is provided. In at least one embodiment, the wall support element model is then virtually expanded stepwise, a check for collisions between the wall support element model and the individual structure model being carried out in each expansion step. At the positions where a collision is identified, the wall support element model and the individual structure model are modified at least locally while taking into account the elasticity of the individual structure model. A method for driving an image display device, by using such a simulation method, and a simulation device are furthermore described.
