The invention discloses a CT image hardening phenomenon processing method and device, electronic equipment and a medium. The method comprises the following steps: acquiring an original CT scanning image; performing gray processing on the original CT scanning image to obtain a gray image; performing frequency domain transformation on the grayscale image to obtain an original frequency spectrum image; performing high-pass filtering processing on the original frequency spectrum image to obtain a corrected frequency spectrum image; and performing inverse transformation of the frequency domain transformation on the corrected frequency spectrum image to obtain a hardened corrected CT image. According to the technical scheme, the problem that the CT scanning image is poor in image quality due to the hardening phenomenon can be solved, and the image quality is improved. 本发明公开了一种CT图像硬化现象处理方法、装置、电子设备及介质。该方法包括：获取原始CT扫描图像；对所述原始CT扫描图像进行灰度处理，得到灰度图像；对所述灰度图像进行频域变换，得到原始频谱图像；对所述原始频谱图像进行高通滤波处理，得到校正频谱图像；对所述校正频谱图像进行所述频域变换的逆变换，得到硬
