Qiang Li
Adjunct Associate Professor in the Department of Radiology

Dr. Qiang Li's research interests include the development and evaluation of computer-aided diagnostic systems for lung cancer and interstitial lung disease in chest radiography and thracic CT, brain tumor in MRI, and intracranial aneurysm in MR angiography. He and his colleagues developed selective filter for enhancement of lesions and suppression of normal structures in 2D and 3D images, 3D algorithm for accurate segmentation of lung cancer and brain tumor using a spiral-scanning technique, automated rule-based classifier with high performance and minimized over-training effect, temporal subtraction of sequential images for enhancement of interval changes of lesions in chest radiography and whole-body bone scan, and contralateral subtraction for enhancement of asymmetric lesions in chest radiography. He also conducted a series of quality researches in the evaluation of CAD systems, including development of methods for reducing bias and variance in the estimated performance, development of guidelines for selecting appropriate evaluation methods in typical situations, and development of methods to improve CAD's generalizability for new cases.
