Each window and menu in Plaque Simulator is designed to organize a set of related modeling and treatment planning functions. Some of Plaque Simulator's menus are always present on the MacOS menu bar at the top of your primary display screen. Other menus are present only when the window whose functionality they are most directly related to is the key window (ie frontmost on the screen). The links in this section provide an overview of the most important of Plaque Simulator's windows, their function and their related menus.
Universal - these menus are always on the MacOS menu bar at the top of the screen.
Window specific menus are inserted between the View and Dosimetry menus.
The Setup menu is added to the menu bar when the Setup window is the 'key', or frontmost window.
The Plaque menu is added to the menu bar when the Plaque Loading window is frontmost.
The Rx menu is added to the menu bar when the Prescription window is frontmost.
The Image menu is added to the menu bar when the Image window is frontmost.
The Diagram menu is added to the menu bar when the Retinal Diagram window is frontmost.
The Isodose menu is added to the menu bar when the Isodose window is frontmost.
The Plot menu is added to the menu bar when the Planar Dosimetry window is frontmost.
The MPR menu is added to the menu bar when the MPR window is frontmost.
Plaque Simulator builds a 3D model of each patient's eye from CT (and MR) imaging. Multiplanar reconstructions allow the dimensions and curvature of the model to be interactively adjusted to the anatomy. This type of modeling assures that the plaque will be a good fit to the curvature of the eye, will not collide with the optic nerve, and enables calulation of suture eyelet coordinates prior to surgery.
In addition to planar reconstructions, Plaque Simulator also uses reconstruction of a spheroidal surface a bit inset from the inner scleral surface to map the tumor base to an azimuthal equidistant projection (aka retinal diagram). This is very useful to map tumors that are located too anteriorly to be fully imaged using optical methods such as fundus photography.
