Contrast-induced nephropathy (CIN) develops after the injection of iodinated contrast media. This is a post hoc analysis of the data obtained from the TRUST study, which was a prospective, multicentre, observational study conducted to evaluate the safety and tolerability of the contrast medium iopromide in patients undergoing cardiac catheterization from(More)
Fluorescence molecular tomography (FMT) is a fast-developing optical imaging modality that has great potential in early diagnosis of disease and drugs development. However, reconstruction algorithms have to address a highly ill-posed problem to ful ̄ll 3D reconstruction in FMT. In this contribution, we propose an e±cient iterative algorithm to solve the(More)
Fluorescence molecular tomography (FMT) has been a promising imaging tool that provides convenience for accurate localization and quantitative analysis of the fluorescent probe. In this study, we present a reconstruction method combining sorted L-one penalized estimation with an iterative-shrinking permissible region strategy to reconstruct fluorescence(More)
Fluorescence molecular tomography (FMT) is a promising imaging technique that allows in vivo visualization of molecular-level events associated with disease progression and treatment response. Accurate and efficient 3D reconstruction algorithms will facilitate the wide-use of FMT in preclinical research. Here, we utilize L1/2-norm regularization for(More)
Tag-based image retrieval (TBIR) has drawn much attention in recent years due to the explosive amount of digital images and crowdsourcing tags. However, the TBIR applications still suffer from the deficient and inaccurate tags provided by users. Inspired by the subspace clustering methods, we formulate the tag completion problem in a subspace clustering(More)
OBJECTIVES The PLATINUM China clinical trial evaluated the safety and effectiveness of the thin-strut, everolimus-eluting, platinum-chromium PROMUS™ Element™ stent (PtCr-EES) (Boston Scientific, Marlborough, MA) for the treatment of patients in China. BACKGROUND Clinical outcomes from the PtCr-EES have not been evaluated in patients from China, nor has it(More)
A digital correlation method to measure the phase difference between two sinusoidal signals is presented. In order to meet the requirements of real-time in practice application, a FPGA is employed to implement the measurement algorithm. In the correlation analysis by FPGA, a CORDIC algorithm is adopted to solve inverse trigonometric function, and thereby(More)
Tag-based image retrieval (TBIR) has drawn much attention in recent years due to the explosive amount of digital images and crowdsourcing tags. However, TBIR is still suffering from the incomplete and inaccurate tags provided by users, posing a great challenge for tag-based image management applications. In this work, we proposed a novel method for image(More)
Fluorescence molecular tomography (FMT) is a promising imaging modality that offers the possibilities to monitor cellular and molecular function in vivo. However, accurate and stable reconstruction of fluorescence-labeled targets remains a challenging problem. In this contribution, a two-stage reconstruction algorithm that combines sparse regularization(More)
