## Viewports

A viewport is a panel where images in a series are displayed and manipulated.

Viewport components

The following table describes the viewport components.

Viewport component | Description
Series Selector button | Identifies the study and series displayed in the viewport. For example,
| • | A:1 denotes the anchor study, first series
| • | R1:1 denotes the first reference study of any modality, first series
| • | R1 (CT1):1 denotes the first reference study of CT modality, first series
In addition, the Series Selector buttons distinguish the open studies by having different colors and font styles.
Display Mode icon | Indicates the types of images currently displayed. In addition, you can:
| • | Select the display mode for the series. See Selecting the series display mode.
| • | Display all images, selected images, or flagged images in the series. See Specifying the series viewing scope.
| • | Create Multi-Planar Reconstruction (MPR) images. See About creating MPR images.
Viewport Layout icon | Enables you to specify how many images to display in the viewport. See Setting the viewport layout.
Link icon | Indicates whether the series is currently linked with another series. A linked series can be scrolled with other linked series. You can link or unlink the series. See Linking and unlinking series.
Chits | A chit may represent one image or a group of two or more images within a series. This depends on the following factors:
| • | Number of images contained in the series
| • | Size of the viewport
| • | Screen resolution
You can display an image by clicking the corresponding chit. If the chit represents a group of images, click the chit to display the first image within the group, and then rotate the mouse wheel backward to scroll through the rest of the images. Warning: To ensure that all images that you want to view are displayed, and that no image is unintentionally skipped, first click the image, and then rotate the mouse wheel backward or forward, depending on the direction in which you want to scroll through the series. Depending on the number of images contained in the series, different display properties are applied to the chits. See Chit display properties. Chits can appear in different colors. See Chit colors.
Pin icon | Indicates whether a viewport is pinned or not. A pinned viewport is not used in cycling series. See Cycling series. You can pin or unpin a viewport. See Pinning and unpinning a viewport.
Image viewing area | Holds images in the series. You can manipulate displayed images. See Working with images.
Patient orientation markers | Patient orientation markers are located on all four sides of the viewport. These markers indicate the orientation of the patient anatomy in the viewport. Warning: When you reorient the image, note the patient orientation markers to confirm the actual orientation of the patient when the study was performed. You cannot hide patient orientation markers. They are always displayed on each image provided that valid orientation information is available in the image DICOM header. When no information is available in the DICOM header, patient orientation markers will show as blank in Change Healthcare Radiology Solutions. Warning: Change Healthcare Radiology Solutions relies on the accuracy of the DICOM header information in the image. If you suspect there may be a mismatch between the image and patient laterality/orientation, work with the technologist and other physicians at your facility to obtain accurate patient orientation information. For details on the meaning of each marker, see Patient orientation markers.

Patient orientation markers

The following table lists the patient orientation markers:

Marker | Meaning
A | Anterior
P | Posterior
R | Right
L | Left
I | Inferior
S | Superior

Chit colors

Chits can appear in different colors. Different chit colors help you to identify the following items:

| • | Active images

| • | Visible images

| • | Selected images

| • | Viewed images

| • | Loaded images

| • | Partially loaded images

| • | Not loaded images

| • | Images marked for deletion

The chit colors are assigned at installation. For details, contact Change Healthcare Support.

Chit display properties

Depending on the number of images contained in the series, chits can have different display properties. The following table describes the chit display properties.

Chit display property | Description
Fully expanded | Image numbers are displayed on the chits.
Partially compressed | The series contains a higher number of images. Image numbers are not displayed, and the chit width is reduced.
Fully compressed | The series contains an even higher number of images, and the chits are shown as a continuous band.
