Area of Science:

  • Acoustic Metamaterials
  • Ultrasonic Transducer Technology
  • Biomedical Imaging Systems

Background:

  • High-frequency ultrasound systems require precise acoustic focusing for advanced imaging.
  • Traditional focusing elements can be complex and expensive to fabricate.
  • Integration with piezoelectric micromachined ultrasonic transducer (PMUT) arrays is crucial for array-based imaging.

Purpose of the Study:

  • To develop and evaluate simple, low-cost acoustic lenses for high-frequency ultrasound applications.
  • To assess the suitability of Polymethyl methacrylate (PMMA) and Polydimethylsiloxane (PDMS) for 20 MHz acoustic lens fabrication.
  • To demonstrate effective ultrasonic focusing when integrated with a PMUT array.

Main Methods:

  • Fabrication of Fresnel and convex acoustic lenses using PMMA and PDMS materials.
  • Evaluation of lens performance through axial and lateral beam measurements.
  • Pulse-echo testing in the focal region to assess echo response and focusing quality.

Main Results:

  • Successfully fabricated low-cost PMMA and PDMS lenses suitable for operation around 20 MHz.
  • Demonstrated well-defined acoustic focus and stable echo response from both lens designs.
  • Confirmed compatibility and effective focusing when integrated with a PMUT array.

Conclusions:

  • Simple, low-cost PMMA and PDMS lenses are feasible for high-frequency ultrasonic focusing.
  • These lenses are suitable for demanding applications, particularly with PMUT arrays.
  • The study validates the use of inexpensive materials for advanced ultrasonic imaging.
