Laser Micromachined Flexible Ultrasound Line Array and Subplanar Multimodal Imaging Applications

Flexible ultrasound array with phased configurations have individually controllable element emission and reception acoustic properties, however conventional processes design are too complex. It is necessary to explore rapid creation methods potential applications for flexible arrays. In this paper, we provide a method fabrication of transducers based on laser micromachining verify the performance line by multi-mode positioning imaging under curved surfaces. The proposed single-layered double-sided conductive stretchable electrode configuration eliminated blockage waves,and ’island bridge’ structures compatible flexibility excitation row addressing.The mechanical, electrical interconnections verified.Based Verasonics system, ultrasonic scans multiple steel column targets in modalities surfaces localization.The results show that can obtain clear visual localization images A-scan, B-scan E-scan poses.In addition, artifacts be effectively suppressed adjusting depth focus optimizing sparse structure. verified has field imaging.
