Improving temporal resolution without compromising spatial resolution has the potential to improve differential diagnosis in breast cancer. Several accelerated imaging methods exist that may aid in this endeavor but it is difficult to quantitatively measure and compare their respective performance. To address this problem, we have created a digital breast phantom comprised of enhancing lesions surrounded by normal background breast tissue. This phantom provides realistic, simulated k-space data for both Cartesian and non Cartesian acceleration methods. We describe the creation of this phantom and demonstrate its use.
