Apparatus for applying impedence matching fluid for ultrasonic imaging

摘要

An apparatus is disclosed for applying impedance matching gel to an ultrasonic transducer head of an imaging device for application to a patient. The apparatus comprises: a reservoir for containing the impedance matching gel; a heater for heating the impedance matching gel in the reservoir to a predetermined temperature; a conduit for conveying the impedance matching gel from the reservoir to the ultrasonic transducer head; a pumping arrangement for supplying the heated impedance matching gel from the reservoir, via the conduit, to the ultrasonic transducer head for application to the patient; and a low gel sensing system for indicating when the amount of gel in the reservoir drops below a predetermined quantity to prevent overheating of the gel.
