Spect System(光谱系统)研究综述
Spect System 光谱系统 - Mutual compatibility is demonstrated along with imaging performance that is comparable with other non-MR micro-SPECT systems: 0. [1] SPECT systems using pinhole apertures permit radiolabelled molecular spatial resolution, good energy resolution, and high sensitivity are required. [2] Following a presentation of the framework, we provide examples and interactional excerpts drawn from a recent project aimed at helping adolescent and university learners of English understand the tense-aspect system and employ it to regulate their use of the language in writing. [3] The INSERT scanner was constructed under the initial project, but its performance was not fully evaluated; here we have reconstructed the first images on the SPECT system. [4] It was also shown that MBF can be obtained with CZT-based SPECT systems having dynamic imaging capability. [5] The aim of this study is to optimize a SPECT system using Monte Carlo method for faster verification of spent fuel assembly than the conventional system. [6] The interaction of morphology with syntax also figures in several articles, and the role of semantics (in terms of time reference and aspect systems). [7] This study addresses how well Indonesian second language learners of English apply the English tense-aspect system. [8] We introduce a generic analytic simulation and image reconstruction software platform for multi-pinhole (MPH) SPECT systems. [9] DTMs are the traces left behind by a tool or process on a suspect system which can help to determine what malicious behaviour has occurred on a device. [10] This article explores to what extent digressions from chronology are attributable to differences in grammatical aspect systems. [11] Finally, cross-correlation coefficients were calculated to better identify the features that could play an important role in assessing quality assurance procedures performed on SPECT systems. [12] However, military operators are normally trained to trust, rather than suspect systems. [13] These artifacts are persistent in nature and are retained even after the system has been shut down and the information they contain may assist in carrying out forensic analysis on a suspect system. [14] ResultsIn both patient groups, there was no significant difference between resting MBF values measured with RRG-SPECT and CZT-SPECT systems (P = 0. [15] The remainder of the model determines the aspect system of the examination. [16] This study is an attempt to investigate the acquisition of translation competence of the English tense and aspect system by Behdini learners who are students at the Translation Department at the College of Languages in the University of Duhok. [17] The purpose of the paper is to explore the aspect system in Thali, a language spoken in Thal region, including district Layya, Bhakar and neighboring areas of Jhang, in Punjab province by a large number of people. [18] Accordingly, this quasi-experimental compared the effects of two pedagogical frameworks, namely Systemic-Theoretical Instruction (STI), derived from Vygotsky’s ideas and proposed by Gal’perin and discovery learning (DL), derived from Piaget’s ideas mainly proposed by Bruner, on learning English tense-aspect system. [19] Contrary to conventional A-SPECT systems, majority of the contemporary PET systems performing cardiac imaging are equipped with list mode gating that allow for editing of gating data. [20]相互兼容性以及与其他非 MR micro-SPECT 系统相媲美的成像性能：0。 [1] 使用针孔孔径的 SPECT 系统允许放射性标记的分子空间分辨率、良好的能量分辨率和高灵敏度是必需的。 [2] 在介绍了该框架之后，我们提供了从最近的一个项目中提取的示例和互动摘录，该项目旨在帮助青少年和大学英语学习者理解时态系统，并利用它来规范他们在写作中对语言的使用。 [3] INSERT 扫描仪是在初始项目下构建的，但其性能并未得到充分评估；在这里，我们已经在 SPECT 系统上重建了第一张图像。 [4] 还表明，MBF 可以通过具有动态成像能力的基于 CZT 的 SPECT 系统获得。 [5] 本研究的目的是优化使用蒙特卡罗方法的 SPECT 系统，以便比传统系统更快地验证乏燃料组件。 [6] 形态与句法的相互作用也在几篇文章中有所体现，以及语义的作用（在时间参考和方面系统方面）。 [7] 本研究探讨了英语的印度尼西亚第二语言学习者如何应用英语时态系统。 [8] 我们介绍了用于多针孔 (MPH) SPECT 系统的通用分析模拟和图像重建软件平台。 [9] DTM 是工具或进程在可疑系统上留下的痕迹，可以帮助确定设备上发生了哪些恶意行为。 [10] 本文探讨了在多大程度上偏离年表可归因于语法方面系统的差异。 [11] 最后，计算了互相关系数，以更好地识别可以在评估 SPECT 系统上执行的质量保证程序中发挥重要作用的特征。 [12] 然而，军事操作员通常被训练去信任而不是怀疑系统。 [13] 这些工件本质上是持久的，即使在系统关闭后也会保留，它们包含的信息可能有助于对可疑系统进行取证分析。 [14] 结果在两组患者中，用 RRG-SPECT 和 CZT-SPECT 系统测量的静息 MBF 值之间没有显着差异（P = 0. [15] 模型的其余部分决定了考试的方面系统。 [16] 本研究旨在调查杜霍克大学语言学院翻译系的 Behdini 学习者对英语时态和体态系统翻译能力的习得情况。 [17] 本文的目的是探索塔利语的方位系统，塔利语是一种在旁遮普省大量人口使用的语言，包括莱亚区、巴卡尔区和Jhang邻近地区。 [18] 因此，这个准实验比较了两种教学框架的效果，即系统理论教学（STI），源自 Vygotsky 的想法并由 Gal'perin 提出，以及发现学习（DL），源自皮亚杰的主要由 Bruner 提出的想法，学习英语时态系统。 [19] 与传统的 A-SPECT 系统相反，大多数执行心脏成像的当代 PET 系统都配备了允许编辑门控数据的列表模式门控。 [20]
