Atherosclerosis is a major cause of ischemic stroke. In this study we build a 24-channel head coil array with a special designed coil arrangement to detect non-stenotic atherosclerotic plaques. We compare the 24-channel head coil with Siemens 32-channel coil. For imaging test, the g-factor maps of these two coil arrays are the same, which shows that the 24-channel coil has the same capability of paralleling imaging as the 32-channel coil, and SNR maps show that at the center of the phantom which corresponds to the intracranial region of the head, the 24-channel coil is as good as 32-channel coil.
