Abstract
Methods and systems are provided for reconstructing images with a tailored image texture. In one embodiment, a method comprises acquiring projection data, and reconstructing an image from the projection data with a desired image texture. In this way, iterative image reconstruction techniques may be used to substantially reduce image noise, thereby enabling a reduction in injected contrast and/or radiation dose, while preserving an image texture familiar from analytic image reconstruction techniques.

13. A method, comprising:
-
acquiring projection data of a subject; iteratively reconstructing a first image from the projection data; analytically reconstructing a second image from the projection data; and generating an image with a desired image texture from the first image and the second image, the desired image texture of the image derived from the second image. - View Dependent Claims (14, 15)

16. A system, comprising:
-
an x-ray source that emits a beam of x-rays toward an object to be imaged; a detector that receives the x-rays attenuated by the object; a data acquisition system (DAS) operably connected to the detector; and a computing device operably connected to the DAS and configured with executable instructions in non-transitory memory that when executed cause the computing device to; acquire, via the DAS, projection data of the object; and reconstruct, from the projection data, an image with a desired image texture. - View Dependent Claims (17, 18, 19, 20)
