Image deconvolution algorithms reverse out-of-focus fluorescent blurring in widefield microscopy
Die Weitwinkelmikroskopie ist ein leistungsstarkes Werkzeug, das zur Erforschung zellulärer und molekularer Prozesse angewendet wurde, die an der Übertragung von Zellsignalen beteiligt sind. Although fluorescent blurring from out-of-focus light is an innate result from all widefield microscopes, image deconvolution algorithms can reverse this out-of-focus light artifact.
The Digital Confocal Option is a 2D real-time deconvolution technology that helps to restore a cellular image’s resolution and contrast by mathematical deblurring of the image through reversal of the point spread function. As a result, images and fine detail become sharper while maintaining quantitative information.
Significantly increase throughput and assay quality
The Digital Confocal Option* enhances contrast of images during acquisition, allowing you to decrease exposure time more than two fold and increase throughput while maintaining assay quality. Alternatively, assays with low Z’-factors can be improved more than 25%. This intelligent analysis enables researchers to increase their throughput, allowing acquisition and analysis of more than 10 million cells per hour.
The speed and convenience offered by the new module delivers a real advantage for scientists as it provides the user with real-time deconvolution without the need to post-process the images. For researchers working in high-content screening, significant resources are dedicated to screening millions of samples for rare new drug or gene therapy candidates.
Digital Confocal Option is designed for the ImageXpress Pico and ImageXpress Micro system solutions.
Designed for the ImageXpress Pico System and CellReporterXpress Image Acquisition and Analysis Software
Erzielen Sie eine signifikante Erhöhung der Auflösung und der Qualität von Assays – mit der „Digital Confocal“ 2D Sofort-Dekonvolution. The Digital Confocal Option* restores light to its original point of origin, allowing you to decrease exposure time and improve statistical significance of your observations. Digital Confocal is seamlessly integrated into the ImageXpress Pico system's fluorescent image acquisition workflow allowing you to capture images with higher signal-to-noise data for more precise segmentation and analysis.

Designed for the ImageXpress Micro Systems and MetaXpress High Content Image Acquisition and Analysis Software
The new image deconvolution module delivers a real advantage for scientists working in high-content screening, where significant resource is dedicated to screening millions of samples for rare new drug or gene therapy candidates. The integration of ImageXpress Micro systems with the Digital Confocal Option for MetaXpress software provides unrivaled performance for ease-of-use, while providing high speed and quality images.
Digital Confocal Option enables robust image analysis
Images with Digital Confocal Option enabled during acquisition (bottom) show cell structures more clearly than without (top), enabling more robust image analysis.
Digital Confocal Option sharpens intensity peaks of fluorescent objects
Images of HEK 293 cells containing paraspeckles were acquired with the ImageXpress Micro XL System without (top) and with Digital Confocal Option (K value 0,063) (bottom). The histograms of a line scan through representative images shows how the Digital Confocal Option can sharpen the intensity peaks of the fluorescent objects. A more accurate count of the paraspeckles was achieved when analyzing the digital confocal images with the Granularity Application Module for MetaXpress software (right).

Assays requiring precise identification of sub-cellular structures or molecules within different compartments of the cell can benefit from the ability of on-the-fly image deconvolution to improve identification of the specific fluorescence signal against potentially high background caused by out-of-focus light. We utilized the ImageXpress Pico system and CellReporterXpress software to assess the translocation of NF-κB from the cytoplasm to the nucleus of HeLa cells upon treatment with TNF-α.
