Eye Physics 3rd Generation (3D printed) Plaques: click on a model for more information

The physical dimensions of a plaque are only a rough estimator of the dosimetric coverage a plaque delivers to the base of a tumor. Dosimetric coverage is significantly influenced by the Rx altitude, seed angular orientation and optional intensity modulation of the radionuclide seed strengths in the plaque. Coverage can be several mm smaller or larger than the physical dimensions of the plaque itself.

PS6 includes .iplq6 files with embedded pictures of the face of all Eye Physics 3rd generation (prototyped using 3D printing) plaques.


Seed coordinates and other information

When seed coordinates are displayed, the origin of the plaque coordinate system is shifted to the center of the concave surface of the plaque. The X axis of this coordinate system is the Central AXis (CAX) of the plaque. In the Plaque window you are looking at a 2D projection of the plaque onto the YZ plane.

You can often click pictures with coordinates to see an enlarged view with easier to read text.

If you need seed coordinates for a spreadsheet or some other application they can also be found in the .iqa6 (xml) files that are created for the PSQACheck application.

The physical dimensions of a plaque are only a rough estimator of the dosimetric coverage a plaque delivers to the base of a tumor. Dosimetric coverage is significantly influenced by the Rx altitude and optional intensity modulation of the radionuclide seed strengths in the plaque. Coverage can be several mm smaller or larger than the physical dimaensions of the plaque itself.
