  • Patent number: 10664685
    Abstract: Methods, systems, and devices described herein enable single-image optical sectioning, even at depth within turbid media, such as human skin or other tissue. Embodiments can eliminate the need for multiple image samples or raster scans, making in-vivo or live biological imaging easier and faster than multi-image sectioning techniques. Better contrast and resolution than traditional three-phase structured illumination microscopy (SIM) is possible in turbid media. Embodiments enable imaging of cell nuclei. Resolution and contrast resulting from disclosed embodiments are less sensitive to motion of or within patients or other targets than confocal microscopy and three-phase SIM techniques. Three-dimensional images of target specimens can be provided based on a group of single-image optical sections. Real-time imaging can also be provided.

  • Patent number: 10643319
    Abstract: A method and apparatus is provided generate a display image that optimize a tradeoff between resolution and noise by using blending weights/ratio based on the content/context of the image. The blending weights control the relative weights when combining multiple computed tomography (CT) images having different degrees of smoothing/denoising to generate a display image having the optimal tradeoff lying within the continuum between/among the CT images. The blending weights are automated based on information indicating the content/context of the display image (e.g., the segmented tissue type, average attenuation, and the display setting such as window width and window level). Thus, indicia indicating content/context of the image determine the weighting coefficients, which are used in a weighted sum, e.g., to combine the plurality of images with different noise/smoothing parameters into a single blended image, which is displayed.

  • Patent number: 10643333
    Abstract: A local extension method for segmentation of anatomical treelike structures includes receiving an initial segmentation of 3D image data including an initial treelike structure. A target point in the 3D image data is defined, and a region of interest based on the target point is extracted to create a sub-image. Highly tubular voxels are detected in the sub-image, and a spillage-constrained region growing is performed using the highly tubular voxels as seed points. Connected components are extracted from the results of the region growing. The extracted components are pruned to discard components not likely to be connected to the initial treelike structure, keeping only candidate components likely to be a valid sub-tree of the initial treelike structure. The candidate components are connected to the initial treelike structure, thereby extending the initial segmentation in the region of interest.

  • Patent number: 10636142
    Abstract: For soft tissue deformation prediction, a biomechanical or other tissue-related physics model is used to find an instantaneous state of the soft tissue. A machine-learned artificial neural network is applied to predict the position of volumetric elements (e.g., mesh node) from the instantaneous state. Since the machine-learned artificial neural network may predict quickly (e.g., in a second or less), the soft tissue position at different times or a further time given the instantaneous state is provided in real-time without the minutes of physics model computation. For example, a real-time, biomechanical solver is provided, allowing interaction with the soft tissue model, while still getting accurate results. The accuracy allows for generating images of a soft tissue with greater accuracy and/or the benefit of user interaction in real-time.

    Abstract: An arrangement for light sheet microscopy including: a sample vessel, for receiving a medium containing sample, having a covering and being oriented with respect to a planar reference surface; illumination optics with an illumination objective for illuminating the sample with a light sheet; and detection optics with a detection objective. The optical axis of the illumination objective and the light sheet lies in a plane that forms a nonzero illumination angle with the normal of the reference surface. The optical axis of the detection objective forms a nonzero detection angle with the normal of the reference surface. A bulge is formed at the covering for receiving the sample. The bulge has inner and outer interfaces. The optical axes of the illumination objective and detection objective form a minimal angle with the normals of the interfaces at least in the region where the optical axes pass through the interfaces.

  • Patent number: 10620280
    Abstract: A method of data acquisition at a magnetic resonance imaging (MRI) system is provided. The system receives at least a portion of raw data for an image, and detects anomalies in the portion of raw data received. When anomalies are detected, the system can correct those anomalies dynamically, without waiting for a new scan to be ordered. The system can attempt to scan the offending portion of the raw data, either upon detection of the anomaly or at some point during the scan. The system can also correct anomalies using digital correction methods based on expected values. The anomalies can be detected based on variations from thresholds, masks and expected values all of which can be obtained using one of the ongoing scan, previously performed scans and apriori information relating to the type of scan being performed.

  • Patent number: 10621468
    Abstract: Techniques are disclosed for image feature representation. The techniques exhibit discriminative power that can be used in any number of classification tasks, and are particularly effective with respect to fine-grained image classification tasks. In an embodiment, a given image to be classified is divided into image patches. A vector is generated for each image patch. Each image patch vector is compared to the Gaussian mixture components (each mixture component is also a vector) of a Gaussian Mixture Model (GMM). Each such comparison generates a similarity score for each image patch vector. For each Gaussian mixture component, the image patch vectors associated with a similarity score that is too low are eliminated. The selectively pooled vectors from all the Gaussian mixture components are then concatenated to form the final image feature vector, which can be provided to a classifier so the given input image can be properly categorized.

  • Patent number: 10621704
    Abstract: The herein invention discloses and claims a quantitative image restoration in bright field (QRBF) method that faithfully recovers shape and enables quantify size of individual unstained samples. The QRBF method restores out-of-focus BF images of unstained samples by applying deconvolution, which enhances contrast and allows for quantitative analysis. To perform deconvolution our procedure uses a point spread function modeled from theory. Image deconvolution can be performed even from a single input image in two dimensions (2D-QRBF), and quantitative information such as size and shape of samples can be determined from restored 2D-QRBF images. Application of 2D-QRBF in a high-throughput screening process to assess shape changes in cells during hyperosmotic shock shows that the described digital restoration approach is suitable for quantitative analysis of unstained BF images in high-throughput image cytometry.
