The invention relates to an image generation apparatus for generating an image of an object. An image providing unit (11, 16) provides a first image of the object and a second image of the object, wherein the first image has a smaller noise level than the second image. A display window providing unit (12) provides a display window being indicative of the range of image values shown on a display (14), and a combining unit (13) generates a combination image by combining the first image and the second image depending on the window width of the provided display window. This allows considering the influence of the display window on the noise appearance. Thus, by taking into account the first image and the second image having different noise levels and the provided display window, a combined image can be generated, which has an improved noise appearance.
An image generation apparatus for generating an image of an object, the image generation apparatus comprising:
The image generation apparatus as defined in claim I, wherein the combining unit adapted to combine the first image and the second image such that the amount of the first image decreases and the amount of the second image increases with increasing window width of the display window for window widths being smaller than a third threshold window width, and to combine the first image and the second image such that the amount of the first image increases and the amount of the second image decreases with increasing window width of the display window for window widths being equal to or larger than the third threshold window width.
An image generation method fir generating an image of an object, the image generation method comprising:
