Method for improving output rate of magnetic resonance imaging pulse sequence generator

The invention discloses a method for improving the output rate of a magnetic resonance imaging pulse sequence generator. The method includes: a spectrometer computer performs index coding on pulse sequence information, records the length of information corresponding to an index code, and writes the index code, the length of the information corresponding to the index code, and the information corresponding to the index code into a memory of the pulse sequence generator; and after the starting of scanning, preposed decoding is performed by the pulse sequence generator to obtain the pulse sequence information, and update output is realized. By employing the method, the pulse sequence information corresponding to the index codes can be read in batches, the preposed decoding and update output are synchronously performed, and the output rate of the pulse sequence generator is increased. 本发明公开了种提高磁共振成像脉冲序列发生器输出速率的方法，该方法由谱仪计算机对脉冲时序信息进行索引编码，并记录索引码所对应信息的长度，然后将索引码、索引码所对应信息的长度、索引码所对应的信息分别写入脉冲序列发生器的内存中；启动扫描以后，由脉冲序列发生器进行前置
