标准简介：This International Standard
− provides definitions for the transmitted field characteristics of focusing transducers for
applications in medical ultrasound;
− relates these definitions to theoretical descriptions, design, and measurement of the
transmitted fields of focusing transducers;
− gives measurement methods for obtaining defined characteristics of focusing transducers;
− specifies beam axis alignment methods appropriate for focusing transducers.
This International Standard relates to focusing ultrasonic transducers operating in the
frequency range appropriate to medical ultrasound (0,5 MHz to 40 MHz) for both therapeutic
and diagnostic applications. It shows how the characteristics of the transmitted field of
transducers may be described from the point of view of design, as well as measured by
someone with no prior knowledge of the construction details of a particular device. The
radiated ultrasound field for a specified excitation is measured by a hydrophone in either a
standard test medium (for example, water) or in a given medium. The standard applies only to
media where the field behaviour is essentially like that in a fluid (i.e. where the influence of
shear waves and elastic anisotropy is small), including soft tissues and tissue-mimicking gels.
Any aspects of the field that affect their theoretical description or are important in design are
also included. These definitions would have use in scientific communications, system design
and description of the performance and safety of systems using these devices.
This standard incorporates definitions from other related standards1 where possible, and
supplies new, more specific terminology, both for defining focusing characteristics and for
providing a basis for measurement of these characteristics.
