Latest Patents

One of Dahl's latest patents is a method for estimating the local speed of sound in medical ultrasound. This innovative technique involves inducing ultrasound waves in a subject by focusing an ultrasound beam. It utilizes an ultrasound Tx transducer to propagate waves from a focal point to the surface. The method measures the time of arrival of the waves using at least three single Rx transducer surface elements. The signal traces recorded on individual Rx transducers are evenly sampled in time. The average speed of sound is calculated as an arithmetic mean of local sound-speed values sampled along a wave path. Each Rx transducer outputs a separate arrival time of the waves, allowing for the computation of a local speed of sound (c) using a computer that receives these arrival times. This method can be used to differentiate human diseases based on ultrasound measurements.

Another notable patent by Dahl focuses on ultrasound speckle reduction and image reconstruction using deep learning techniques. In this innovation, ultrasound B-mode images are reconstructed directly from transducer channel signals using a convolutional neural network (CNN). The CNN is trained with a dataset that includes simulated transducer array channel signals containing simulated speckle, with corresponding simulated speckle-free B-mode ground truth images as outputs. After training, real-time RF signals taken directly from ultrasound transducer array elements are input to the CNN, which processes them to generate an estimated real-time B-mode image with reduced speckle.
