^™Huygens Fuser

Align multiview Light Sheet images using interactive scenes and automated fine-tuning

Common in Light Sheet Fluorescence Microscopy (LSFM) is the acquistion of multiple (opposing or rotational) views, and fuse these to compensate for light absorption and scattering issues. Typically, interest points (e.g. beads) are included to facilitate this fusion process. Huygens Fuser does not require the use of beads. Instead, each view can be optimally positioned by shifting, rotating, and scaling it using the interactive scene. Advanced correlation algorithms then fine-tune the alignment. Real-time visual feedback during the alignment process gives you full control over the fusion!

Huygens versatile Fuser is extremely easy to use, suited for all multiview data with its additional expert fusion settings, includes deconvolution for all light sheet types, and offers CPU + GPU support for efficient computation.

Testimonials

I tested the lightsheet fusion with 8-view lightsheet stacks of a drosophila ovary. The fusion worked great! What was especially useful was that it did the registration and fusion without fiducial marker beads in the images. Dr. Benjamin Lopez, facility director NRI-MCDB Microscopy, University of California Santa Barbara, USA.

Deconvolution of lightsheet data is not a trivial task, and also fusion of multiviews is in my experience with other software packages a trial and error process. I was really amazed by the Fusion Wizard in Huygens that actually accomplishes both tasks fast and efficiently Dr. Marco Marcello, imaging manager Centre for Cell Imaging, University of Liverpool, UK.

Interactive interface with automated fine-tuning

The fusion process consists of two main parts: manual approximation followed by automatic optimization. In the interactive Fuser window, the user can approximately align the different views in an intuitive manner by zooming, shifting and rotating them on top of each other. Optional settings, including pixel weighting and cropping and sampling settings, allow for further customization of the fusion. After the manual approximation, the Fuser uses advanced correlation algorithms to fine-tune the alignment. Huygens' unique Light Sheet Deconvolution is integrated in the fusion pipeline, allowing for fusion based on fine image details and ensuring a high-quality final image.

All dimensions, all LSFM types

Huygens Fuser can be used to fuse images acquired with any type of Light Sheet microscope and from any imaging direction. In addition, the Fuser can process data from 2D to 5D (multi-channel 3D time series).

Light Sheet Deconvolution & Fusion in Huygens

The Huygens Fuser has the option to deconvolve and fuse Light Sheet images within one single workflow. Several different light sheet setups are supported, including but not limited to gaussian, high fill factor, scanning and lattice-based systems. By selecting parameter templates customized for your specific LSFM system, both the deconvolution and the fusion are easily and reproducibly executed. Huygens unique set of additional restoration options allow you to correct for additional imaging artefacts like hot&cold pixels, crosstalk (bleedthrough), chromatic aberration, and drift.

In some Light Sheet setups, the sample is moved horizontally across an obliquely oriented excitation beam. The resulting images are then skewed and should be stabilized before further processing. Light Sheet images can be deconvolved reliably with Huygens' specialized Light Sheet Deconvolution.
