The test is generally considered the heart of the "gold standard" cardiac catheterization and angiography. It is most commonly used to determine the incidence of CAD the location and severity. 然而,由于存在创伤性和潜在的复杂性,心脏导管介入操作是一种典型需要住院治疗的昂责方法.因此,心脏导管介入操作通常只在病人进行其它非创伤性试验诸如心脏负荷试验时产生明显异常结果时才使用。 However, due to trauma and potential complications, cardiac catheterization operation is expensive responsible A typical method requiring hospitalization. Thus, cardiac catheterization operation usually only other non-invasive test in patients with cardiac stress testing such as is generated when markedly abnormal results when using. 估计每年进行的超过一百万的心脏导管介入操作花费30—50亿美元。 It estimated that over one million cardiac catheterization interventional procedures performed annually spend $ 30-50 billion. 心脏负荷试验在评估心脏及其冠状动脉方面特别重要,这是由于当对处于静息状态的病人进行测试时CAD的出现及其效力常常被忽略。 Cardiac stress test is particularly important in the evaluation of heart and coronary arteries, which is due to the patient when in the resting state CAD test their effectiveness appears often overlooked. 只有在通过踏车或骑车运动使心脏受负荷,或对由于种种原因不能进行实际身体运动的病人的心脏施用特殊化学品或药品(药致负荷),从而产生最大运动量来使心脏受负荷的情况下,才能在大量人群中可靠地检测到CAD症状.目前,最常用的负荷试验包括运动(踏车)负荷试验,负荷心脏回波困(超声)以及核灌注负荷试验,这三种测试在复杂性、准确率、有效性和成本上各有不同。 Only by moving treadmill or bicycle with a load on the heart, or cardiac patient for various reasons can not be the actual physical movement of administering particular chemicals or drugs (drug-induced load) to produce the maximum amount of motion of a load on the heart case, a large number of people in order to reliably detect the symptoms of CAD. currently, the most common stress test include sports (treadmill) stress test, stress cardiac echo sleepy (ultrasound) and nuclear perfusion stress test, three tests complexity, accuracy, vary on the effectiveness and cost. ECG运动负荷试验是最广泛有效和使用的负荷试验,并且操作起来成本最低。 ECG exercise test is the most widely used and effective load test, and the lowest cost to operate. 它依赖于探测12-导联的心脏回波图上ST段的变化;其准确度不断变化,产生大量假阳性和假阴性的结果。 It relies on detecting changes in the ST segment of the 12-lead cardiac echo; changing its accuracy, a large number of false positive and false negative results. 因此,病人在使用心脏回波描记术和放射性核闪烁扫描法进行负荷试验时通常要进行补充成像。 Thus, when the patient heart load test using echography and radionuclide scintigraphy supplement typically imaged. 心脏回波描记术和放射性核闪烁扫描法负荷试验的复杂性需要其由专家进行操作和评估。 Tracings and complexity of operation load test radionuclide scintigraphy in need thereof an echo heart operation and evaluated by experts. 典型的, 一个经培训的超声技师或心脏专家操作一个压力心脏回波图,而具备搮作放射性同位素资格的技师和心脏专家或放射专家一起进行核灌注负荷试验。 Typically, an operating pressure of a cardiac echo ultrasound technician by training or heart specialists, while Li has made radioisotopes qualified technician or radiologist and cardiologist nuclear perfusion stress test together. 为了得到准确的诊断, 需要心脏病专家来评估两个测试记录的结果,典型的,心脏病专家基于对病人的身体和病史的认识和其临床判断来选择进行试验。 In order to get an accurate diagnosis, you need a cardiologist to assess the results of two test recording, typically, a cardiologist based on knowledge of the physical and medical history of the patient and their clinical judgment to select the test. 每一种试验都有一定程度的不准确性。 Each test has a certain degree of inaccuracy. 心脏回波描记术有接近10-15 %的失误率,此时诊断无法进行。 Cardiac echography nearly 10-15% of the turnover rate, the diagnosis is not possible at this time. 可能阻止俘获用于诊断的优质图像的陣碍可造成这样的失误率。 