Abstract: A fluid injector system includes a powered fluid injector, a connection port configured to receive a single-use disposable set having tubing connected to a fluid inlet port at a first end and connected to a waste outlet port at a second end, and a detector associated with the connection port and configured to generate a signal in response to a sonic, infrasonic, or ultrasonic wave emitted from the single-use disposable set during a priming operation of the single-use disposable set. In some examples, the detector is configured to generate a signal if the frequency of the wave emitted from the single-use disposable set is outside a predetermined range of frequencies corresponding to a predetermined range of frequencies of air expelled from the tubing. A method for detecting the multiple uses of a single-use disposable set connected to a fluid injector system is also provided.
