The use of digital image resampling can be highly suitable for diagnostic radiology. It can be applied not only to obtain zoom effects but also to solve various problems related to the comparison of images of different origin (NMR, CT, NM). The mathematical approach to this kind of algorithm, based on rational assumptions, can be very wide and diversified. In this work the principles of the stochastic and of the analytical methods have been analyzed. In particular, a complete mathematical treatment of the integral analytical methods, which are both the most theoretically interesting and analytically complex, has been performed. The practice of these techniques has to be determined each time from the analysis of the specific problem to which they are to be applied in the routine, and after a retrospective analysis of the results obtained.
数字图像重采样的应用非常适合于诊断放射学。它不仅可以用于获得缩放效果，还可以用于解决与不同来源图像（核磁共振成像、计算机断层扫描、核医学成像）比较相关的各种问题。基于合理假设的此类算法的数学方法可以非常广泛和多样。在这项工作中，分析了随机方法和解析方法的原理。特别是，对积分解析方法进行了完整的数学处理，这些方法在理论上最具趣味性且分析起来较为复杂。这些技术的实际应用每次都必须根据对其在日常工作中应用的具体问题的分析以及对所得结果的回顾性分析来确定。
