Tool: 2Dl Label

This tool enable you to assign "labels" to axial frames.

This tool help you label the frames. These labels can be exported as port of the slice information in the "Result (2D)" tool.

At first, all the frames labels are "Undefined". You can use the "Side View" tool to help in the labelling process.

The program differentiate between frames that have been manually labelled and the others. It will attempt to interpolate labels to all the frames that have not been manually labelled. If you only manually label 1 frame in a vertebra, the program will assume that the frame is in the center of the vertebra. If you manually label more than 1 frame with the same label, then it will assume that you have defined the 2 extremities of that vertebra and will interpolate missing labels accordingly. The same way, if you define 1 frame higher than a labelled frame as "Outside Range", then all the frames higher than that one will be "outside", the same apply for all frames lower than a labelled frame.

The labels are displayed as a text inside a round circle in the upper right corner of the frames. The color inside the circle represent the vertebral label. The color of the circle's border can be either white for frames that have been manually labelled or yellow for frames that have been interpolated by the program. A "?" is used for "Undefined" frames and a "X" for frames outside the labelled range.

From the Graphic Interface


Label Selection	Clicking on one of these will label the current frame accordingly. If the "Side View" tool is active and a selection box has been defined in that tool, all the frames inside the box will have the selected label.
Outside Range	Use this button for frames outside the labelled range
Undefined	Use this button to mark frames as "Undefined". All undefined frames between 2 defined frames will be assigned a label automatically. For example, this label can be used for a "L6" vertebra if one is present.

From the Display Area

There is no Display Area interaction specific to this tool. However, when this tool is active, a round "label" indicator will be visible in the upper right corner of the axial frames.


Undefined label	Automatically assign "L4" label	Manually assigned "Scrum" label	Manually assigned "Outside range" label

Use this button to mark frames as "Undefined". All undefined frames between 2 defined frames will be assigned a label automatically. For example, this label can be used for a "L6" vertebra if one is present.
