摘要： Vertical packaging configurations for ultrasound chips are described. Vertical packaging may involve use of integrated interconnects other than wires for wire bonding. Examples of such integrated interconnects include edge-contact vias, through silicon vias and conductive pillars. Edge-contact vias are vias defined in a trench formed in the ultrasound chip. Multiple vias may be provided for each trench, thus increasing the density of vias. Such vias enable electric access to the ultrasound transducers. Through silicon vias are formed through the silicon handle and provide access from the bottom surface of the ultrasound chip. Conductive pillars, including copper pillars, are disposed around the perimeter of an ultrasound chip and provide access to the ultrasound transducers from the top surface of the chip. Use of these types of packaging techniques can enable a substantial reduction in the dimensions of an ultrasound device.

摘要： A method of forming an ultrasonic transducer device includes forming and patterning a film stack over a substrate, the film stack comprising a metal electrode layer and a chemical mechanical polishing (CMP) stop layer formed over the metal electrode layer; forming an insulation layer over the patterned film stack; planarizing the insulation layer to the CMP stop layer; measuring a remaining thickness of the CMP stop layer; and forming a membrane support layer over the patterned film stack, wherein the membrane support layer is formed at thickness dependent upon the measured remaining thickness of the CMP stop layer, such that a combined thickness of the CMP stop layer and the membrane support layer corresponds to a desired transducer cavity depth.

摘要： Aspects of the technology described herein relate to ultrasound imaging of lungs. An ultrasound device may be configured with a set of parameter values associated with a shallow lung imaging mode. A selection of a change in imaging depth may be received. If the selected imaging depth is greater than or equal to a threshold imaging depth, the ultrasound device may be configured with a set of parameter values associated with a deep lung imaging mode. The set of parameter values associated with the shallow lung imaging mode may be optimized for imaging lung sliding and the set of parameter values associated with the deep lung imaging mode may be optimized for imaging A lines and B lines.

摘要： Aspects of the technology described herein relate to guiding collection of ultrasound data collection using motion and/or orientation data. Motion and/or orientation data may be received from an ultrasound imaging device, where the motion and/or orientation data provides an indication of the motion and/or orientation of the ultrasound imaging device. Ultrasound data collected by the ultrasound imaging device may also be received. An instruction for moving the ultrasound imaging device based on the motion and/or orientation data and the ultrasound data may be provided. Ultrasound data and motion and/or orientation data may indicate a velocity of the ultrasound imaging device that exceeds a threshold velocity and an instruction for slowing the velocity of the ultrasound imaging device may be provided.

摘要： Aspects of the technology described herein relate to delivery of pressure based on ultrasound data. Certain aspects relate to receiving ultrasound data collected from a subject by a wearable ultrasound device, determining that the ultrasound data indicates apnea (e.g., absence of lung sliding or movement of internal abdominal organs), and based on determining that the first ultrasound data indicates apnea, increase pressure being delivered to the subject. To increase the pressure, a positive airway pressure device may increase the pressure it generates, an adapter may route power to the positive airway pressure device, or a valve may permit air to flow from the positive airway pressure device to the subject. Increasing pressure may be triggered by an activation signal transmitted by the wearable ultrasound device or a processing device. The wearable ultrasound device may be a patch configured to couple to the subject's skin.

摘要： An ultrasonic transducer includes a membrane, a bottom electrode, and a plurality of cavities disposed between the membrane and the bottom electrode, each of the plurality of cavities corresponding to an individual transducer cell. Portions of the bottom electrode corresponding to each individual transducer cell are electrically isolated from one another. Each portion of the bottom electrode corresponds to each individual transducer that cell further includes a first bottom electrode portion and a second bottom electrode portion, the first and second bottom electrode portions electrically isolated from one another.
