Visualization of the Magnetic Resonance Imaging Pulse Sequence

摘要

The pulse sequence is an important part of the magnetic resonance imaging (MRI). It is directly related to the resolution of medical image obtained by MRI, and other important parameters such as the imaging speed etc. Therefore, it is very important to develop newer and more efficient pulse sequence. This paper presents the visualization of the MRI pulse sequence. It can simplify the development process of new pulse sequence by designing the pulse sequence with graphical method to replace the current mode of directly using text programming language to design it. Using the concept of a sequence of events and custom identifiers, we establish a middle interface between design environment of graphical MRI pulse sequence and text format programming environment recognized by nuclear magnetic resonance equipment. It makes the pulse sequence design open sources, and achieves independent to hardware and software. To avoid the tedious and complex programming process, the design of MRI pulse sequence is more efficient.
