Region of interest (ROI) analysis is a widely used method for the analysis of DTI data. An anatomically defined region—either based on anatomical borders or a geometrical shape—is used to extract DTI measures for each subject, which can later be analyzed statistically. ROI analysis can be ...
Region of interest ROI Use an image analysis software package to define a region of imterest. The average voxel value within the region is calculated. VOI Volume of interest can be defined by connecting several ROIs defined on multiple contiguous planes into a single VOI. The error due to cou...

We present a region-of-interest (ROI)-based analysis framework for detecting such a group variation. This framework includes two main techniques: ROI-based registration via large deformation diffeomorphic metric surface mapping and a multivariate testing using a Gaussian random field (GRF) model on ...
Selecting regions of interest (ROI) is a common step in medical image analysis across all imaging modalities. An ROI is a subset of an image appropriate for the intended analysis and identified manually by experts. In modern pathology, the analysis invol

Region of interest, ROI, analysis--confidence in derived parameters? A large proportion of quantitative analysis in the field of diagnostic nuclear medicine relies on the manual definition of the ubiquitous region of interest (ROI) on the gamma camera image. Ways in which errors, sometimes large ...

The reproducibility, precision and accuracy of estimating tensor metrics are affected by SNR and analytic methodologies, such as operator-dependent manual region-of-interest (ROI) analysis for a single subject DTI data and operator-independent tract-based spatial statistics (TBSS)13 for analyzing multi...
This analysis helps to highlight the method ability to distinguish between safe and unsafe routes considering an actual sea-state (for instance, from weather forecasts). The area of interest is the Pelagos area slightly enlarged. The two scenarios have been extracted by the forecasts performed in...
