Isocenter Optimization

3D Winston-Lutz (Isocenter Optimization)

Now with accuracy surpassing sub-pixel resolution!

The RIT Family of Products come equipped with an automated 3D Stereotactic Alignment routine to give you a fast and accurate measurement of isocenter accuracy, allowing you to optimize your SRS/SBRT delivery. Using only a set of EPID Winston-Lutz images, the RIT system will calculate deviations between radiation and mechanical isocenter, determine ball/BB setup error, and suggest couch alignment adjustments to optimize your system’s accuracy. Additionally, this routine enables individual component (gantry, collimator, couch) characterization to better understand distinct contributions to isocenter deviation, giving insight into adjustments that can be made to improve delivery performance, if needed.

RIT's Isocenter Optimization routine allows for optimal cone detection, resulting in the utmost precision.

Eliminate your need for films and increase your accuracy using Virtual Star Shot* with ANY combination of angles, reconstructed using a set of Winston-Lutz images in it’s dedicated window!

Radiation vs. Light Field (Regular and Asymmetrical)
This Radiation vs. Light Field routine measures how well radiation and light field positions coincide for conformance with TG-142 recommendations. The routine can be used with a variety of phantoms, including the RIT L-Rad phantom. The routine can make use of EPID images of the radiation field and can adapt to a variety of SIDs, asymmetric, and custom field sizes. Besides radiation-light field coincidence, the routine measures field symmetry and flatness, penumbra width, and field edge orthogonality in vertical and horizontal directions.
Star Shot Analysis
The classic Star Shot routine measures the mechanical alignment of the gantry, the collimators, and the table. It automatically finds the star shot beam centers and edges to calculate misalignment using a variety of measures. EPID images of several spokes can be easily combined to analyze star patterns with the built-in Image Compositor tool.

Gibbs Cone Analysis (Pictured)
This routine measures the cone wobble when using a single cone (repeated), or cone center shift when using multiple cones. This provides an accurate test of either the cone wobble, collimator walkout (if the collimator is rotated during the test), or both.