May prevent the capture of high quality images for diagnosis of obstruction can cause such array error rate. 胸外科手术受损的组织,病人过多的身体脂肪和获取肺中过量氣气的肺异常就是这样的障碍的实例。 Thoracic surgery damaged tissue, the patient too much body fat and get the lungs of excess gas gas lung abnormalities are examples of such disorders. 由于种种原因,压力心脏回波描记术试验也会产生大量假阴性结杲。 For various reasons, the stress on the heart echography test will produce a large number of false negative Gao. 核灌注负荷试验高度敏感,并且易产生同样大重假阳性结果。 Nuclear perfusion stress test is highly sensitive, easy to produce as large and heavy false positive results. 每年进行的超过130万的负荷心脏回波描记术试验具有10-15%的失误率,即每年潜在地进行了超过l亿美元不必要的或不可靠的负荷心脏回波描记术试验。 More than 1.3 million of the workload of the heart echography tests carried out with a 10-15% annual turnover rate that year was potentially more than l billion dollars of unnecessary or unreliable workload of the heart echography test. 这种负荷回波试验的失误率造成了已知具备高频率假阳性结果的核灌注负荷试验数量上升。 This error rate test load echo caused a number of nuclear perfusion stress test known to have a high frequency of false positive results increase. 一次假阳性心脏负荷试验可能增加昂责而不必要的心脏导管介入搮作的次数以及与此相关的必需的住院治疗以及增加了病人的焦虑,不适,并增加了医疗风险。 A false positive cardiac stress test may increase Aung responsibility and unnecessary cardiac catheterization as well as the number of Li necessary hospitalizations associated with this treatment, and increased patient anxiety, discomfort, and increased medical risks. 负荷心脏回波描记术的大量假阴性结果可能增加了心脏发病风险和由于未发现的较重CAD而猝死的危险,和/或减少了在早期CAD阶段较早地成功干预的可能.因此,心脏诊断需要降低成本、增加准确率和/或增加有效的负荷试验。 Stress cardiac echography of a large number of false-negative results may increase the risk of heart and dangerous due to the heavy CAD undiscovered and sudden death, and / or reducing the possibility of CAD in the early stages of a successful early intervention. Therefore, heart diagnosis need to reduce costs and increase accuracy and / or increased effective load test. 发明内容本发明的实施例提供用于显示病人心脏信息的方法、系统和/或计算机程序产品。 The method provided for displaying information about the patient's heart, the system and / or computer program product SUMMARY Embodiments of the present invention. 病人心脏的多个MRI电影环路(cine loop)是在多个心率下和药物学和/或运动产生的负荷等级下得到的。 A plurality of patient cardiac MRI film loop (cine loop) is obtained at the load level at a plurality of heart rate and pharmaceutically and / or Movement. 所述的多个电影环路包括室壁运动困像帧的室壁运动电影环路和至少一个心脏位置的灌注图像。 The loop includes a plurality of film perfusion image kinesis trapped wall motion image frame and at least one loop of the film of the heart. 室壁运动电影环路和灌注电影环路同时显示。 Perfusion and wall motion movie movie loop the loop displayed simultaneously. 某些实施例中,灌注围像至少是关于心脏在至少一个位置处灌注图像的电影环路。 In certain embodiments, perfusion loop around the film is at least about as cardiac perfusion image at at least one location. 进一步的实施例中,灌注困像是心脏在一个位置处的心肌延迟增强(MDE)的灌注图像,本发明特别的实施例中,通过调整所述多个MRI电影环路以提供在每一个MRI电影环路中具备相同帧的补偿电影环路.进一步说,所迷多个MRI电影环路可在对病人进行负荷试验时得到。 In further embodiments, such as cardiac perfusion trapped delayed enhancement (MDE) of the myocardial perfusion image at a position, in particular embodiments of the present invention, by adjusting the plurality of MRI to provide a film loops each MRI have the same film frame loop compensation film loop. further, the plurality of fans loop may MRI film obtained when the patient load test. 也可通过对显示的MRI电影环路评估来确定心肌缺血与否,或基于所述显示的电影环路的心肌活力。 May also be determined by the film loop MRI assessment of myocardial viability myocardial ischemia displayed or not, based on the display or movie loop. 