然而，长期连续/重复地激发梯度线圈可能会损坏梯度线圈，进而可能导致梯度线圈失效，例如，生成降级的梯度磁场并且/或者根本不产生梯度磁场。
Continued/repeated excitation of a gradient coil over an extended period of time, however, may damage the gradient coil, which in turn, may result in failure of the gradient coil, e.g., generation of degraded magnetic gradient fields and/or an inability to generate a magnetic gradient field at all.
通常，梯度线圈的失效导致从MRI程序/扫描获得无用数据。
Typically, failure of a gradient coil results in unusable data from an MRI procedure/scan.
如将理解的那样，许多MRI程序通常是资源密集的。
As will be appreciated, many MRI procedures are often resource intensive.
因此，对于患者和MRI系统操作者例如医院而言，利用未检测到的失效梯度线圈执行MRI程序/扫描通常是很昂贵的。
Thus, executing an MRI procedure/scan with an undetected failed gradient coil is often a costly event for both patients and MRI system operators, e.g., hospitals.
由于各种原因，通常很难并且/或者不能经由手动检查来预测特定梯度线圈何时会失效。
Due to a variety of reasons, it is often difficult and/or impossible to predict when a particular gradient coil will fail via manual inspection.
例如，梯度线圈可能难以手动检查，因为它通常位于/包封在磁体组件中。
For example, gradient coils can be difficult to manually inspect as they are typically located/encased in a magnet assembly.
这样，对梯度线圈的手动检查通常需要使MRI系统离线，即停止使用，这降低了MRI系统对于患者而言的可用性。
As such, manual inspection of a gradient coil typically requires the MRI system to be taken offline, i.e., out of service, which reduces the availability of the MRI system to patients.
另外，由于许多传统的梯度线圈诊断系统在检测/识别指示即将发生的失效的症状方面的能力受到限制，因此对梯度线圈的手动检查可能无法准确地预测梯度线圈的失效。
Further, manual inspection of a gradient coil may not accurately predict failure of the gradient coil as many traditional gradient coil diagnostics systems are limited in their capabilities to detect/recognize symptoms indicative of an impending failure.
虽然存在用于检测失效的梯度线圈的自动方法，但是许多这样的方法仅在梯度线圈发生失效之后才有效。
While automated approaches for detecting a failed gradient coil exist, many such approaches are only effective after failure of the gradient coil has occurred.
另外，此类系统在检测/识别指示即将发生的失效的症状方面的能力上可能受到限制。
Additionally, such systems may be limited in their capabilities to detect/recognize symptoms indicative of an impending failure.
因此，通常需要一种用于监测设置在MRI系统中的梯度线圈的健康状态的改进的系统和方法。

附图示出了所描述的用于监测梯度线圈的健康状态的系统和方法的特定方面。
The drawings illustrate specific aspects of the described systems and methods for monitoring a health status of a gradient coil.
连同以下描述，附图示出并且解释了本文描述的结构原理、方法和原理。
Together with the following description, the drawings demonstrate and explain the principles of the structures, methods, and principles described herein.
本文中公开的一些实施例涉及工业资产，并且更具体地，涉及使用安全的分布式分类账来验证工业数据的系统和方法。
Some embodiments disclosed herein relate to industrial assets and, more particularly, to systems and methods to verify industrial data using a secure, distributed ledger.
最近的技术进步已经导致相对于工业空间的增加的连接性。
Recent technological advancements have resulted in increased connectivity with respect to the industrial space.
随着智能装置和工业互联网以及其他技术的出现，基于大量数据(其中大部分是从互连的传感器收集的数据)，非常快速地改善系统(例如制造厂)和工业资产的运行的能力已经充分地得到了改善。
With the emergence of smart devices and the industrial internet, among other technologies, the ability to improve the operation of systems (e.g., factories) and industrial assets very quickly based on large amounts of data, much of it gathered from interconnected sensors, has improved substantially.
例如，可监控燃气轮机、喷气引擎等的性能以改善性能并避免故障。
For example, the performance of gas turbines, jet engines, etc. may be monitored to improve performance and avoid malfunctions.
然而，这些优点也可能具有不利的后果。
However, these benefits may also have adverse consequences.
