Abstract
A phantom for magnetic resonance imaging (MRI) using surface coils was developed. This phantom, which is made from a combination of a single signal-producing material and a non-signal-producing material, can be used to simulate small low-contrast regions in the surrounding tissue. MR images of this phantom showed changes in contrast resolution and spatial resolution corresponding to the contrast characteristics detected under varying scan conditions. These changes in contrast resolution and spatial resolution were visually confirmed on MR images of the phantom. The results indicate that this phantom can simulate low-contrast tissue, mimicking regions in the surrounding simulated normal tissue.
