A computed tomography (CT) image display system () includes a mapping unit (), which receives reconstructed volumetric image data () of a subject with values in Hounsfield Units (HU), and a set of reference settings (), adjusts the set of reference settings () to an adjusted set of reference settings () according to a pixel-value distribution analysis of the HU values selected according to the reference settings (), and maps the values in HU to gray scale values according to the adjusted reference settings ().

Computed tomography visualization adjustment

A method includes processing projection data with a first reconstruction algorithm and reconstructing first reconstructed volumetric image data, wherein the first reconstructed volumetric image data has a first 3D noise function. The method further includes processing the same projection data with a second different reconstruction algorithm and reconstructing second reconstructed volumetric image data, wherein the second reconstructed volumetric image data has a second 3D noise function, which is different from the first 3D noise function. The method further includes visually presenting the first or the second reconstructed volumetric image data in a main viewport. The method further includes visually presenting a sub-portion the other of the first or the second reconstructed volumetric image data in a region of interest overlaid over a sub-portion of the main viewport.

Reconstructed image data visualization

A method includes determining a low contrast detectability of a scan and generating an image quality index based on the determined low contrast detectability. Another method includes identifying an image quality index of interest, identifying an acquisition and/or reconstruction parameter based on the image quality index and a pre-determined mapping between image quality indexes and acquisition parameter and reconstruction parameters, and displaying the identified acquisition and/or the reconstruction parameter. A system () includes a metric determiner () that determines a first image quality index for a scan based on at least one of a low contrast detectability of the scan or a project domain noise of the scan, and/or a parameter recommender () that recommends at least one of an acquisition or a reconstruction parameter for a scan based on a second image quality index, and a display () that visually presents the first or second image quality index.
