Kyoto Kagaku New Lineup

Multi-Energy CT Phantoms
For Quality Assurance and Research
OVERVIEW

Multi-Energy CT (MECT) or Dual Energy CT (DECT) is a new frontier of rapidly advancing medical imaging, andnow entering clinical practices in hospitals.
The technology enables material differentiation, elemental decomposition and material quantification.
Such features are expected to bring us better diagnosis, improved image quality, reduction of radiation
exposure, reduction of contrast agent volume and opens possibility of functional imaging.
Meanwhile, further studies are awaited in various field such as quality management of CT equipment, verificationof protocols, expansion of clinical application, to derive the maximum benefits from the technology.
Kyoto Kagaku supports researchers and clinicians with up-to-date innovative phantoms.

BACKGROUND
In many MECT/DECT studies, water phantoms have been used. However, using real water can impose considerable
work in preparation and handling. At the same time, using acrylic containers limits the design of phantoms.

Need to standardize
the examination

Want to test the protocols onsomething anthropomorphic

Preparation of phantoms
takes too much time

Have to conduct
quality test

Vital factor for Multi-Energy-CT Phantom "Water Equivalent Material"
About Water Equivalent Material (WEM)WEM has high equivalency to water in diagnostic
energy ranges(40-190KeV)
Co-developed with; Professor Ichikawa Katsuhiro,
Faculty of Health Sciences, Institute of Medical,
Pharmaceutical and Health Sciences,
Kanazawa University, Japan

Experiment
Place the material inserts on water tank
110 kV80 kVRods are not shownin the CT images!!

WEM
Nine rods of WEM are"invisible" under CT

conventional materials
Two rods of WEM
and for conventional
materials for phantoms

Supports iodine quantification and materialdecomposition: conventional material forradiotherapy phantom

Unlike conventional "water substitute" materials the Water
Equivalent Material maintain water equivalency under low
energy range. This feature support studies that involve
iodine quantification.

Save time and trouble for study and expand
possibilities
Save time, costs and efforts to design and produce custom
acrylic water phantoms.
Unlike water phantoms, phantoms with solid materials
reduce the troublesome process to change water andinside rods.

CONCLUSION
1. Kyoto Kagaku Multi-Energy CT phantoms may save time and cost of preparing custom
made phantoms for the researchers.
2. Water Equivalent Material(WEM), enable to create phantoms with innovative designs while
ensuring credibility of water phantoms.
