在人脑MRI采集期间，所得到的图像由2D切片形成。然后必须对齐并重建切片，以提供脑体积的三维（3D）可视化。在这项工作中，我们提出了一个集成系统的注册离子和3D重建的DICOM MRI图像和病变的大脑获得多发性硬化症（MS）的主题在两个不同的时间间隔（时间0（T0）和时间1（T1））。该系统有助于MS疾病发展的随访，并将帮助医生准确管理疾病的随访。它涉及6个阶段的分析（预处理，病变分割，配准，3D重建，体积估计和方法评估），以及该方法的模块定量评估。基于一个MRI体模和一个大脑DICOM MRI图像对系统进行评价。所提出的配准和重建（- / -）方法对体模和MRI图像的准确率分别为78.5%/97.2%和95.4%/95.8%。这些初步结果提供了证据，该系统可以在未来的临床实践中应用。
During a human brain MRI acquisition the resulting image is formed out of 2D slices. The slices must then be aligned and reconstructed to provide a 3-dimensional (3D) visualization of the brain volume. We propose in this work, an integrated system for the register ion and 3D reconstruction of DICOM MRI images and lesions of the brain acquired from multiple sclerosis (MS) subjects at two different time intervals (time 0 (T0) and time 1 (T1)). The system facilitates the follow up of the MS disease development and will aid the doctor to accurately manage the follow up of the disease. It involves a 6-stage analysis (preprocessing, lesion segmentation, registration, 3D reconstruction, volume estimation and method evaluation), as well as module quantitative evaluation of the method. The system was evaluated based on one MRI phantom and one DICOM MRI image of the brain. The accuracy of the proposed registration and reconstruction (- / -) method was 78.5%/97.2% and 95.4%/95.8% for the phantom and the MRI images respectively. These preliminary results provide evidence that the proposed system could be applied in future in the clinical practice.
