Sentence examples for the equivalent count from inspiring English sources

Three-hundred milligrams of bread crust or the equivalent counts of viable bacteria (pelleted from MRS broth and washed once with PBS) were suspended in 2.5 mL saline in 30 mL glass vials, then 2.5 mL of double-concentrated simulated gastric juice was added (pH 2.5, 3200 units/mL pepsin, 7.2 mmol/L CaCl2, 3 mmol/L MgCl2, 98 mmol/L NaCl, 24 mmol/L KCl, and 12.8 mmol/L KH2PO4).

Increasing the activity up to the peak in the noise equivalent count curve will improve the count statistics and the detectability of low-contrast features but will also increase the radiation dose to the patient and to the staff involved in administering the activity and scanning the patient.

Maebatake et al. used phantom studies based on the relationship between the noise equivalent count (NEC), as an index of PET image quality and TOF-PET image quality for 18F-FDG PET/CT showing similar results regarding the impact of PSF and TOF [40].

The noise equivalent count rate [NECR], the scatter fraction [SF], and the gamma-prompt fraction [GF] were used to determine the best acquisition parameters for mouse- and rat-sized phantoms filled with 124I.

Using a clinical PET scanner, Ibaraki et al. reported the influence of random events and scatter coincidences from outside the FOV when using a 3D-mode PET scanner as well as the utility of a neck shield, which improved the noise equivalent count ratio by reducing the scatter effects [4].

The line source was filled with an initial activity of 1.04 GBq of 18F, in order to achieve count rates beyond the expected peak of the noise equivalent count rate (NECR) [6, 7].

In this study the noise equivalent count rate (NECR) remained in the linear range with respect to the administered FDG dose.

The aim of this work was to define optimal energy windows for 124I small animal imaging with the Inveon PET system (Siemens Medical Solutions USA Inc., Knoxville, TN, USA), based on the noise equivalent count rate [NECR].

All data was automatically analysed using Matlab to estimate the noise equivalent count rate.

One study has compared the noise equivalent count density to visual IQ, showing that both are positively related.
