Acoustic tags — are small sound emitting devices that allow the detection and/or remote tracking of fish in three dimensions. Commonly used to monitor the behavior of fish, studies are conducted in lakes, rivers, tributaries, estuaries and at sea. Acoustic tag… … Wikipedia
Beam tracing — is a derivative of the ray tracing algorithm that replaces rays, which have no thickness, with beams. Beams are shaped like unbounded pyramids, with (possibly complex) polygonal cross sections. Beam tracing was first proposed by Paul Heckbert and … Wikipedia
Acoustic targeted drug delivery — (ATDD) is a method that uses ultrasound energy to enhance the transport of molecules into and/or across specific tissues. Generally this class of ultrasound energy falls under the class of therapeutic ultrasound, and ranges in ultrasonic… … Wikipedia
