Electron paramagnetic resonance oxygen imaging, EPROI, is established as a method for quantitative oxygen imaging. For tissue identification, in vivo oxygen images need to be paired with higher tissue contrast images such as MRI, CT, or ultrasound. All these images are acquired using different instruments and a method to represent them in a common coordinate frame, image registration, is required. Registered EPROI can be used for directing cancer treatment or validation of other oxygen-related imaging methods such as PET or histological staining. We present an image registration and analysis system comprised of two components: an animal bed with registration guides and an ArbuzGUI MATLAB toolbox developed in our laboratory. The toolbox includes components for image registration, segmentation, and oxygen analysis.

电子顺磁共振氧成像 (EPROI) 是一种定量氧成像方法。对于组织识别，体内氧气图像需要与更高的组织对比度图像（如 MRI、CT 或超声）配对。所有这些图像都是使用不同的仪器获取的，并且需要一种在公共坐标系中表示它们的方法，即图像配准。注册的 EPROI 可用于指导癌症治疗或验证其他与氧气相关的成像方法，如 PET 或组织学染色。我们提出了一个图像配准和分析系统，由两个组件组成：带有配准指南的动物床和我们实验室开发的 ArbuzGUI MATLAB 工具箱。该工具箱包括用于图像配准、分割和氧气分析的组件。
