Abstract: An ultrasound imaging system for needle insertion guidance uses a curved array transducer to scan an image field with unsteered beams as a needle is inserted into the image field. Due to differences in the angle of incidence between the radially directed beams and the needle, echoes will return most strongly from only a section of the needle. This section is identified in an image, and the angle of incidence producing the strongest returns is identified. Beams with this optimal angle of incidence are then steered in parallel from the curved array transducer to produce the best needle image. The steep steering angles of some of the steered beams can give rise to side lobe clutter artifacts, which can be identified and removed from the image data using dual apodization processing of the image data.

Abstract: Techniques for monitoring devices to use ultrasonic signals to detect and track the locations of moving objects in an environment. To determine distance information, the monitoring devices emit a frequency-modulated continuous wave (FMCW) signal at an ultrasound frequency range. Reflections of the FMCW ultrasonic signal are used to generate time-of-arrival (TOA) profiles that indicate distances between the monitoring device and objects in the environment. The reflections can be processed to suppress undesirable interferences, such as reflections off non-mobile objects in the environment (e.g., walls, furniture, etc.), vibrations off the floorings or the ceilings, etc. After processing the reflections, a heatmap can be used to plot the intensity of the reflections for the different TOAs of the reflections, and depict the movement of the user over time. Finally, a Kalman filter is used to smooth the peaks in the intensity values on the plot, and determine the trajectory of the human.
