Claim:
1. A syringe system comprising: a syringe body comprising a proximal open end and at least one distal discharge outlet, the syringe body for housing a liquid substance to be discharged via the at least one discharge outlet; a syringe shield covering at least a portion of the syringe body; a plunger positioned in the syringe body and forming a seal with an inner wall of the syringe body; an automatic injection system comprising an injector piston configured to be received by the proximal open end and to engage the plunger to cause the plunger to move within the syringe body; at least one position sensor measuring at least a position of at least one of the plunger and the injector piston in the syringe body; at least one radiation sensor positioned within the injector piston and measuring radioactivity of the liquid substance within the syringe body; and a computing device in communication with or part of the automatic injection system and in communication with the at least one position sensor to receive position information about at least the position of at least one of the plunger and the injector piston in the syringe body and with the at least one radiation sensor to receive measurements from the at least one radiation sensor measuring the radioactivity of the liquid substance to determine, using the computing device, an injection volume of the liquid substance based on the position information received from the at least one position sensor and the radioactivity of the liquid substance received from the at least one radiation sensor.
