Open image in new window Fig. 1 After automatic placement by the post-processing software (Examine, Siemens), the VOI was manually defined by the user in order to achieve the best delineation of the trabecular bone and exclusion of any cortical bone.
To achieve this, the VOI was manually defined by the user in order to achieve the best delineation of the trabecular bone and exclusion of any cortical bone (Fig. 1).
Fig. 9 FV highlighted in red by S Fig. 10 Bones can be hidden for better understanding Fig. 11 For better understanding, vessels that do not feed the tumor can be hidden Structure Extraction: A seed point is manually defined by the XRT at the entrance of the hepatic artery on any image from the multiplanar reconstruction (MPR).
More precisely, a k-means clustering (with k = 50) was first applied to the image pixels, and eleven pre-labeled land cover/use classes were manually defined by the operator, by merging initial clusters.
For each tumor, determination of FVs was based on three consecutive steps, structure extraction, target definition, and FV selection, as follows: Structure Extraction: A seed point is manually defined by the XRT at the entrance of the hepatic artery on any image from the multiplanar reconstruction (MPR).
The size of the network and the number of interactors per recognized entity can be manually defined by the user.
The ROI was manually defined in each case by an expert physician.
A method proposed by Shionyu-Mitsuyama et al. (2003) and its extension by Saito et al. (2006) manually defined the fragments for carbohydrates and nucleotide bases, respectively, but these fragments, such as glucose, galactose, guanine, adenine and others, only correspond to a few specific ligands.
First, the VOI was manually defined.
Thus, the ROIs were manually defined.
