Tomosynthesis Imaging Symposium 2009:

Frontiers in Research and Clinical Applications

Apr 30 - May 2, 2009
Duke University, Durham, North Carolina, USA

Sponsors: Carl E. Ravin Advanced Imaging Laboratories,
GE Healthcare, Hologic, and Siemens Healthcare.
Co-chairs: Joseph Y. Lo and James T. Dobbins III

Updated: July 24 2009.


This conference has now concluded successfully. We were pleased to have hosted over 80 registered attendees from 8 different countries. We enjoyed a wonderful atmosphere of collegiality and earnest, open exchange of ideas, not to mention some really fantastic food!

We will maintain this website to distribute further information relevant to the conference such as the white paper discussion (see below), as well as for planning of future conferences.


Tomosynthesis is a form of limited-angle computed tomography that is receiving considerable interest from researchers and clinicians alike. Tomosynthesis can be used in a wide range of clinical applications, including diagnostic imaging (such as breast, chest, abdominal, orthopedic, and dental) as well as radiation therapy (IMRT and IGRT). Recent and pending US and EU approval of commercial tomosynthesis devices highlights the importance of this multi-disciplinary gathering where scientists and clinicians can discuss current work and exchange ideas about future directions.

Focus Areas:

  • X-ray source & detector technology
  • Acquisition geometry
  • Radiographic technique
  • Reconstruction algorithms
  • Visualization and display strategies
  • Computer-aided detection / diagnosis
  • Contrast-enhanced dual-energy
  • Phantom development
  • Image quality and dose
  • Quantitative analysis / density assessment
  • QC and acceptance testing
  • Multi-modality fusion
  • Clinical applications in radiology, incl. breast, chest, abdominal, orthopedic
  • Clinical applications in radiation therapy, incl. IMRT and IGRT
  • Clinical trial design
  • Clinical utilization strategies


The meeting was co-chaired by James Dobbins III Ph.D. and Joseph Lo Ph.D. of the Carl E. Ravin Advanced Imaging Laboratories of the Department of Radiology at Duke University Medical Center. Dr. Dobbins is the director of Duke's Medical Physics Graduate Program, and has collaborated closely with GE Healthcare during their development of the VolumeRAD tomosynthesis imaging system, which is now commercially available throughout the world. Dr. Lo is collaborating with Siemens Healthcare to investigate a breast tomosynthesis system and is principal investigator of studies sponsored by NIH and Siemens.

White Paper Initiative:

At the conclusion of this symposium, we devoted a session toward a group discussion on what lies ahead in tomosynthesis. All conference participants were invited to contribute their ideas toward the formulation of a white paper. Representing our community voice, this document may serve to facilitate communication with funding agencies as well as to influence research and clinical implementations of tomosynthesis in the future.

If you missed the conference, here is an unedited audio podcast (69 minute MP3 file, 8.8 MB). We are in the process of preparing some notes for sharing with the community, in preparation for the drafting of the white paper.


Conference sessions were held at Duke University. The campus is located in the Research Triangle of North Carolina, known for its mild climate, natural beauty, and vibrant cultural opportunities. The university is conveniently accessed from Raleigh-Durham International Airport (RDU) and the I-85 and I-40 interstate highways.
