We are currently undertaking research in several innovative projects
in the field
of diagnostic computed tomography (CT). A brief description of each
is given below.
Current Projects & Activities
Z-Scan CT [Project Link]
We are investigating a new scanning principle (Z-scan) which will
provide simultaneously high spatial resolution (0.5mm) and temporal
resolution (15 msec) cardiac images.
Interventional Real-time Platform [Project Link]
We are investigating a new
interventional platform by integrating novel tomosynthetic perfusion imaging
and cone-beam CT imaging onto a C-arm system. This system will provide high
quality images of the vasculature to guide the interventions and provide perfusion
imaging method to evaluate the efficacy of stroke interventional
procedures without moving the patient to another scanner.
Cone-beam Reconstruction
We are investigating novel image reconstruction methods for cone-beam
scanning geometries including Helical/Spiral CT, C-arm based scanning
trajectories, Z-scan CT scanning trajectories,
and tomosynthetic image reconstruction methods.
