Flexible Two-Dimensional Ultrasound Phased Array System
Summary
The USPTO granted patent US12588895B2 to inventors Kenneth Shepard, Jeffrey Ellosian, and Tiago Costa for a flexible two-dimensional ultrasound phased array system. The invention comprises a flexible substrate with integrated circuits that control ultrasound transducer excitation phases based on substrate shape. This patent covers medical ultrasound imaging applications including diagnostic and surgical guidance.
What changed
The USPTO issued Patent No. US12588895B2 on March 31, 2026, granting exclusive rights to a flexible ultrasound phased array apparatus. The system includes a flexible printed circuit board substrate, an array of bulk piezoelectric transducers, and ICs configured to independently control transmission magnitude and phase for focusing energy that compensates for device curvature. The patent contains 23 claims covering the integrated design and phase compensation methodology.
Patent holders and licensees should document this grant for intellectual property portfolios. Medical device manufacturers developing flexible ultrasound probes should review this patent for potential licensing requirements or design-around considerations. No immediate compliance actions are required as patent grants do not impose regulatory obligations on third parties.

Abstract
An exemplary ultrasound (US) apparatus, can include, for example, a flexible substrate, a plurality of ultrasound transducers coupled to the flexible substrate, and an integrated circuit(s) (IC(s)) mounted on the substrate to drive and control the transducer array, where the IC(s) can be configured to control an excitation phase of the ultrasound transducers based at least in part on a shape of the flexible substrate. The ultrasound transducers can be an array of bulk piezoelectric transducers. The substrate can be a flexible printed circuit board. The IC(s) can be configured to separately control (i) a transmission of ultrasound energy from each of the transducers, (ii) a magnitude, or a (iii) phase, where the IC(s) can be configured to use the phase to focus the transmitted energy compensating for a curvature of the ultrasound apparatus.
