WE ARE GRAYLIGHT IMAGING – YOUR PARTNER IN
Measurements in medical imaging
We’ve created and continue to develop algorithms for extracting valuable data from medical images various modalities.
Take advantage of our know-how and capabilities to create customized solutions that will give you the quantitative data you need.
LEARN MORE ABOUT OUR SOLUTIONS FOR AUTOMATED MEDICAL IMAGE SEGMENTATION
Medical image segmentation with machine learning
Our solutions based on machine learning automatise the segmentation process. The models we worked contour organs and detect as well as localize structures within organs on various types of examinations.
Segmentation based on our deep learning method:
- is precise and fast, provides repeatable results as well as enables extraction of measurable features of anatomical structures and lesions
- has achieved an accuracy of more than 90% (Sørensen-Dice coefficient of roughly 0.9) [1]
- is characterized by effectiveness proven in many prestigious global AI challenges (such as BraTS and FeTS)
- can be embedded into existing solutions
OUR CAPABILITIES TO CREATE CUSTOM SOLUTIONS
Extraction and measurement of quantitive data from medical images
Bespoke algorithms we’ve been developing for our clients are designed to meet particular needs and requirements. They are able to measure and analyze as well as provide valuable quantitative data. This technology can be used to detect any lesion, for any internal anatomical structure of a single patient.
Detection of a single lesion on a scan, as well as multiple parts of a larger lesion
Evaluation of measurable lesion according to a predefined requirements
Lesions detection in time – detection of new lesions on a follow up scan
Evaluation of patient response to treatment also outside standard criteria
SELECTED WORK
Proven experience
Automated RANO and RECIST+
We created and applied fully automated algorithms for precise and comprehensive patient response measurements using RANO and RECIST criteria (automated RANO and automated RECIST) to real-world data. Furthermore, our technology is capable of much more than what the guidelines suggest.
Case study of automated RANO calculation
- Volumetric measurements of predefined regions or subregions
- Repeatability and objectivity of results
- Integration with the segmentation algorithm, as all takes place in one step
- Higher bidimensional measurement than those reported by most human readers [2]
