Description

Register Studies

Use for general or global registration.

Allows you to click on two or more studies. After you click the specific dataset, group, or series in each study, Register Studies automatically applies an algorithm to the datasets. The algorithm matches any two volumes from two studies, and automatically maps each pixel in one study to the relevant pixel in the other study.

Refine Registration

Use for focusing on local regions and comparing the regions.

Allows you to focus on a certain region, and then compare the specific region in the two studies. Adjusts the registration algorithm result.

Guided Registration

Provides global registration that is assisted, precise, and based on manual local matching. Useful to apply when two scans cover a small region of common volume with a small area of overlap.

Applies the registration algorithm based on registration points. To create a registration point, you must click the same anatomical region in each study. The points are factored into the registration algorithm to represent similar anatomical locations. The registration points allow Guided Registration to more quickly and more accurately match the volumes and map the relevant pixels in each study.

Manual Register Studies

Use when the registration results from Register Studies or Guided Registration are unsatisfactory.

Matches the two volumes based on the planes of the two studies and on the position of the two points that you create by clicking on each study. You must manually match the orientation and the register points between the groups. Manual Register Studies applies an algorithm based on the input you supply. The results for Manual Register Studies can vary according to the accuracy of the input you supply.

Treat as Registered

Use for situations where the series are registered in the modality, but the DICOM data does not reflect the registration.

For example, you might have a PET series which does not have the same frame of reference but was registered in the modality before the study was copied into the PACS. After you click on the dataset, group, or series in each study, the studies are considered registered.

Break Registration

Use to remove the registration points, algorithm calculations, and volume matches from the study.

 Removes any type of registration for any active datasets, groups, or series in a study.
