Research Interests:
My primary research interests are in the development and applicatin of digital imaging techniques for cancer detection and evaluation. Applicatins to chest and breast imaging are the main focuses. The current research activities are focused on digital chest and mammographic imaging techniques using flat-panel (FP) detector, charge-coupled-device (CCD) and computed radiography (CR). I am also interested in quantitative image quality measurement.
A tutorial would provide student experience in the area of digital radiography using state-of-art digital detector techniques. The student will have opportunity to learn operating digital imaging systems, acquiring digital images, transferring and retrieving image data. The student will also have opportunity to practice image quality metrics measurement such as MTF, NPS, and DQE.
