Abstract: A membrane hydrophone for analyzing high frequency ultrasound transducers has a piezoelectric membrane with electrode patterns created on the surface of the membrane. In one embodiment, the electrode patterns are doubled on each side of the membrane except for an active area of the hydrophone. In one embodiment, the electrodes are formed by removing a conductive coating on the membrane with laser pulses. The laser is set to remove the conductive coating from the piezoelectric membrane from the same side of the membrane in order to accurately align the electrodes in the active area. In one embodiment, the active area of the hydrophone has an area in a range of 900 - 10,000 square microns.

Abstract: A high frequency ultrasound array having a number of transducer elements that are formed in sheet of piezoelectric material. A frame having a coefficient of thermal expansion similar to that of the piezoelectric material surrounds the piezoelectric material and is separated from the piezoelectric material by an epoxy material. Kerf cuts that define the individual elements in the sheet of piezoelectric material extend across a full width of the sheet. In some embodiments, sub-dice kerf cuts that divide a single transducer element into two or more sub-elements also extend all the way across the width of the sheet. A lens positioned in front of the transducer elements can have a radius machined therein to focus ultrasound signals. The frame, transducer elements and lens are bent or curved with the desired radius to focus ultrasound signals.

Abstract: A dual frequency ultrasound transducer includes a high frequency (HF) transducer and a low frequency (LF) transducer that is positioned behind the high frequency transducer. An intermediate layer is positioned between the low frequency transducer and the high frequency transducer to absorb high frequency ultrasound signals. An alignment feature on the low frequency transducer is positioned with respect to a fiducial that is marked at a known position with respect to high frequency transducer elements of the HF transducer to align low frequency transducer elements of the LF transducer with the HF transducer elements.

Abstract: A high frequency ultrasound array having a number of transducer elements that are formed in sheet of piezoelectric material. A frame having a coefficient of thermal expansion that is similar to that of the piezoelectric material surrounds the piezoelectric material and is separated from the piezoelectric material by a filling material.

Abstract: Disclosed is a medical device that includes a phased array ultrasound transducer. The transducer includes a number of transducer elements that are electrically coupled to corresponding electrical conductors. In one embodiment, the conductors are included in a flex circuit and engage corresponding transducer elements though a conductive surface formed on outwardly extending ribs of a frame that holds the ultrasound array. In one embodiment, the phased array is forward facing in the medical device and has an element pitch of 0.75 lambda or less and more preferably 0.6 lambda or less. In one embodiment, the transducer is rotatable over an angle of +/- 90 degrees to provide a 360 degree view of tissue surrounding the distal end of the device.
