【摘要】：隨著超導(dǎo)技術(shù)、成像技術(shù)和計算機(jī)等相關(guān)技術(shù)在近幾年的發(fā)展,使得磁共振成像技術(shù)憑借其特有的優(yōu)勢,在醫(yī)學(xué)診斷領(lǐng)域得到了迅速的發(fā)展。如今,它已經(jīng)成為醫(yī)學(xué)影像領(lǐng)域中十分重要的一部分,并且在臨床應(yīng)用中得到了廣泛的應(yīng)用。作為目前最先進(jìn)的診斷技術(shù)之一,磁共振的成像效果和掃描時所選用的序列有著十分重要的關(guān)系。因此,一個高效率、方便用戶操作的脈沖序列開發(fā)環(huán)境對于磁共振系統(tǒng)有著非常重要的意義。磁共振診斷技術(shù)憑借著它無電離輻射、軟組織對比度高以及可提供任意斷層方向成像等特點(diǎn)得到了迅速的發(fā)展,東軟飛利浦醫(yī)療系統(tǒng)設(shè)備有限責(zé)任公司著手開發(fā)一種方便用戶操作的脈沖序列編譯器,本文開展了對圖形化脈沖序列編輯器的研究。隨著計算機(jī)技術(shù)的日漸成熟,也為本系統(tǒng)的研究奠定了基礎(chǔ)。本研究是在windows平臺下,基于C++語言進(jìn)行了功能的實現(xiàn),對脈沖序列的編輯,由過去的事件表表達(dá)的方式過渡到通過繪制圖形化脈沖序列圖的方式,從而實現(xiàn)了對掃描序列的編輯與可視化。系統(tǒng)主要包括基于圖形化的序列繪制模塊、參數(shù)模塊和事件表生成模塊三部分。對于序列繪制模塊,系統(tǒng)實現(xiàn)了繪制脈沖序列信號的直線、圓、折線、矩形等圖形功能,并且具有顏色、線型等設(shè)置、修改,撤銷、刪除、移動等功能以便在繪制脈沖序列圖時進(jìn)行對已有圖形的修改。為了方便圖形的繪制,系統(tǒng)還提供了背景網(wǎng)格；在參數(shù)模塊中,系統(tǒng)實現(xiàn)了對參數(shù)的設(shè)置并以文本形式保存；在事件表模塊中,對于編輯好的SE、FE序列進(jìn)行自動生成事件表并同樣以文本形式保存。通過研究實現(xiàn)了對脈沖序列編輯的圖形化,將原有的比較繁瑣的脈沖序列編輯過程給簡單化。
[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.
