【摘要】：當(dāng)今世界范圍內(nèi),計算機(jī)斷層掃描技術(shù)(Computed Tomography,縮寫是CT)被廣泛的應(yīng)用于醫(yī)療和教育等領(lǐng)域。近些年來,隨著我國心臟,心血管疾病的發(fā)病率不斷高攀,心臟掃描,尤其是對冠狀動脈細(xì)節(jié)的掃描,已經(jīng)成為CT的重點(diǎn)應(yīng)用領(lǐng)域。然而由于心臟的周期搏動特性,如何提高心臟掃描的成像質(zhì)量同時降低患者受到的輻射劑量也成為了CT心臟掃描的重點(diǎn)和難點(diǎn)。 針對上述問題,這篇論文首先分析了當(dāng)前CT心臟掃描技術(shù)的研究現(xiàn)狀,例舉全球主要CT提供商在提高心臟掃描成像質(zhì)量和降低患者受到輻射劑量方面的各主流技術(shù)手段,提出其各自存在的問題。然后以某著名CT設(shè)備制造商的Emotion系列CT中心肺掃描接口(Cardio Pulmo Interface,縮寫為CPI)模塊為基礎(chǔ),進(jìn)行了深入的研究并且設(shè)計出了一種通過實時心電圖(Electronic Cardio Gram,縮寫是ECG),提高上述兩個指標(biāo)的系統(tǒng)設(shè)計實現(xiàn)。并在論文的結(jié)尾提出進(jìn)一步改良后的,更為嚴(yán)格的系統(tǒng)設(shè)計構(gòu)想。 首先討論了構(gòu)成該系統(tǒng)設(shè)計的功能模塊劃分：心電信號獲取模塊、心臟掃描接口模塊(本文所論述的系統(tǒng)設(shè)計的核心模塊)、掃描主控模塊、X射線發(fā)生模塊、數(shù)據(jù)管理系統(tǒng)以及圖像重構(gòu)模塊。 接著詳細(xì)的論述了該系統(tǒng)的核心實現(xiàn)算法。并且圍繞該算法的實現(xiàn),描述了心電信號獲取模塊、心臟掃描接口模塊、掃描主控模塊的功能劃分和相互間的控制和信息交互。然后對該算法在一些特殊心臟掃描需求和不同的掃描模式下的適應(yīng)性上進(jìn)行了分析。同時與其他幾種主流技術(shù)手段和業(yè)內(nèi)的發(fā)展方向進(jìn)行多角度的對比。 最后對該系統(tǒng)設(shè)計的技術(shù)擴(kuò)展相關(guān)內(nèi)容進(jìn)行了深入討論。
[Abstract]:Nowadays, computed tomography (CTT) is widely used in medical and educational fields.In recent years, with the increasing incidence of heart and cardiovascular diseases in China, cardiac scanning, especially for the details of coronary artery, has become a key application field of CT.However, because of the periodic pulsatility of the heart, how to improve the imaging quality of cardiac scan and reduce the radiation dose of patients has become the focus and difficulty of CT cardiac scan.In order to solve the above problems, this paper first analyzes the current research status of CT cardiac scan technology, and gives examples of the major CT providers in improving the quality of cardiac scan imaging and reducing the radiation dose of patients.Put forward their respective problems.Then it is based on the Emotion series of CT central lung scanning interfaces, known as the Cardio Pulmo Interface, a well-known manufacturer of CT equipment.This paper studies deeply and designs a system to improve the above two indexes by means of real-time electrocardiogram (ECG) and electronic Cardio Grammar (abbreviated as ECG).At the end of the paper, a more strict system design is proposed.Firstly, the functional modules that constitute the design of the system are discussed: ECG signal acquisition module, heart scan interface module (the core module of the system design discussed in this paper, scanning main control module, X-ray generation module, and so on).Data management system and image reconstruction module.Then the core algorithm of the system is discussed in detail.Around the realization of the algorithm, the paper describes the ECG acquisition module, the heart scan interface module, the scanning main control module function division and mutual control and information exchange.Then, the adaptability of the algorithm to some special cardiac scan requirements and different scan modes is analyzed.At the same time with several other mainstream technical means and the development direction of the industry to carry out a multi-angle comparison.Finally, the related contents of the technical extension of the system design are discussed in depth.
