Water Equivalent Material, various inserts and empty bottles enable to verify the appropriate Multi-Energy CT settings

 

Multi-Energy CT (MECT) or Dual Energy CT (DECT) is a new frontier of rapidly advancing medical imaging, and now 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, verification of protocols, expansion of clinical application, to derive the maximum benefits from the technology.

Applications

Study for

  • ME-CT image analysis protocol
  • Metal artifact reduction
  • Reduction of contrast media

 

Evaluation Parameters

  • Uniformity
  • Signal-to-noise ratio (SNR)
  • Image contrast
  • CT dose index (CTDI)

FEATURES

  • Phantom using innovative Aqua Slab (Water Equivalent Material)
  • CTDI measurement
  • Metal artifact reduction
  • Two different sizes of body (TR-I, TR-J)
   

Aqua Slab

  

Aqua Slab (Water Equivalent Material)

Aqua Slab has high equivalency to water in diagnostic energy ranges(40-190KeV)

Experiment

  • Methods: Place the materials inserts on water tank (Materials: Aqua Slab / soft tissue / tough water / polyurethane / adipose tissue)
  • CT images: Rods are not shown in the CT images
    • (above) Aqua Slab: Nine rods of WEM are "invisible" under CT
    • (below) conventional materials: Two rods of Aqua Slab and for conventional water, adipose and soft tissue equivalent material, and polyurethane
  • Result: Aqua Slab has high equivalency to water

Supports iodine quantification and materialde composition

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 and inside rods.
