Unable to confirm complaint.Performed set-up procedure, and performed multiple injections, both wet and dry with varying flow rates,pressures and volumes.In all cases, the injection began when prompted(either from the control panel or remote), paused when prompted (control panel, remote, pendant) and complete after the programmed amount of contrast had been delivered.The system was left "armed" for differing lengths of time and observed.There was no indication of "self-injection" in any of the cases.All possible investigations were made on this system but no defect was found.All the subsystems of this injector has been changed as preventive action.
