With the most clinical users worldwide, the Lucy 3D QA Phantom has exceeded the strict demands set by physicists performing SRS/SRT QA. Each component is manufactured within 0.1 mm tolerances, ensuring the most precise, practical SRS tool on the market.

 

Fast, Easy and Customizable Setup

The Lucy 3D QA Phantom interfaces with most commercial SRS frames and frameless systems for fast setup and verification of placement accuracy in patient treatment conditions. The SRS frame (with Lucy) is mounted on the couch and treated within the manufacturer’s exact coordinate system.

 

Features & Benefits Confident Image Fusion

Use Lucy to verify the accuracy of image fusion with a single phantom. Fused images can be compared to measurements described in the Lucy specifications to ensure sub-millimeter precision.

 

Minimize Transfer Errors

Industry-leading manufacturing tolerances provide incomparable accuracy when contrasting the Lucy volumes, geometry and distance measurements to images in treatment planning software. Since these measurements should be evaluated at each step of the imaging process, these rigid tolerances can drastically reduce cumulative uncertainty.

 

Simple Patient Dosimetry

The dosimetry inserts for the Lucy quickly obtain absolute, relative and point-dose dosimetry measurements at isocenter and at exact positions off isocenter. This allows for a seamless evaluation of dose as well as geometric accuracy, including CBCT and MV/kV alignment.

 

CT, MRI and Image Fusion

The Lucy seamlessly integrates with SRS frames and frameless systems. It can be positioned within the manufacturer’s coordinate system and rotated for operation in coronal, sagittal or transverse plane. CT/MRI marker cylinders and volume inserts provide known volumes, densities and distances to produce unparalleled 0.1 mm precision when evaluating TPS fusion.
