Imaging - Medical & Security

For Better Patient Outcomes and Safeguards

As a worldwide leader in advanced engineered materials, we have developed a range of products to help meet the complex needs of the security and medical markets. These markets are looking to continuously improve their speed of measurement and image resolution, which requires ever-evolving detector designs. We continue to collaborate with our customers in these industries to meet their current and future needs for high-quality imaging. Our portfolio of products includes LYSO, CsI(Tl), CdWO4, BGO, NaI(Tl), LaBr3(Ce)/Enhanced LaBr3, and PVT.

MRI Imaging 

CsI(Tl)

  • Low afterglow
  • High light output
  • Good radiation hardness properties

LYSO

  • Three to four times the light emission of BGO
  • High density and short decay time
  • Fast, single exponential decay time most PMTs

CdWO4

  • Withstands high energy radiation damage
  • High density and stopping power
  • Suitable for low activity counting applications

BGO

  • High density, high Z scintillator
  • Good photopeak to Compton ratio
  • Scintillator of choice for neutron activation analysis and active Compton shields

NaI(Tl)

  • High light output
  • No significant self-absorption of scintillation light
  • Emission spectrum well matched with the sensitivity curve of photomultiplier tubes (PMTs) with bialkali photocathodes

LaBr3 and Enhanced Lanthanum Bromide

  • Fast emission enabling high count rate capability for extended measurement capability (time of flight, fast analysis)
  • Excellent light output stability with temperature to allow the best identification performance, even if high temperature
