Sentence examples for background ratios of the from inspiring English sources

Using this model for the tumor and normal tissue uptake, the concentration and tumor to background ratios of the imaging agents were simulated over time (figure 1D).

Varying the doxycycline concentration roughly 2-fold affecthe the background ratios of the strains and the sensitivity of the measurement, but did not change the patterns of selection observed.

The signal to background ratio of the ISMB containing two Cy3 moieties was above 100, whereas that with one Cy3 was 30.

The first model (ωb) evaluated the background ratio of the whole family, assuming all members evolved at the same rate.

This strategy allowed us to enhance the signal intensity and increase the signal to background ratio of the probes by trapping the released fluorophore in lysosomes once cleaved by a protease.

We obtained similar imaging contrast with the A11 minibody in both LAPC-9 and Capan-1 models at 21 h with tumor to background ratios of 4.8 in the LAPC-9 model and 4.2 in the Capan-1 model.

The resulting images show no discernible fluorescence signals and possess signal to background ratios of 1, implying that the substrate complexes have exceptionally low background reactivity with cells.

To estimate the spatial resolution of the differently processed image data and to test the stability of BF, we performed a measurement with a water-filled cylinder phantom containing six spherical inserts (volume range 0.5-26.5 mL) at a target to background ratio of 7. The phantom data were acquired in list mode using an in-house solution [10].

However, due to the large signal-to-background ratio of the lasing spectra, the spectral position of the lasing peak can be localized to a much higher precision using peak fitting.

In this example, the only visual difference between the images reconstructed by both approaches is that the target-background ratio of the image obtained by the group-sparsity approach is better than the target-background ratio of the image obtained by the low-rank sparse decomposition approach.

In a second set of experiments, collagelin and Pc were directly labeled with Tc-99m to avoid the drawbacks of high, non-specific liver uptake and slow blood clearance which could be attributed to streptavidin, and impaired the target-to-background ratio of the images.
