  • Publication number: 20200219251
    Abstract: An image is generated where an edge of a structure in a subject is sharpened with reducing streak artifacts, within a short amount of time. X-rays at multiple angles are applied to the subject placed in imaging space, and a distribution of X-rays strength passing through the subject is detected to obtain raw data associated with multiple views. After smoothing the raw data associated with multiple views, image reconstruction is performed to generate a smoothed image of a predetermined region to be imaged in the imaging space. In the smoothed image, more intense sharpening process is applied to pixels in a region of a central part of the subject, than the pixels in a region of a peripheral part of the subject.

  • Publication number: 20200202499
    Abstract: A medical image processing device and a corresponding method are provided that can extract and enhance a signal in a medical image. A medical image processing device that applies image processing to a medical image, the device including an acquiring unit that acquires an original image, a first extraction unit that extracts a local bias component image, a creating unit that decomposes a difference image between the original image and the local bias component image into at least two frequency bands and creates a low-frequency component image formed of a component in the lowest frequency band, a second extraction unit that extracts a local bias component low-frequency image that is a local bias component of the low-frequency component image, and a computing unit that multiplies the local bias component low-frequency image by a gain, adds to the local bias component image, and computes a contrast enhanced image.

  • Publication number: 20200151920
    Abstract: The present invention provides an image reconstruction apparatus and an image reconstruction method, both of which achieve reduction in a granular noise and a streak-like artifact both contained in a reconstruction image, and a clear structure boundary as well The image reconstruction apparatus configured to generate a reconstruction image includes a noise reduction section that generates a streak reduction image as an image obtained by reducing a streak-like artifact in the reconstruction image, a noise reduction ratio acquisition section that acquires a first noise reduction ratio as a noise reduction ratio to be used for reducing a granular noise while retaining a structure boundary in the reconstruction image, and a second noise reduction ratio as a noise reduction ratio to be used for generating the streak reduction image, and an image addition section that adds an addition image to be generated based on the first noise reduction ratio and the second noise reduction ratio to the streak reduction image.
