LUCY® 3D QA Phantom End-To-End Stereotactic QA

Unrivaled 0.1 mm accuracy minimizes errors at each link in the stereotactic QA chain.

Lucy feature scan 1400


A variety of targeting inserts are available for testing accuracy.

Lucy feature plan 1400


Create and deliver a plan based on known geometry. Measure cumulative errors and systemic uncertainties from end-to-end in the stereotactic QA chain.

Ion chambers or film can confirm prescribed dose and software can help with automatic analysis of TG-142 recommended tests.

Be Precise

Validate the Complete Stereotactic QA Chain

The Lucy 3D QA Phantom exceeds strict demands set by physicists performing SRS/SRT QA. Each component of the Lucy phantom 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.

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.

Lucy® 3D QA Phantom Introduction

A quick introduction to the Lucy 3D QA Phantom for end-to-end stereotactic QA.

The Lucy Phantom is a multipurpose phantom for clinical medical physicists. Not only is Lucy a very important tool for Stereotactic Radiosurgery but it is also ideal for CT and MRI QA work.

Chief Medical Physicist

Combined with the A16 chamber, the LUCY Phantom is an exceptional QA device. It is so easy to use with ExacTrac that we use it to perform patient specific QA for every SRS patient treated on our Novalis TX.
