Abstract
A bubble trap for use with an ultrasonic scanhead is described. The bubble trap is comprised of a reservoir chamber connected to the main chamber housing the ultrasound transducer. The reservoir chamber is connected via a channel which extends from the main chamber to an orifice in the volumetric center of the reservoir chamber. Thus, any bubble which flows up through the orifice into the reservoir chamber will be trapped there, and will thereby be removed from the main chamber.
