    Abstract: A miniaturized device providing hyperspectral imaging in real-time includes a body, a camera within the body, a micro-LED array arranged around the camera within the body, and an imaging controller within the body and coupled to the camera and the micro-LED array. The micro-LED array includes micro-LEDs of varying spectral bands. A method for controlling an imaging device includes providing LED timing information and LED intensity information to a micro-LED array, providing camera timing information to a camera for capturing a plurality of images, and receiving the plurality of images from the camera. The timing information includes a timing signal to each micro-LED of the micro-LED array and each timing signal includes a pulse. An image of the plurality of images is captured for a time period associated with each timing signal.

  • Publication number: 20230125377
    Abstract: Systems and methods are provided for label-free, real-time hyperspectral imaging (HSI) endoscopy for molecular-guided surgery of cancers without the need for an exogenous contrast agent. One device is a high-speed image mapping spectrometer integrated with a white-light reflectance fiberoptic bronchoscope. The imaging system has a parallel acquisition instrument that captures a hyperspectral datacube that may be pre-processed and features extracted and a discriminative feature set is selected and used for the classification of cancer and benign tissue. An algorithm that enables fast and accurate tissue classification may also be applied that utilizes a supervised deep-learning-based framework that is trained with the clinically visible tumor and benign tissue during surgery and then applied to identify the residual tumor.

  • Patent number: 9142030
    Abstract: Systems, methods, and computer-readable storage media relate to segmenting an image series of at least one image of a region of interest of a subject. The methods, systems, and computer readable storage media can automatically segment interior and exterior boundaries relative to the region of interest (e.g., epicardial and endocardial boundaries with respect to a right ventricle) from an image series by combining sparse matrix transform, a training model, and a localized region based level set function.

  • Patent number: 8422757
    Abstract: A method is provided that comprises receiving a first digital radiography (DR) image of at least a portion of a body of a patient, receiving a second DR image of the at least a portion of a body of a patient, the first DR image being captured at a different energy level than the second DR image, and determining common control point locations for both the first and second DR images. The method further comprises generating an optimized DR image by moving portions of a selected one of the first and second DR images with its associated control points to locations that correspond to similar portions of the other of the first and second DR images, applying deformable transformation to one of the first and second DR images and performing a log subtraction on the first and second DR image to generate a dual-energy digital radiography (DEDR) image.