在本发明的又一个实施例中,针对单个剂量的负荷诱导刑或运动量,同时显示与病人心脏相关的不同位置的多个电影环路。 In still another embodiment of the present invention, a dose for a single sentence or a load induced by exercise, simultaneously displaying a plurality of loops of different positions of the film associated with the patient's heart. 也可针对不同负荷诱导药的剂量,同时显示与病人心脏相应的单个位置的多个电影环路。 Dose of drug may induce different loads, simultaneously displaying a plurality of film loops patient's heart corresponding to a single location. 本发明的进一步实施例中,所述多个MRI电影环路通过增加帧和/或把帧从至少一个所述多个MRI电影环路中移除来进行调节。 A further embodiment of the present invention, the plurality of MRI movie loop be adjusted by increasing the frame and / or the frame is removed from the at least one of the plurality of MRI movie loop. 帧可加入到各个MRI电影环路中和/或从其中移除,从而使得所有显示的MRI 电影环路具备相同的帧数,进一步讲,增加的帧可以通过重复一个MRI 电影环路的帧来获得。 MRI can be added to each frame of the film loop and / or removed from it, so that all the film MRI display with the same number of frames of the loop, Further, the frame may be increased by repeating a frame MRI movie loop obtain. 加进或移除的帧可以在整个MRI电影环路中平均分布。 Add or remove frames can be evenly distributed throughout the MRI film loop. 本发明的另一个实施例中,通过补偿室壁运动MRI电影环路而使得所述多个室壁运动MRI电影环路中的每一个中的相应帧与病人心脏循环中的常规部分相协调,这样,不同电影环路中的帧可能对应不同的持续时间,然而,每一帧可对应心脏周期的相同份额时间。 Another embodiment of the present invention, by compensating for wall motion MRI movie loop such that the plurality of wall motion MRI film loops each respective frame portion coordinated with a conventional patient's heart cycle, in this way, different movie loop frame may correspond to a different duration, however, each frame may correspond to the same time the share of the cardiac cycle. 进一步说,所述多个MRI电影环路也可通过调整多个MRI电影环路中的至少一个的帧显示的持续时间而得到调整,从而每一个MRI电影环路具备共同的总的持续时间.本发明的另一个实施例中,通过在多个心率下获取病人心脏的多个MRI电影环路来显示病人的心脏信息,所述多个电影环路包括含有室壁运动图像帧的电影环路.还获得心脏至少一个位置处的灌注困像。 Further, the plurality of MRI film loops can also be adjusted by the duration of at least one of a plurality of frame alignment film loop MRI display, so that each loop is provided with a film MRI common total duration. another embodiment of the present invention, the patient's heart to display the information acquired by the patient's heart at a plurality of heart rate plurality of loops MRI film, said film comprising a plurality of film loop comprising a loop moving image frame wall also get trapped like cardiac perfusion at least one location. 室壁运动电影环路和至少一个灌注困像同时显示。 Wall motion movie loop and at least one perfusion trapped like displayed simultaneously. 本发明的某些实施例中,灌注图像是提供灌注图像电影环路的多个灌注图像。 Certain embodiments of the present invention, the perfusion image is a perfusion image to provide a plurality of perfusion images of the film loop. 这种情况下,通过同时显示室壁运动电影环路和至少一个灌注图像电影环路来同时显示室壁运动电影环路和至少一个灌注图像。 In this case, by simultaneously displaying wall motion movie loop and at least one perfusion image movie Loop to simultaneously display wall motion movie loop and at least one perfusion image. 本发明的另一个实施例中,灌注图像是心肌延迟增强灌注图像.本发明的另一个实施例中,提供了MRI成像评估的用户界面.用户界面可在显示设备上显示,并且包括至少一个设置成显示心脏室壁运动的MRI图像的多个电影环路的区域和至少一个被设置成显示心脏灌注的至少一个MRI图像的区域.被设置成得以显示心脏灌注的至少一个MRI图像的区域可以设置成得以显示心脏灌注MRI图像的至少一个电影环路。 Another embodiment of the present invention, the perfusion image is a myocardial delayed enhancement perfusion image.

