3.2 Editing a segmentation

3.2.V1.9-01

After segmenting a DICOM model, access segmentation controls in the AI tab to adjust visibility and appearance of anatomical structures.

3.2.1

Structure

3.2.1.V1.9-01

Adjust visibility and transfer functions for specific parts, groups, or the background DICOM data. Group settings override those of individual parts.

Structure options

3.2.2

Options

3.2.2.V1.9-01

3.2.2.1

Smoothed segmentation

Smooths the edges of segmented structures.

3.2.2.2

Visibility controls

Controls how the structure or group is displayed. It can be hidden (HIDE), shown using the main transfer function from the colors tab (VOL), or displayed with its own segmentation transfer function (SEG).

3.2.2.3

Opacity slider

Adjusts opacity of the selected structure from 0% to 100%.

3.2.2.4

Segmentation transfer function

Enables setting transparency and colors to specific Hounsfield Units (HU) values using color pins in the segmentation.

Segmentation transfer function

3.2.2.4.1

Color picker

Changes the color of a pin.

3.2.2.4.2

Delete

Removes the selected pin from the graph.

3.2.2.4.3

Add

Creates a new pin at the midpoint of the selected color range. You can also select an empty area of the graph to add a pin at that location.

3.2.2.4.4

Color pins

Adjusts transparency and assigns colors to specific Hounsfield Units (HU) values.

Drag a selected pin vertically to change transparency (0–100%, logarithmic scale).

Drag a selected pin horizontally to assign a color to an HU value.

3.2.2.4.5

Tissue filter

Adjusts the visible range of the DICOM data using Hounsfield unit (HU) values. Move the minimum and maximum handles individually, or drag the entire range along the axis.

3.2.2.4.6

Save

Saves the current transfer function as a new preset.

3.2.2.4.7

Transfer function presets

Browse the saved transfer function presets and select one to apply it.

3.2.2.4.8

Zoom out

Restores the HU axis to the default range.

3.2.2.4.9

Zoom in

Scales the HU axis to display only the selected range.

3.2.2.4.10

Map colors to range

Switches between fixed and automatically adjusted color modes. When Map colors to range is disabled, colors remain assigned to specific HU values. As a result, narrowing the HU range may hide some colors. When Map colors to range is disabled, colors remain assigned to specific HU values. As a result, narrowing the HU range may hide some colors.

3.2.2.4.11

Close

Closes the segmentation transfer function panel.