例如，未经授权的各方可能利用工业系统中的许多漏洞来破坏工业资产。
For example, numerous vulnerabilities in industrial systems might be utilized by unauthorized parties to compromise the industrial assets.
考虑来自输油管道、水压系统、燃气轮机和其他工业装备的传感器数据，这些数据可能被更改以给出错误的读数或损坏的数据。
Consider sensor data from oil pipelines, water pressure systems, gas turbines, and other industrial equipment that could be altered to give false readings or corrupted data.
这样的更改的结果可能导致自动控制器和人工操作员采取不正确的纠正措施。
The result of such alterations might cause both automatic controllers and human operators to take improper corrective actions.
这些行为可能导致社会的巨大混乱，并增加工厂和制造厂的运营成本。
These actions might lead to substantial confusion in the community as well as increase the operating costs of plants and factories.
为了避免这样的后果，集中式架构可利用存储可用于验证工业数据的散列值的数据库。
To avoid such consequences, a centralized architecture might utilize a database storing hash values that can be used to verify industrial data.
然而，由于所有内容都存储在一个单一的原版拷贝或数据库中，因此，架构中的单个被危及的元素可能会使整个系统面临风险，并且允许对数据进行操作或破坏。
However, because there is a single master copy or database where everything is stored, a single compromised element within the architecture could put the entire system at risk and allow data to be manipulated or corrupted.
因此，期望提供有效且准确地促进工业数据验证的系统和方法。
It would therefore be desirable to provide systems and methods to efficiently and accurately facilitate industrial data verification.
根据一些实施例，系统可以包括具有数据连接件的验证平台，以接收来自工业资产传感器的包括工业资产数据的子集的工业资产数据流。
According to some embodiments, a system may include a verification platform with a data connection to receive a stream of industrial asset data, including a subset of the industrial asset data, from industrial asset sensors.
验证平台可将工业资产数据的子集存储到数据存储器中，该工业资产数据的子集被标记为无效，并将与和元数据组合的工业资产数据的子集的压缩表示相关联的散列值记录在(例如，与区块链技术相关联的)安全的分布式分类账中。
The verification platform may store the subset of industrial asset data into a data store, the subset of industrial asset data being marked as invalid, and record a hash value associated with a compressed representation of the subset of industrial asset data combined with metadata in a secure, distributed ledger (e.g., associated with blockchain technology).
然后，该验证平台可从安全的分布式分类账中接收交易标识符，并且在使用该交易标识符来验证所记录的散列值匹配与元数据组合的工业资产数据的子集的压缩表示的独立创建的版本的散列值之后，将数据存储器中的工业资产数据的子集标记为有效。
The verification platform may then receive a transaction identifier from the secure, distributed ledger and mark the subset of industrial asset data in the data store as being valid after using the transaction identifier to verify that the recorded hash value matches a hash value of an independently created version of the compressed representation of the subset of industrial asset data combined with metadata.
一些实施例包括：用于从工业资产传感器接收包括工业资产数据的子集的工业资产数据流的装置；用于将工业资产数据的子集存储到数据存储器中的装置，该工业资产数据的子集被标记为无效；用于将与和元数据组合的工业资产数据的子集的压缩表示相关联的散列值记录在安全的分布式分类账中装置；用于从安全的分布式分类账中接收交易标识符的装置；以及用于在验证平台处在使用该交易标识符来验证所记录的散列值匹配与元数据组合的工业资产数据的子集的压缩表示的独立创建的版本相关联的散列值之后，将数据存储器中的工业资产数据的子集标记为有效的装置。
Some embodiments comprise: means for receiving a stream of industrial asset data, including a subset of the industrial asset data, from industrial asset sensors; means for storing the subset of industrial asset data into a data store, the subset of industrial asset data being marked as invalid; means for recording a hash value associated with a compressed representation of the subset of industrial asset data combined with metadata in a secure, distributed ledger; means for receiving a transaction identifier from the secure, distributed ledger; and means for marking the subset of industrial asset data in the data store as being valid after using the transaction identifier to verify, at the verification platform, that the recorded hash value matches a hash value associated with an independently created version of the compressed representation of the subset of industrial asset data combined with metadata.
