摘要
插值广泛应用于医学成像和图像多维重建中。本文首先对传统插值方法中基于形状的插值和弹性匹配插值作了比较深入的介绍 ,然后分析了旋转扫描超声心脏图像插值方法的特点、难点和研究现状 ,论述了插值和匹配的关系 ,分析表明准确的旋转扫描插值方法应该是基于匹配的方法 。
Image interpolation techniques were widely applied in medical imaging for image generation and post processing. Firstly, traditional interpolation methods were listed out in the details of shape based interpolation and dynamic elastic registration interpolation. Secondly, the characteristics, development and problems in interpolation of rotary scanning ultrasonic cardiac images were analyzed. The relation between interpolation and registration was stated. The analysis indicated that excellent methods in rotary scanning interpolation should be registration based methods. At last, several evaluation methods about images interpolation were discussed.
