What is BS EN IEC 61828- Defining and measuring focussing for transducers about?
BS EN IEC 61828 provides definitions for the transmitted field characteristics of focusing and non-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 field characteristics of focusing and non-focusing transducers
- Specifies beam axis alignment methods appropriate for focusing and non-focusing transducers
BS EN IEC 61828 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. BS EN IEC 61828 shows how the characteristics of the transmitted field of transducers can 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.
BS EN IEC 61828 applies only to media where the field behavior 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 been used in scientific communications, system design, and description of the performance and safety of systems using these devices.
Note: BS EN IEC 61828 incorporates definitions from other related standards where possible, and supplies more specific terminology, both for defining focusing characteristics and for providing a basis for measurement of these characteristics.
Who is BS EN IEC 61828- Defining and measuring focussing for transducers for?
BS EN IEC 61828 on definitions and measurement methods regarding focusing for the transmitted fields are beneficial for:
- Electrical engineers
- Electricians and people working in the electrical department
- People who specialize in physics
Why should you use BS EN IEC 61828- Defining and measuring focussing for transducers?
Transducers are devices that are often employed in automation, measurement, and control systems. Many transducers have an input that is then converted to a proportional electrical signal.
Focusing transducers are essential in medical applications for obtaining high-resolution images, Doppler, and flow data and for concentrating ultrasonic energy at desired sites for therapy. BS EN IEC 61828 updates the user with specific definitions appropriate for describing the focused field from a theoretical viewpoint for transducers with known characteristics intended by design.
Other specific definitions included in BS EN IEC 61828, based on measurement methods, provide a means of determining focusing properties, if any, of a transducer of unknown field characteristics.
The measurement method and definitions provide criteria for determining if the transducer is focusing, as well as a means of describing the focusing properties of the field.
Beam axis alignment methods and field characterization measurements are for both focusing and non-focusing transducers.
Overall, BS EN IEC 61828 is helpful as it provides field characterization, specification, and measurement of field parameters for high-intensity therapeutic ultrasound (HITU) transducers and systems that can be helpful for your business.
