Sentence examples for variance imaging from inspiring English sources

It is possible to maintain correlation across multiple rapidly acquired images in the human retina in vivo, as this is a prerequisite for phase variance imaging [ 41].

Recent advances in FDOCT technology have produced methods including optical microangiography [ 16], joint time-spectral OCT [ 17], speckle and phase variance imaging [ 18, 19], and power or variance Doppler techniques [ 4, 20] that enable non-invasive capillary level detection of the retinal vasculature.

A recent variant of SOFI called variance imaging for super-resolution (VISION) demonstrated a remarkable 80ms temporal resolution [ 20].

The capability of GPU based real time speckle variance imaging has in fact been recently demonstrated [ 26].

We address the limitation of speckle variance imaging and provide two different techniques to correct for bulk motion in the spinal cord.

While speckle variance imaging offers the combined advantage depth resolved imaging of microvascular networks without the limitation of sensitivity to the Doppler angle, bulk motion can limit the use of this technique.

Another type of calibration may have to be applied to eliminate variance between imaging devices of the same model.

Speckle variance (SV) imaging was also investigated in this part of the experiment, with a typical SV image displayed in Fig. 6.

In order to reduce variance between the two fluorescence imaging techniques it was necessary to utilize the same masks of the teeth.

In our experiments, we find that phase is not generally stable, and we instead compute the variance of the OCT amplitude, a method which was recently shown to give comparable results to phase variance methods for blood flow imaging [ 39].

For each task-specific ROI, the association between brain activation and NCD status was determined using an analysis of variance (ANOVA) model, after controlling for imaging site.
