Development of CADx for pulmonary nodules
Optellum is a new UK-based company whose vision is to enable cancer to be diagnosed earlier and with more confidence. Our team consists of award-winning machine learning and imaging experts who met at Oxford (UK), and we have a track record of bringing innovation into clinical use. Our PI, who joined Optellum in 2016, was previously the technical lead on the project that won the NIH's 2015 LUNGx challenge, and has worked extensively with NLST data previously.
We are currently developing deep learning solutions for the characterisation and stratification of pulmonary nodules in CT, and our performance to date matches that seen in state-of-the-art systems. We currently have access to the Oxford Lung Nodule database, which is composed primarily of nodules from screening and oncology follow-up, and we now seek access to the NLST data to complement this in our ongoing research and development work.
1) Validate Optellum's current pulmonary nodule software on screening data.
2) Develop and test new models for pulmonary nodule analysis and stratification on screening data.
3) Improve Optellum's robustness to variations in scanner manufacturer, kernel type, patient geographic location etc, since differences in these factors are well-represented in the NLST data.
