  • Patent number: 10309936
    Abstract: A system is provided for component separation. In an embodiment, a light source or other source of electromagnetic energy delivers energy to a volume of tissue. A transducer array or other sensor receives a resulting acoustic signal, and a processing subsystem processes the acoustic signal to separate a direct acoustic return component from a secondary acoustic return component of the acoustic signal. An output and/or storage device presents and/or stores information about the direct acoustic return component, the secondary acoustic return component, or both. Other embodiments include a coded probe, a probe having an isolator that produces a wavefront, a sensor for measuring intensity of an acoustic wave produced by absorbed photons, and a system that receives acoustic signals from surface targets to determine an optical parameter of the volume.

  • Patent number: 10285761
    Abstract: Systems and methods are provided for identifying a suitable surgical location and/or trajectory for proceeding with a surgical procedure based on local polarization-sensitive optical coherence tomography imaging (PS-OCT). PS-OCT images are obtained of a tissue region and are processed to provide a spatial map of anisotropic structure within the tissue region. The anisotropic structure is processed to determine one or more suitable surgical locations and/or trajectories for avoiding or reducing damage to local anisotropic tissue structure identified within the tissue region. The spatial map of the anisotropic structure is registered with pre-operative volumetric image data identifying anisotropic tissue structure within a second tissue region that is larger than the tissue region imaged by PS-OCT.

  • Patent number: 10278587
    Abstract: Eyelid illumination systems and methods for imaging meibomian glands for meibomian gland analysis are disclosed. In one embodiment, a patient's eyelid is IR trans-illuminated with an infrared (IR) light. A trans-illumination image of the patient's eyelid is captured showing meibomian glands in dark outlined areas, whereas non-gland material is shown in light areas. This provides a high contrast image of the meibomian glands that is X-ray like. The lid trans-illumination image of the meibomian glands can be analyzed to determine to diagnose the meibomian glands in the patient's eyelid. The eyelid may be trans-illuminated by a lid-flipping device configured to grasp and flip the eyelid for imaging the interior surface of the eyelid. Also, an IR surface meibography image of the meibomian glands may also be captured and combined with the trans-illumination image of the meibomian glands to provide a higher contrast image of the meibomian glands.

  • Patent number: 10258314
    Abstract: Systems and methods for ultrasound imaging capable of achieving spatial resolutions that can resolve objects smaller than 300 ?m are described. Ultrasound is transmitted to and steered over a volume-of-interest that contains a microbubble contrast agent to individually excite microbubbles. Signal data is acquired in response to the transmitted ultrasound, and a plurality of images are reconstructed by beamforming the acquired signal data. The spatial resolution of the beamformed images can be further increased using techniques that determine the position of the microbubble within each image to a greater level of accuracy than the point spread function (“PSF”) of the ultrasound system. The images can also be combined to produce a single high resolution image of the volume-of-interest using, for instance, a maximum pixel projection technique.

  • Patent number: 10226236
    Abstract: Adjustment of operation of an ultrasound imaging system may be based at least in part on one or more characteristics represented in ultrasound return signals from two or more sample volumes. Adjustment may include adjusting a principal sample volume location or selecting a new principal sample volume. For example, a location of a principal sample volume may be adjusted or new principal sample volume selected so as to remain focused on an identified region of interest or to maintain the principal sample volume relative to some structure or reference. The principal sample volume may be maintained in the center or along a centerline of an artery or other structure, as the transducer array is moved along the artery or structure.
