The application of multimodal image registration to various medical applications has been investigated. Image fusion involving 3D thermal and MRI/CT images allows the extraction of both functional and anatomical information, which may become a powerful tool to aid in clinical diagnoses. This paper presents innovations at the image fusion methodology, which currently requires that both imaging modalities are represented and visualized at the same 3D viewing projection. The proposed solution is based and compared with two different viewing projections: orthogonal and perspective. The methodology requires that the thermographic images (or photographs) are visualized in the orthogonal view, in order to match with the 2D projected images (using range images) from MRI/CT. The results obtained have shown significant improvements in the 3D thermal models, when compared and evaluated with the perspective approach. This allowed the generation of more accurate 3D models, which match both the geometry and texture (functional temperature information). Since it is desirable to combine or unify more than one imaging modality, these 3D multimodal models may have a strong impact in many clinical applications.
多模态图像配准在各种医学应用中的应用已得到研究。涉及三维热成像与磁共振成像/计算机断层扫描图像的图像融合能够提取功能和解剖信息，这可能成为辅助临床诊断的有力工具。本文介绍了图像融合方法的创新之处，目前该方法要求两种成像模态在相同的三维观察投影中呈现和可视化。所提出的解决方案基于两种不同的观察投影：正交投影和透视投影，并进行了比较。该方法要求热成像图像（或照片）在正交视图中可视化，以便与磁共振成像/计算机断层扫描的二维投影图像（使用距离图像）相匹配。与透视法相比和评估时，所获得的结果表明三维热模型有显著改进。这使得能够生成更精确的三维模型，该模型在几何形状和纹理（功能温度信息）方面都能匹配。由于期望将不止一种成像模态进行组合或统一，这些三维多模态模型可能会对许多临床应用产生重大影响。
