  • Patent number: 10653346
    Abstract: A low cost portable high speed quantitative system for diffuse optical spectroscopic imaging of human tissue. The hybrid system (CWFD) can measure absolute optical properties from 660 nm to 980 nm and recover all tissue chromophore concentrations. The standalone FD module can be utilized to measure scattering at every measurement and recover deoxygenated and oxygenated hemoglobin concentrations. The CW module can operate concurrently with the FD module to also measure water and lipid. The high temporal resolution and large signal-to-noise ratio of the CWFD system may be used to explore tissue oximetry, vascular occlusion, and paced breathing models to measure and analyze tissue hemodynamics response to changes in blood flow. Continuous monitoring of vasculature response to various modified blood perfusion conditions can provide information about local tissue metabolism and physiological state (dysfunction).

  • Patent number: 10606062
    Abstract: Medical imaging camera head devices and methods are provided using light captured by an endoscope system or other medical scope or borescope. Afocal light from the scope is manipulated and split. The resulting first and second beams are passed through focusing optics to a single sensor. To take better advantage of the available number image sensor pixels, the beam may pass through lens elements (or prisms) to generate an anamorphic aspect ratio prior to being split, increasing the resolution of the image in one dimension. The afocal anamorphic beam is then split, and both images are focused on the image sensor. The anamorphism is compensated for in image processing, permitting higher resolution in one dimension along the image sensor. The manipulation of the beams prior to being split (and in some cases after or while being split) can take several forms, each offering distinct advantages over existing systems.

  • Patent number: 10417737
    Abstract: A medical registration training component executing within a medical registration system performs a training medical registration operation on a pair of medical studies. Responsive to the medical registration training system determining that the training medical registration operation succeeds, the medical registration training system records a medical registration instance for the pair of medical studies in a medical registration history and marks the medical registration instance as a positive instance in the medical registration history. Responsive to the medical registration training system determining that the training medical registration operation requires correction, the medical registration training system records a medical registration instance for the pair of medical studies in the medical registration history and marks the medical registration instance as a negative instance in the medical registration history.

  • Patent number: 10408743
    Abstract: A method of evaluating formation of fouling material in a petroleum feed involves illuminating a sample with cross-polarized light while subjecting the sample to temperature and pressure conditions relevant to an industrial process to induce chemical and/or physical changes; collecting images of the treated sample; and analyzing the images to evaluate fouling formation based on heterogeneity of the images in terms of brightness and/or color, where an increase in heterogeneity is indicative of initiation of fouling formation. The method is conducted using a cross-polarized microscopy system including a hot stage reactor assembly capable of withstanding operation within a temperature between about 20° C. to 450° C. or higher, and a pressure between about 0.1 MPa to 16 MPa or higher.

  • Patent number: 10390738
    Abstract: Various patient monitoring systems can include a sensor configured to collect three dimensional information. The systems can identify a location of a patient support surface based on the three dimensional information. The systems can set a two dimensional planar threshold based on the patient support surface. The systems can identify a patient location above the patient support surface based on the three dimensional information and compare the patient location to the two dimensional planar threshold. Exceeding the threshold can be indicative of a high risk of a patient fall. An alert can be generated based on the threshold being exceeded. The systems can repeat the identification of the patient support surface location and the setting of the threshold to account for changes in the patient area.

  • Patent number: 10386301
    Abstract: Methods and devices are disclosed for the imaging of a biological sample with a top-down camera and a side-view camera. A biological sample is held on an imaging stage that is capable of rotation in two orthogonal axes. The top-down and side-view cameras can record a series of images of the sample using multiple imaging modalities at different rotational positions of the imaging stage. The top-down camera can be translated along its optical axis to affect the camera zoom and influence the resolution and field of view of the recorded images. Fluorescence excitation light sources can be positioned proximate to each of the top-down and side-view cameras to provide substantially uniform illumination of the sample for imaging with each camera.

  • Patent number: 10368752
    Abstract: Disclosed herein are devices and methods for modifying a conventional imager to have functional features similar to that of a lock-in camera. Optical mask devices are configured to be coupled to conventional imager sensors and the configuration of the mask devices can be adjusted to acquire image data in rapid succession. One variation of an optical mask device comprises a substrate comprising a pattern of light-blocking and light-transmitting regions and an attachment structure for coupling the optical mask device to the imager. The substrate is configured to adjust the position of the light-blocking regions and light-transmitting regions relative to the light-sensing region of the imager based on a set of one or more predetermined substrate configurations. In some variations, the mask device and/or the imager sensor may be mechanically moved relative to each other based on the set of one or more predetermined substrate configurations.
