The field of MRI is rapidly moving towards more quantitative approaches. In this context, virtual phantoms that would provide a reference signal could be useful for quantification purposes in MRI. The aim of the present study was i) to implement a dedicated experimental set-up to generate MR images of virtual phantoms ii) to test its temporal stability and signal linearity. This approach is here referred to as Virtual Phantom (ViP) MRI. MR images of virtual phantoms were generated using a stand-alone, independent unit. Thus, ViP MRI can be performed on MR scanners from different vendors.
