A 360° fully functional endoscopic ultrasound radial array has been fabricated and evaluated. Transducer was specially designed to match the endoscope structure, which has a 10.5mm outer diameter, a 7.5mm inner diameter and a system connecting cable measuring 3.5m. Considering the size limitation in endoscopic application and transducer fabrication capability, two transducer designs with 192 and 252...
In this paper, we designed and simulated a multilayer planar resonator with target frequency of 2.5 MHz which is created over a row/column-addressed 2D CMUT array. We have shown through finite element modeling and simulations that a particle can be trapped and manipulated both in lateral and axial directions inside the fluid channel by activating CMUT elements; And calculated acoustic radiation force...
