The Patient Setup Window

The Setup window provides a 3D view of the plaque, anatomy, tumor, the suture eyelets and their scleral coordinates. The 3D model behaves like a virtual trackball. For instance, to rotate the 3D model of the eye, set the cursor mode to drag eye and click anywhere on the eye and drag. To drag the plaque on the eye, set the cursor mode to drag plaque and then click on a plaque and drag it.

The status line just below the titlebar indicates which eye is being modeled and the current coordinates of the plaque center.

In addition to the buttons in this window, other setup parameters are adjustable from the Setup menu which is added to the menu bar any time this window is frontmost.

Setup window

Toolbar controls

The toolbar buttons near the top of the window select which eye is being modeled, cursor function, and the point in eye modeling space at which the OpenGL 3D rendering camera is looking at and/or orbiting.


Drag eye
Sets the cursor mode to drag eye.
Drag plaque
Sets the cursor mode to drag the plaque on the eye.

Point on eye
The next cursor click on the eye sets the rotational origin to that point.
Point on plaque
The next cursor click on a plaque sets the rotational origin to that point.

Home View
Sets the origin of rotation to the center of the eye.
Plaque center
Sets the origin of rotation to the center of the active plaque.
Eyelet center
Sets the origin of rotation to the next eyelet of the active plaque. Click again to advance from eyelet to eyelet.
Slot center
Sets the origin of rotation to the center of the currently selected slot of the active plaque.
Point of interest
Sets the origin of rotation to the currently selected point of interest. Click again to advance from POI to POI.
Sets the origin of rotation to the center of the base of the currently selected tumor.

Left Eye
Selects left eye.
Right Eye
Selects the right eye.

Status line controls
Plaque design
Optimizes the 3D appearance settings for designing new plaques.

Left side controls

The buttons on the left of the Setup window (from top to bottom) control various setup parameters:

  • Size - opens the eye size dialog.
  • Offset - opens the plaque offset dialog.
  • Lock - prevents the plaque from being moved when rotating the eye in "trackball" mode.
  • Track - forces the 2D planar dosimetry surface (e.g. meridian or equatorial) to move with the plaque.
  • Plaque rotation - rotates the plaque around its central axis. The arrows on this control rotate the plaque clockwise or counter clockwise in 1 or 90 deg. increments. You can enter the plaque angle from the keyboard by double clicking on the text field at the center of the control. You can also drag the indicator.
  • Plane position - this pair of directional controls immediately below the plaque rotation control duplicate the functionality of the 2D planar positioning controls in the Dosimetry window. The plane affected will be either the meridian or equatorial plane depending on which plane is currently selected in the Dosimetry window. The meridian plane rotates around the Anterior-Posterior (AP) axis of the eye. The equatorial plane is perpendicular to the AP axis and can be moved between the two poles.
  • Rotate - this group of six green directional controls rotates the 3D model around the indicated coordinate axis.
  • Zoom - Enlarge or reduce the 3D image over a limited range. For a greater range use the window size dialog control found in the footer controls.

Right side controls

The buttons along the right side determine which anatomic and geometric elements are rendered in the 3D model.

  • Sclera - Renders scleral surface.
  • Retina - Renders retinal surface.
  • Ciliary - Renders ciliary region surface.
  • Iris - Renders the iris surface. Optionally textures the iris surface using a digitized iris photo.
  • Cornea - Renders corneal surface.
  • Lens - Renders the lens.
  • Muscles - Renders the approximate locations at which muscles attach to the eye.
  • Nerve - Renders the optic nerve.
  • Tumor - Renders the tumor volume.
  • LandMarks - Renders digitized landmarks such as blood vessels.
  • Fundus - Textures the retinal surface using a digitized fundus photo.
  • Plaque - Renders the plaque.
  • Seeds - Renders the radioactive sources.
  • Sutures - Renders suture points on the scleral surface.
  • Axes - Renders the x,y,z coordinate axes.
  • Plane - Renders the current 2D dosimetry surface.
  • Points - Renders all point-dose calculation positions.
  • Profiles - Renders dose profile lines.
  • Meridian dose - Renders dose to the planar meridian surface.
  • Coronal dose - Renders dose to the planar coronal surface.
  • Nerve dose - Renders dose on the nerve-coronal surface.
  • Retinal dose - Renders dose to the retinal surface.
  • 3D dose - Renders a 3D isodose surface.

Footer controls

Opens the Window Size Dialog dialog.

Zoom out
Moves the 3D camera away from the eye.
Zoom in
Moves the 3D camera towards the eye.
Centers the eye in the window and returns to the 3D camera to its standard position.
Opens the Setup Appearance window wherein you can change the appearance of rendered elements.
Enables automatic font scaling of status line text to fit the window width.
