  • Patent number: 11185311
    Abstract: Extracorporeal motion (130) relative to a medical subject being imaged is detected, through the imaging or from motion detectors on the imaging probe, and either backed out of the medical images so that it can be determined whether lung sliding exists or measured to determine whether lung sliding detection is to be suspended due to excessive extracorporeal motion. Image sub-regions (164, 168) corresponding to respective ones of the images are selected for image-to-image comparison such that the selected sub-regions contain only body tissue that is, with respect to imaging depth in the acquiring of the images, shallower than an anatomical landmark within the images. Based on a result of the comparing, lung sliding detection that entails examining image data deeper than the landmark may be initialized.

  • Patent number: 10588595
    Abstract: A device and method for initializing an ultrasound beamformer to image an object based on a tool-pose-estimation of the object include an ultrasound imaging array and an object. The ultrasound imaging array operates with the beamformer. The object has a sensor external to the ultrasound imaging array. The tool-pose-estimation includes an estimation of the location and/or the orientation of the object. The tool-pose-estimation of the object is derived by a processor that receives an output of the sensor disposed on the object external to the imaging array that operates with the beamformer. The processor supplies the tool-pose-estimation to the beamformer to initialize the beamformer using the tool-pose-estimation for operating the imaging array.

  • Patent number: 10514478
    Abstract: Systems and methods for generating a three-dimensional image of a proppant-filled hydraulically-induced fracture in a geologic formation are provided. The image may be generated by capturing electromagnetic fields generated or scattered by the proppant-filled fracture, removing dispersion and/or an attenuation effects from the captured electromagnetic fields, and generating the image based on the dispersion and/or attenuation corrected fields. Removing the dispersion and/or attenuation effects may include back propagating the captured electromagnetic fields in the time domain to a source location. The image may be generated based on locations at which the back propagated fields constructively interfere or may be generated based on a model of the fracture defined using the back propagated fields.

  • Patent number: 10489907
    Abstract: A medical scanner generates a medical image that may have an artifact. A machine-learnt detector, trained from a library of many different types of artifacts in images, detects any artifact in the medical image for a patient. The location of the artifact is highlighted, providing an indication of possible artifact where the image may otherwise appear to represent anatomy or pathology. A machine-learnt network may be applied to the medical image to determine a correction, such as different scan or reconstruction, to remove or reduce the artifact.