Figure 4 depicts operation in accordance with certain embodiments of the invention within the scope of the present invention. 如图4所示,对病人进行负荷试验(模块400 )并且在负荷试验期间釆集表示病人心脏的室壁运动和灌注的MRI困像(模块402 )。 4, the patient load test (block 400) and preclude set represents the patient's heart wall motion and perfusion MRI trapped image (block 402) during a load test. 所述负荷试验可以是采集MRI图像时可进行的任何类型的负荷试验.MRI负荷试验的一个具体的实施例为使用诸如多巴酚丁胺或类似物生物化学诱导负荷试验,进行负荷试验对本领域技术人员是熟知的,因此不在这里进行描述。 The load test may be a specific embodiment of the load test .MRI any type of load test when acquiring MRI image may be used such as dobutamine induced load or the like, a biochemical test, a load test in the art It is well known in the art, and therefore not be described herein. 采集的灌注围像可以是在给用造影剂后立即采集的"首先通过" 的灌注图像。 Acquired perfusion images may be enclosed in a contrast agent immediately after collection "first pass" perfusion image. 这种情况下,灌注图像可以是图《象的电影环路,从而造影剂的灌注可由电影环路图像示踪或监控.灌注电影环路图像可以是心脏不同部位的多个灌注电影环路图像。 In this case, FIG perfusion image may be "like the film loop, such that the perfusion of the contrast agent or may be a movie loop tracer monitoring image. Perfusion loop movie image may be perfused a plurality of different parts of the image film loop . 这些电影环路可由室壁运动电影环路图像记录,从而灌注电影环路和室壁运动电影环路对应几乎相同的位置,例如,灌注电影环路可以是三个对应三条短轴室壁运动电影环路的电影环路。 These films may be loops of wall motion picture film loop recording, so that the film loop perfusion and wall motion movie loop corresponding to almost the same position, e.g., a movie loop may be perfused three corresponding three short axis wall motion cine loop film loop Road. 因此,灌注图像可以在和短轴室壁运动图像在通过心脏的相同的平面上采集。 Thus, the perfusion images may be acquired and a minor wall in the moving image on the same plane through the heart. 可以选择的是,或除了产生灌注图像电影环路以外,也可提供心肌延迟增强(MDE) , MDE中,给用造影剂例如钆DPTA20分钟后,其一部分渗入坏疽的(坏死的)组织并将变得明亮(因此,被延迟增强)。 Can be selected is, or in addition to the film loop perfusion image is generated, may also be provided myocardial delayed enhancement (MDE), MDE, a contrast agent such as gadolinium to DPTA20 minutes later, a portion of the infiltration necrosis (necrotic) tissue and brighten (Thus, the delayed enhancement). 这些图像可以不以电影环路方式,而以单独困像方式采集,并记录(在相同切片位置处)相应灌注和/或室壁运动困像。 These images may not be in a movie loop manner, but in a separate manner like trapped collected, and records the perfusion (at the same slice position) and / or trapped wall motion image. MDE是另一种形式的灌注,也就是说,它是坏死组织的灌注,即,首先通过的灌注是活组织的灌注。 MDE is another form of perfusion, that is, it is necrotic tissue perfusion, that is, through the first infusion of living tissue perfusion. 因此,灌注困像可能包括诸如MDE困像和/或困像电影环路的单独图像,上述其中之一或两者均可与室壁运动图像一同显示。 Thus, the perfusion images may include information such as MDE trapped trapped like and / or individual images like a movie trapped loop, wherein one or both of the above can be displayed with the wall motion images. 对可提供在心脏不同位置的心跳的电影环路和/或不同剂量的负荷诱导刑的MRI室壁运动图像被时间同步,并建立灌注图像的数目, 以使每一个电影环路具备相同数目的MRI图像或帧,从而每一个电影环路可以被显示相同的时间(模块404 )。 May be provided at different locations of the heart beat of the film loop and / or MRI images of wall motion induced load penalty different doses are time synchronized, and establishes the number of perfusion images, so that each loop includes the same number of movie MRI images or frames, so that each loop may be a film show the same time (block 404). 因此,例如,灌注电影环路可通过使其和室壁运动困像以同样的速率来循环显示而与室壁运动电影环路同步。 