The Third International Workshop

on Computational Phantoms for Radiation Protection, Imaging and Radiotherapy

Tsinghua University, Beijing, China

August 8 and 9, 2011


T
he “Handbook o
f Anatomical Models for Radiation Dosimetry
” published in 2009 was a
major effort by 64 authors from 13 countries to document many phantoms developed in the past
60 years. Although the book chapters covered only selected work, the literature survey
indicated that the total number of computational
phantoms had surpassed 100 by 2009, owing
to extremely strong interests from the research community in the past decade.



The momentum has continued and many new projects are creating phantoms that
consider anatomical variations associated with gender, age
, pregnancy, obesity, organ motion
and posture. Application of these phantoms to ionizing radiation has diversified, covering a
broad range of radiation protection, medical imaging and radiation treatment. Various Monte
Carlo simulation and visualization
techniques have been adopted and developed. Over the
years, the non
-
ionizing radiation community has also developed a large number of phantoms for
assessing risk associated with exposure to different types of electromagnetic waves. Despite
the similarity

in research methodologies, these two groups of researchers have not had the
opportunity to closely interact and exchange. With peta
-

and exa
-
scale high
-
performance
computers becoming available this decade, there is no doubt that the development and
app
lication of computational phantoms will continue to evolve in rapid and radical ways. Two
computational phantom related workshops were held at
NRPB and at ORNL,

both playing a
historical role in guiding future research direction. It is clear that the pa
ce and complexity of
today’s computational phantom research require us to meet more frequently than we did in the
past.

This Third International Workshop on Computational Phantoms for Radiation Protection,
Imaging and Radiotherapy is organized for the rese
arch community to discuss current issues
and to develop a roadmap for the next 10 years.


The scope of this year’s workshop covers four main topics:

1.

The Chinese Visible Human Project:


Color cross sectional data at 0.1mm
-
resolution
containing fine anatomic
al features not available in the past



2.

Ionizing Radiation Protection:


“ICRP Computational Phantoms” ; Intercomparison with
other phantoms; Dose reconstruction for nuclear accidents (Fukushima Daiichi nuclear
power plants)

3.

Non
-
ionizing Radiation Protecti
on: International recommendations on safety of humans
in electromagnetic fields; Phantoms for the non
-
ionizing radiation community.



4.

Tools and Applications.


Monte Carlo calculations in NURBS/meshes; deformable
bioassay lung/breast

phantoms; CAD phantoms;

4D time
-
dependent respiratory/cardiac
phantoms for imaging/therapy.
