Clinical Decision Support System (CDSS) and self-learning tool for radiologists for Lung CT using Content Based Image Retrieval (CBIR).
We aim to design an automated system to detect and classify lung nodules in thoracic CT images with an objective to create a Clinical Decision Support System (CDSS) that could help radiologists in diagnosing lung nodules faster and with better accuracy. Also, this system can act as a self-learning tool for budding radiologist.

Pulmonary nodules are a potential manifestation of lung cancer, and its early detection can significantly enhance the survival rate of patients. Hundreds of images in thoracic CT scan makes nodule detection a very tiring process for the radiologists. Therefore, a CDSS system can be used to assist radiologists in detecting and diagnosing the lung nodules.

On getting an image, the system will try to detect a nodule and classify it according to the confidence index generated on the basis of similar nodule cases retrieved using Content Based Image Retrieval (CBIR).

1) To develop algorithms based on both shallow and deep learning techniques to accurately detect and classify thoracic nodules.
2) To develop a technique to automatically segment nodules in real-time.
3) To develop a Content Based Image Retrieval (CBIR) mechanism in order to classify nodules on the bases of past cases.
