Curvilinear reconstruction is a section of tissues by a curvilinear surface whose configuration is set by the trajectory passing through the middle of this surface. This trajectory is called a curve.
To activate the Curvilinear reconstruction mode, click the Curve mode .

To adjust the curve, move the cursor to the curve, right-click the mouse and select the Set curve properties... item. You can set up the following parameters:
If you check the Set as default box, then the current settings will be used by default.

Actions with a curve can be performed only if the curvilinear reconstruction mode is active.
The following actions are available:

By the color of the curve, you can determine which part of the curve is located in front of the current image in space. This part of the curve is brighter than the part behind the image.
In Fig. 5.6, the central part and the third point are a brighter color. This means they are located in front of the current section.
To make it easier to find a node on the curve on all the projections, locate the cursor on this node. The node will be magnified on all the projections.
To rotate the surface relative to the curve, move the cursor to the bottom right-hand window (Surface by curve) and roll the mouse wheel.
To move the cutting planes to the selected point of the curve, move the mouse cursor to the selected point on the curve in the selected window. Left-click while holding down the Ctrl key on the keyboard. The point of intersection of the cutting planes is moved to the specified point on the curve in all the windows.

The curved reconstruction cross section mode is aimed for viewing the planes that are perpendicular to the curve and evenly spaced.
You can switch to this mode if a curve has been built. To switch, press the arrow on
the right-hand side of the Curve mode button and choose Curve slices mode
(Fig. 5.7).
The MPR reconstruction tab has two windows: a curved surface window and a slices window. The curved surface window is at the top of the tab, and the slices window is at the bottom (Fig. 5.8).
In the curved surface window, a straightened curve and perpendicular cutting planes projections are shown. When you mouse over a cutting plane in the curved surface window, the respective plane and projection will be highlighted. The point in which the cutting plane crosses the curve will be marked with a crosshair in the slices window.
To rotate the surface round the curve, mouse over the curved surface window and scroll the mouse wheel or move the slider in the slices window.
To move the cutting planes along the curve, mouse over the slices window window and scroll the mouse wheel or move the slider in the slices window.
To move the cutting planes automatically, activate the Play tool (see Section 5.5).
To set the curve slices parameters, press the arrow on the right-hand side of the Curve mode
button and choose Set curve slices properties... (Fig. 5.9).
A dialog box will pop up (Fig. 5.10), in which you can set the following parameters:
If you have checked the Set as default box, these settings will be used by default when you switch to the Curve slices mode.
There are two ways to activate the Curve slices properties dialog box from the right-click menu:
Rotate, Zoom, Pan and Adjust W/L tools are simultaneously activated for all the slices.
DICOM Viewer records videos, exports and prints images from the curved surface window or the slices window, whichever is active.
In the slices window, only the image from the top left-hand cell will be printed. To print or export the slice you need, move the cutting planes along the curve, so that the slice you need appears in the top left-hand cell. You can move the cutting planes by scrolling your wheel or moving the slider in the slices window.
In the slices window, video is recorded for the top left-hand cell. To record a video for the slice you need, move the cutting planes along the curve, so that the slice you need appears in the top left-hand cell.
To record a video, activate the Start video record tool (see Section 5.6).
To escape from the curve slices mode, press the arrow on the right-hand side of the Curve mode
button and uncheck the Curve slices mode box.
