Patient — Browse

IN THIS ARTICLE

The patient browse tab is useful for managing the patient object hierarchy. You can perform various actions on patient objects by editing and selecting them in the Browse tab.

Accessing the Patient Browse Tab

When you access a patient, the Browse tab will be activated by default. The majority of the screen is devoted to the patient viewer, where you can examine the active image set, structure set, and dose. On the left is the browse sidebar, which contains the hierarchy of patient objects. These objects can be activated by double-clicking the object you wish to activate. This operation will also activate all of the object's ancestors in the hierarchy. Eyeball icons are aligned to the right of the sidebar and can be used to toggle the visibility of entities.

In addition to allowing you to view, activate, and manage patient objects, the Browse tab also displays useful DICOM Alerts that have been identified by ProKnow DS. These DICOM Alerts are displayed as a blue information icon or an orange warning icon to the right of a particular object, as shown in the following screenshot:

By moving your mouse over the associated DICOM Alert, you can inspect the details of the alert. 

Updating the Patient Hierarchy

CAUTION: It is important to perform appropriate validation anytime you update the patient hierarchy to ensure that the new associations are valid.

  1. With the Browse tab activated, press the Edit button at the top of the sidebar.
  2. Use the object handles on the left of each row to drag an object and its children to the desired position in the hierarchy.

  3. Drop the object(s) into place.

NOTE: ProKnow allows you to re-associate any object to any valid parent (i.e., structure set with any image set; plan with any structure set or image set; or dose with any plan, structure set, or image set). However, ProKnow will display an appropriate DICOM Alert if it detects any of the following situations: (1) if a parent and child object do not share the same DICOM Frame of Reference, (2) if a structure set is associated with a different image set than originally specified in DICOM, (3) if a plan is associated directly with an image set, (4) if a plan is associated with a different structure set than originally specified in DICOM, (5) if a dose is associated directly with an image set or structure set, or (6) if a dose entity is associated with a different plan than originally specified in DICOM.

Editing Labels

  1. With the Browse tab activated, press the Edit button at the top of the sidebar.
  2. If you wish to re-label several objects with the same name, select those objects by toggling the checkbox aligned to the right of the sidebar. Otherwise, check the object you wish to rename.
  3. In the Available Actions menu, choose the Edit Patient Object Labels... option, and enter a new label name for the selected object(s).
  4. Press the Save button to save your changes.

Creating a Structure Set

  1. With the Browse tab activated, press the Edit button at the top of the sidebar.
  2. Select a single image set on which you wish to create the structures.
  3. In the Available Actions menu, choose the Create Structure Set... option, and enter a name for the new structure set.
  4. Press the Create button to create the structure set.

Deleting Patient Objects

CAUTION: Deleting patients objects is an irreversible action, so use caution.

  1. With the Browse tab activated, press the Edit button at the top of the sidebar.
  2. Select one or more patient objects to delete.
  3. In the Available Actions menu, choose the Delete Patient Objects... option.
  4. Press the Confirm button to delete the data.

Forcing a Frame of Reference

CAUTION: The Force Frame of Reference tool allows you to force the currently active objects into a consistent frame of reference. Please note that the frame of reference indicates the unique coordinate system of each patient object. By forcing consistency (i.e., overriding the default values) you take full responsibility for ensuring that the objects are in the same coordinate system. In addition, this operation will permanently override the frames of reference for the selected patient objects and is an irreversible action, so use extreme caution.

  1. With the Browse tab activated, press the Edit button at the top of the sidebar.
  2. The Force Frame of Reference... option will be available if there is one or more active patient objects with a different frame of reference than the primary image set.
  3. In the Available Actions menu, choose the Force Frame of Reference... option, which will open the Force Frame of Reference dialog.
  4. The Force Frame of Reference dialog lists the active patient objects and indicates which items have a different frame of reference from the primary image set (indicated by a warning triangle). By default, all active patient objects that have a different frame of reference will be selected, however, you may deselect specific items if desired.
  5. Once you have selected the active objects that you wish to force into the consistent frame of reference, click the confirmation checkbox and press the Apply button to apply the changes.
