MEDICAL IMAGE REGISTRATION

Reliable and performant compensation of patient movements between different image acquisitions and modalities.


Our Medical Image Registration Features

With Chimaera's Medical Image Registration, it becomes possible to compensate for misalignment up to and including complex patient movements between different image acquisitions, whether for follow-up images, stitching of images, or acquisitions with different imaging modalities such as CT, MR or PET/SPECT.

Provided as an OEM component with C-API, our Image Registration is perfect for extending existing customer applications with additional features that require accurate spatial mapping.


Rigid Registration

Rotation and translation only

Image content is not modified

No manual parameterization needed

2D, 3D, and time series

Supports multi-modal data (e.g. CT, MR, PET, SPECT, etc)


Nonrigid Registration

Computes complex deformations between images

Deformation field can compensate for respiratory motion, cardiac motion, patient positioning, etc

Easy and flexible parameterization for different use cases

2D, 3D, and time series

Supports multi-modal data (CT, MR, PET, SPECT, etc)

Applications for Medical Image Registration

Rigid Registration

The transformation between the images is limited to only rotations and translations. This method is often used to establish a link between different scanner coordinate systems or to account for rigid body movements while the image content does not change:

Retrospective image fusion (e.g. for PET/CT, PET/MR, etc)

Side-by-side viewing of follow-up studies

Image stitching

Nonrigid Registration

Nonrigid (also sometimes denoted as deformable or elastic) image registration techniques allow far more degrees of freedom in terms of deformation compared to rigid registration. Complex deformations between images often need to be calculated to compensate for respiratory motion, cardiac motion, slight differences in patient positioning, or other types of soft tissue misalignments. Cross-patient registration is also possible to create atlases on different subjects.

Perfusion imaging

Difference imaging

Atlas registration

Transfer findings to follow-up study

In the following use case, we demonstrate how nonrigid image registration can compensate complex organ movement between a non-contrasted and an arterial phase of an MR perfusion image study.

 Can non-rigid image registration compensate for respiratory motion?

Yes, this is achieved by calculating a compensation transformation (deformation field) that corrects the deformations in the thorax area caused by breathing motion.


 Is the Image Registration suitable for atlas creation and application?

With our non-rigid image registration, images from different patients can be combined to create an atlas. In addition, new images can be registered with the atlas. One application for this is, for example, the transfer of a segmentation atlas (brain atlas).


 Can Image Registration also be used for industrial applications?

Of course, our Image Registration can be used for both 2D and 3D applications in an industrial environment, e.g. for position corrections of workpieces, for camera stitching or for calibration applications.
