摘要： An ultrasonic imaging apparatus has an array (10 or 100) of transducer elements (14 or 104) for transmitting ultrasonic signals into an object (12) to be analyzed through use of the transmitted signals reflected from the object and sensed by the apparatus. The transmitted signals have a first predetermined center frequency. The reflected signals sensed by the apparatus have a second center frequency less than the first center frequency as a result of signal attenuation by the object. A means (70, 62 or 150, 152-1 through 152-X) is connected to select a number of transducers (14 or 104) in the array (10 or 100) for transmitting and/or receiving the ultrasonic signals based on the second center frequency. Adjusting the number of transmitting and/or receiving transducers (14 or 104) with changes in frequency produced by signal attenuation gives improved image resolution under a wider variety of use conditions than with prior art ultrasonic imaging apparatus.

The unit comprises a connector for communicating with liquid in a sealed container, the connector having an exit orifice around which is secured one end of a primer tube. The other end of the primer tube is joined to a pooling conduit. The diameter of the primer tube is greater than the diameter of a drop of liquid released from the orifice and the diameter of the pooling conduit is no greater and preferably slightly less than the diameter of the drop of liquid. Multiple units can be joined to a common tube of enlarged diameter which leads into a pooling and dispensing container.
