摘要： Micromachined ultrasonic transducers having pressure ports are described. The micromachined ultrasonic transducers may comprise flexible membranes configured to vibrate over a cavity. The cavity may be sealed, in some instances by the membrane itself. A pressure port may provide access to the cavity, and thus control of the cavity pressure. In some embodiments, an ultrasound device including an array of micromachined ultrasonic transducers is provided, with pressure ports for at least some of the ultrasonic transducers. The pressure ports may be used to control pressure across the array.

摘要： Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.

摘要： An ultrasound system may include an ultrasound device that includes a first wired communication module and a first wireless communication module. The ultrasound system may further include a processing device that includes a second wired communication module and a second wireless communication module. The processing device may pair with the ultrasound device over a wireless connection using the first wireless communication module and the second wireless communication module. The processing device may further indicate a wireless connection on a display screen of the processing device. The processing device may further conduct an ultrasound imaging session over the wireless connection. The processing device may further determine that a cable has been connected between the ultrasound device and the processing device. The processing device may further terminate the wireless connection with the ultrasound device.

摘要： Aspects of the technology described herein relate to techniques for guiding an operator to use an ultrasound device. Thereby, operators with little or no experience operating ultrasound devices may capture medically relevant ultrasound images and/or interpret the contents of the obtained ultrasound images. For example, some of the techniques disclosed herein may be used to identify a particular anatomical view of a subject to image with an ultrasound device, guide an operator of the ultrasound device to capture an ultrasound image of the subject that contains the particular anatomical view, and/or analyze the captured ultrasound image to identify medical information about the subject.

摘要： Aspects of the technology described herein relate to techniques for calculating, during imaging, a quality of a sequence of images collected during the imaging. Calculating the quality of the sequence of images may include calculating a probability that a medical professional would use a given image for clinical evaluation and a confidence that an automated analysis segmentation performed on the given image is correct. Techniques described herein also include receiving a trigger to perform an automatic measurement on a sequence of images, calculating a quality of the sequence of images, determining whether the quality of the sequence of images exceeds a threshold quality, and performing the automatic measurement on the sequence of images based on determining that the quality of the sequence of images exceeds the threshold quality.

摘要： An ultrasound transducer device includes an electrode, a membrane, and vias. The membrane is separated from the electrode by a cavity between the membrane and the electrode. The vias electrically connect the electrode to a substrate disposed on an opposite side of the electrode from a side facing the membrane. The vias are disposed in the ultrasound transducer device such that greater than 50% of the vias overlap with the cavity in a plan view.
