Multiple Measurement Vectors ISAR Imaging Algorithm Based on a Class of Linearized Bregman Iteration

Leida xuebao, 2016
This study aims to enable steady and speedy acquisition of Inverse Synthetic Aperture Radar (ISAR) images using sparse echo data. To this end, a Multiple Measurement Vectors (MMV) ISAR echo model is studied.

Bistatic image processing for a 32 x 19 inch model aircraft using scattered fields obtained in the OSU-ESL compact range [PDF]

Inverse Synthetic Aperture Radar (ISAR) images for a 32 in long and 19 in wide model aircraft are documented. Both backscattered and bistatic scattered fields of this model aircraft were measured in the OSU-ESL compact range to obtain these images.

Age is not a primary risk factor for anterior cruciate ligament injury—A comprehensive review of anterior cruciate ligament injury and reinjury risk factors confounded by young patient age

Knee Surgery, Sports Traumatology, Arthroscopy, Volume 34, Issue 1, Page 17-33, January 2026.
Abstract Revision surgery after anterior cruciate ligament reconstruction (ACL‐R) is hypothesized to be the result of an interplay between factors associated with the anatomy, physiological characteristics and environment of the patient. The multifactorial nature of revision ACL‐R risk is difficult to quantify, and evidence regarding the independent ...

Abdominal simultaneous 3D water T1 and T2 mapping using a free‐breathing Cartesian acquisition with spiral profile ordering

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 268-285, January 2026.
Abstract Purpose To develop a method for abdominal simultaneous 3D water T1$$ {T}_1 $$ (wT1$$ \mathrm{w}{T}_1 $$) and T2$$ {T}_2 $$ (wT2$$ \mathrm{w}{T}_2 $$) mapping with isotropic resolution using a free‐breathing Cartesian acquisition with spiral profile ordering (CASPR) at 3 T.

Semi-Supervised Deep Learning for Fully Convolutional Networks

, 2017
Deep learning usually requires large amounts of labeled training data, but annotating data is costly and tedious. The framework of semi-supervised learning provides the means to use both labeled data and arbitrary amounts of unlabeled data for training ...

Motion‐robust T2∗$$ {\mathrm{T}}_2^{\ast } $$ quantification from low‐resolution gradient echo brain MRI with physics‐informed deep learning

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 346-362, January 2026.
Abstract Purpose T2∗$$ {\mathrm{T}}_2^{\ast } $$ quantification from gradient echo magnetic resonance imaging is particularly affected by subject motion due to its high sensitivity to magnetic field inhomogeneities, which are influenced by motion and might cause signal loss. Thus, motion correction is crucial to obtain high‐quality T2∗$$ {\mathrm{T}}_2^
