The fastest and most accurate 3D verification system

The Delta4 Phantom+ system offers the most accurate and efficient verification of your IMRT, VMAT, Halcyon, Radixact, and TomoTherapy plans.

It is the ONLY system that measures the dose distribution in the isocentric region and not simply in one single flat or wrapped plane.

The patented geometric, dual orthogonal detector planes and the nature of the detectors make the Delta4 Phantom+ a unique quality assurance system.

Fulfills the requirements in TG-218

Verifies IMRT, VMAT, Halcyon, SRS, SRBT, RadixAct and TomoTherapy plans

One system for patient and machine QA

Delta4 Software

Streamline your workflow

Integrated in the workflow

Keep up an efficient clinical workflow, thanks to well-integrated software. TPS plans can be easily imported together with TPS dose and structures.

Intuitive interface

Easily navigate between patients, measurements, and analysis. All the information you need is just a click away. The QA analysis is performed automatically as soon as the dose has been delivered, instantly indicating pass or fail.

Delta4 Software

Instant and accurate analysis

Instant results

Your QA results, including dose deviation, distance to agreement (DTA), and gamma index, become available instantly—no further processing required. Easily customize QA reports to meet your specific needs.

Powerful analysis

The unique 4D measurements yield the data needed to analyze the delivered dose for fraction, beam arc, or control point. The delivered 4D dose can also be analyzed in the patient’s anatomy. The Delta4DVH suite of software modules provide unique analysis tools for finding the clinical significance of a deviation.

Testimonials

What our customers say

We chose to work with ScandiDos for our internal testing of the Synchrony® feature for the Radixact® System, because they had a robust solution for comprehensive quality assurance of moving targets. We have found the Delta4 Phantom+ and the Delta4 HexaMotion to be convenient, accurate, and easy to use.

Dylan Casey, PHD Director of Medical Physics & Systems Analysis at Accuray Incorporated

The Delta4 Phantom+ is a valuable tool for us at Herlev Hospital. We find great value in having an independent measurement of treatment plans. At Herlev Hospital we now have a complete range of Scandidos' Delta4 products covering TrueBeams, Halcyons and MRIdian.

Ulf Bjelkengren Technical Manager, M.Sc., Medical Physics, Herlev and Gentofte Hospital

The Hexamotion platform allowed for accurate phantom positioning and motion for a wide range of simple and realistic patient motions and The Delta4 phantom was found to be very reliable, easy to setup and allowed for easy analysis of dose delivery accuracy. The combination of the two allowed for validation of the Radixact Synchrony.

Lee Goddard Medical Physicist, DABR, Montefiore Medical Center, Bronx, NY

The design of the device is very clever and a great deal of dosimetric information is available virtually instantaneously after the plan is delivered. The major advantage is the ability to compare the dose at the fraction, beam or even individual segment levels, which allows to quickly evaluate and explain any disagreements.

Vladimir Feygelman, PHD ASSISTANT PROFESSOR, DIVISION OF RADIATION ONCOLOGY, MOFFITT CANCER CENTER, TAMPA, FL, USA
