Title
Pulmonary Nodule Detection in Lung CT Images using Deep Learning Networks

Summary
The project (ongoing for 1 year now) aims to develop a computer aided diagnostics (CAD) tool for the automatic detection of Pulmonary Nodules in Lung CT images. As is common in recent years, we are using Deep Learning to develop this model. We have internally a team of 4 researchers/developers that deal with: adapting existing leading edge DL models, improving them and using ensemble techniques to combine them, create tools for annotation of images so that Radiologists can annotate CT scans and give feedback on our model's output, a novel UI to accelerate the process of 'ruling out' false alarms by the Radiologist, and special modules for false alarm (blood vessel thickening) removal.
The project has so far operated on public open source datasets such as Luna16 and the Kaggle data set, as well as on data provided to us by Assuta Medical Center and Kupat Holim Meuhedet (an Israeli HMO). We also have a Radiologist consultant on our team for day to day annotation and feedback.
We wish to increase our dataset as we have seen clearly the results improve when we add more data and label/annotate it.

Aims

Using additional Lung CT images, improve the performance of the existing Deep Learning model to improve sensitivity/accuracy (percent of true positives) and dramatically reduce the amount of False Positives.
