肿瘤位置通常通过参考磁共振（MR）图像来描绘。然而，MR图像具有不能完全校正的几何失真。本研究的目的是调查定量不可纠正的错误[残留误差（RE）]与科学图像分析的开源插件的使用。RE值由Fiji计算，其通过Image J图像处理软件增强。使用科学图像分析开源插件获得的结果与使用商业软件获得的结果一致。获得每个设施和设备的详细几何失真数据可以促进安全治疗，因为MR成像中的均匀磁场随设备和时间而变化。因此，使用开源插件进行科学图像分析可能是评估MR成像系统RE的准确有效的技术。
Tumor locations are commonly delineated by referring to magnetic resonance (MR) images. However, MR images have geometric distortions that cannot be completely corrected. This study aimed to investigate quantitatively uncorrectable error [residual error (RE)] with the use of an open-source plugin for scientific image analysis. The RE values were calculated by Fiji, which was enhanced by Image J image processing software. The results obtained with the open-source plugin for scientific image analysis agreed with the results obtained with the commercially available software. Obtaining detailed geometric distortion data for each facility and device could facilitate safe treatment because the homogeneous magnetic field in MR imaging varies across devices and over time. Therefore, using an open-source plugin for scientific image analysis may be an accurate and effective technique for evaluating the RE of MR imaging systems.
