Accessing DICOM MP4 Videos

Import videos associated to a study as media images (DICOM objects) using the Import Image File tool on the Image Viewer toolbar.

When importing a video, PowerReader converts the video into a DICOM MP4 video. The following video formats are supported by PowerReader: MOV, MPEG, MPG, AVI and WMV.

Importing a video into a study​

To import a video into a study, perform the following steps:

  1. Select and open the study in PowerReader.

  2. On the study desktop, click the Import Image File icon on the Image Viewer toolbar.

  3. Select the video to be imported and click Open. The Import Image Files dialog is displayed.

  4. Click Start Import.

  5. Once the video is successfully imported, the message "Media File was Successfully Imported" is displayed in the Import Activity Log section.

  6. Click Close. The video should start playing automatically.

Viewing Videos​

The following player controls are available when playing a DICOM MP4 video:

If a study has a video, the thumbnail image corresponding to the video has play icon overlay indicating that the thumbnail is a ready-to-play video.

Scrolling Behaviour​

Scrolling the mouse wheel can be used to scroll between frames on the video. If the video clip is not playing, and the last frame of the video frameset is displayed, the mouse wheel scrolls into the next frameset. Similarly, scrolling past the first frame of the video will scroll to the previous frameset. Note: it is not possible to scroll to the last few frames of a video in Windows 7.

Scrolling between video framesets:​

  1. Keyboard Pg Up / Pg Dn: the keyboard Page Up and Page Down keys can be used to scroll through framesets.

  2. Mouse default setting: the mouse can be configured to have a default Next Frameset function, i.e. Middle Click (clicking the Scroll Wheel). The default functions of the mouse is customizable and specified in Mouse Presets. Perform the scrolling operation by activating the mouse default setting for Next Frameset, if set.

Linked Videos​

When the "Link" option is turned on (via the dropdown menu on the image toolbar), all opened DICOM videos can be played simultaneously. The current frame position is preserved such that users can manually sync frameset and then press Play.

The number of simultaneous videos that can be played is configured with the System Configuration keyword "Number of Simultaneous Videos that can be played", which has a default value of 4.
