Algebraic reconstruction techniques require about half the number of projections as that of Fourier backprojection methods, which makes these methods safer in terms of required radiation dose. Algebraic reconstruction technique (ART) and it...
High-Performance 3D Compressive Sensing MRI Reconstruction Using Many-Core Architectures [0.03%]
基于多核架构的高性能三维压缩感知磁共振成像重建技术
Daehyun Kim,Joshua Trzasko,Mikhail Smelyanskiy et al.
Daehyun Kim et al.
Compressive sensing (CS) describes how sparse signals can be accurately reconstructed from many fewer samples than required by the Nyquist criterion. Since MRI scan duration is proportional to the number of acquired samples, CS has been gai...
Biomedical imaging modality classification using combined visual features and textual terms [0.03%]

We describe an approach for the automatic modality classification in medical image retrieval task of the 2010 CLEF cross-language image retrieval campaign (ImageCLEF). This paper is focused on the process of feature extraction from medical ...
Deconvolution-Based CT and MR Brain Perfusion Measurement: Theoretical Model Revisited and Practical Implementation Details [0.03%]
基于反卷积的CT和MR脑灌注测量：理论模型再探讨及实用实施细节
Andreas Fieselmann,Markus Kowarschik,Arundhuti Ganguly et al.
Andreas Fieselmann et al.
Deconvolution-based analysis of CT and MR brain perfusion data is widely used in clinical practice and it is still a topic of ongoing research activities. In this paper, we present a comprehensive derivation and explanation of the underlyin...
On the Usage of GPUs for Efficient Motion Estimation in Medical Image Sequences [0.03%]

The goal of this study was to provide a feasibility assessment for PET imaging of multiple sclerosis (MS) lesions based on their decreased myelin content relative to the surrounding normal-appearing brain tissue. The imaging agent evaluated...
Heterogeneous computing for vertebra detection and segmentation in x-ray images [0.03%]
异构计算在X光图像中椎骨检测和分割中的应用
Fabian Lecron,Sidi Ahmed Mahmoudi,Mohammed Benjelloun et al.
Fabian Lecron et al.
The context of this work is related to the vertebra segmentation. The method we propose is based on the active shape model (ASM). An original approach taking advantage of the edge polygonal approximation was developed to locate the vertebra...
Effect of Localized Mechanical Indentation on Skin Water Content Evaluated Using OCT [0.03%]
基于OCT的皮肤含水量Indentation效应研究

Abhijit A Gurjarpadhye et al.
The highly disordered refractive index distribution in skin causes multiple scattering of incident light and limits optical imaging and therapeutic depth. We hypothesize that localized mechanical compression reduces scattering by expulsing ...
Image processing techniques for assessing contractility in isolated neonatal cardiac myocytes [0.03%]
用于评估新生心肌细胞单个心房肌细胞收缩功能的图像处理技术
Carlos Bazan,David Torres Barba,Peter Blomgren et al.
Carlos Bazan et al.
We describe a computational framework for the quantitative assessment of contractile responses of isolated neonatal cardiac myocytes. To the best of our knowledge, this is the first report on a practical and accessible method for the assess...
A framework of vertebra segmentation using the active shape model-based approach [0.03%]
一种基于主动形状模型的椎骨分割方法
