Multi image fusion based positioning verification

A computer-implemented method for verifying a relative position of a plurality of anatomical structures of interest of a patient, the method comprising:

• acquiring planning data describing at least one planning-image showing the plurality of anatomical structures;
• determining first identification data based on the planning data describing a position and/or shape of at least two of the plurality of anatomical structures of interest within the at least one planning-image;
• acquiring verification data describing at least one verification-image showing the least two of the plurality of anatomical structures of interest;
• determining second identification data based on the verification data, describing a position and/or shape of the at least two of the plurality of the anatomical structures of interest within the at least one verification-image;
• determining transformation data based on the first identification data and the second identification data describing, for each one of the at least two anatomical structures, a distinct image fusion transformation;
• and
• determining evaluation data based on the transformation data, describing, for at least one first image fusion transformation, whether the at least one first image fusion transformation is within a predetermined threshold, by taking into account at least one second image fusion transformation.

A non-transitory computer-readable storage medium storing a computer program which, when executed on at least one processor of at least one computer, causes the at least one computer to perform the steps comprising:

• acquiring planning data describing at least one planning-image showing the plurality of anatomical structures;
• determining first identification data based on the planning data describing a position and/or shape of at least two of the plurality of anatomical structures of interest within the at least one planning-image;
• acquiring verification data describing at least one verification-image showing the least two of the plurality of anatomical structures of interest;
• determining second identification data based on the verification data, describing a position and/or shape of the at least two of the plurality of the anatomical structures of interest within the at least one verification-image;
• determining transformation data based on the first identification data and the second identification data, describing, for each one of the at least two anatomical structures, a distinct image fusion transformation;
• and
• determining evaluation data based on the transformation data, describing, for at least one first image fusion transformation, whether the at least one first image fusion transformation is within a predetermined threshold, by taking into account at least one second image fusion transformation.

A system for verifying a relative position of a plurality of anatomical structures of interest of a patient, comprising:

• at least one computer having at least one processor and associated memory, the memory having instructions that when executed, perform the steps of;
• acquiring planning data describing at least one planning-image showing the plurality of anatomical structures;
• determining first identification data based on the planning data describing a position and/or shape of at least two of the plurality of anatomical structures of interest within the at least one planning-image;
• acquiring verification data describing at least one verification-image showing the least two of the plurality of anatomical structures of interest;
• determining second identification data based on the verification data, describing a position and/or shape of the at least two of the plurality of the anatomical structures of interest within the at least one verification-image;
• determining transformation data based on the first identification data and the second identification data, describing, for each one of the at least two anatomical structures, a distinct image fusion transformation;
• and
• determining evaluation data based on the transformation data, describing, for at least one first image fusion transformation, whether the at least one first image fusion transformation is within a predetermined threshold, by taking into account at least one second image fusion transformation;
• the at least one computer operable to issue a control signal to a medical device on the basis of at least the evaluation data.