Thus, for example, a movie loop perfusion and wall motion can be trapped by it at the same rate as the display cycle is synchronized with the film loop wall motion. 灌注电影环路的同步还可通过增加帧数,减少帧数或如这里所描述的调整显示时间来实现。 Film perfusion loop can also be synchronized by increasing the number of frames, such as adjusting the number of frames or the display time described herein is achieved. 室壁运动电影环路还可与心脏周期同步,使得每一个电影环路在心脏循环的相同部分开始。 Film loops and wall motion of the heart cycle can also be synchronized so that each film loop start at the same portion of the heart cycle. 补偿的室壁运动电影环路和灌注围像和/或灌注困像的电影环路例如可供工作站显示,并且可以对两者进行评估来确定病人的心脏生理状态(模块406 )。 Wall motion and perfusion loop compensation film as enclosed and / or perfusion trapped image display workstation for example, the film loop, and may both be evaluated to determine the physiological condition of the heart of a patient (block 406). 这样的评估例如可通过显示几种或所有剂量下一给定位置处的室壁运动和灌注电影环路和/或显示某一给定剂量下几个或所有位置的电影环路来进行,通过显示接近实时获取的图像可进行评估。 Such evaluation may be, for example, by displaying some or all dosage wall motion at a given location and the next movie loop perfusion and / or display a given dose or at several positions of the film to all loops, by near real-time display captured images can be evaluated. 此外或可选地,可以与室壁运动电影环路一起显示一个MDE 图像或多个MDE图像。 Additionally or alternatively, it may display one or more images MDE MDE wall motion images with movie loop. 显示的电影环路和/或图像可由生理学家进行评估,以确定心脏的生理状态。 Film loops and / or image display may be physiologist evaluated to determine the physiological state of the heart. 这样的确定例如可包括确定CAD存在与否,CAD严重性的变化,心脏治疗体制的效果等,例如,灌注图像可以和室壁运动图像进行比较,以确定减少的灌注区域是否与受损室壁运动区域相对应,从而进一步确定血管是否堵塞.这样的操作可以重复,直到期望位置(模块408 )和期望负荷等级(模块410)的MRI图像被获得和补偿,如此处所述。 Such a determination may include determining the presence or absence of, for example, changes in the severity of CAD, heart treatment effect CAD system or the like, for example, the image may be compared to perfusion and wall motion images, to determine whether the damaged region of reduced wall motion perfusion region corresponding to further determine whether the blood vessel blockage. such operations may be repeated until a desired position (block 408) and the desired load level (block 410) the MRI image is obtained, and compensation, as described herein. 因此,如果要釆集更多的视图(模块408 ),则继续进行采集其它MRI图像(模块402 )的操作。 Therefore, to preclude More view (block 408), then proceed with other MRI image capture operation (block 402). 如果要评估另外的负荷等级(模块410),则继续进行其它的负荷试验(模块400 )。 If additional load level to be evaluated (block 410), then proceed with other load test (block 400). 已经发现,在时间上同步电影环路使得生理学家可以更加有效地评估心脏生理状况,而不会通过时间同步处理产生明显的赝像和/或失真,而这些赝像和/或失真会使信息模糊或提供导致无^1评估的错误信息。 It has been found in the time synchronization makes the movie loop physiologist can more effectively assess the physiological condition of the heart, and does not sync produce significant artifacts and / or distorted by time, and these artifacts and / or distorted information will blurred or provide lead-free ^ 1 error messages assessments. 进一步发现,电影环路时间同步提高了MRI电影环路评估的有效性,因为它允许生理学家同时可视地比较不同心率下的心脏运动,其中心脏运动在心脏周期中其相同位置的显示是同步的。 Further found that the film loop time synchronization loop improves the effectiveness of MRI assessment of the film, because it allows the movement of the cardiac physiologist while visually compare different heart rate, which show the same position in the cardiac cycle in which the heart movement is synchronized of. 因此,每一显示的图〗象在心i^中占几乎相同比例的时间.