An ultrasound patch includes one or more transmit and receive piezoelectric transducer elements. In some embodiments, the transducer elements are positioned on a ramp on a patient pad of the patch that is configured to fit within an anatomic space between the trachea and the sternocleidomastoid muscle to orient the transducer elements toward a carotid artery. In some embodiments, a flexible phased array transducer includes a number of pillar piezoelectric elements joined by a flexible adhesive with metal electrodes deposited thereon. The phased array transducer is mounted to a flexible circuit board that allows the transducer to bend and conform to a subject's anatomy.

A dual frequency transducer array includes one or more low frequency transducer arrays and a high frequency transducer array. Unfocused ultrasound such as plane waves are transmitted by the one or more low frequency transducer arrays in a number of different directions into an imaging region of the high frequency transducer array. High frequency echo signals produced by excited contrast agent in the imaging region are received by the high frequency transducer array to produce a contrast agent image. In another embodiment, the high frequency transducer produces unfocused ultrasound to excite the contrast agent in the imaging region and the low frequency transducer(s) receives low frequency echo signals from the excited contrast agent. A tissue image is created from echo signals received by the high or low frequency transducer. Echo data from the tissue image and the contrast agent image are combined to produce a combined tissue/contrast agent image.
