Research Interests
Dr. McNitt-Gray’s research interests involve investigations into X-ray computed tomography (CT) imaging with the goal of maximizing the information that can be extracted from the resulting image data. These activities include research into:
The physics of CT image acquisition including estimating radiation dose and assessing image quality
Image processing techniques to analyze and extract information from the CT image data, including computer aided detection and diagnosis (CAD)
Monte Carlo Based Patient Radiation Dose from CT
The long-term goal of this research is to create methods to an accurately estimate radiation dose to patients undergoing CT scanning. We propose a Monte Carlo-based modeling approach that overcomes the limitations of previous methods by accurately modeling MultiDetector CT source characteristics, the effects of different scan parameters and realistic patient models of different sizes, ages and genders. This project represents collaboration between investigators at the David Geffen School of Medicine at UCLA, the University of Texas MD Anderson Cancer Center in Houston, Tx and the Mayo Clinic, Rochester, MN
