    • Apparatus and methods are described for use with an input angiogram image of a device inserted inside a portion of subject's body, the angiogram image being acquired in the presence of contrast agent. At least one processor (11) includes background-image-generation functionality (13) configured to generate a background image in which a relative value is assigned to a first pixel with respect to a second pixel, at least partially based upon relative values of surroundings of the first pixel and the surroundings of the second pixel in the input image. Cleaned-image-generation functionality (14) generates a cleaned image in which visibility of the radiopaque portions of the device is increased relative to the input image, by dividing the input image by the background image. Output-generation functionality (15) drives a display (16) to display an output based upon the cleaned image. Other applications are also described.
    • 描述了与插入受试者身体的一部分内的装置的输入血管造影图像一起使用的装置和方法,在存在造影剂的情况下获取血管造影图像。 至少一个处理器(11)包括背景图像生成功能(13),其被配置为生成背景图像,其中相对于第二像素将相对值分配给第一像素,至少部分地基于周围环境的相对值 的第一像素和第二像素的周围。 清洁图像生成功能(14)通过将输入图像除以背景图像来生成其中相对于输入图像增加设备的不透射线部分的可视性的清洁图像。 输出产生功能(15)驱动显示器(16)以基于清洁的图像显示输出。 还描述了其它应用。
