Generation of artificial contrast-enhanced radiological images

A computer system comprising

• a processor;
• and
• a memory that stores an application program configured to perform an operation when executed by the processor, said operation comprising:
• receiving a first representation, the first representation representing an examination region of an examination object without contrast agent or after administration of a first amount of a contrast agent,
• receiving a second representation, the second representation representing the examination region of the examination object after administration of a second amount of the contrast agent, the second amount being larger than the first amount,
• generating a third representation on the basis of the first representation and the second representation, the generating the third representation comprising subtracting the first representation from the second representation,
• generating a fourth representation, the generating the fourth representation comprising adding the third representation to the first representation α times, α being a positive or negative real number,
• outputting and/or storing the fourth representation and/or transmitting the fourth representation to a separate computer system.

A computer program product comprising a data carrier on which a computer program is stored, the computer program being loadable into a working memory of a computer system, where it causes the computer system to execute the following steps:

• receiving a first representation, the first representation representing an examination region of an examination object without contrast agent or after administration of a first amount of a contrast agent,
• receiving a second representation, the second representation representing the examination region of the examination object after administration of a second amount of the contrast agent, the second amount being larger than the first amount,
• generating a third representation on the basis of the first representation and the second representation, the generating the third representation comprising subtracting the first representation from the second representation,
• generating a fourth representation, the generating the fourth representation comprising adding the third representation to the first representation α times, α being a positive or negative real number,
• outputting and/or storing the fourth representation and/or transmitting the fourth representation to a separate computer system.

The use of a contrast agent in a radiological examination method comprising:

• receiving or generating a first representation, the first representation representing an examination region of an examination object without the contrast agent or after administration of a first amount of the contrast agent,
• receiving or generating a second representation, the second representation representing the examination region of the examination object after administration of a second amount of the contrast agent, the second amount being larger than the first amount,
• generating a third representation on the basis of the first representation and the second representation, the generating the third representation comprising subtracting the first representation from the second representation,
• generating a fourth representation, the generating the fourth representation comprising adding the third representation to the first representation α times, α being a positive or negative real number,
• outputting and/or storing the fourth representation and/or transmitting the fourth representation to a separate computer system.

A contrast agent for use in a radiological examination method comprising:

• receiving or generating a first representation, the first representation representing an examination region of an examination object without the contrast agent or after administration of a first amount of the contrast agent,
• receiving or generating a second representation, the second representation representing the examination region of the examination object after administration of a second amount of the contrast agent, the second amount being larger than the first amount,
• generating a third representation on the basis of the first representation and the second representation, the generating the third representation comprising subtracting the first representation from the second representation,
• generating a fourth representation, the generating the fourth representation comprising adding the third representation to the first representation α times, α being a positive or negative real number,
• outputting and/or storing the fourth representation and/or transmitting the fourth representation to a separate computer system.
