Abstract
An ultrasonographic exposure apparatus is disclosed. An ultrasound transducer is positioned in a reservoir so that it is immersed in a transport liquid within the reservoir. An ultrasonographic element is positioned in contact with the transport liquid, and a damper is located to form an interface with the transport liquid adjacent the ultrasonographic element remote from the ultrasound transducer.
Claims20
An ultrasonographic exposure apparatus comprising
- a reservoir for an ultrasonic transport liquid,
- an ultrasound transducer positioned to be immersed in the transport liquid,
- means for supporting an ultrasonographic element within the transport liquid, and
- a damper located adjacent the ultrasonographic element remote from the ultrasound transducer to form an interface with the transport liquid within said reservoir.

An ultrasonographic exposure apparatus comprising
- a first reservoir for a first transport liquid,
- an ultrasound transducer positioned to be immersed in the first transport liquid, and
- an ultrasound reception unit positioned in contact with the first transport liquid to receive ultrasound from said transducer, comprising
- means forming a second reservoir for a second transport liquid including ultrasonically transmissive means forming at least one wall portion of said second reservoir,
- means for supporting an ultrasonographic element within said second reservoir adjacent said ultrasonically transmissive means,
- a damper located to form an interface with the second transport liquid adjacent a major surface of the ultrasonographic element remote from said transmissive means, and
- means cooperating with said second reservoir forming means and said damper to form an exposure chamber within the second transport liquid.

An ultrasonographic exposure apparatus comprising
- a first reservoir for a first transport liquid,
- an ultrasound transducer positioned to be immersed in the first transport liquid, and
- an ultrasound reception unit positioned in contact with the first transport liquid to receive ultrasound from said transducer, comprising
- a second reservoir for a second transport liquid including rigid walls cooperating with a flexible, ultrasound transmissive membrane forming at least a portion of a bottom wall of said second reservoir,
- a damper partially immersed in the second transport liquid positioned above a separate ultrasonographic element to be exposed which is, in turn, positioned above said ultrasound transmissive membrane,
- an ultrasound absorptive layer interposed between the ultrasonographic element and said damper, and
- means for controlling the flow of the second transport liquid in contact with the ultrasonographic element adjacent said ultrasound transmissive membrane.