因此,可以直接比较不同心率下处室壁运动的不同之处,以探测病症的存在.如上面所讨论,已经发现这里所描述的时间同步处理可避免产生不准确、赝像或其它可能妨碍评估过程的失真的显示.进一步说,评估过程可以以充分的实时方式进行,从而可使生理学家利用MRI电影环路在进行负荷试验时来监控负荷试验。 Thus, each display of FIG〗 i ^ accounted for approximately the same time as the proportion of the heart. Thus, except directly compare Xiachu heart wall motion, to detect the presence of the disorder. As discussed above, it has been found time synchronization processing described herein may avoid inaccurate, artifacts or other distortions may prevent the display of the evaluation process. further, the evaluation process can be performed in real time sufficient to allow an MRI film loop physiologist to monitor the test load when the load test. 这样的监控在进行负荷试验和基于负荷试验结果对病人状况进行评估中均实用,通过提供这样的允许同时直接比较不同心率数据的电影环路信息,生理学家可以快速确定病人心脏生理状态,从而调整试验参数和/或避免伤害病人。 Such testing and monitoring the patient during the load based on the load condition of the test results for evaluation are useful, by providing a film loop allows direct comparison of different information at the same heart rate data, physiologists can quickly determine the physiological state of the patient's heart, thereby adjusting The test parameters and / or to avoid harm to the patient. 在有些情况下,例如在负荷试验全过程中存在静息心脏室壁运动异常时,或存在同心左心室肥大的状况下,室壁运动评估不足以确定局部缺血。 In some cases, for example, present during the whole test load resting cardiac wall motion abnormalities, the presence or status of concentric left ventricular hypertrophy, is not sufficient to assess wall motion determining ischemia. 由于这样的原因,对心脏灌注和/或延迟增强和电影室壁运动的联合评价可提高鉴别者确定在单独评估室壁运动时不明显的心脏坏死或局部缺血的能力.本发明的另一个进一步的实施例中,采用困像处理技术可以自动或半自动的进行电影环路的评估。 For these reasons, a joint evaluation of cardiac perfusion and / or delayed enhancement film and wall motion can be improved by determining the discriminating ability of the heart ischemia or necrosis obvious when used alone assessment of wall motion. The present invention further in a further embodiment, image processing techniques may be trapped using automatic or semi-automatic assessment of the film loop. 由于采用同样大小的数据设备并且数据设备中的相应帧对应心脏循环中的公共部分,因而电影环路的时间同步有助于这样的自动评估.例如,电影环路或电影环路中的部分图像可相互比较或参考,从而突出基线电影环路的偏差。 As a result of the same size and data device corresponding to the frame data corresponding to the common portion of the device of the cardiac cycle, and thus the film loop facilitate such automatic time synchronization evaluation. For example, a movie film image loops or loop portions can be compared with each other or with reference to a baseline projection deviation of the film loop. 因此,例如, 基线室壁运动电影环路可以和不同刑量电影环路比较并显示差异,和/或与阈值比较,以提供指示和/或心脏生理的评估.这些差异也可与灌注电影环路或同一区域的电影环路比较,以及与低灌注区域和异常室壁运动区域相比较。 Thus, for example, a baseline wall motion and display the movie loop may compare the differences, and / or compared with a threshold value to provide an indication and / or assessment of cardiac electrophysiological and different amounts film loop sentence. These differences may perfusion cine loop film loop Road or in the same region is relatively well compared with low perfusion and regional wall motion abnormalities region. 由于每一个电影环路中的位置对应心脏周期中几乎相同的时间,从而不同电影环路的相似位置的帧可以直接进行相互比较,因而这种电影环路的比较成为可能和/或简化。 Since each of the film loop position corresponding to the cardiac cycle time is almost the same, so that different positions of the film frame similar to the loop may be directly compared with each other, so that the film loop comparisons possible and / or simplified. 