Olympus has released the latest
version of its virtual slide (VS) product range, the VS120. The system can
rapidly scan a slide in less than two minutes, creating a digital ‘virtual
slide' that is an exact copy of the original. This is easily created and navigated
using an intuitive graphical interface. The new unit provides semi-automatic
and manual focusing modes for working with challenging samples, enhanced image
clarity using the new Sample Detection Mask for automatic slide scanning, and
increased optimisation of user workflow. With the ability to digitise and share
entire slide collections across the laboratory, classroom, or globe, the VS120
is perfect for use in research, pathology and teaching.
The Olympus VS120 provides an array of
new user benefits that simplify and enhance digital slide capture, storage and
analysis. The system is extremely fast, scanning a 15 x 15mm area using a 20x
objective lens with a pixel resolution of 0.345µm in around 90 seconds, while
sample detail is enhanced and preserved via the high quality Olympus UIS2
optics and custom camera algorithms. Using a threshold-based method to remove
small particles, the new Sample Detection Mask improves image quality by
maintaining accurate focus when using automatic settings. In addition, the
Expert and Virtual Z scan modes offer semi-automatic or manual focus settings,
providing more flexibility. When analysing virtual slides with multiple
Z-stacks, it is possible to extract a single Z-stack of choice for further
study, while the new Freehand Measurement tool can be used to generate
quantifiable data from each image. To facilitate high-throughput scale-up,
Olympus provides the optional VS120-L5, which can scan up to five slides
automatically. For larger collections, the VS120-L100 provides ‘walk away'
scanning of up to 100 slides, while an inbuilt barcode scanner ensures that all
slides are accurately tracked and catalogued.
Using the VS120, images can be captured regardless of the
illumination technique, including bright-field, phase-contrast and
multi-channel fluorescence via the additional fluorescence extension module. In
addition, the new high resolution camera has three predefined brightfield
settings that simplify and optimise the scanning of normal, dark or faintly
stained samples. The virtual slides created can be navigated digitally in
real-time as if the user were controlling a microscope, without the need for an
instrument or even the sample. All images are ICC profile corrected to ensure
perfect colour reproduction, and the system is compatible with standard and
double sized slides for maximum accuracy and flexibility. Virtual microscopy
enables the information from one slide to be shared simultaneously across the
world, via the simple upload interface provided by the secure Net Image Server
SQL networking system. This makes the VS120 perfect for teleconsultation during
disease diagnosis, global research collaboration, the archiving of slide
materials and for sharing data with the classroom when teaching.
