Career Achievements

Most Impactful Work – Spiral Cone-beam CT

He pioneered the spiral cone-beam CT method in 1991. His work on spiral cone-beam CT solves "the long object problem" (longitudinal data truncation) and has a major impact on the CT field.  Defrise et al. wrote that “to solve the long-object problem, a first level of improvement with respect to the 2D filtered backprojection algorithms was obtained by backprojecting the data in 3D, along the actual measurement rays. The prototype of this approach is the algorithm of Wang et al.” La Riviere and Crawford wrote that “most commercial systems used approximate methods based on extending the Feldkamp–Davis–Kress reconstruction to helical cone-beam scanning trajectories initially formulated by Wang et al.” For this work, he was inducted to the National Academy of Inventors in 2019. He and his collaborators published many papers on spiral cone-beam CT, including  exact cone-beam reconstruction with a general trajectory, a quasi-exact triple-source cone-beam reconstruction, and more. Currently, there are ~200 million medical CT scans yearly with a majority in this scanning mode.

AI-empowered Breakthrough – Deep Tomographic Imaging

In 2016, he presented the first roadmap on deep tomographic imaging. With his collaborators he published a series of papers in this new area of image reconstruction, including major results on deep denoising, deep reconstruction, deep radiomics, and healthcare metaverse. With his coauthors, he published the first book on machine learning-based tomographic reconstruction in 2019 (IOP Top Download, more than 33,000 in 2020), and edited two special issues on this theme for IEEE Transactions on Medical Imaging. In partnership with General Electric, FDA and other leading institutions, his team develops deep imaging algorithms and systems for clinical and preclinical applications.

Other Innovations

He and his collaborators developed interior tomography to solve “the interior problem” (transverse data truncation), and omni-tomography (for spatiotemporal fusion of tomographic modalities, with  simultaneous CT-MRI as an example. Also, his team developed bioluminescence tomography for optical molecular imaging and spectrography for ultrafast and ultrafine tomography from polychromatic scattering data. He worked on axiomatic bibliometrics, with results reported in Nature, Science, and news media. Also, he developed the first undergraduate and graduate courses on deep medical imaging and distanced online testing technology.
