Abstract

A medical assistance device, a system, and a method are provided for determining a deformation of a subject. Undisturbed image data of the subject and pose data of a robotic instrument are acquired. The medical assistance device is configured to determine the deformation of the subject due to a physical contact between the subject and the robotic instrument based on a biomechanical model. The undisturbed image data and a pose and/or motion of the robotic instrument are provided as input to the biomechanical model. The biomechanical model is predetermined or generated and/or updated based on a strain and/or a stiffness measured by a sensor.
