The present invention relates to computer-implemented medical method of verifying an expected deformation of an elastically deformable and actuator-adjusted medical fine-adjustment unit (1), the method comprising executing, on a processor of a computer, the steps of； —acquiring model data describing a model of the fine-adjustment unit (1), the model reflecting deformation properties of the fine-adjustment unit (1)； —acquiring actuator data describing an actuator position of at least one actuator coupled to the fine-adjustment unit (1)； —determining, based on the model data and the actuator data, target deformation data describing a target deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position； —acquiring actual deformation data describing an actual deformation of the fine-adjustment unit (1) caused by the at least one actuator at said actuator position； —determining, based on the target deformation data and the actual deformation data, verification data describing whether the target deformation corresponds to the actual deformation. The present invention further relates to a corresponding computer program causing a computer to perform such method, and a corresponding system comprising such a computer.
