Abstract

An ultrasound probe for diagnostic medical ultrasound imaging, including an ultrasound transducer and a circuit having a plurality of states to limit the use of the ultrasound probe. Ultrasound probe use can be limited based on a unique identification number (e.g., selected by means of electrically programmable fuses) assigned to each ultrasound probe. Alternatively, the ultrasound system software monitors and updates the number of times that the ultrasound probe has been used. Another aspect of the invention is directed to an ultrasound system, including an ultrasound probe with multiple states, a circuit to program and to receive state data from the ultrasound probe and interpret the state data, and a cable to communicate state data between the ultrasound probe and the processor. Another aspect of the invention is directed to a method for using a limited use ultrasound probe, including the steps of determining the state of a circuit in the limited use ultrasound probe and determining if the ultrasound probe can be used.
