About the Metris X-Tek HMX ST 225 CT System

This scanner can be used for both reflection micro-CT and transmission micro-CT. Since a typical scan takes between 10-20 minutes it is convenient to use for imaging large numbers of specimens for scientific research and curation purposes.

It can be used to visualise a wide range of materials:

  • biological - including chitin, bone and dentine
  • mineralogical - such as fossils and rock cores
  • man-made - including plastic, carbon-fibre and metal

Technical details

  • Cone beam projection system
  • Four megapixel Perkin Elmer XRD 1621 AN3 HS detector panel
  • Volumes constructed using CT PRO (Metris X-Tek, UK) and visualised using VG Studio Max 2.0 (Volume Graphics, Heidelberg, Germany)
