    Abstract: The method of detecting bone fractures using backscattered light makes use of backscattered near infrared (NIR) light to determine if a body part of a patient is healthy, has a bone fracture, or has an edema. An incident beam of near infrared light is generated by a light source, and has both an incident amplitude and an incident phase. The incident beam of NIR light is directed toward the patient's body part, and a backscattered beam of NIR light is received from the body part. The backscattered beam of NIR light has a backscattered amplitude and a backscattered phase. The determination of whether the body part is healthy, has a bone fracture or has an edema is made based on the level of absorption of the incident beam of NIR light and/or based on the amount of scattering, based on the phase difference, of the incident beam of NIR light.

    Abstract: The disclosed embodiments relate to a system that displays an image of the characteristics of the biological tissue. During operation, the system enables a user to illuminate a measurement location in an area of interest on the biological tissue by manipulating a point measurement probe, wherein the point measurement probe delivers both an excitation beam and an overlapping aiming beam that is visible to a camera. Next, the system obtains fluorescence information from a fluorescence signal emitted from the measurement location in response to the excitation beam. The system then captures an image of the area of interest using the camera and identifies a portion of the image that corresponds to the measurement location by identifying a location illuminated by the aiming beam. Finally, the system generates an overlay image by overlaying the fluorescence information onto the portion of the image that corresponds to the measurement location, and then displays the overlay image to a user.

  • Patent number: 10342432
    Abstract: An apparatus for turbid sample measurement comprising a plurality of light sources for illuminating a turbid sample target area with non-spatial structured light, a projection system for illuminating the turbid sample target area with spatial structured light, a sensor for collecting light from the turbid sample target area, and a processor to analyze the data captured by the sensor to yield scattering and absorption coefficients of the turbid sample. A method comprises illuminating the sample with spatial structured light, collecting light reflected from the sample at a number of wavelengths, illuminating the sample with non-spatial structured light, collecting light reflected from the sample at a number of wavelengths, and combining the measurements of the collected light to obtain the optical properties of the sample and/or the concentration of absorbing or fluorescent molecules. The wavelengths of the spatial and non-spatial light sources are preferably different.

  • Patent number: 10327951
    Abstract: Laser assisted cataract surgery methods and devices utilize one or more treatment laser beams to create a shaped opening in the anterior lens capsule of the eye when performing a capsulorrhexis procedure. A light absorbing agent may be applied to the anterior lens capsule to facilitate laser thermal separation of tissue along a treatment beam path on the lens capsule. Relative or absolute reflectance from the eye, and optionally from a surgical contact lens, may be measured to confirm and optionally quantify the presence of the light absorbing agent, before the treatment beam is applied.

  • Patent number: 10264974
    Abstract: Disclosed are methods for imaging lumen-forming structures such as blood vessels using near-infrared fluorescence in the NIR-II region of 1000-1700 nm. The fluorescence is created by excitation of solubilized nano-structures that are delivered to the structures, such as carbon nanotubes, quantum dots or organic molecular fluorophores attached to hydrophilic polymers. These nanostructures fluoresce in the NIR-II region when illuminated through the skin and tissues. Fine anatomical vessel resolution down to ?30 ?m and high temporal resolution up to 5-10 frames per second is obtained for small-vessel imaging with up to 1 cm penetration depth in mouse hind limb, which compares favorably to tomographic imaging modalities such as CT and MRI with much higher spatial and temporal resolution, and compares favorably to scanning microscopic imaging techniques with much deeper penetration.
