A wireless transmitter is disposed on the shaft and provides wireless communication between a Hall sensor and a signal processing device. At least one magnet is fixed proximate the syringe housing.

Volume monitoring systems

A method of determining an amount of medium injected into a patient includes receiving an injection signal from a sensor associated with an injection syringe. A diversion signal is received from a sensor associated with a diversion reservoir. The amount of medium injected is determined based at least in part on the injection signal and the diversion signal.
