EIDORS is an open source software suite for image reconstruction in electrical impedance tomography and diffuse optical tomography, designed to facilitate collaboration, testing and new research in these fields. This paper describes recent work to redesign the software structure in order to simplify its use and provide a uniform interface, permitting easier modification and customization. We describe the key features of this software, followed by examples of its use. One general issue with inverse problem software is the difficulty of correctly implementing algorithms and the consequent ease with which subtle numerical bugs can be inadvertently introduced. EIDORS helps with this issue, by allowing sharing and reuse of well-documented and debugged software. On the other hand, since EIDORS is designed to facilitate use by non-specialists, its use may inadvertently result in such numerical errors. In order to address this issue, we develop a list of ways in which such errors with inverse problems (which we refer to as 'cheats') may occur. Our hope is that such an overview may assist authors of software to avoid such implementation issues.
EIDORS是一个用于电阻抗断层成像和扩散光学断层成像中图像重建的开源软件套件，旨在促进这些领域的合作、测试和新研究。本文描述了最近为重新设计软件结构所做的工作，以便简化其使用并提供统一的接口，从而更容易进行修改和定制。我们描述了该软件的关键特性，随后是其使用示例。反问题软件的一个普遍问题是正确实现算法的难度以及随之而来的不经意间引入细微数值错误的容易程度。EIDORS通过允许共享和重用文档完善且经过调试的软件来帮助解决这个问题。另一方面，由于EIDORS旨在方便非专业人员使用，其使用可能会不经意地导致此类数值错误。为了解决这个问题，我们列出了反问题中此类错误（我们称之为“作弊”）可能出现的一系列方式。我们希望这样的概述可以帮助软件作者避免此类实现问题。
