Objective: We present a Matlab-based tool to convert electrocardiography (ECG) information from paper charts into digital ECG signals. The tool can be used for long-term retrospective studies of cardiac patients to study ...
Near Real-Time Computer Assisted Surgery for Brain Shift Correction Using Biomechanical Models [0.03%]
基于生物力学模型的脑变形矫正近实时计算机辅助手术系统

Kay Sun et al.
Conventional image-guided neurosurgery relies on preoperative images to provide surgical navigational information and visualization. However, these images are no longer accurate once the skull has been opened and brain shift occurs. To acco...
Quantitative Assessment of Single-Image Super-Resolution in Myocardial Scar Imaging [0.03%]
单幅图像超分辨在心肌瘢痕成像中的定量评估

Four-dimensional computed tomography (4DCT) provides not only a new dimension of patient-specific information for radiation therapy planning and treatment but also a challenging scale of data volume to process and analyze. Manual analysis u...
Constrained T p V Minimization for Enhanced Exploitation of Gradient Sparsity: Application to CT Image Reconstruction [0.03%]
利用梯度稀疏性的约束T p V最小化方法在CT图像重建中的应用研究
Emil Y Sidky,Rick Chartrand,John M Boone et al.
Emil Y Sidky et al.
Exploiting sparsity in the image gradient magnitude has proved to be an effective means for reducing the sampling rate in the projection view angle in computed tomography (CT). Most of the image reconstruction algorithms, developed for this...
Novel Flurometric Tool to Assess Mitochondrial Redox State of Isolated Perfused Rat Lungs after Exposure to Hyperoxia [0.03%]
一项新荧光检测工具：评估大鼠肺生物体外灌注后暴露于高氧状态下的线粒体还原氧化状态
R Sepehr,S H Audi,K S Staniszewski et al.
R Sepehr et al.
Recently we demonstrated the utility of optical fluorometry to detect a change in the redox status of mitochondrial autofluorescent coenzymes NADH (Nicotinamide Adenine Dinucleotide) and FAD (oxidized form of Flavin Adenine Dinucleotide (FA...
Spatial Mutual Information as Similarity Measure for 3-D Brain Image Registration [0.03%]
基于空间互信息的三维脑图象配准的相似度测量方法研究
