Abstract
A method of constructing a navigation table relating a set of images representative of a region of interest in a subject to a reference system with reference positions indicating known anatomic landmarks of a reference subject comprising providing reference positions for two or more images identified with two or more anatomic landmarks indicative of the region of interest with reference positions of known anatomic landmarks corresponding to the identified anatomic landmarks, and determining reference positions for the remaining images by interpolation.
Claims27
A method of constructing a navigation table relating a set of images representative of a region of interest in a subject to a reference system with reference positions indicating known anatomic landmarks of a reference subject, comprising the steps of:
- receiving a set of images representative of a region of interest in a subject;
- providing reference positions for two or more images identified with two or more anatomic landmarks indicative of the region of interest with reference positions of known anatomic landmarks in a reference system corresponding to the identified anatomic landmarks;
- determining reference positions for the remaining images by interpolation performed by a processor;
- constructing a navigation table using the processor to relate the set of images to the reference system;
- and
- storing the navigation table.
A computer program product embodied in a computer readable medium for constructing a navigation table relating a set of images to a reference system with reference positions indicating known anatomic landmarks of a reference subject, comprising:
- code for providing a reference position for an image identified with an anatomic landmark indicative of a region of interest in a subject by finding a reference position of a known anatomic landmark corresponding to the identified anatomic landmark;
- and
- code for determining reference positions for the remaining images by interpolation.
A method of processing medical images, comprising the steps of:
- receiving a set of images representative of a region of interest in a subject;
- determining the region of interest by identifying one or more first landmarks indicative of the region of interest;
- detecting one or more second landmarks in the determined region of interest;
- constructing a navigation table using a processor relating the set of images to a reference system with reference positions indicating known anatomic landmarks of a reference subject, the constructing step comprising:
- providing reference positions for images containing identified first and/or second landmarks with positions of known anatomic landmarks in the reference system;
- and
- determining reference positions for the remaining images by interpolation performed by the processor;
- and
- storing the navigation table.
