For example, a lower window can be used for viewing skeletal structure or soft tissue, while a higher window can be used for simultaneously viewing metal or other high attenuating structures.
By using these sensitivity ratios, we can estimate the primary counts for the lower window: Fig. 2 Concept of modified TEW method: spectra for Tc-99m and primary (Tc-99m) were obtained from phantom measurement and scatter-free radiation source measurement.
For Δ HNPL, we set the midpoint of lower window opening to 0.91 m (3 ft).
It's possible for the windows to have been shipped unlocked, and unwrapping an unlocked window upside down will result in the lower window sash crashing down and most definitely causing damage.
Although the shop was near the headquarters of the London Fire Brigade and the emergency services were quickly on scene, by the time the fire engine arrived intense flames were coming from the lower windows, making it impossible for the fire brigade to position ladders.
As we both turned onto Northern Boulevard, the driver, beaming, lowered his window for his companion to shoot a video on his smartphone.
This is because the lower sub-window for I-123 was placed within the photopeak energy range.
This means that the lower sub-window for I-123, which was narrow and near to the photopeak, caused overestimation of scatter; however, the FiveEW method reduced this scatter overestimation and thereby improved the linearity and reproducibility of activity measurement.
Buildings will have smart controls, automatically raising and lowering window blinds to regulate light and temperature, for example.
But long-term interest rates have risen, and therefore the window for lower interest rates is spent.
