The phrase "average intensity per" is correct and usable in written English.
It can be used in contexts where you are discussing measurements or calculations that involve intensity distributed over a certain unit, such as time or area.
Example: "The average intensity per square meter of the light source was measured to determine its effectiveness in the room."
Alternatives: "mean intensity for" or "typical intensity per".
A 'super-spot' for each group is obtained by aligning all spots of a group with the brightest pixel at the center of a 25 × 25 × 13 voxel region of interest and by taking the average intensity per voxel in that region over all spots.
The procedure does not assume low-frequency global effects and is based on the assumption that the global signal (the time course of the average intensity per volume) is replicated in the same pattern throughout the brain, although not necessarily at the same magnitude.
When corrected, the deviation in average intensity per nucleus was within 10%, suggesting that the protocol adequately corrects for non-uniformities.
Then the average intensity per segment is calculated, as well as the standard deviation.
The average intensity per pixel was measured for 10 random fields of view for each sample, using ImageJ.
Fluorescent images were acquired and analyzed by measuring the average intensity per cell from multiple images after background subtraction using IPLAB software (BD Biosciences, San Jose, CA, USA).
Quantitation of the EB red fluorescence emission, measured as the intensity per area unit (mean gray value: averaged intensity per pixel), was done in the whole striatum and parietal cortex of vehicle- and GA-injected animals by using the Image J software (NIH, USA).
Average ± SEM of normalized mean intensity per cell (n=11 cells, Bem1; n=14 cells, Cdc24).
Data are expressed as average intensity (integrated intensity per area of region of interest) from one artery per rat for six rats in each group and were gathered using Metamorph software (version 7.0; Molecular Devices, Sunnyvale, CA).
By averaging mass spectra of 10 randomly selected plugs of verapamil water solution from the same experiment, we calculated the average intensity value per plug to be 435 ± 45 counts, indicating a 10% plug-to-plug variation.
The respective averaged intensities per SNP position are consequently pseudo-replicates of different sub-ensembles of probes referring to the same interaction mode, namely perfectly-matched (PM-GG) or single-mismatched (MM-GG) probe/target duplexes (see the schematic drawings in panel a of Figure 2).
