New exciting Phantoms at our booth

Gold Standard Phantoms is scaling up with new products and services.

Visit our booth C04 at ISMRM 2024 to learn more and talk to our scientific team

Temperature Control Bundle  for NIST-calibrated Diffusion Measurements

Gold Standard Phantoms anticipated patented technology is here!

  • ALL MRI parameters are temperature dependent.
  • Unless this is accounted for, measurements on phantoms are inaccurate and not reproducible. But diffusion is the most sensitive parameters of them all with changes in ADC of 3% per °C
  • The Phase Change Material (PCM) is a flood-fill material that surrounds the samples in a MultiSample phantom, that melts/solidifies at 37°C.
  • Using the latent heat of this material, a phantom can precisely maintain its temperature for many hours (<1.0°C change for more than 8 hours).
  • While diffusion is our first application, scanning phantoms at body temperature will enable matching chemical shifts and exchange rates to those found in-vivo.

The New and Improved Gold Standard for ASL Perfusion MRI:

Relaunching QASPER v2.0

Why use QASPER?

Are you using ASL to track disease progression or response to treatment in clinical trials? Do you wonder if quantitative ASL values vary because of hardware or physiology?

QASPER can help you

  • Ensure consistency of your ASL acquisitions over time.
  • Develop new ASL pulse sequences.
  • Compare and benchmark data acquired from different ASL sequences and MRI scanners.

Come to speak to our CTO Monday, 06 May 2024 between 17:00 - 18:00 at the Exhibition Hall (Hall 403)

to discuss the results of QASPER in a 2-years long clinical trial (abstract 4883)!

Perfusion ground truth

The new QASPER v2.0 is a quantitative and traceable reference of known perfusion. By removing a major source of uncertainty (the variance in the porosity of the porous material used to simulate micro-vasculature), ASL measurements of perfusion in the QASPER phantom can be directly compared with the measured flow rate.
