Scout Lines

 

This tool enable you to display a line representing the position of a frame in all the other frames that that frame crosses. It will also enable you to visualize in real-time the current position of the cursor in all the other frames.  And finally you can select the current frame by pointing at it in the scout image.

 

Note:

 

For a scout lines representing one frame to be visible on another frame, they need to be an intersection between the 2 frames and they need to be in the same coordinate system (same value of the tag (0020,0052) "Frame of Reference UID" in DICOM)

Scout options

The Scout Lines tool offer you 3 options:

 

Lines for visible

Display pilot lines for all frames currently visible in other window.

Lines for all

Display pilot lines for all the frames currently loaded in sliceOmatic.

 

Track cursor

A cursor will be drawn on each frames that share the pixel currently under the mouse.

 

Track frames

When moving the cursor over the selected window, the current frame in the other windows will change to track the cursor. The new current frame in these windows will be the frame, from the same "group" as the old current frame, that is closest to the cursor position. 

 

Clicking the mouse key when the cursor is over a geometry in a 3D window, will cause the current frames in all windows to track the point on the geometry that is under the mouse.

 

Note:

The "Lines for visible" and "Lines for all" options are mutually exclusive. Selecting one of these will automatically de-select the other.

 

Color Editor

You can modify the color associated with the scout lines with the slider.

 

 

From the Display Area

 

In mode "Track frame", moving the cursor over the selected 2D window will cause the current frame in all other windows to track the cursor.

 

In mode "Track frame", Clicking the mouse key when the cursor is over a geometry in a 3D window, will cause the current frames in all windows to track the point on the geometry that is under the mouse.

 

In all modes, pressing the "." key, will cause the current frame in all windows to change to the frames that contain the cursor.

Action

 

 

.

"." has been mapped to the command: "Scout: Select".

 

Pressing the "." key while over a scout will change the current frame of a group to the frame at the corresponding position on the scout.  An example of use of this option, if you have a set of axial slices and a scout, is to have 2 window open. In one window you show the scout image, the other window is in display Mode One and displaying one of the axial frames.  Pressing "." while over the scout will change the frame in the second window to the matching axial slice.

 

 

,

"," has been mapped to the command "Scout: mode 0x08".

 

Pressing the "," key will toggle the mode "Track Frames".

 

 

 

From the Command Line

 

Text commands defined in this tool:

 

Scout: Mode bit_field

Toggle the the current scout line mode:

0x01 = "Lines for visible frames"

0x02 = "Lines for all the frames"

0x04 = "Track cursor"

0x08 = "Track frames"

 

Scout: Select

Activating this command while over a scout will change the current frame of a group to the frame at the corresponding position on the scout.  If the cursor is over a geometry in a 3D window, the program compute the position on the polygons under the cursor, and change the current frames to the frames that contain that position in their image plane.

 

Note:

 

The "Scout: Select" command use the current mouse position.  So the command is only valid while the cursor is over a frame or a 3D geometry.
