| contents | <p dir="auto">A detailed blueprint for an acoustic metamaterial platform designed to advance ultrasound medical imaging by focusing 1 to 5 MHz sound waves with sub-millimeter precision, ideal for detecting features like tumors or microcalcifications. Originally developed for an acoustic analog black hole study, this platform uses a 3D-printed PLA gyroid lattice with 0.5 to 1 mm cells, a 12 to 15% per mm porosity gradient, and 0.15 mm walls to control sound waves in a CO2-helium medium (sound speed approximately 270 m/s). A 0.5 mm cell honeycomb straightener maintains flow stability (velocity fluctuations approximately 1.5 m/s), and a signal processing pipeline with Morlet wavelets (center frequency 3 MHz) and Bayesian filtering achieves a signal-to-noise ratio of 62 to 64 dB for faint echoes (approximately 10^-15 W/m^2). Operating at room temperature (298 K), this setup is practical for portable diagnostic devices. As an independent researcher without lab facilities, I offer this design to encourage experimentalists to build it and share data on echo detection, focal resolution, and wave profiles, contributing to ultrasound imaging research and my studies on wave propagation</p> |
