  • Patent number: 11808703
    Abstract: The disclosed embodiments provide a system that images a tissue sample. During operation, the system receives the tissue sample, which has been stained using absorbing and fluorescently emitting stains. Next, the system illuminates the tissue sample with excitation light having a wavelength or wavelengths in a range that covers a portion of an absorption spectrum for both fluorescently emitting and absorbing stains, whereby the excitation light interacts with stained tissue located inside the tissue sample to both limit penetration depth and generate emitted dye fluorescence and tissue autofluorescence that provides a backlight, which is absorbed by features in stained tissue located on or near the surface of the tissue sample. Next, the system uses an imaging device to capture an image of emitted fluorescence that emanates from the surface of the tissue sample.

  • Patent number: 11806189
    Abstract: For three-dimensional segmentation from two-dimensional intracardiac echocardiography imaging, the three-dimension segmentation is output by a machine-learnt multi-task generator. Rather than the brute force approach of training the generator from 2D ICE images to output a 2D segmentation, the generator is trained from 3D information, such as a sparse ICE volume assembled from the 2D ICE images. Where sufficient ground truth data is not available, computed tomography or magnetic resonance data may be used as the ground truth for the sample sparse ICE volumes. The generator is trained to output both the 3D segmentation and a complete volume (i.e., more voxels represented than in the sparse ICE volume). The 3D segmentation may be further used to project to 2D as an input with an ICE image to another network trained to output a 2D segmentation for the ICE image. Display of the 3D segmentation and/or 2D segmentation may guide ablation of tissue in the patient.

  • Patent number: 11806146
    Abstract: The methods and systems described herein enable the accurate diagnosis of novel biotypes of depression that transcend current diagnostic boundaries and may be useful for identifying individuals who are most likely to benefit from antidepressant treatment. Functional magnetic resonance imaging is used to characterize the architecture of functional connectivity across the brain to show that patients with depression can be subdivided into four neurophysiological biotypes based solely on unique patterns of abnormal connectivity in resting state brain networks. Clustering subjects on this basis reduces diagnostic heterogeneity, enabling the development of depression biotype classifiers for diagnosing biotypes of depresion in individual patients, These biotypes also predict differing responses to antidepressant treatment, and abnormal connectivity patterns can be used to track changes in depression severity over time.

  • Patent number: 11786193
    Abstract: The present disclosure describes methods and apparatuses for reducing metal artifacts in cone beam computed tomography (CBCT) reconstructions. The methods use multiple imaging modalities to identify and locate metal present in a region of dental patients mouth and to generate a reconstructed 3-D volume image of the region with reduced metal artifacts using data obtained by the multiple modalities. According to example embodiments, the methods include creating a metal map using data from a first imaging modality and an initial 3-D reconstruction from data obtained from a second imaging modality including CBCT imaging. The metal map is registered to the initial 3-D reconstruction with a reconstructed metal map and projection metal maps being subsequently produced and applied to projections from the CBCT imaging to generate interpolated projections.

  • Patent number: 11788888
    Abstract: A method and device for restoring and reconstructing a light source spectrum based on a hyperspectral image are provided. A hyperspectral image is processed to obtain a first maximum spectrum. The first maximum spectrum is matched with a light source spectral basis vector set in a light source spectrum dictionary, and a linear decomposition is performed to obtain a dictionary set. The maximum value of each waveband is obtained and iterative approximation is performed. Therefore, it can quickly restore the spectrum of the light source of the shooting environment from a single hyperspectral image using a relatively simple calculation process, and can still achieve a good restoration effect for monochromatic image scenes or image scenes with few colors, even close to the real light source spectrum. After the light source spectrum is obtained, this information can be further utilized for different kinds of applications.

  • Patent number: 11779242
    Abstract: Systems and methods use a three-dimensional snapshot of an infant, child, adolescent, or adult where the subject may have bent legs and an unaligned head position, to provide an estimate of human length. The system identifies anatomical features from the digital information and generates a virtual skeleton. The cumulative distances between pseudo-joints of the virtual skeleton provide an estimate of human length. Comparing length estimates from multiple three-dimensional snapshots of the same individual acquired over time provide an indication of growth of the infant, child, or adolescent. Daily estimates of length can detect growth faltering sooner than less frequent estimates of length, which can lead to timely intervention.
