Advanced X-ray and CT Imaging @ Stanford
The Wang Group develops advanced x-ray and CT imaging systems and methods. We are a part of the Radiological Sciences Laboratory (RSL) division of the Department of Radiology. We are located in the Lucas Center for Imaging and have research labs in the Grant Building and 3155 Porter Drive.
Our group's interests revolve around the following areas:
- Artificial intelligence / machine learning / deep learning for medical imaging, including CT acquisition, reconstruction, and image processing
- Photon counting CT, for clinical and research applications
- Dual energy, including dual-layer flat-panel detectors
- Novel systems and methods for x-ray and CT imaging
- Radiation transport methods for x-ray imaging and radiation dose
Our Labs
Photon Counting CT Lab
Our prototype PCCT scanner, in collaboration with GE HealthCare, is dedicated to human subjects research to investigate pathology- and disease-specific advantages that can be realized through photon counting CT, as well as technical research to evaluate image reconstruction techniques and fully utilize the high spatial and spectral resolution, in applications such as novel biomarkers for knee health.
Zeego Lab
Dr. Wang is also the Director of the Zeego Lab, which is a research CT system that can be used for phantom and animal studies. The Zeego is a highly flexible and powerful imaging tool due to its robotic C-arm, and is particularly well suited for image-guided interventions.
Tabletop Cone-Beam CT Lab
Our tabletop system can be configured to different geometries and consists of an x-ray tube, rotating stage, and flat panel x-ray detector. It can conduct precise experiments under highly controlled conditions and can prototype novel imaging technologies, such as our prototype dual-layer flat-panel detector. The system is also used as a teaching lab for biomedical instrumentation courses.
