Huygens Confocal Deconvolution Software

Specially designed for single point-scanning Confocal Microscopes

Raw Confocal
Huygens Deconvolved
Single point-scanning Confocal Microscope images can be successfully deconvolved within the Huygens Software. This offers significant improvement in object resolution in x, y and z as well as an increase in object signal and correction of noise. As a result, images will be easier to segment for optimal visualization and analysis. The gain in signal and correction of noise also allow you to image faster, causing less phototoxicity and bleaching. Huygens offers state-of-the art implementations of the Classic Maximum Likelihood Estimation (CMLE) and the Good's roughness Maximum Likelihood Estimation (GMLE) algorithms, which work very fast and efficiently on noisy image data.

Faster imaging

A key limitation of confocal imaging is the long acquisition time. This time can be strongly decreased when using Huygens Deconvolution after image acquisition. Huygens Deconvolution decreases noise while increasing the object signal. Clear images can therefore be recovered even when the raw data has a low signal-to-noise ratio (SNR). Since a low signal is already sufficient, the exposure time can be decreased. It then takes less time to image the entire sample.

Microscopy images are aberrated with respect to the objects under the microscope. These aberrations are not constant throughout the entire image: typically, the image quality gets progressively worse as you move deeper within the sample. This is due to Spherical Aberrations caused by a mismatch between the refractive indices of the sample and of the lens medium. Huygens Deconvolution accurately calculates the function describing the aberrations in the image, the so-called Point Spread Function (PSF), in a depth-dependent manner. It then uses this depth-dependent PSF to achieve consistant restoration quality over the entire depth range.

Image description
Theoretical PSFs calculated by Huygens based on the distance to the coverslip. Huygens Deconvolution is performed in a depth-dependent manner to ensure consistent restoration quality throughout the image. Distances between PSFs were decreased for visualization purposes.

The best deconvolution results can be achieved by using a measured PSF extracted with the Huygens PSF Distiller. After deconvolution, images can be used for reliable image analysis, for example colocalization analysis.
