Machine learning-based identification and classification of pulmonary nodules

The current clinical practice performed in the diagnosis of lung cancer is a thorough yet lengthy procedure featuring X-ray scans, CT scans, and depending on the initial findings - lung biopsies and other kinds of imaging tests. However, these tests tend to be highly invasive and costly. An alternat...
