Fluid-containing structures can be localized and aspirated by using a specially-designed ultrasonic transducer with a central hole. A needle is directed through the hole and into the tissue. The path of the needle tip can be followed ultrasonically as it enters the fluid. The same transducer is used to monitor the procedure continuously while the fluid is aspirated.
