Point Scanning Confocal is a patented technology designed and developed by Optiscan over many years and is responsible for the stunning full field of view image capture delivered by FIVE2 (ViewnVivo).
Embedded within the tip of the miniaturized probe is a complex mechanical scanner, comprising a pair of lenses that focus the laser at the exact depth required. The laser is delivered, and the returning light is captured through a single optical fibre that is moved across the field of view (scanning) to capture the entire image. The system controls the speed at which the optical fibre scans, and can be adjusted accordingly along with the power of the laser, to provide optimal results.
The following image is a comparison of legacy Bundle Fibre technology (left) and Optiscan Point Scanning Technology (right). Image set A presents a sample scan at full screen resolution. Image set B represents a focal area (point of interest) of the sample image, and Image set C is the zoomed view of this focal area. As you can see, legacy Bundle Fibre technology does not offer a level of clarity and detail any where close to Point Scanning Technology.
Remember, you cannot view or create what is missing from the original raw image. Missing information cannot be created or interpolated through image processing. Don’t settle for half the picture – use FIVE2 (ViewnVivo)!
