Abstract: A head-wearable device is configured to hold at least one ultrasound transducer such that it is properly positioned for brain stimulation. Such a head-wearable device can help to ensure that the transducer makes sufficient contact with the user's head to allow for efficient ultrasound coupling. Each device may also ensure that the ultrasound transducer maintains the same orientation and position relative to the head across successive donning and doffing of the device.

Abstract: A method for ultrasound power Doppler image reconstruction includes obtaining sparse sequences of compound frames of ultrasound data; inputting the sparse sequences into a convolutional neural network; and generating as output from the convolutional neural network a reconstructed time series of power Doppler images corresponding to the sparse sequences. The convolutional neural network is trained using a custom loss function to learn a reconstruction function using ground truth images from high-quality in vivo images.

Abstract: An ultrasound imaging system includes a transducer array with a plurality of transducer elements configured to repeatedly emit in a predetermined pattern, a first beamformer configured to beamform echo signals received by the transducer array to produce a low resolution line of data for each emission, and a first communication interface configured to wirelessly transmit the low resolution lines of data for each emission in series. The ultrasound imaging system further includes a second communication interface configured to for each emission in series wirelessly receive the transmitted low resolution lines of data, a second beamformer configured to beamform the received low resolution lines of data to produce high resolution ultrasound data, and a velocity processor configured to estimate vector velocity components from the high resolution ultrasound data in a lateral direction and an axial using an autocorrelation algorithm.
