Applications of CMUT Technology in Medical Diagnostics: From Photoacoustic to Ultrasonic Imaging
Srushti Kulkarni, Karan Dhingra, Saloni Verma
Abstract: Transducers have been used for a variety of operations, largely medical imaging for decades using piezoelectric material as conventional techniques. While commercial piezoelectric transducers rely on response to mechanical stress, measurement in the form of change in capacitance is the unique proposition offered by capacitive micromachined ultrasonic transducers (CMUT). CMUTs offer multiplexing capabilities, large scale production, low frequency operation, and integration options making them a go - to for industry leaders towards medical imaging fabrication for applications such as ultrasonic imaging. Polymer substrate based CMUTs have shown to provide versatility in photoacoustic tomography while dual - frequency and multiband CMUTs have provided capabilities of dual - mode imaging on a single array. Such advancements have paved the path into high intensity ultrasound and even ultrasound mediated drug delivery. This review provides an overview of the latest developments in CMUT technology, the principle of operation, advancements with recent findings, and prospects of integrating with artificial intelligence (AI) to maximize efficiency.
