Objective: Free-breathing abdomen imaging requires non-rigid motion registration of unavoidable respiratory in three-dimensional undersampled data sets. In this work, we introduce an image method based on the convolutional neural network (CNN) to obtain motion-free abdominal images throughout cycle. Methods: Abdominal were acquired from 10 volunteers using a 1.5 T MRI system. The signal was extracted central-space spokes, and reordered three bins according corresponding breathing signal....
Abstract In this article, a novel multiple input output (MIMO) antenna with compact structure and diverse radiation patterns is designed for wireless communication device.

A rehabilitation robot plays an important role in relieving the therapists’ burden and helping patients with ankle injuries to perform more accurate effective training. However, a majority of current robots are rigid have drawbacks terms complex structure, poor flexibility lack safety. Taking advantages pneumatic muscles’ good light weight, we developed novel two degrees freedom (2-DOF) parallel compliant actuated by muscles (PMs). To solve PM’s nonlinear characteristics during operation...
