AME - Biomedical Applications of Spectral Photon Counting CT

X-ray computed tomography (CT) allows scientists and clinicians to non-invasively visualize deep tissue structures within the human body in three-dimensions and at high spatial resolution. However, conventional CT is generally limited to anatomic imaging rather than molecular or functional imaging due to limitations in spectral resolution and soft tissue contrast. Spectral photon-counting computed tomography (PCCT) enables multi-energy X-ray imaging due to advanced, energy-discriminating photon-counting detectors. Material decomposition algorithms combined with spectral PCCT image acquisition transform CT into an anatomical and molecular imaging modality. Students will investigate the transformative imaging capabilities spectral PCCT in high-impact applications that are currently impossible or severely limited with current diagnostic imaging modalities.
