Figure 2 – Reformatted images showing the main coronary arteries of two subjects. Subject 1: 2D Affine + translational motion correction gives superior image quality compared to both 2D translational correction and a gated scan (with ~3x reduction in scan time). Subject 2: 2D motion correction gives similar image quality to the gated scan with ~2x reduction in scan time. Affine correction shows...

introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

Background As has been shown recently, the use of undersampled 3D projection reconstruction (3DPR) and image-based motion correction with 100% acquisition efficiency [1,2] enables highly accelerated coronary MRA (CMRA) with high isotropic resolution. However, streaking artifact from undersampling significantly reduces the apparent signal-to-noise ratio (SNR). Moreover, affine motion correction ...

Background Automated mage registration in cardiac myocardial perfusion is a necessity before quantitative perfusion can be widely accepted in clinical practice. Increasingly complex motion correction algorithms are being developed to deal with cardiac motion. However, the impact of these improvements has not been evaluated in terms of the final clinical diagnosis. Advanced motion correction met...

Introduction: Diffusion weighted imaging (DWI) has become indispensable in clinical routine, especially due to its sensitivity to early stages of brain ischemia. Patient motion during measurements is a major source of artifacts. A distinction must be made between motions during the acquisition of a single diffusion encoded image (intrascan) and movements in between these images (interscan) as w...
