2D Array Selection Guide

Single-Element Transducer Selection Guide

Our 2D Array Selection Guide will help you quickly find the right transducer for your specific needs.  We offer an extensive selection of standard 2D Arrays, which are listed in the large table below.   For single-element transducers, consult our Single-Element Transducer Selection Guide.

We can also produce custom single-element transducers and 2D arrays, optimized for your unique application.  If you have questions or need technical assistance, please feel free to contact us.

To Create Customized 2D Arrays

Use our proprietary Design Your Own (DYO) calculator to specify customized 2D array transducers tailored to your unique requirements.  The DYO lets you calculate changes in transducer output when you vary input parameters.  For your convenience, the DYO comes pre-populated with the parameters of model H-301, our most popular 2D array transducer.  Simply vary any of the parameters to specify your unique model.  If you need to modify any other 2D array transducer, select the DYO button below the transducer model name.  You can then modify the input parameters to your exact specifications.

  • To increase the focal steering field:
    • Reduce the frequency. When you reduce the frequency, the focal geometry increases.
    • Reduce the sub-element diameter. When you reduce the sub-element diameter, the focal intensity will decrease, as long as you keep the number of elements constant. When you reduce the sub-element diameter and increase the number of elements to increase the focal intensity, you will need a higher number of RF channels to operate the device.
  • To increase focal intensity:
    • Increase the frequency. When you increase the frequency, both the focal geometry and focal steering range decrease proportionately.
    • Maximize the sub-element area to 60% of the total aperture. This may require more discrete RF channels to offer improved steering range while meeting the focal intensity requirements.
    • It’s possible to exceed 60% sub-element to total area aperture with non-circular elements. Please contact Sonic Concepts’ technical support staff for support.

  • The calculator estimates the focal geometry (ellipsoid) and focal steering range down to -3 dB.
  • The calculator assumes a linear free field and is not indented to define acoustic performance with respect to grating lobes.
    • General practice uses randomization of elements to reduce grating lobe effects.  At lower frequency (<1 MHz), it is advised to randomize the element distribution to sustain focal intensity.  When randomizing, the sub-element-to-total-aperture ratio reduces to 50% or less.
    • The H-300 series used for HIFUPlex systems uses an Archimedean Spiral that is geometrically packed.  The steering range for this series of transducers has been designed to offer the greatest power density.  If you need to examine grating lobe performance, contact Sonic Concepts’ technical support staff for assistance.
  • The calculator does not anticipate error due to mode structures within the transducer structure.
  • The calculator assumes circular sub apertures dispersed about a total aperture without considering the arrangement type.
  • Limitations of the sub-aperture area will never exceed 60% of the total area of the aperture, since 60% is considered a geometrically packed array using circular elements.  If either the number of elements or the sub element diameter exceeds 60%, the calculator will present an error.
  • Our Transducer Power Output (TPO) can output 100 watts average power per channel.  Other constraints within the transducer will limit power operation to well below this figure.  Contact Sonic Concepts’ technical support to help define these conditions on a case-by-case basis.

To Select Standard 2D Arrays

The table below contains our complete catalog of standard 2D array models.  To select your optimal 2D array, use the drop-down menus under each parameter to input your specific project requirements.  The TSG automatically filters the displayed models to present only the 2D arrays that meet your exact specifications.
