Abstract
The present invention relates to medical fluid injectors. An exemplary injector may include a drive ram that is adapted to interface with a plunger of a syringe. The drive ram may be equipped with an RF enabled pressure sensor that is configured to measure pressure exerted on the syringe plunger by the drive ram. In addition, the injector may include an RF circuit in RF communication with the pressure sensor of the drive ram. In some embodiments, the injector may include a controller in electrical communication with the RF circuit. The controller may be configured to adjust movement of the drive ram to alter the pressure exerted on the syringe plunger by the drive ram (i.e., the pressure measured by the pressure sensor).
