To minimize any chance of this happening an electronic device was invented that automatically detected even a single turn fault. As the years went by, many manufacturers either adopted impulse testing as a routine test, as an audit test, or could at least perform impulse tests when specified....
Our classifier is pretrained on 2,668 scans from a public dataset and 1,149 subjects with longitudinal chest CTs, billing codes, medications, and laboratory tests from EHRs of our home institution. Evaluation on 227 subjects with challenging SPNs revealed a significant AUC improvement over a ...
