Finally, a quality, ground-truth diffusion phantom that can be used to assess and quantify both anisotropic and isotropic diffusion characteristics within a single, temperature-controlled device. The hollow Taxon™ fibers contained within the phantom are designed to precisely match the dimensional and diffusion characteristics of human axons. The phantom is compatible with all current generation 32/64 channel head coils and can be used to quantitatively assess and compare scanner performance between data collection sites. Gain confidence in the accuracy of study protocols with regularly repeated quality assessment scans using the Phantom Metrics family of products.
The MRI Diffusion Calibration Phantom is currently in development and is not yet available to order.
