The Plaque Loading Window

The Plaque window is used to select a plaque, load sources into a plaque, and design new plaques. In this example the plaque file COMS14P.iplq6 has been loaded. The "P" in the file name "COMS14P.iplq6" indicates that this plaque model includes an embedded scanned photo of the plaque. The extension ".iplq6" indicates that this is a PS version 6 plaque file. PS version 6 plaques are packages (a package is a folder masquerading as a file) which contains an xml file describing the plaque and .png files with pictures of the shell and carrier. PS version 5 files were binary files. PS version 6 can import most version 5 binary files.

The status line just below the title bar indicates the active plaque index (P1..P4) and information concerning the current radionuclide inventory selection.

To load sources into a plaque, select a batch of sources from the radionuclide inventory database by clicking on the Source button. The status line will change to reflect the active inventory selection. Set the cursor mode to Load slot, and then click on a slot position placeholder. Slot placeholders typically appear as thin brown lines. Filled positions are drawn with a 3D rendering of the source. To return a source to the inventory, simply click on it. As you add sources to the plaque they will also appear in any other windows which display sources.

In addition to the buttons in this window, many other plaque related parameters and functions are accessible from the Plaque menu which appears on the menu bar any time this window is frontmost.

Plaque window

Toolbar controls

The toolbar buttons near the top of the window select which plaque is currently being edited, cursor function, and window layout. Plaque simulator supports up to 4 plaques per plan. The default condition is to allow only one of these plaques to be "active", or "editable", for dosimetry purposes. In most instances you will simply use plaque #1 for planning, with plaques 2..4 reserved to optionally compare alternate plaque designs and loading patterns.

Left side controls

The buttons on the left of the Plaque window (from top to bottom) control various aspects of the plaque and its display in this window:


PlaqueControlsLeft
  • Rulers - Superimposes a ruled grid on the plaque to assist with plaque design. The rulers can be dragged by clicking on them.
  • Labels - Labels each source with its strength at time of implant and other optional information.
  • RotationMenuCarrier rotation - if a plaque has a carrier (such as the COMS and ROPES plaques) this control rotates the carrier around the central axis of the plaque. The corner arrows within this control rotate the carrier clockwise or counter clockwise in 1 or 90 deg. increments. You can also drag the indicator. This control also offers options to rotate the entire plaque and embedded pictures of the face or carrier. To access these contextual options control-click (or right mouse button) the control and select the desired control context.
  • Source - Opens the radionuclide inventory window.
  • Picture - enables display of a scanned picture of the plaque if one is available.
  • Load - Loads all source positions in the active plaque with the current inventory selection.
  • Unload - Returns all sources in the active plaque to the inventory.
  • Face (view) - Switches between face (concave) and back (convex) views of the plaque.
  • Lock - Locks the radionuclide in a plaque. A password is required to unlock and edit the radionuclide of a locked plaque. Locking the plaque loading is primarily used to protect permanently loaded plaques files such as the BEBIG Ru-106 plaques.
  • Auto Dose - When enabled, planar and retinal dose matrices are automatically recalculated after any change to the plaque loading or location or the dosimetry surface. Enabling auto dose is not recommended for Ru plaques due to the much longer calculation time required.
