Abstract The Unet is attempted to be slimmed for compressed‐sensing cardiac cine magnetic resonance imaging. Despite the excellent performance of the U‐net, its heavy structure and long training time restrict its applications in an environment wi

This case study examined the effect of Korean Medicine on a 72-year old male with a habitual history of smoking and drinking, and a family history of hypertension who had suffered an acute stroke. A couple of months later he complained of upper extre

We propose the "Tile-net" method based on dividing an image into smaller tiles. Using the tile as the input to the neural network, the network is simplified substantially. The Tile-net learns at a much faster rate than the networks without tiling. Th

We introduce an adaptive search region decision algorithm to improve the speed of GPU-based motion estimation which generally adopts the full-search. The motion feature of the current block is estimated by MAP (Maximum A Posterior) estimation with th

Correction of an inhomogeneous magnetic field is proposed using partial differential phases in magnetic resonance imaging. Estimation of the inhomogeneous magnetic field from a measured phase is not an easy task due to phase wrapping and chemical-dep

In cardiac magnetic resonance imaging (CMRI), heart and respiratory motions are one of main obstacles in obtaining diagnostic quality of images. To synchronize CMRI to the physiological motions, ECG and respiratory gatings are commonly used. In this
