Significados de backscatter en inglés

Neither emulsion manifested significant ultrasonic backscatter until avidin was added.

So backscatter systems are very good at imaging organic material -much better than dual-energysystems.

Conclusion: OCT can effectively differentiate normal cortex from intracortical melanoma based on variations in optical backscatter.

Things dense enough to hopefully block the infrared and backscatter and heartbeat sensors Star Helix carried.

Changes in optical backscatter intensity were used to identify regions of tumor and to locate tumor margins.

Avidin-induced aggregation produced a marked enhancement in backscatter from the biotinylated but not from the control emulsion.

Similarly, backscatter x-ray scanners send out low-intensity beams, and watch how the x-ray photons get reflected back.

Ultrasonic contrast agents are used to enhance backscatter from blood and thus aid in delineating blood from surrounding tissue.

Results: Two-dimensional images showed increased optical backscatter from regions of tumor, which was quantitatively used to determine the tumor margin.

Arterial samples imaged under pressure and in a collapsed state underwent dimensional changes but exhibited similar levels of backscatter amplitude.

AXB was also found to have better dose predictions than AAA and CCC at the tissue interfaces where backscatter occurs.

The current knowledge is placed in the context of integrated backscatter and the future of echocardiographic based tissue characterisation is discussed.

Acquisition rates were fast enough to capture dynamic changes in optical backscatter which corresponded to thermal tissue damage during laser ablation.

Already, there's a push to install scanners that show travelers' naked bodies through clothing, using either millimeter wave or backscatter X-ray imaging.

The results suggest that quantitative integrated backscatter is a sensitive parameter for detecting both early and old myocardial infarction by cardiac tissue characterization.

Bland-Altman analysis revealed best agreement for the birefringence measurements, followed by backscatter intensity, and depolarization, when limiting the analysis to areas of meaningful birefringence.
