Method for representing two-dimensional projection images and objects corresponding thereto

A computer program loadable to a computer for performing a representation method for two-dimensional projection images of an examination object showing a variation of a distribution of a contrast medium over time in the examination object, comprising:

• a computer subroutine that is stored on a non-transitory computer-readable medium, wherein said computer subroutine is configured to:
• subdivide a two-dimensional project image that is to be displayed from the two-dimensional projection images into a grid pattern having a plurality of parcels in a perfusion region of the examination object, wherein each of the parcels has a predetermined shape and each parcel includes a plurality of pixels,
• determine a characteristic value for each parcel in the perfusion region,
• determine a projection color for the each parcel based on the characteristic value,
• assign the projection color to the each parcel, and
• represent the each parcel by the assigned projection color.

A medical examination device for representing two-dimensional projection images of an examination object showing a variation of a distribution of a contrast medium over time in the examination object, comprising:

• an image recording device that records the two-dimensional projection images;
• and
• a computer that:
• subdivides a two-dimensional project image that is to be displayed from the two-dimensional projection images into a grid pattern having a plurality of parcels in a perfusion region of the examination object, wherein each of the parcels has a predeteimined shape and each parcel includes a plurality of pixels,
• determines a characteristic value for each parcel in the perfusion region,
• determines a projection color for the each parcel based on the characteristic value,
• assigns the projection color to the each parcel, and
• represents the each parcel by the assigned projection color.
