DeepPhaseCut: Deep Relaxation in Phase for Unsupervised Fourier Phase Retrieval

Eunju Cha, Chanseok Lee, Mooseok Jang +1

Fourier phase retrieval is a classical problem of restoring a signal only from the measured magnitude of its Fourier transform. Although Fienup-type algorithms, which use prior kno…

Two-Stage Deep Learning for Accelerated 3D Time-of-Flight MRA without Matched Training Data

Hyungjin Chung, Eunju Cha, Leonard Sunwoo +1

Time-of-flight magnetic resonance angiography (TOF-MRA) is one of the most widely used non-contrast MR imaging methods to visualize blood vessels, but due to the 3-D volume acquisi…

Unsupervised Deep Learning for MR Angiography with Flexible Temporal Resolution

Eunju Cha, Hyungjin Chung, Eung Yeop Kim +1

Time-resolved MR angiography (tMRA) has been widely used for dynamic contrast enhanced MRI (DCE-MRI) due to its highly accelerated acquisition. In tMRA, the periphery of the k-spac…

Boosting CNN beyond Label in Inverse Problems

Eunju Cha, Jaeduck Jang, Junho Lee +2

Convolutional neural networks (CNN) have been extensively used for inverse problems. However, their prediction error for unseen test data is difficult to estimate a priori since th…

k-Space Deep Learning for Parallel MRI: Application to Time-Resolved MR Angiography

Eunju Cha, Eung Yeop Kim, Jong Chul Ye

Time-resolved angiography with interleaved stochastic trajectories (TWIST) has been widely used for dynamic contrast enhanced MRI (DCE-MRI). To achieve highly accelerated acquisiti…