cadmium zinc telluride 碲化镉锌
Although the presence of 99mTc-sestamibi/123I-BMIPP-mismatch, the reverse redistribution (RR) of 99mTc-sestamibi and RR of 123I-BMIPP in patients with acute myocardial infarction (AMI) are known to significant markers for predicting the improvement of LV wall motion in the infarcted territory in chronic phase, few studies were performed to analyze them by simultaneous dual-isotope imaging using cadmium-zinc-telluride (CZT) SPECT system. [1] BackgroundWe performed a meta-analysis to compare the diagnostic performance of conventional SPECT (C-SPECT) and cadmium-zinc-telluride (CZT)-SPECT systems in detecting angiographically proven coronary artery disease (CAD). [2] Recently, the emergence of cadmium-zinc-telluride (CZT) SPECT systems enabled the acquisition of images with a higher number of counts, higher quality images, ultrafast acquisitions, dose reduction, and similar diagnostic accuracy using the same radiotracers that are used for conventional SPECT MPI studies. [3] We compared the performance of conventional (C)-SPECT and cadmium-zinc-telluride (CZT)-SPECT systems in women with low-intermediate likelihood of coronary artery disease (CAD). [4]尽管存在 99mTc-sestamibi/123I-BMIPP-错配，但在急性心肌梗死 (AMI) 患者中，99mTc-sestamibi 的反向再分布 (RR) 和 123I-BMIPP 的 RR 是预测 LV 改善的重要标志物。在慢性期梗塞区域的壁运动，很少有研究通过使用镉-锌-碲化物 (CZT) SPECT 系统的同时双同位素成像来分析它们。 [1] 背景我们进行了一项荟萃分析，以比较常规 SPECT (C-SPECT) 和镉-锌-碲化物 (CZT)-SPECT 系统在检测经血管造影证实的冠状动脉疾病 (CAD) 中的诊断性能。 [2] 最近，镉-锌-碲化物 (CZT) SPECT 系统的出现使得能够使用与常规放射性示踪剂相同的放射性示踪剂采集具有更高计数、更高质量图像、超快采集、剂量减少和类似诊断准确性的图像。 SPECT MPI 研究。 [3] nan [4]
Cardiac Spect System 心脏光谱系统
PURPOSE Dedicated cardiac SPECT systems do not typically include an integrated CT scanner and thus attenuation correction requires registration of separately acquired transmission scans. [1] Dedicated cardiac SPECT systems have invaluable efficacy in the evaluation and risk stratification of patients with known or suspected cardiovascular disease. [2] Purpose: Dey group proposed a high sensitivity Cardiac SPECT system using hemi-ellipsoid detectors with pinhole collimation. [3] In this work, we introduced the ProSPECT system, a dedicated cardiac SPECT system with open-gantry design. [4]目的 专用心脏 SPECT 系统通常不包括集成的 CT 扫描仪，因此衰减校正需要对单独采集的透射扫描进行配准。 [1] 专用心脏 SPECT 系统在对已知或疑似心血管疾病患者进行评估和风险分层方面具有不可估量的功效。 [2] 目的：Dey 小组提出了一种高灵敏度的心脏 SPECT 系统，该系统使用具有针孔准直的半椭球体探测器。 [3] 在这项工作中，我们介绍了 ProSPECT 系统，这是一种具有开放式龙门设计的专用心脏 SPECT 系统。 [4]
Clinical Spect System 临床光谱系统
We tested our approach on a high-resolution multi-pinhole prototype clinical SPECT system in a Monte Carlo simulation study. [1] Therefore, we propose a SPECT-only-based strategy for μ map estimation that we apply to a stationary multi-pinhole clinical SPECT system (G-SPECT-I) for 99mTc-HMPAO brain perfusion imaging. [2] The challenges facing the majority of clinical SPECT systems are low sensitivity, poor resolution, and the relatively high radiation dose to the patient. [3]我们在蒙特卡罗模拟研究中测试了我们在高分辨率多针孔原型临床 SPECT 系统上的方法。 [1] 因此，我们提出了一种基于 SPECT 的 μ 图估计策略，我们将其应用于用于 99mTc-HMPAO 脑灌注成像的固定多针孔临床 SPECT 系统 (G-SPECT-I)。 [2] nan [3]
Imaging Spect System
Inspection of imaging SPECT system performance was controlled by Quality Control (QC) regularly. [1] We report our investigation of system designs and 3D reconstruction for a dedicated brain-imaging SPECT system using multiple square or square and hexagonal detector modules. [2]成像 SPECT 系统性能的检查由质量控制 (QC) 定期控制。 [1] 我们报告了我们对使用多个方形或方形和六边形探测器模块的专用脑成像 SPECT 系统的系统设计和 3D 重建的调查。 [2]
Pinhole Spect System
For this purpose, we developed a Monte Carlo simulation model of a preclinical state-of-the-art multi-pinhole SPECT system, the NanoSPECT/CTPLUS, with emphasis on high accuracy for multi-isotope experiments operating near the system range limits. [1] We developed an algorithm to compensate the head motion in multi-pinhole SPECT systems within a statistical iterative image reconstruction algorithm. [2]为此，我们开发了临床前最先进的多针孔 SPECT 系统 NanoSPECT/CTPLUS 的蒙特卡罗模拟模型，重点是在系统范围限制附近运行的多同位素实验的高精度。 [1] nan [2]
