Abstract

本申请实施例提供了一种图像配准方法、图像配准装置、放疗设备和计算机可读存储介质，该图像配准方法包括通过获取第一图像和第二图像，分别在第一图像和第二图像中识别待配准区域，并生成仅包含待配准区域的第一待配准图像和第二待配准图像，进而对第一待配准图像和第二待配准图像进行配准。由于第一待配准图像和第二待配准图像中仅包含待配准区域，基于第一待配准图像和第二待配准图像进行配准，可以避免在直接基于第一图像和第二图像进行配准时第一图像和第二图像中的其他区域对待配准区域的干扰，提高了配准精度。同时，由于基于第一待配准图像和第二待配准图像进行配准时使用的数据量较少，节约了配准的时间，提高了配准的速度。
