PROCÉDÉ DE GÉNÉRATION D'UNE SÉQUENCE D'IMPULSIONS DE RÉSONANCE MAGNÉTIQUE AU MOYEN DU TRAITEMENT DES ÉVÉNEMENTS DE MANIÈRE RÉCURSIVE

摘要

In one aspect the invention relates to a method generating control commands for execution on an MR scanner (MR1, MR2). The method comprises: Receiving (S1) an MR sequence via an input interface (101); Partitioning (S2) the MR sequence in a sequence of time slices (ts1, ts2,...tsn; Defining (S3) an extendable set of sequence block control data types (sb1, sb2,...sbn), wherein a sequence block control data type (sb1, sb2,...sbn) represents a formalized and a self-contained description of a time slice (ts) of the MR sequence; Mapping (S5) each time slice (ts) to at least one instance of a sequence block control data type (sb) or to at least one instance of a fundamental control data type (f) for providing (S6) a stream of events (e1, e2, ..ei); Providing (S7) an event handler (EH) for each event (e) wherein each of the event handlers (EH) is adapted for processing at least one event (e); Accessing (S8) a dispatcher (D) for reading each event (e) in the provided stream of events and passing each event (e) together with the dispatcher (D) itself to an appropriate event handler (EH), so that the dispatcher (D) may be called recursively by the event handlers (EH). Finally, fundamental control data types are translated into concrete control commands of the particular scanner to be used for execution on the MR scanner (MR1, MR2).
