  • Publication number: 20210279847
    Abstract: Systems and methods are provided for computed tomography (CT) imaging. In one embodiment, a method comprises adaptively blending at least two input image volumes with different spatially-variant noise characteristics to generate an output image volume with uniform noise throughout the output image volume. In this way, images may be reconstructed from projection data with data redundancy without introducing image artifacts from stitching images or variance in image noise due to the data redundancy.

  • Publication number: 20210212642
    Abstract: Various methods and systems are provided for displaying to an operator an attenuation map of a filter relative to a current location of an anatomical feature of a subject; and in response to the anatomical feature being within a region of the attenuation map, prompting an operator to reposition the subject. In this way, centering of the anatomical feature relative to an attenuation system may be facilitated for improved image quality.

  • Patent number: 10638991
    Abstract: A system for imaging a subject with a contrast agent is provided. The system includes an X-ray source, an X-ray detector, and a controller. The X-ray source is operative to transmit X-rays through the subject. The X-ray detector is operative to receive the X-rays after having passed through the subject. The controller is in electronic communication with the X-ray source and the X-ray detector and operative to: generate a target contrast level based at least in part on a contrast adjustment factor; determine when a level of the contrast agent in a first plurality of images of the subject acquired via the X-ray source and the X-ray detector reaches the target contrast level; and acquire a second plurality of images of the subject via the X-ray source and the X-ray detector after the level of the contrast agent has reached the target contrast level.

  • Publication number: 20200134883
    Abstract: Methods and systems are provided for reconstructing images with a tailored image texture. In one embodiment, a method comprises acquiring projection data, and reconstructing an image from the projection data with a desired image texture. In this way, iterative image reconstruction techniques may be used to substantially reduce image noise, thereby enabling a reduction in injected contrast and/or radiation dose, while preserving an image texture familiar from analytic image reconstruction techniques.

  • Patent number: 10561391
    Abstract: Methods and systems are provided for automatic exposure control in a computed tomography imaging system. In one embodiment, a method comprises estimating attenuation properties of a subject along a direction, and varying, based on the attenuation properties, a helical pitch along the direction during a scan of the subject. In this way, a desired image quality can be maintained while reducing radiation dose, without modulating tube current.

  • Patent number: 10383589
    Abstract: Methods and systems are provided for direct monochromatic image generation for spectral computed tomography. In one embodiment, a method comprises acquiring projection data during a scan of a subject, reconstructing a low energy image and a high energy image from the projection data, and generating a monochromatic image from the low energy image and the high energy image. In this way, a monochromatic image may be generated directly from low and high energy images with a substantial reduction in image noise, especially when compared to a monochromatic image generated indirectly from material density images.

  • Patent number: 10335096
    Abstract: A method is provided. The method includes partially supporting a subject to be imaged on a board extending from a mobile patient transport into a gantry bore of a stationary computed tomography (CT) imaging system while partially supporting both the subject and the board with a cradle extending from a table. The method also includes acquiring a single imaging volume, during an imaging scan with the stationary CT imaging system, without moving the subject.

  • Patent number: 9931095
    Abstract: According to some embodiments, system and methods are provided comprising determining one or more image locations at which motion occurred within an image volume of an object containing movable anatomical features prior to segmenting the movable anatomical features; estimating motion at each of the one or more image locations; correcting one or more motion artifacts in the image volume at each of the one or more image locations, where motion was estimated resulting in the generation of a final motion compensated image; and segmenting one or more features of interest in the final motion compensated image. Numerous other aspects are provided.

  • Patent number: 9858688
    Abstract: Methods and systems are provided for motion compensation in computed tomography imaging. In one embodiment, a method comprises reconstructing at least two images from projection data, calculating a motion metric based on the at least two images, selecting a view-weighting function based on the motion metric, and generating a display from the projection data based on the selected view-weighting function. In this way, an image can be reconstructed with the selected view-weighting function which down-weights slices in the image containing motion artifacts. As a result, the image quality of the reconstructed image may be improved with computational efficiency.

  • Patent number: 9836862
    Abstract: Methods and systems are provided for boosting the contrast levels in an image reconstructed from projection data acquired at a single energy. In one embodiment, a method comprises modifying projection data corresponding to a material based on an absorption behavior of the material at a selected energy, wherein the projection data is acquired at an energy higher than the selected energy. In this way, contrast levels may be enhanced in an image reconstructed from projection data acquired at a typical single energy as though the image were reconstructed from projection data acquired at a lower energy.

  • Patent number: 9683948
    Abstract: Systems and methods for iterative multi-material correction are provided. A system includes an imager that acquires projection data of an object. A reconstructor reconstructs the acquired projection data into a reconstructed image, utilizes the reconstructed image to perform a multi-material correction on the acquired projection data to generate a multi-material corrected reconstructed image, and utilizes the multi-material corrected reconstructed image to perform one or more iterations of the multi-material correction on the projection data to generate an iteratively corrected multi-material corrected image.