例如,自动比较还包括记录不同电影环路到基线环路。 For example, an automatic comparison also includes different recording a movie loop to loop baseline. 这样的记录可通过采用常规模式识别和/或校正技术进行,从而电影环路的相应象素或电影环路部分的每一个与病人身体中近似相同的生理位置相关联。 Such recording may be carried out by using conventional pattern recognition and / or correction techniques, so that each respective pixel of the film or film loop portion of the loop of the same approximate physiological location associated with the patient's body. 具体的实施例中,比较可以是3维(x, y, t) , 4维(x, y, z, t)和/或5维(x, y, z, t,剂量)。 In specific embodiments, the comparison may be a three-dimensional (x, y, t), 4-dimensional (x, y, z, t) and / or a 5-dimensional (x, y, z, t, dosage). 可以通过重复图像,增加或减少困像显示时间和/或从电影环路中去除图像来对电影环路进行补偿。 By repeating the image, increasing or decreasing the trapped image display time and / or removing an image from the film loop to compensate for the film loop. 电影环路可以通过提供每个环中相同数目的图^f象或帧来实现时间同步。 By film loop may provide the same number of each ring ^ f FIG image frames or time synchronization. 因此,病人的每一个显示的心跳可以显示相同的时间周期获取电影环路时的心率无关。 Thus, each of the patient's heartbeat display can show the same period of time get the heart rate when the movie has nothing to do loop. 具有较多帧的环路可以移去帧,而具有较少帧的环路可以增加帧。 Having a loop frame can be removed more frames, the frame loops having fewer frames may be increased. 帧可通过重复环中的帧来增加。 Frames may be increased by repeating the ring frame. 帧还可通过增加帧显示的时间的实质方式来增加。 Frame may also be increased in real terms by way of increasing the frame display time. 这种实质上帧的增加对存储的需求较之循环中物理重复帧要少。 This substantially increases the demand for storage in the frame than the frame cycle is repeated physical less. 增加或除去的帧可以分布在整个环路中,或优选基本上平均的分布在整个环路中。 Increased or removed frames may be distributed throughout the loop, or preferably substantially equally distributed throughout the loop. 进一步地,电影环路可与病人心脏周期同步,从而每一个电影环路在心脏周期的近似相同的部分开始,使MRI电影环路和病人心脏周期同步的技术对本领域的技术人员是已知的,因此在此不进行论述。 Further, the film loop may be synchronized with patient cardiac cycle, so that each film loop beginning at approximately the same portion of the cardiac cycle, so that the film loop and MRI patient cardiac cycle synchronization skilled in the art is known in the art and therefore it will not be discussed. 在本发明的具体实施例中,电影环路实时进行显示,其余实施例中,电影环路接近实时进行显示.对经受负荷试验的病人的电影环路的如此实时或接近实时的显示可通过允许对负荷试验进行快速分析和监控,从而可避免对病人的伤害,因而提供了安全的负荷试验,在其它实施例中,电影环路的显示由储存信息提供,并可进行"离线"操作。 In a particular embodiment of the present invention, the film loop real-time display, in the remaining embodiments, the film loop near real time display. Patients thus subjected to the load test or near real-time movie loop by allowing real-time display for rapid analysis and stress test monitoring, thereby avoiding injury to the patient, thereby providing a safe load test, in other embodiments, the film loop store information provided by the display, and can be "offline". 这种离线分析适合于详细或更耗时的电影环路分析。 This is suitable for detailed offline analysis or time-consuming film loop analysis. 进一步地, 数据采集、图像构建和/或电影环路困像的传送可相互重叠,从而减少图像采集和显示之间明显的传输延迟时间。 Further, data acquisition, image construction and / or loop transfer film image may overlap each other difficulties, thereby significantly reducing the transmission delay between the image acquisition and display time. 图5是按照本发明的实施例的电影环路显示器500的屏幕截取图。 Figure 5 is the film loop embodiment of the present invention, the display screen 500 of FIG taken. 如图5所示,多个电影环路502同时显示.