Where are HQ Imaging diffusion phantoms used?

HQ Imaging diffusion phantoms enable you to perform quality assurance of the complete diffusion imaging pipeline. A variety of customers can benefit from this wide range of applications: In everyday clinical practice, the diffusion phantoms can ensure the orderly functioning of diffusion MRI. In clinical research, diffusion phantoms ensure the comparability between different subjects of a study or even between different MRI systems at different locations e.g. in multicenter clinical trials. Diffusion phantoms are also an extremely valuable tool in the development of new diffusion MRI imaging sequences and post processing schemes, because they offer a well-defined ground truth in real MRI measurements.
