【摘要】：随着超导技术、成像技术和计算机等相关技术在近几年的发展,使得磁共振成像技术凭借其特有的优势,在医学诊断领域得到了迅速的发展。如今,它已经成为医学影像领域中十分重要的一部分,并且在临床应用中得到了广泛的应用。作为目前最先进的诊断技术之一,磁共振的成像效果和扫描时所选用的序列有着十分重要的关系。因此,一个高效率、方便用户操作的脉冲序列开发环境对于磁共振系统有着非常重要的意义。磁共振诊断技术凭借着它无电离辐射、软组织对比度高以及可提供任意断层方向成像等特点得到了迅速的发展,东软飞利浦医疗系统设备有限责任公司着手开发一种方便用户操作的脉冲序列编译器,本文开展了对图形化脉冲序列编辑器的研究。随着计算机技术的日渐成熟,也为本系统的研究奠定了基础。本研究是在windows平台下,基于C++语言进行了功能的实现,对脉冲序列的编辑,由过去的事件表表达的方式过渡到通过绘制图形化脉冲序列图的方式,从而实现了对扫描序列的编辑与可视化。系统主要包括基于图形化的序列绘制模块、参数模块和事件表生成模块三部分。对于序列绘制模块,系统实现了绘制脉冲序列信号的直线、圆、折线、矩形等图形功能,并且具有颜色、线型等设置、修改,撤销、删除、移动等功能以便在绘制脉冲序列图时进行对已有图形的修改。为了方便图形的绘制,系统还提供了背景网格；在参数模块中,系统实现了对参数的设置并以文本形式保存；在事件表模块中,对于编辑好的SE、FE序列进行自动生成事件表并同样以文本形式保存。通过研究实现了对脉冲序列编辑的图形化,将原有的比较繁琐的脉冲序列编辑过程给简单化。
[Abstract]:With the development of superconducting technology, imaging technology and computer technology in recent years, magnetic resonance imaging technology has been rapidly developed in the field of medical diagnosis with its unique advantages. Now, it has become a very important part of the medical imaging field, and has been widely used in clinical applications. As one of the most advanced diagnostic techniques, magnetic resonance imaging (MRI) has a very important relationship with the sequence used in scanning. Therefore, an efficient and user-friendly pulse sequence development environment is very important for magnetic resonance system. Magnetic resonance diagnosis (MRI) technology has been developed rapidly by virtue of its nonionizing radiation, high contrast of soft tissue and the ability to provide arbitrary fault direction imaging. Neusoft Philips Medical equipment Co., Ltd. began to develop a user-friendly pulse sequence compiler. In this paper, the graphical pulse sequence editor is studied. With the maturation of computer technology, it also lays a foundation for the research of this system. This study is based on the windows platform, based on C language for the realization of the function, the editing of the pulse sequence, from the past event table representation to the way of drawing graphical pulse sequence diagram, Thus, the editing and visualization of the scanning sequence are realized. The system mainly includes three parts: sequence rendering module based on graphics, parameter module and event table generation module. For the sequence rendering module, the system realizes the functions of drawing the pulse sequence signal such as straight line, circle, broken line, rectangle and so on, and has the setting of color, line shape, modification, cancellation, deletion, etc. Functions such as moving to modify existing images when drawing pulse sequence diagrams. In order to facilitate the drawing of the graph, the system also provides the background grid; in the parameter module, the system implements the setting of the parameters and saves them in the form of text; in the event table module, The event table is automatically generated for the edited SEFe sequence and also saved as text. The graphic editing of pulse sequence is realized, and the complicated editing process of pulse sequence is simplified.
