    Abstract: The present invention is capable of determining the location(s) of waste (e.g. nuclear fuel debris, obstacles, contaminated or otherwise radioactive materials), monitoring and inspecting their surroundings, and transporting them, as well as use in repair, construction, and reactor decommissioning work in high radiation environment. Ultrasound (or sound) waves are not subject to interference from radiation. This modality is utilized in the present invention to detect and image waste and/or objects of interest. The system combines the resulting ultrasound (or sound) wave images for detecting waste and/or objects of interest with radiation information acquired by a radiation detector, to generate and adjust new composite images to display. For example, the image in the direction of strong radiation is red and the image in the direction of weak radiation is blue. Additionally, the constituent imaging apparatus may be fitted on a drone or robotic system for repair and construction work.

  • Patent number: 11562454
    Abstract: A hybrid collimated probe incorporates two detectors consisting of a scintillating crystal or semiconductor material, such as Cadmium-Zinc-Telluride (CZT). The count rate measured on the rear detector is corrected for the shielding effect of the front detector before the count rate ratio is calculated. This is done by multiplying the rear detector count rate by a factor pre-determined from the thickness and density of the front detector for a specific radionuclide energy. The count rate ratio also must be corrected for the presence of background radiation at the target site. This is done by taking a 3 second average of the count rate over tissue that does not contain a radiotracer sequestered at the site of pathology, but in adjacent tissue that is uniformly perfused by a lower level concentration of the radiotracer circulating in the blood pool background.

  • Patent number: 10997701
    Abstract: The present invention provides a method, system and image to enhance the image contrast of a digital image device while simultaneously compensating for image intensity inhomogeneity, regardless of the source. The present invention corrects intensity inhomogeneities producing a more uniform image appearance. Also, the image is enhanced through increased contrast, e.g., tissue contrast in a medical image. The method makes no assumptions as to the source of the inhomogeneities, e.g., physical device characteristics or positioning of the object being imaged. In the method, the error between the histogram of the spatially-weighted original image and a specified histogram is minimized. The specified histogram may be selected to increase contrast generally or particularly for accentuation, e.g., on localized regions of interest. The weighting is preferably achieved by two-dimensional interpolation of a sparse grid of control points overlaying the image.

  • Patent number: 10478133
    Abstract: Methods and systems are provided for calibrating a nuclear medicine imaging system. In one embodiment, a method comprises: detecting, with a plurality of detectors, photons emitted by a calibration source comprising a radioactive line source and a fluorescence source, while pivoting one or more detectors of the plurality of detectors; and calibrating, with a processor communicatively coupled to the plurality of detectors, each detector of the plurality of detectors based on energy measurements of the detected photons. In this way, a two-point energy calibration of detectors can be performed with a single isotope, and without removing or adjusting a collimator attached to the detector.

    Abstract: A tool can include an X-ray tomography device to evaluate cement in a downhole environment. The X-ray tomography device includes an X-ray beam source configured to transmit an X-ray beam at a first predetermined angle. The beam angle may be set by a capillary device coupled to the X-ray beam source. An energy dispersive, multi-pixel photon detector is configured to count detected backscatter photons received at a second predetermined angle and determine an energy spectrum for the detected photons. A density map of the cement may be generated in response to the number of detected photons. Additional apparatus, systems, and methods are disclosed.

    Abstract: A method and a device for providing reference information for a scan protocol are provided. The method includes: obtaining first basic information and a first pilot image of a patient to be scanned as index information; retrieving a second pilot image that matches the index information from a preset scan protocol database; and outputting a second pilot image, and a second reconstructed image and a second scan protocol in the preset scan protocol database which correspond to the second pilot image as reference information. If the second pilot image matches the index information, the physical condition of a scanned patient corresponding to the second pilot image is similar to that of the patient to be scanned, and the second pilot image, and the second reconstructed image and the second scan protocol in the preset scan protocol database which correspond to the second pilot image are outputted as reference information.

  • Patent number: 10274614
    Abstract: This invention presents a new device to produce images of the gamma field, specially designed for circumstances requiring high efficiency and fast response imaging, by applying the concept of image extraction within a given field of view, through the combination of efficient gamma radiation detectors. Each detector is located inside a shielding, with an area of the detector with no shielding to enter the incident gamma radiation detector with a plurality of angles in relation to the normal outgoing central axis to the surface of the detector through the unshielded area, where that central axis is divergent in relation to the outgoing central axes of neighboring detectors.

  • Patent number: 10235744
    Abstract: The present invention provides a method and apparatus to enhance the image contrast of a digital image device while simultaneously compensating for image intensity inhomogeneity, regardless of the source. The present invention corrects intensity inhomogeneities producing a more uniform image appearance. Also, the image is enhanced through increased contrast, e.g., tissue contrast in a medical image. The method makes no assumptions as to the source of the inhomogeneities, e.g., physical device characteristics or positioning of the object being imaged. In the method, the error between the histogram of the spatially-weighted original image and a specified histogram is minimized. The specified histogram may be selected to increase contrast generally or particularly for accentuation, e.g., on localized regions of interest. The weighting is preferably achieved by two-dimensional interpolation of a sparse grid of control points overlaying the image.

  • Patent number: 10206647
    Abstract: A radiographic image capturing device includes the following. A two-dimensional array of radiation detectors generate electrical charges corresponding to a dose of incident radiation. A control unit reads the electrical charges discharged from the radiation detectors in a form of image data. The control unit has radiographic modes including a still image mode for still image radiography, a moving image mode for moving image radiography, and a continuous radiographic mode for reading the image data without distinguishing between the still image radiography and the moving image radiography. The control unit selects the continuous radiographic mode to sequentially read the image data when an instruction on performing the still image radiography or the moving image radiography is not sent from an external control device or a user or when the radiographic mode is unknown due to communication failure with the external control device.
