An imaging system comprising a disposable part (1) comprising a camera device (5), said disposable part arranged to be suitable for allowing said camera device to be inserted into a body cavity, a reusable control module (8) in communication with said disposable part, said reusable control module comprising a display which displays image signals from the camera device in the disposable part, a timing device which generates time of use data of the disposable part, said time of use data representing the amount of time which the disposable part is in use, and said imaging system being arranged to prevent use of the disposable part if the time of use of the disposable part reaches a predefined level. The disposable part further comprises a non-volatile memory component which stores time of use data generated by said timing device and in that said reusable control module is arranged to continuously monitor the time of use data stored in the non-volatile memory component of the disposable part and to stop displaying image signals from the camera in the disposable part when the time of use data stored in the non-volatile memory component reaches said predefined level. In this way an imaging system is provided which is able to prevent using a disposable part which has been used on one patient on another patient.