电影环路已如上所述时间同步,并且包括显示室壁运动和灌注信息。 5, a plurality of film 502 also shows loop movie has been described above, the time synchronization loop, and includes a display wall motion and perfusion information. 如图5所示,室壁运动电影环路、首次通过的灌注电影环路以及MDE图像都可同时进行显示。 5, wall motion film loop, the first loop and the film MDE perfusion images can be displayed simultaneously by. 图5中,基线室壁运动电影环路502、第一剂量室壁运动电影环路504、峰值剂量室壁运动电影环路506、恢复室壁运动电影环路508、 首次通过灌注电影环路510和延迟增强图像512如这里所述同时进行显示。 5, a baseline wall motion film loop 502, a first dose wall motion film loop 504, peak dose wall motion film loop 506, loop 508 recovery wall motion film, the first film by perfusion loop 510 and delayed enhancement image 512 displayed simultaneously as described herein. 图6描述的是按照本发明进一步的实施例的操作。 FIG 6 is described operation of the embodiment according to the present invention further. 如困6所示, 可通过获得用户输入来裁减电影环路基本图,并/或调节基本电影环路图像的对比度、亮度、Y或其它显示等级(模块600 )。 As shown trapped 6, the film may be cut through the loop of FIG substantially obtaining user input, and / or adjust the contrast of the base image film loop, a luminance, Y, or other display level (block 600). 裁减和/或等级调整可自动传播到基本电影环路中剩余的困像以及传播到其它显示或存储的电影环路(模块604 )中。 Reduction and / or level adjustment may be automatically propagated to the base film remaining trapped in the loop, and propagated to other image display or storage of the film loop (block 604). 因此,医师可迅速调整电影环路图像的显示而不必调整每一副图像和/或单个的环路。 Thus, the physician can quickly adjust the displayed movie image loop without having to adjust each of the sub-picture and / or a single loop. 可选择的是,裁减和/或等级信息可存储并与电影环路相关联,电影环路可储存在例如硬盘或其它存储介质上,并在之后恢复,以供显示和/或分析。 Alternatively, the reduction and / or grade information may be stored and associated with the film loop, the loop can be stored on the film, for example, a hard disk or other storage medium, and, after recovery, for display and / or analysis. 存储的电影环路被随后与自动应用的裁减和/或等级信息一起显示。 Stored movies loop is then displayed together with the application of the automatic cuts and / or grade information. 尽管本发明实施例首先参照MRI困像接近实时的评估进行了描述,如借助于本发明公开内容的本领域技术人员所知,MRI图像的评估还可在"离线"或较长的停滞后进行。 Although the embodiments of the present invention Referring first MRI assessment trapped near real time image has been described as means of those skilled in the art of the present disclosure, the MRI image can also be assessed in the "off-line" or longer stagnant . 例如,早先的MRI图像可显示并与当前的MRI图像进行比较,以确定在室壁运动和/或灌注中是否发生了可能由于治疗过程而致的情况改善.因此,本发明不应理解为仅限于采集之后立即评估MRI电影环路图像。 For example, an MRI image may be displayed earlier, and compared with the current MRI image, to determine if there is possible to improve the situation since the treatment caused the wall motion and / or perfusion. Accordingly, the present invention is not to be construed as merely MRI images to assess movie loop immediately after the limited collection. 前文描述了本发明但不作为本发明的限制。 The foregoing description of the present invention but are not construed as limiting the present invention. 尽管对本发明的一些示例性的实施例进行了描述,本领城技术人员容易知道不在实质上偏离本发明的新颖性教导和本发明优点的情况下这些示例性实施例中可进行许多的修改。 Although the case of some exemplary embodiments of the present invention have been described, those skilled in the art readily recognize town do not materially departing from the novel teachings and advantages of the present invention, the present invention these exemplary embodiments, numerous modifications may be made.因此,所有这些修改包括在如权利要求书所限定的本发明的范围之内。
