Method for determining a resultant image, computer program, machine-readable data carrier and imaging device

1. A method for determining and outputting a resultant image, comprising:

controlling at least one imaging device to record a plurality of images of a region under examination at different times, wherein the at least one imaging device comprises at least one of a magnetic resonance imaging (MRI) device, a computed tomography (CT) device, and an X-ray device;

deriving anatomical information from at least one of the plurality of images;

deriving flow information relating to blood flow from the at least one of the plurality of images;

determining a resultant image in which the derived anatomical information and the derived flow information are combined, wherein

an intensity-dependent fenestration assigns gray-scale values to pixels of the resultant image in accordance with the derived anatomical information,

a time-dependent fenestration assigns chromaticities to the pixels in accordance with the derived flow information, wherein the time-dependent fenestration is performed such that at least one of (i) a maximum chromaticity luminance for the pixels is the same and (ii) a maximum color saturation for the pixels is the same, and

the gray-scale values and the chromaticities are assigned independently of one another; and

outputting the resultant image to a display device.

2. The method of claim 1 , wherein the recording of at least a part of the plurality of images is contrast-medium supported.

3. The method of claim 1 , wherein the anatomical information is derived in that a first projection is performed via a plurality of the images recorded at different times.

4. The method of claim 1 , wherein the flow information is derived based on a physical model.

5. The method of claim 1 , wherein at least one of gray scale for the intensity-dependent fenestration and color scale for the time-dependent fenestration is prespecifiable.

6. The method of claim 5 , wherein a section of the output resultant image is graphically displayed on the display device and is selectable, wherein at least one of the gray scale and the color scale are dependent upon the section selected.

7. The method of claim 1 , wherein:

each of the images are spatially three-dimensional images, wherein the anatomical information and the flow information are both embodied as spatially three-dimensional; and

the resultant image is a spatially two-dimensional image, wherein

the intensity-dependent fenestration is performed such that the gray-scale values are assigned to the pixels in accordance with the derived anatomical information projected along a spatial direction, and

the time-dependent fenestration is performed such that the chromaticities are assigned to the pixels in accordance with the derived flow information projected along the spatial direction.

8. A non-transitory computer readable medium comprising program code for performing the method of claim 1 when the program code is executed on a computer.

9. A non-transitory machine-readable data carrier, storing computer program code, for performing the method of claim 1 when the computer program code is executed on a computer.

10. An imaging device, comprising:

a computer to control the imaging device, wherein the imaging device comprises at least one of a magnetic resonance imaging (MRI) device, a computed tomography (CT) device, and an X-ray device, wherein, by sending commands to the imaging device, the computer causes the imaging device to at least,

record a plurality of images of a region under examination at different times;

derive anatomical information from at least one of the plurality of images;

derive flow information relating to blood flow from the at least one of the plurality of images;

determine a resultant image in which the derived anatomical information and the derived flow information are combined, wherein

an intensity-dependent fenestration assigns gray-scale values to pixels of the resultant image in accordance with the derived anatomical information,

a time-dependent fenestration assigns chromaticities to the pixels in accordance with the derived flow information, wherein the time-dependent fenestration is performed such that at least one of (i) a maximum chromaticity luminance for the pixels is the same and (ii) a maximum color saturation for the pixels is the same, and

the gray-scale values and the chromaticities are assigned independently of one another; and

output the resultant image to a display device.

at least one of gray scale for the intensity-dependent fenestration and color scale for the time-dependent fenestration is prespecifiable; and

a section of the output resultant image is graphically displayed on the display device and is selectable, wherein at least one of the gray scale and the color scale are dependent upon the section selected.

12. The imaging device of claim 10 , wherein the recording of at least a part of the plurality of images is contrast-medium supported.

13. The imaging device of claim 10 , wherein the anatomical information is derived in that a first projection is performed via a plurality of the images recorded at different times.

14. The imaging device of claim 10 , wherein the flow information is derived based on a physical model.

15. The imaging device of claim 10 , wherein:

each of the images are spatially three-dimensional images, wherein the anatomical information and the flow information are both embodied as spatially three-dimensional; and

the resultant image is a spatially two-dimensional image, wherein

the intensity-dependent fenestration is performed such that the gray-scale values are assigned to the pixels in accordance with the derived anatomical information projected along a spatial direction, and

the time-dependent fenestration is performed such that the chromaticities are assigned to the pixels in accordance with the derived flow information projected along the spatial direction.
