Abstract
A system for delivery of a medium having ultrasound contrast enhancement agents therein to a patient includes a pressurizing device for pressurizing the medium, a fluid path connecting the pressurizing device to the patient and a concentration sensor in communication with the fluid path. The concentration of the contrast enhancement agents is measured by the concentration sensor during injection of the medium into the patient to assist in controlling the delivery system and/or an imaging procedure.
Claims14
A method of preparing a medium with contrast enhancement agents therein, the method comprising the step of measuring a property of the contrast enhancement agents during preparation of the medium to assist in properly preparing the medium.
A system for preparing a medium with contrast enhancement agents therein, the system comprising:
- a container including the medium;
- an agitation mechanism operably associated with the container for agitating the medium;
- and
- a sensor adapted to measure a property of the contrast enhancement agents in the container.
A method of delivering a medium with contrast enhancement agents therein into a patient, the method comprising:
- measuring a property of the contrast enhancement agents;
- and
- controlling at least one of the delivery of the contrast enhancement agents or an imaging procedure carried out in conjunction with delivery of the contrast enhancement agents by selective destruction of contrast enhancement agents.
