In cardiology, it is often necessary to acquire more than one type of image to investigate a given clinical problem of a single patient. Images obtained from different imaging modalities are usually recorded and displayed in different orientations, at different positions, and at different scale factors. It is then necessary for the physician to mentally integrate the image information from the different imaging modalities. This phenomenon is particularly true with tomographic imaging techniques that allow complete freedom of the acquisition plane. In particular, when comparing images obtained from ultrasound, computed tomography, magnetic resonance imaging, positron-emission tomography, and single-photon emission computed tomography. The purpose of this article is to propose a standard set of slice orientations that could be easily applied to all modalities. Such common views could greatly facilitate the user's perception of the regional abnormalities observed in the different imaging modalities. This standardization is certainly useful for clinical application but also for every research study that requires a comparative evaluation of the different imaging modalities. Although exact registration of the images from the different modalities requires sophisticated computer programs, the simple reference method in plane positioning proposed here based on plane orientation according to the cardiac geometry can certainly provide a practical and convenient method for the reasonably accurate image registration required for visual comparative studies.
在心脏病学中，通常需要获取不止一种类型的图像来研究单个患者的特定临床问题。从不同成像模态获得的图像通常以不同的方向、在不同的位置以及不同的比例因子进行记录和显示。然后，医生需要在脑海中整合来自不同成像模态的图像信息。这种现象在断层成像技术中尤为明显，因为断层成像技术允许采集平面完全自由。特别是在比较从超声、计算机断层扫描、磁共振成像、正电子发射断层扫描和单光子发射计算机断层扫描获得的图像时。本文的目的是提出一组标准的切片方向，使其能够轻松应用于所有模态。这样的通用视图可以极大地促进用户对在不同成像模态中观察到的局部异常的感知。这种标准化对于临床应用当然有用，对于每一项需要对不同成像模态进行比较评估的研究也很有用。尽管来自不同模态的图像的精确配准需要复杂的计算机程序，但这里提出的基于心脏几何形状的平面方向进行平面定位的简单参考方法，肯定可以为视觉比较研究所需的合理准确的图像配准提供一种实用且方便的方法。
