Summary of the technology
Currently, cytologists are needed to examine smear samples under a microscope to visually assess the shape, size and stain pattern and determine if abnormal cells are present which could indicate cervical cancer. Alternatively, automated image analysis is used to determine nuclear density but cytologists are still needed to determine the presence of abnormal cells. The current processes are prone to human error and misdiagnosis can be up to 60%. They are also time consuming and costly.Sample user interface for spectral acquisition and classification.
Researchers at DIT have invented an easy to use, low cost, automated analyser that uses a pre-defined library of known cell signatures and a proprietary classification algorithm to detect abnormal cells with an accuracy of 99%. The analyser can be used with a regular microscope, an image analyser or as a point-of-care system with results displayed using an intuitive user interface. The image and the classification can be saved in digital format, stored in a national database, and sent to the medical team or experts worldwide
Description of the technology
Dublin Institute of Technology (DIT) is seeking companies to license an automated diagnostic system for screening cervical cancer that has high specificity and high sensitivity. This low cost cervical cancer analyser uses algorithms to analyse Raman spectra of sample cells and classifies the samples by comparison with a pre-defined sample database. It can be used with conventional microscopes or more advanced image analysers and can also be used as a point-of-care system. The system is an improvement on current cervical cancer screening processes given more automation and less reliance on human subjectivity. As the analyser is small, fast and works with conventional microscopes, it is suitable for clinical applications.

Main advantages of its use
- Easy to use – no specialist training or experience in spectroscopy is required to operate the system and the system works with a common microscope.
- Fast – with low resolution scanning and less subjective interpretation of the results, the screening rate is faster than the 5-8 minutes per conventional smear tests.
- High sensitivity – greater than 99% accuracy in the classification of abnormal cells, improving cancer detection and reducing false negatives.
- High specificity – greater than 99% accuracy in the classification of normal cells reducing false positives.
- Less human error – as definite negatives can be eliminated automatically, more time can be given to the analysis of possible positives.
- Low cost : the technique uses a low cost, low resolution Raman spectroscope and operating costs are low as no
- Network friendly – digital classification data can be stored in databases and remotely sent to experts for consultation.
- Cell analysis applications e.g. most other cancers, forensics and food contamination
- The cervical cancer analyser can be used:• with a regular microscope• with an image analyser• or as a point-of-care system
