  • Patent number: 11600000
    Abstract: An image processing method includes: calculating an area of a first label of a first medical image of a plurality of medical images with a plurality of labels; obtaining a first determination result based on whether the area of the first label is greater than a threshold value; obtaining a second determination result based on whether a second medical image of the medical images adjacent to the first medical image includes a second label overlapping a first projection area of the first label on the second medical image; and selectively deleting the first label on the first medical image according to the first determination result and the second determination result. The present disclosure further provides an image processing system to perform the image processing method.

  • Patent number: 10222442
    Abstract: A method and apparatus for single carrier wideband magnetic resonance imaging (MRI) data acquisition are provided. The method includes the following steps: exciting a slice or slab with the use of RF pulse and a slice/slab selection gradient; applying a phase encoding gradient along a phase encoding direction and reducing a FOV along the phase encoding direction by a factor of W through k-space subsampling; applying a frequency encoding gradient along a frequency encoding direction and increasing a FOV along the frequency encoding direction by a factor of Wf; and applying a separation gradient along the phase encoding direction during the frequency encoding duration and k-space data acquisition.

  • Patent number: 9632157
    Abstract: The present invention discloses a 3-dimension magnetic resonance imaging method which comprises: applying a slab selection gradient to a subject; transmitting a radiofrequency pulse to the subject, and exciting a slab of the subject to produce magnetic resonance signals with a continuous frequency bandwidth; performing a spatial encoding gradient across three dimensions to encode the magnetic resonance signals, wherein an equivalent encoded field of view which along the selected acceleration direction is controlled by the spatial encoding gradient, and the equivalent encoded field of view is shorter than the excited slab size of the subject; applying a separation gradient along with the spatial encoding gradient; and receiving and reconstructing the encoded magnetic resonance signals to produce 3D images.

  • Patent number: 8687133
    Abstract: A stereoscopic display device includes a display panel, two different polarized backlights and a synchronization module. The display panel is used to alternately generate first visible images and second visible images. The two different polarized backlights are to alternately illuminate the display panel so as to output the first visible images and second visible images, respectively. The synchronization module is used to synchronize the first visible images and second visible images with illumination periods of the respective polarized backlights.

  • Publication number: 20120007856
    Abstract: A stereoscopic display device includes a display panel, two different polarized backlights and a synchronization module. The display panel is to alternately generate left-eye visible images and right-eye visible images. The two different polarized backlights are to alternately illuminate the display panel so as to output the left-eye visible images and right-eye visible images, respectively. The synchronization module is to synchronize the left-eye visible images and right-eye visible images with illumination periods of the respective polarized backlights.
