Enhance the accuracy of your scanners and the digital images they produce by colour calibrating them to a unique industry standard ICC profile – bring uniformity to images product range-to-product range, scanner-to-scanner
Sierra colour calibration slides
The slide is used to measure the spectral ‘ground-truth’ of stained colour and to measure the digital interpretation of this by a WSI device.
The Sierra slide utilises a biopolymer identified by FFEI that mimics the behaviour of normal tissue when histologically stained. This unique feature allows the creation of a set of coloured samples that have spectral transmittance that is near identical to stained tissue samples. By using different stains at different intensities, it is possible to produce the most commonly encountered colour intensities in histology and cytology.
Bespoke integration of Sierra calibration data to assist AI database interrogation.
Different WSI systems and software applications require unique database architectures and bespoke file integration mechanisms. Our skilled software engineers are able to advise or assist with creating the optimum methodology and software for combining Sierra ICC profiles with the desired WSI output or precise database input for uniform and correct interrogation by AI and pathologist alike.
ICC colour profile
Every slide enables a series of unique and quality controlled ICC profiles to be created from multiple scanners.
The ICC profile is automatically generated by our software in response to the Sierra slide results. This profile provides corrections to the digital images generated by the scanner so that they represent ‘ground truth’ colour. This also means any images generated by any scanner that has undergone Sierra colour calibration will be uniform in colour.
Bespoke client portal for automating ICC profile generation.
FFEI have the ability to fulfill the specific needs of Sierra customers – we provide standalone software for live or transient analysis on our secure servers, to accommodate variation in network access, whilst offering the option to create a bespoke client portal for more extensive and detailed management of ICC profiles.
DEPLOYMENT OPPORTUNITIES FOR SIERRA COLOUR CALIBRATION
Quite often colour calibration is discussed as an end of process activity. In reality colour calibration can be performed at many stages
of a WSI production and lifecycle.
Manufacturers can colour calibrate their installed base as part of routine software upgrades.
WSI device manufacturers can test and calibrate every scanner at the point of production.
Every lab armed with it’s own calibration slide and software can test and calibrate their scanners – checking them on a regular basis to ensure accuracy and uniformity.
Field service engineers
Engineers have the ability to routinely ensure their entire scanner portfolio remains in colour calibrated alignment, and remains so after maintenance of the image path.
Calibrate scanners from any manufacturer being used to train AI software or used by clients, to ensure colour uniformity and fidelity – “good data in = good data out”.
Manage a whole lab without being restricted to the type of device that can be installed due to colour difference.
