In the field of medicine, photogrammetry has played for long time a marginal role due to the significant amount of work required that made it impractical for an extended medical use. Developments in digital photogrammetry occurred in the recent years, that have steadily increased the interest and application of this technique. The present study aims to compare photogrammetry reconstruction of heart with computed tomography (CT) as a reference. The photogrammetric reconstructions of digital images from ECG imaging derived images were performed. In particular, the ventricles of 15 patients with Brugada syndrome were reconstructed by using the free Zephyr Lite software. In order to evaluate the accuracy of the technique, measurements on the reconstructions were compared to patient-specific CT scan imported in ECG imaging software UZBCIT. The results showed that digital photogrammetry in the context of ventricle reconstruction is feasible. The photogrammetric derived measurements of ventricles were not statistically different from CT scan measurements. Furthermore, the analysis showed high correlation of photogrammetry reconstructions with CT scan and a correlation coefficient close to 1. It is possible to reproduce digital objects by photogrammetry if the process described in this study is performed. The reconstruction of the ventricles from CT scan was very close to the values of the respective photogrammetric reconstruction.
在医学领域，由于所需工作量巨大，使得摄影测量法长期以来一直处于边缘地位，无法广泛应用于医学领域。近年来，数字摄影测量技术不断发展，这使得人们对该技术的兴趣和应用稳步增加。本研究旨在将心脏的摄影测量重建与计算机断层扫描（CT）作为参考进行比较。对源自心电图成像的数字图像进行了摄影测量重建。具体而言，使用免费的Zephyr Lite软件对15例Brugada综合征患者的心室进行了重建。为了评估该技术的准确性，将重建后的测量结果与导入心电图成像软件UZBCIT中的患者特异性CT扫描结果进行了比较。结果表明，在心室重建方面，数字摄影测量法是可行的。摄影测量得出的心室测量结果与CT扫描测量结果在统计学上没有差异。此外，分析表明摄影测量重建与CT扫描具有高度相关性，相关系数接近1。如果执行本研究中描述的过程，就可以通过摄影测量法再现数字对象。从CT扫描重建的心室与相应的摄影测量重建值非常接近。
