Abstract: The present embodiments relate generally to ultrasound imaging systems and methods that provide a user interface on the touchscreen display. The user interface includes an ultrasound image feed and a single control for modifying imaging depth of the ultrasound image feed. When input via the single control is received to modify the imaging depth, the system: adjusts frequency of ultrasound signals being used to acquire the ultrasound image feed; adjusts a beamformer parameter of the ultrasound signals being used to acquire the ultrasound image feed; receives first image data of the ultrasound image feed based on the adjusted frequency and the adjusted beamformer parameter; based on the first image data, adjusts Time Gain Compensation (TGC) of the ultrasound image feed; and receives second image data of the ultrasound image feed based on the adjusted frequency, beamformer parameter and TGC. Display of the second image data on the touchscreen display is then optimized without receipt of additional user input.

Abstract: A solid-state spin sensor system for precisely measuring magnetic fields with a compliantly coupled sensor head exhibiting translational and rotational compliance is disclosed. The sensor includes a color center ensemble in a solid-state substrate for detecting magnetic fields with high spatial resolution. An optical microscope, in conjunction with an optical driving system, facilitates viewing and spin polarization of the color center ensemble. A magnetic field generator ensures biasing of the ensemble for better sensitivity, and a microwave driving system induces spin transitions within the ensemble. Actuation is controlled by a system responsive to force data or image data for precise positioning of the color center ensemble focally and in contact with a sample. The system generates a spatially resolved map of a magnetic field through analysis of fluorescence data.
