Merge Frames

Merging a number of static image series into one dynamic study.

This function is explained in a separate section.

Merge Slices

Merging of a number of static image series in axial direction.

Activating Merge Slices opens a dialog window for choosing among the loaded series and changing their order. The studies selected for merging are then combined in the axial direction to form a static series with extended coverage.

There are two options available for merging: Merge one single frame study and Merge frame by frame.

This function is only reasonable for image series covering adjacent axial fields-of-view such as in whole-body scanning.

Note that at least two studies have to be selected for merging

Rearrange Z&T

The result is a one multiframe study with a new number of slices and frames.

Average studies

Calculating the average value of each pixel across the loaded image series.

Result is the average image series, while the individual image series are removed from PVIEW.

Standard Deviation

Calculating the standard deviation of  the values in each pixel across the loaded image series.

Result is the standard deviation image series, while the individual image series are removed from PVIEW.

Split Frames

Splitting a dynamic image series into a set of static series.

Activating the button causes PVIEW to split the current dynamic series into a set of static series (one per time frame) which can be separately displayed.

If the To disk box is checked, the Output Format selection becomes active. In this configuration, a saving dialog appears when the Split Volumes button is activated, and the new static series are saved to disk.

Split Slices

Splitting a 3D static image into a set of  2D static series.

If the To disk box is checked, a dialog window appears allowing to select the Output Format.

Slice corr.

Calculates a rigid 2D transformation between marker pairs defined on slices.

The first slice with valid markers serves as the reference. This function could be useful when merging slices which have been acquired separately (eg. by autoradiography of small animals) into a volume.

Note that at least three markers on two slices need to be defined.

Frame corr.

Motion correction for a dynamic series with external markers (translations only).

Calculates the transformation between frames and corrects them based on the assumption that the maximal value contained in a VOI should remain stable.

Note that at least one VOI must be defined (in case of multiple VOIs the first one on the list is going to be used during the correction). It is important that VOIs are in dynamic mode.
