1. A magnetic resonance imaging (MRI) system, comprising:
one or more components configured to acquire magnetic resonance data, the one or more components comprising at least one permanent magnet configured to produce a B0 field that is less than or equal to 0.1 T and greater than or equal to 50 mT;
a first controller; and
at least one processor configured to determine times to issue individual commands from the first controller to the one or more components;
wherein the first controller is configured to control the one or more components to operate in accordance with a first pulse sequence at least in part by:
receiving, from the at least one processor, a sequence of commands for controlling the one or more components to operate in accordance with the first pulse sequence; and
issuing at least one command of the sequence of commands to the one or more components, in accordance with the determined times to issue the at least one command.
