1. A method for spatial resolution enhanced imaging, the method comprising:
determining a target region of a subject being imaged;
estimating an achievable spatial resolution;
selecting an increased spatial resolution that is greater than a predetermined spatial resolution and equal to or less than the achievable spatial resolution; and
acquiring image data of the target region with the increased spatial resolution, wherein a voxel or a pixel of the image data corresponding to a region of interest in the target region includes intrinsic partial volume effect and another voxel or pixel of the image data corresponding to a boundary of the region of interest in the target region includes extrinsic partial volume effect,
wherein a contrast between the region of interest and other tissue region in the image data acquired with the increased spatial resolution is greater than a contrast between the region of interest and other tissue region in the image data acquired with the predetermined spatial resolution due to the intrinsic partial volume effect.
