Figure 1-1: Add/Subtract screen

Select Set 1

Defines the first image set.

Select Set 2

Defines the second image set.

Equal (=)

Performs the selected operation and generate the new images.

Ratio slider

Increases pixel weighting of the left (first) image when moved to the left and increases pixel weighting of theright (second) image when moved to the right. The slider is only available during addition and subtractionwhen both Select Set buttons are selected.

Save Series

Displays the current series and starting image number of the saved series. By default, images resultingfrom subsequent operations are added onto the end of the same series unless you click New Save Series.

New Save Series

Places images resulting from subsequent operations into a new series in the Patient List. If you do not selectthis option, the images are saved in the current saved series.

Mode

Max creates a new series that finds the highest corresponding signal intensity values in the selected set orsets of images.

Plus (+) creates a new series that adds the image intensity values of the selected image sets.

5561231-1EN Rev 1 (Aug. 2014) 4© 2014 General Electric Company

Minus (-) creates a new series that subtracts the image intensity values of the selected image sets.

Min creates a new series that finds the lowest corresponding signal intensity values in the selected set orsets of images.

Bind creates a new series that consists of copies of the selected images from one or more existing series.

Accept Negative Pixels

Allows negative pixel values in the resulting images. If this function is not enabled, all negative pixel valuesare set to zero. This operation is useful on pre- and post-contrast studies of the same slice location.

Disable Normalization

Performs a pixel by pixel addition or subtraction. The images are not normalized.

Disable Normalization is available for both addition and subtraction.

If Accept Negative Pixels is not selected the negative pixels are scaled to zero and the resultantimages are clipped to 16 bit if they go beyond the bounds of 16 bit images.

If both Accept Negative Pixels and Disable Normalization are selected, then Add/Subtract acceptsinput of negative pixels and performs a true pixel-by-pixel subtraction. A message is displayed if anyoverflow beyond the 16 bit image size occurs.

Clear Selection

Erases the selections so that both Select Set buttons have no prior values associated with them.

Chapter 18 : Image Management

Archive/Network

ArchiveAn archive device is a network device set up as an archive destination by your service personnel. When animage is archived, an archive flag displays in the Patient List. The archive flag does not display when animage is saved to a CD1/DVD2.

There are two methods of archiving. You can manually archive images, which allows you to save only thosespecified by you. You can also automatically archive images. In this case, all exams are auto archived uponscan completion.

The archive status on the Patient List contains the following information regarding the archive status:

The icon( ) indicates the images have been archived to the default archive device.The blank indicates the images have not been archived.

When saving images to a remote archive device such as a PACS, items queued to be saved to the devicewill be listed on the JobManagement screen.

The archive status is displayed in the Job Management screen and the Feature Status area of the screen.

NetworkA networks link image acquisition systems and workstations together, providing a way to quickly and easilytransfer images between your scanner, remote workstations, and other image acquisition systems. Youmay view images that are supported by your scanner from any station, or view images from other stationsnetworked to your scanner.

You can network images between your system and any DICOM compatible device. Images transferred fromyour system can be automatically networked upon reconstruction or manually networked upon yourinitiation. You may also get images from another networked device. Before networking images, check tosee that there is enough room on the receiving system's disk to accommodate the images beingtransferred.

The network status on the Patient List contains the following information regarding the network status:

The icon ( ) indicates the images have been transferred to the network device.The blank indicates the images have not been transferred.

The network status is displayed in the Job Management screen and the Feature Status area of the screen.

Images cannot be sent to a IRIX based CT systems.

Archive/Network queues: Job ManagementThe archive and network queues are viewed from the Job Management screen. When you choose to viewan archive or network job, the queues provide a snapshot of the status of the archive or network tasksoccurring on the system. You are able to pause, resume, and delete the archive and network tasks.

The Job Management feature also provides a history of archive and network events. The list allows you tocheck and verify that an exam/series/image has been sent to an archive or network node. If an entire examor series has been selected, only one transfer is executed and one entry is displayed in the queue. If specificseries or images have been selected, a separate transfer is executed and a separate entry is displayed foreach selection. When saving images to a remote archive device such as a PACS, items queued to be savedremotely will be listed in the Archive Queue under the Remote archive list.

After a system crash or reboot, check the queue status and restart if necessary. The restore and savequeues are maintained even after a shutdown has been performed.
