Abstract: A three dimensional ultrasound scanning system includes devices to capture an acquisition state for a scan including quantitative data about the conditions under which the scan was obtained. The conditions may include pose and contact force of an ultrasound probe in relation to a target. This data may be used to obtain a three dimensional reconstructed volume of a target.

Abstract: The systems and methods of the present disclosure are directed to ultrasound-based concentration measurement techniques in which both scatterer count and image volume are measured concurrently to provide absolute concentration measurements. In particular, through the techniques of the present disclosure, the effective thickness of an ultrasound beam can be determined based on the spreading of individual scatterers within ultrasound images. Based on the effective thickness of the ultrasound beam, the volume of the image and, thus, the concentration of particles in the image can be determined directly, without the need for estimation, approximation, or use of a reference sample.

Abstract: An ultrasound scanning system includes a graphical user interface that provides visually intuitive feedback to a user to assist the user in properly aligning an ultrasound scanner to a desired acquisition state. In addition to providing pose information, the feedback may direct the user as to a target contact force applied by the ultrasound scanner to a surface undergoing a scan.

Abstract: A photonic aerosol particle sensor includes a microfluidic sensor chamber in which is disposed a plurality of photonic waveguide resonators each having a photonic waveguide on an underlying substrate, along a separate waveguide resonator path with a lateral width different than that of other photonic waveguide resonators. All waveguides in the plurality have a common vertical thickness of a common waveguide material having a refractive index that is larger than that of the underlying substrate material. An optical input connection couples light into the waveguide resonators. An aerosol particle input fluidically connected to the microfluidic chamber fluidically conveys aerosol particles to the chamber, and an aerosol particle output fluidically connected to the microfluidic chamber fluidically conveys aerosol particles out of the chamber. At least one optical output connection accepts light out of the plurality of photonic waveguide resonators to provide a signal indicative of at least one aerosol particle characteristic.

Abstract: Systems and methods are provided for imaging of soft and hard tissues with ultrasound. Such systems and methods can provide for non-contact and quantitative ultrasound images of bone and soft tissue. A method for imaging a biological body segment of soft and hard tissues includes setting geometry and material properties according to a model of the biological body segment to thereby generate a simulated time series data set. The method further includes collecting reflective and transmissive time series data of the biological body segment to thereby form an experimental time series data set and minimizing a difference between the simulated time series data set and the experimental time series data set, thereby imaging the biological body segment. Regularizing travel-time and/or using full waveform tomographic techniques with level set methods enable recovery of cortical bone geometry.

Abstract: A mechanical vibration source for a shear wave elastography system has a contact surface shaped to provide a point source of mechanical energy when striking a target surface of a medium. This point source usefully mitigates high frequency components and other artifacts in an induced shear wave. Other techniques may be used in combination with this mechanical energy source to improve shear wave elastography and facilitate miniaturization for deployment, e.g., within a handheld imaging device.

Abstract: A force-sensing ultrasound imaging device uses multiple force sensors to capture the spatial distribution of a contact force between the imaging device and a target surface. In another aspect, the device may provide an external force stimulus in order to facilitate synchronization of different hardware systems that independently acquire force sensor data and ultrasound transducer data.

Abstract: Described embodiments provide a method of generating an image of a region of interest of a target object. A plurality of concentric circular scan trajectories are determined to sample the region of interest. Each of the concentric circular scan trajectories have a radius incremented from an innermost concentric circular scan trajectory having a minimum radius to an outermost concentric circular scan trajectory having a maximum radius. A number of samples are determined for each of the concentric circular scan trajectories. A location of each sample is determined for each of the concentric circular scan trajectories. The locations of each sample are substantially uniformly distributed in a Cartesian coordinate system of the target object. The target object is iteratively rotated along each of the concentric circular scan trajectories and images are captured at the determined sample locations to generate a reconstructed image from the captured images.
