Markers Menu

Markers/Create Marker

If the mouse is in the slice window over a volume pixel, a marker is created at that location. Otherwise, it is created at the current cursor position.

Markers/Create Marker

If the current object is a marker, then changes the marker's position in a manner similar to Markers/Create Marker.

Markers/Default Size

Prompts the user to type in the default marker size in millimeters.

Markers/Default Label

Prompts the user to type in the default marker label string.

Markers/Default Colour

Prompts the user to type in the default marker colour.

Markers/Default Structure Id

Prompts the user to type in the default structure id.

Markers/Default Patient Id

Prompts the user to type in the default patient id.

Markers/Default Type

Prompts the user to type in the default marker type, of which only cube is supported.

Markers/Chg Marker Size

Prompts the user to type in the new size of the current marker, if the current object is a marker.

Markers/Chg Marker Label

Prompts the user to type in the new label of the current marker, if the current object is a marker.

Markers/Chg Marker Type

Prompts the user to type in the new type of the current marker, if the current object is a marker.

Markers/Chg Structure Id

Prompts the user to type in a structure id. If the current object is a marker, then it is assigned this structure id. If the current object is a model, then all markers underneath this object are assigned this structure id.

Markers/Chg Patient Id

Prompts the user to type in a patient id. If the current object is a marker, then it is assigned this patient id. If the current object is a model, then all markers underneath this object are assigned this patient id.

Markers/Save Mrkrs as .tag

Prompts the user to type in a filename. If the current object is a model, all markers underneath it are saved to a file in .tag format, which can be later read by display or the register program. If the current object is a marker, then the marker and all markers at this position in the object hierarchy are saved to the file.

Markers/Load Markers

Sames as the File/Load, to allow easy access to loading markers.

Markers/Move to Marker

If the current object is a marker, sets the 3D cursor and the volume position to the position of the marker.

Markers/Move Cursor Home

Markers/Delete Object/Really Delete

Deletes the current object in the object hierarchy.

Markers/Classify Markers

Attempts to group markers by relative proximity, generating a different colour and structure id for each group.

Markers/Segment Thresh

Prompts for and sets the distance threshold which determines if two markers are close enough to belong to the same group. Default is 1.5.

Markers/Pick Modify Marker

Allows the user to draw a rectangle on the 3D view of the markers and change all the markers within the rectangle to the default settings. This is done by pressing and holding the left button, sweeping out a rectangle, and when the left button is let go, the defaults are copied to the markers.

Markers/Defaults -> Current

Copies the default marker values to the current object, if it is a marker.

Markers/Defaults->Many

Copies the default marker values to all markers which have the same patient id and structure id as the current object, if it is a marker.
