Research Interests

The Advanced Theranostics and 3-D Imaging Laboratory (AT3D Lab) is a research and teaching laboratory in Tsinghua University. The laboratory was founded by Professor Hongen Liao in 2012, as supported by National Recruitment Program of Global Experts in China. The Lab includes three faculty members, 12 graduate students, and eight undergraduate students. The AT3D Lab and its previous teams have been involved in the development of image-guided surgery, three-dimensional (3D) medical images, medical robotics and fusion of these techniques for minimally invasive precision diagnosis and therapy for about 20 years.

We have developed an autostereoscopic medical image named Integral Videography and first implemented it in an image overlay system for surgical navigation, and succeeded in creating an image display that appears to have three dimensionality even when viewed from a distance, with an image depth of more than five meters in front of the display. These results have also been reported by numerous international media including USA, UK, Germany, Russia, and Japan. The developed 3D display devices have been demonstrated at more than 10 exhibitions and museums, including Hannover International Exposition, National Museum of Emerging Science and Innovation in Japan, and China Science and Technology Museum.

We have published more than 220 peer-reviewed articles and proceedings papers including publications in MedIA, Nature Photonics, and IEEE Transactions, more than 20 book chapters and survey reports, 36 patents, as well as over 290 abstracts and numerous invited lectures.

Our research interests include the development of related autostereoscopic medical imaging technique and its implementation in an image-overlay system for surgical navigation. This technique has also been extended to other 3D areas, such as long-viewing-distance 3D visualization and a high-quality autostereoscopic display. Our current research projects also include the development of high-precision, minimally invasive interventional surgical devices and medical robotics, novel medical autostereoscopic image, as well as integrated medical images for minimally invasive precision diagnosis and therapy.
