Problems encountered in ultrasonic diagnostics can be conventionally split into three
groups. The first group includes pure medical problems, the second group is connected
with engineering problems and equipment, and the third group deals with physical problems.

The medical aspects of ultrasonic diagnostics are discussed in the major part of books
devoted to this subject. Its engineering aspect is also well studied. At the same time, the
analysis of related physical problems is almost completely absent in the contemporary
monographic literature. For this reason, to the authors’ point of view, the proposed,
certainly not completely perfect, book devoted to the investigation of the physical problems
of medical ultrasonic diagnostics deserves certain attention of the readers.
