title: Fast scan and echo planar MR imaging technology.
abstract: The development of imaging technology for acquiring ever-faster images has been an ongoing activity since the early years of MR imaging development. This article gives the reader a sense of the range of technical challenges faced by the developers of faster imaging hardware and some of their solutions. Before reviewing the technical issues, however, the authors briefly discuss the marketplace realities that have led to technology decisions and, to a certain extent, the prolonged pace of development of the hardware.
