the screenstreamer (239.194.200.200/1234) (but it has many powerpoint transition

<DIV>Speaker: Robert R. Meyer, Computer Sciences Department, University of
Wisconsin-Madison<BR><BR>Organised by: REDEGRID.<BR><BR>*
Abstract:<BR><BR>Radiotherapy is an important component of treatment for about
40% of cancer patients. In current clinical practice, expert judgment plays an
important role in determining the parameters of the increasingly complex
treatment plans needed to deliver emerging therapies such as IMRT (Intensity
Modulated Radiation Therapy), IMAT (Intensity Modulated Arc Therapy), and
Tomotherapy. <BR>For example, commercial radiation treatment planning systems
generally require a set of beam angles as part of the user input to the planning
<BR>process. While expert judgment may produce good solutions to these complex
problems, optimization techniques implemented on advanced computing platforms
offer the ability to automate the evaluation of huge numbers of potential beam
and couch angle sets. By thus automating the determination of good angle sets
and presenting the results to the treatment planner along with a comparison of
the relative effectiveness of simpler plans such as equally-spaced beams,
important insights may be obtained into effective <BR>treatment planning
alternatives. This presentation will consider several areas of radiation
treatment planning (RTP) in which advanced computing on clusters,
supercomputers, or the "grid" can significantly advance the <BR>state-of-the-art
and therefore the quality of radiation treatments delivered to
patients. These RTP research areas include data generation <BR>(which requires
the determination of radiation doses delivered from thousands of positions into
thousands of voxels), beam/couch angle selection, dose optimization, and
intensity map segmentation (to determine the final set of radiation delivery
parameters). We also discuss the potential that advanced computing and
cyberinfrastructure offer to the radiation treatment planner for a paradigm
shift from the current sequential "plan/review/modify" process to a faster and
more effective parallel "multi-plan/compare/select" framework.<BR><BR>*
Biosketch:<BR><BR>Robert R. Meyer received a B.S. in Mathematics from Caltech
and an M.S. and a Ph.D. in Computer Sciences from the University of
Wisconsin-Madison. After several years as a researcher with Shell Oil, he moved
to academia and is currently Professor of Computer Sciences at the University of
Wisconsin-Madison, where he has been on the faculty since 1973. He
has co-edited six volumes of optimization conference proceedings and written
more than 80 papers dealing with nonlinear network optimization, parallel
<BR>algorithms for large-scale optimization, genetic algorithms, theory and
applications of discrete optimization, machine learning, and radiation
<BR>treatment planning in brachytherapy and teletherapy. His current research,
funded by the National Science Foundation, focuses on optimization methods,
advanced computing based on the Condor system, and cyberinfrastructure
<BR>utilization for radiation treatment planning.<BR><BR><BR>Venue:
