Meanings of manual segmentation in anglès

However, manual segmentation is often a time-consuming and subjective process.

We show that the results from automatic segmentation are comparable to those from manual segmentation.

Comparison between the automated and manual segmentation results showed excellent agreement in most brain regions.

Segmentation results were compared to a gold-standard of manual segmentation performed jointly by two human experts.

In addition, we observed significant differences between experts in terms of both manual segmentation and external ratings.

We evaluated whole-brain morphological differences between the groups as well as manual segmentation of regional hippocampal volumes.

Overall, automated liver volumetry based on multiphase CT acquisitions is feasible and more rapid than manual segmentation.

DWI contours were generated by manual segmentation.

We validated their accuracies against manual segmentation.

Results: For simulated phantom lesions, the lesion geometry was accurate despite manual segmentation error and incomplete surface data.

The method combines multi-atlas segmentation, similarity-weighted voting, and a novel learning-based bias correction technique to achieve excellent agreement with manual segmentation.

Semi-automated segmentation followed by manual segmentation had the highest correlation between measured and true tumor volume for all 3 tumor geometries.

Background: An international Delphi panel has defined a harmonized protocol (HarP) for the manual segmentation of the hippocampus on MR.

For volume estimations we used manual segmentation of magnetic resonance images in the axial plane with simultaneous side-by-side view of the sagittal and coronal plane.

Conclusions: Our fully automated algorithm can reproducibly and accurately quantify the area of leakage of clinical-grade FA video and is congruent with expert manual segmentation.

Methods: Brain MRI scans from 94 Hispanic and 94 age- and gender-matched Caucasian MS patients were analyzed using automatic and manual segmentation techniques.
