Sentence examples for spillover activity from inspiring English sources

Proprietary software was used to correct for both background and spillover activity from one window into another and to calculate regional myocardial blood flow.

Corrections for fractional blood volume, partial volume effects and spillover activity from left-ventricular blood pool to tissue were calculated as described elsewhere [ 19].

The image quality parameters to be determined using this phantom are (i) recovery coefficients for the differently sized rods, indicative of spatial resolution, (ii) spillover of activity into the cold air and water compartments, expressing the scatter performance, and (iii) uniformity of measured activity in the background compartment that indicates the signal-to-noise ratio.

Firstly, no corrections were made for spillover of activity between arterial blood and myocardium.

To reduce partial volume effects and spillover of activity from surrounding organs, the outer layer of voxels included in each cluster was eroded before input functions were obtained.

Furthermore, spillover of activity from the myocardium is a serious problem in cardiac ventricular image-derived IF in rats and mice.

Examples of 'image parameters' are spatial resolution as indicated by small structures in the image (small spheres or rods used to calculate recovery coefficients), image uniformity (signal-to-noise ratios, percentage standard deviation), spillover of activity into cold regions and quantification (pixel values indicating Bq/cm3).

For very intense lesions, spillover of activity into adjacent voxels can make them appear larger than they are.

The spatial resolution of PET (10 mm) and the spillover of activity from the primary tumour limit the detection of these lymph nodes adjacent to the primary.

The free acid of tafluprost is an FP prostanoid receptor agonist with some spillover of activity on the prostaglandin E receptor 3 (EP3) [ 8, 9].

The true bias values are particularly high for ROI3, which is the defect region, because of activity spillover due to PET partial volume effect.
