Imaging data from the phantoms using a calibrated PET CT scanner gave values consistent with the calibrated activity concentrations within experimental uncertainties.
Then, the intensity V u,v) of the virtual image is given as the average of N c laser scanner intensity values C(p j ), V u,v) = frac{1}{N_{c}}sum_{p_{j} in mathcal{N}} C {boldsymbol{p}}_{j}),,. (4).
The measure of FM and %BF calculated by DEXA was received as a printout from the scanner and values were entered in the study pro forma.
Values consistently lower than the true activity concentration were a maximum of 2.5% and are likely to originate from the calibration factor between the dose calibrator and PET scanner, although this value is well within the locally set tolerance of 5%.
The ADC values used in diffusion-weighted imaging are dependent on scanner and b-values.
On the other hand, for scanner II, FSV values were significantly lower after an additional erosion (4.0 ± 1.6 %, p < 0.001), showing that partial volume effects still play a minor but significant role for this older scanner.
After scanning the Genechips in an Affymetrix 2500 scanner, transcript expression values were estimated using the GC-RMA function provided by Refiner 3.1 (Genedata, Basel, Switzerland) and statistical analysis was performed using Analyst 3.1 (Genedata).
Arrays were scanned with Agilent's dual laser-based scanner and intensity values were read and processed with Agilent's Feature Extraction software version 8.0 with default parameters.
The ADC map is automatically generated on a voxel-by-voxel basis on most scanners, and the value of each voxel describes the relationship between the logarithm of the signal intensity and the b value.
BeadChip arrays were scanned with Illumina BeadStation Scanner and data values with detection scores were compiled using BeadStudio v1.5.1.3 (Illumina) and imported into GeneSpring GX v7.3.1 (Agilent) for data analysis.
