|
This routine measures the mechanical alignment of the gantry, the collimators, and the table. It automatically finds starshot beam centers and edges to calculate misalignment using a variety of measures. This improved routine allows the user to find:
 |
The smallest tangential circle that will touch or cross all beam centers |
|
The largest perpendicular distance from the beam center intersection centroid to any beam center |
|
ANSI Standard N449.1 Gantry misalignment statistics |
|
Maximum distance between beam intersections |
| The beam geometry data can be exported for further calculations. |
