Abstract: A white cane capable of emitting light throughout its body is provided. The white cane comprises a white cane main body, a warning assembly, a control module and a battery. A whole cane body of the white cane can emit light, and auditory prompts can be passed to others with a loudspeaker, so that visibility of a blind user for others is obviously improved, and then traveling safety of blind people is greatly improved. A light strip of the white cane can emit various colors of light, and applicability is balanced during day and night, so that blind people can travel out all the day comfortably.

Abstract: A method for reconstructing dynamic contrast-enhanced (DCE) MR images includes receiving a plurality of continuous free-breathing DCE images, the plurality of images obtained with a contrast, sorting the images by identifying a respiratory phase associated with each of the continuous free-breathing DCE images, reconstructing the plurality continuous free-breathing DCE images into a 4D respiratory motion-resolved image, obtaining 3D deformable motion vector fields (MVFs), and utilizing a deep learning based motion transformation integrated forward-Fourier (DL-MOTIF) model and the 3D deformable MVFs to reconstruct the DCE MR images.
