Method and apparatus for generating a functional data set of a perfused region of the human or animal body

A method for generating a functional data set of a perfused region of a human or animal body, comprising:

• recording first two images of the perfused region at different times before and after an injection of an contrast agent into a first artery supplying the region;
• supplying a first image data set comprising the first two images;
• recording second two images of the perfused region at different times before and after an injection of the contrast agent into a second artery supplying the region;
• supplying a second image data set comprising the second two images;
• generating a first functional data set by pixel-based calculation of a first perfusion parameter from the first image data set;
• and
• generating a second functional data set by pixel-based calculation of a second perfusion parameter from the second image data set.

A method for generating at least one functional data set of a perfused region of a human or animal body, comprising:

• recording first two images of the perfused region at different times before and after an injection of an contrast agent into a first artery supplying the region;
• supplying a first image data set comprising the first two images;
• recording second two images of the perfused region at different times before and after an injection of the contrast agent into a second artery supplying the region;
• supplying a second image data set comprising the second two images;
• linking the first and the second image data sets to form an overall image data set;
• and
• generating an overall functional data set by pixel-based calculation of a perfusion parameter from the overall image data set.

An apparatus generating at least one functional data set of a perfused region of a human or animal body, comprising:

• an image recording system for:
• recording first two images of the perfused region at different times before and after an injection of an contrast agent into a first artery supplying the region;
• supplying a first image data set comprising the first two images;
• recording second two images of the perfused region at different times before and after an injection of the contrast agent into a second artery supplying the region;
• and
• supplying a second image data set comprising the second two images;
• a data storage unit for storing the first and the second image data sets;
• a computation device for generating functional data sets by pixel-based calculation of a perfusion parameter from the first and the second image data sets;
• and
• a screen for displaying the functional data sets.
