Figures 2(a)–2(d) show a comparison of the equivalent WF images obtained by superimposing all frames from the acquired sequence and the DOLI images rendered by superimposing the localized position of the droplets.

WF images of the microfluidic chip were captured by the SWIR camera with 100 to 220 ms exposure time depending on the SNR of the images [Fig. U. A continuous-wave laser diode was employed for excitation of the sample. Fig. Biomed. A combination of images from two (or several) cameras with different orientations with respect to the sample may alternatively be used for three-dimensional imaging. Experiments performed in tissue mimicking phantoms indicate that high-resolution detection of fluorescent particles can be preserved over 4 mm depth range, while in vivo microangiography of murine cerebral vasculature can be accomplished through intact scalp and skull. We have engineered F4L5.13, a tetravalent antibody, designed to induce FZD4 and LRP5 proximity in order to activate downstream βcatenin signaling. [CrossRef].

Other diffusion-based optical imaging techniques, such as fluorescent molecular tomography [52], could potentially benefit from the newly introduced approach by boosting the resolution and accuracy of targeted fluorescent agent reconstructions for deep-tissue molecular imaging applications.

If you click on the wrong part of the histogram, you can find the bad measurement in the Results window, highlight it, go to Edit→cut and remove the bad entry. Here we introduce diffuse optical localization imaging (DOLI) to enable super-resolution deep-tissue fluorescence microscopy beyond the limits imposed by light diffusion. (a) WF image of fluorescent dye perfusion through the murine cerebrovascular system after scalp removal.

As previously shown in the phantom experiments, the size of the image spots corresponding to circulating droplets is strongly influenced by the scattering properties of tissue and the depth of field (DOF) of the camera lens, which can be exploited for discriminating structures located at different depths.
