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.
