Diagnostic Medical Physics Laboratory

Expertise within the Diagnostic Medical Physics Laboratory includes tomographic image reconstruction, radiation dosimetry, physical and perceptual evaluation of image quality, and advanced computational methods in diagnostic imaging.

Our current area of focus is on creating and optimizing new methods of imaging the breast that take advantage of the introduction of digital detectors for mammography. These include breast tomosynthesis and dedicated breast CT, for which the laboratory is engaged in developing novel reconstruction algorithms, optimizing image acquisition and processing methods, and characterizing the radiation dose involved in these modalities. In addition, novel radiation dose metrics for personalized dosimetry in breast imaging are being developed.
