title: An approach to digital signal processing for ultrasonics research.
abstract: The increasingly sophisticated techniques for the extraction of information from ultrasonic data entail a corresponding increase in complexity of the software used. An interactive signal and image processing package, called TWODIMSY, has been developed at the Ultrasonics Institute to allow non-programmers an entry to digital signal processing, and to simplify the task of staff involved in programming. We present an outline of the design considerations which shaped TWODIMSY, and a brief history of its ancestors. A detailed description of the package is given, including the type of computational facilities provided and the approach taken to solve the problems of data storage, operator interface and documentation.
