Close fitting is extremely crucial for RF coil arrays in order to maximize sensitivity. It is impossible to closely fit for all subjects of various head sizes using rigid head coil arrays. We presented a novel design of partially flexible 32-channel coil array to address the issue. The inner dimensions of the coil array can be smoothly adjusted from 180mmx220mm to 220mmx 260 mm, which fit for almost all head sizes of adult human subjects. The experiment results showed high imaging quality within the adjustable ranges. The coil array is highly practical for both research and clinical settings.
