Angiographic image determination method and angiographic image determination device

The embodiment of the invention provides a contrastographic image judgment method and a contrastographic image judgment device. The method includes: acquiring a plurality of first images of a body part injected with a developer; performing a first image pre-processing operation on each first image to obtain a plurality of corresponding second images; obtaining a pixel statistical characteristic of each second image; finding out candidate images based on the pixel statistical characteristics of the second images; and finding out a reference image corresponding to the candidate image from the plurality of first images. 本发明的实施例提供一种造影图像判定方法及造影图像判定装置。所述方法包括：取得经注射显影剂的身体部位的多张第一图像；通过对各第一图像进行第一图像前处理操作取得对应的多张第二图像；取得各第二图像的像素统计特性；基于各第二图像的像素统计特性找出候选图像；以及在所述多个第一图像中找出对应于候选图像的参考图像。
