<P>PROBLEM TO BE SOLVED: To provide a gradient driver for magnetic resonant imaging improved in thermal instability and/or electrical losses. <P>SOLUTION: The gradient drivers (58, 100, 122) configured to deliver a pulse sequence to gradient coils (26, 28, 30) are interleaved. Two or more interleaved drivers (102, 104, 112, 114) can be included such that a high amplitude pulse is output by operating the two interleaved parts (102, 104, 112, 114) while spreading the electrical loss and maintaining the thermal stability of a system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
