    Abstract: With regard to a setting reference for X-ray irradiation range and image generation range, which differs by hospital or technician, a structure to automatically set a desired X-ray irradiation range and an image generation range infallibly, is provided. In an X-ray CT apparatus, a scan range automatic setting unit extracts an inspection target as an arbitrary body part designated by an operator before inspection from a positioning image, and generates an extraction region range including it. The operator sets an arbitrary margin value by line operation or numerical input using a GUI with respect to the extraction region range (S104). The scan range automatic setting unit generates and stores a range setting pattern in which the inspection target and the margin value are made to correspond to each other (S105), and links the range setting pattern to an inspection protocol (S106).

    Abstract: A method includes receiving an image from a mammogram, removing noise from the image, computing a point of interest on the de-noised image, creating a mesoscale region of interest on the de-noised image, computing a connectivity for the mesoscale region of interest, identifying a connected component using the computed connectivity, where the connected component represents a branch of a global curvilinear structure, selecting a set of branches based on a physical property for each branch of the global curvilinear structure, pruning each branch based on an error-tolerant, adaptive polynomial fit, identifying remaining regions of interest in each pruned branch, and growing a chain formed by remaining points of interest included in the remaining regions of interest, where the chain represents a macroscopic, global curvilinear calcified arterial structure. The quantitation of the calcified arterial structures may be used as a biomarker for risk stratification of heart disease.

  • Patent number: 10957045
    Abstract: Optimizations are provided for segmenting tissue objects included in an ultrasound image. Initially, raw pixel data is received. Here, each pixel corresponds to ultrasound information. This raw pixel data is processed through a first fully convolutional network to generate a first segmentation label map. This first map includes a first set of objects that have been segmented into a coarse segmentation class. Then, this first map is processed through a second fully convolutional network to generate a second segmentation label map. This second map is processed using the raw pixel data as a base reference. Further, this second map includes a second set of objects that have been segmented into a fine segmentation class. Then, a contour optimization algorithm is applied to at least one of the second set of objects in order to refine that object's contour boundary. Subsequently, that object is identified as corresponding to a lymph node.

  • Patent number: 10956712
    Abstract: A hardware system is configured for, and a method of, generating detail-rich gradient-based disparity maps in real-time using an automated gradient-based disparity map classification process that is scalable, can be used under different environment conditions with little to no restrictions, and whose level of precision can be adjusted in a scalable manner. Highly accurate cross-spectral stereo matching methods may be used for search and rescue operations and work at day time and night time using current and past visual and full infrared imaging to generate, classify, and identify scenes in real-time with minimum constraints. Such system and methods may be used to improve operations of existing search and rescue equipment.

  • Patent number: 10939874
    Abstract: An automatic classification method for distinguishing between indolent and clinically significant carcinoma using multiparametric MRI (mp-MRI) imaging is provided. By utilizing a convolutional neural network (CNN), which automatically extracts deep features, the hierarchical classification framework avoids deficiencies in current schemes in the art such as the need to provide handcrafted features predefined by a domain expert and the precise delineation of lesion boundaries by a human or computerized algorithm. This hierarchical classification framework is trained using previously acquired mp-MRI data with known cancer classification characteristics and the framework is applied to mp-MRI images of new patients to provide identification and computerized cancer classification results of a suspicious lesion.

  • Patent number: 10922899
    Abstract: A method of interactive quantification of digitized 3D objects includes a determination of coordinates of observed screen space using a camera that senses the position of pupils of the operator gazing on the screen. Dimensions of studied sub-volume of VOI block of dimensions of Sx, Sy, Sz or VOI cylinder of dimensions of Sx=Sy=Sxy are defined. An analyzed particle and VOI position is selected. A VOI is visualized. Observed space is corrected by VOI visualization. The last level is selected by gaze of the operator from the sequence of probe levels and the gaze is focused on the last level on which the particle is still visible. The property of the marked particle in 3D space is verified, and marked with a color mark. The mark position is determined by interpolation or by finding a representative point.
