Registration aid for medical images
First Claim
1. A registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, said registration aid comprising:
- a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time; and
at least one landmark provider carried by said carrier, said landmark provider providing a first landmark visible in a first of said imaging modalities and a second landmark, different from said first landmark, visible in a second of said imaging modalities, said landmark provider providing said first and second landmarks with a fixed spatial relation relative to each other to allow contents of an image obtained with said first of said imaging modalities to be brought into registration with contents of an image obtained with said second of said imaging modalities, with said carrier being applied to the examination subject while each of said images is obtained.

Abstract
A registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, has a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time, and at least one landmark provider carried by the carrier, the landmark provider providing a first landmark visible in a first of the imaging modalities and a second landmark, different from the first landmark, visible in a second of the imaging modalities. The landmark provider provides the first and second landmarks with a fixed spatial relation relative to each other to allow contents of an image obtained with the first of the imaging modalities to be brought into registration with contents of an image obtained with the second of the imaging modalities, with the carrier being applied to the examination subject while each of the images is obtained.

13. A registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, said registration aid comprising:
-
a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time; and
at least one landmark provider carried by said carrier, said landmark provider comprising a holder having an opening therein giving said holder a cross-section that is visible in a CT image, and vessel containing a PET-specific radioactive substance that emits radiation to cause said vessel to be visible in a PET image, said holder being permeable to said radiation. - View Dependent Claims (14, 15, 16, 17, 18, 19)

20. A registration aid for medical images obtained from an examination subject respectively with different imaging modalities at separated points in time, said registration aid comprising:
-
a carrier adapted to be reproducibly applied to an examination subject at separated points in time at a substantially identical position on the examination subject at each of the separated points in time; and
a landmark provider carried by said carrier, said landmark provider comprising an elongate tube attached along a substantial extent of said carrier and having a cross-section visible in a CT image, said tube being filled with a PET-specific radioactive substance that emits radiation allowing said radioactive substance to be visible in a PET image, said tube defining a non-zero angle with respect to a longitudinal axis of the examination subject when said carrier is applied to the examination subject. - View Dependent Claims (21)
