US Patent 10149660 Ultrasound endoscope and methods of manufacture thereof

To address limitations of conventional transducers, a phased array transducer is provided with a form factor suitable o for packaging into, e.g., an endoscope. A method of manufacture of small packaging transducers is also provided, whereby the overall package size is reduced by electrically connecting signal wires to array electrodes at an angle approximately normal to the array surface, thus largely eliminating the bend radius requirements of conventional printed circuit boards or flex circuits.
