چکیده
Figure 2. Comparision of activation maps with and without susceptibility artifacts from SPM2. (a) true activation map. (b) activation map detected from phantoms without susceptibility artifacts. (c) activation map detected from phantoms with susceptiblity artifacts. More false activations are obsevered in (c), and the detected activation regions are spatially shifted relative to the true map (arrows show examples).

Computer-generated fMRI phantoms with motion-distortion interaction.
As an extension of previous work on computer-generated phantoms, more accurate, realistic phantoms are generated by integrating image distortion and signal loss caused by susceptibility variations. With the addition of real motions and activations determined from actual functional MRI studies, these phantoms can be used by the fMRI community to assess with higher fidelity pre-processing algorit...
متن کاملComparison of fMRI statistical software packages and strategies for analysis of images containing random and stimulus-correlated motion
The objectives of this study were to use computer-generated phantoms containing real subject motion to: (1) compare the sensitivity of four commonly used fMRI software packages and (2) compare the sensitivity of three statistical analysis strategies with respect to motion correction. The results suggest that all four packages perform similarly in fMRI statistical analysis with SPM2 having sligh...
متن کاملComparison of functional MRI image realignment tools using a computer-generated phantom.
This study discusses the development of a computer-generated phantom to compare the effects of image realignment programs on functional MRI (fMRI) pixel activation. The phantom is a whole-head MRI volume with added random noise, activation, and motion. It allows simulation of realistic head motions with controlled areas of activation. Without motion, the phantom shows the effects of realignment...
متن کاملQuantification of motion-related artifacts in simulated FMRI data using ICA
I. Drobnjak, C. F. Beckmann, M. Jenkinson Oxford Centre for FMRI of the Brain, University of Oxford, Oxford, United Kingdom, Computing Laboratory, University of Oxford, Oxford, United Kingdom Introduction: FMRI data contain many motion-related artefacts which can limit its usefulness. Many approaches exist to correct for rigid-body motion effects but they struggle to do so in cases when motion ...

♦ Data Issues: Artifacts and Quality In all scientific fields, the primary data are subject to contamination which can severely bias the conclusions. In FMRI, the primary data are time series of 3D images, which can be grossly or subtly damaged by scanner and subject artifacts. Scanner artifacts should be minimized by carrying out daily quality checks with FMRI-like phantom scans, to make sure ...
