Collection — Structures

Accessing the Collection Structures Tab

When you access a collection, click on the Structures tab to view a list of structures that are observed across all patients that belong to the collection. The majority of the screen is devoted to a filterable list of structures. Use the filter located in the small toolbar above the table to filter the list of structures. Each row specifies the structure name, the structure count (a count of the number of occurrences of the structure across the collection), and a status bar that reflects the proportion of patients in which the structure is defined and in which it is missing.

Selecting Structures

Structures may be selected in several ways:

Click on the row to select only that row.
Click on the checkbox in the first column to add the patient to the selection.
Ctrl + Click on the row to add the structure to the selection.
Shift + Click to add a range of structures to a selection.

Restrictions for Renaming and Merging Structures

A name conflict can occur if you try to rename a patient structure with a name that matches another structure in the same patient structure set. When ProKnow detects these errors, it will skip the renaming operation for the patient and report the error at the end.
Structure rename and merge operations will also be skipped if there is already a draft of the structure set in progress. When ProKnow detects these errors, it will skip the renaming operation for the patient and report the error at the end.

Note: You must have Contour Patients permission on a patient to rename or merge structures for that patient.
