Independent QA with Delta4
From prescription to final fraction
Delta4 provides independent quality assurance solutions for medical physics teams throughout the radiotherapy workflow. Our solutions support patient-specific QA, motion management, and machine QA, helping teams efficiently verify complex treatments.
Measure where it matters
Delta4 Phantom+ for patient-specific QA
Delta4 Phantom+ provides independent 4D dose verification in the isocenter region for IMRT, VMAT, SRS/SBRT, Halcyon, MR-guided radiotherapy, Radixact, and TomoTherapy.
With two orthogonal detector planes and instant analysis, Delta4 Phantom+ provides efficient verification of complex treatment plans with results available immediately after delivery.
When motion matters
Delta4 HexaMotion for motion management QA
Delta4 HexaMotion adds realistic motion to patient QA, enabling medical physics teams to simulate tumor movement and breathing patterns during treatment verification.
Combined with Delta4 Phantom+, HexaMotion supports verification of motion-managed treatments, including tracking, gating, and other techniques where motion can affect treatment delivery.

What our customers say
When selecting a QA system for pre-treatment dosimetry, reliability, speed, efficiency, and minimal setup time are key. Delta4 Phantom+ meets all these criteria while also offering high spatial resolution and the ability to measure in two orthogonal planes. The fact that it’s wireless is a great advantage, and the innovative design—eliminating the need for an angle sensor—makes measurements even easier. Additionally, having an independent dose calculation system with a Monte Carlo algorithm ensures confidence in treatment accuracy.
In radiotherapy, confidence in every treatment delivery stems from rigorous patient-specific QA. With the right QA tools, we verify accuracy and enhance trust in the precision and safety of each patient's care, giving clinicians and patients the utmost confidence in the treatment outcome. From a physicist's perspective, the Delta4 Phantom+ is one of the best QA tools available.
When implementing the Accuray Radixact® with Synchrony®, it became obvious to us to invest in the Delta4 HexaMotion. This solution was the best choice in order to control treatments of moving targets with excellent precision. We have been performing IMRT / VMAT treatments since 2011 as well as stereotaxic treatments on various machines. The advantage of the Delta4 is that it is a detector that is compatible with all these equipment. Its 3D representation of the measured dose is a real advantage. We find in Scandidos products what could characterize the Nordic spirit: simple and effective!
Letting the Delta4 HexaMotion with the Delta4 Phantom+ move realistically- be it a respiratory cycle of a patient´s breathing, or even a prostate system where it’s random omni-static placement, I can only do it with the Delta4 solution. No other solution has that capability and without it, I would be unable to safely deliver the treatment to the patients..
As a Clinical Scientist, I value the straightforward, meaningful data that Delta4 provides. The new wireless functionality of the Delta 4 Plus makes it so quick and easy to use, it’s even been described by one member of staff as ‘an absolute dream’.
The Delta4 Phantom+ MR is quick and easy to use and gives us confidence that our treatments are delivered just as they are intended.
After good results of a number of tests, we decided to expand our existing Delta4 Phantom+ portfolio with the MR-compatible Delta4 Phantom+ MR.
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.
We are very much looking forward to using the MR-compatible Delta4 Phantom+ at our Viewray MRIdian Linac as well as at our Elekta and Tomotherapy Linacs to further advance and streamline our patient QA.
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.
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.
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.
The service agreements with Scandidos give us peace of mind, knowing that we have reliable support whenever we need it. This allows us to maintain the high standards of our work and deliver consistent results, knowing that our equipment is always in top condition.
Scandidos Support is incredibly responsive, even across different time zones, and always offers constructive contributions to solve problems. They approach every interaction with a friendly and helpful demeanor, no matter how big or small the issue may be. If a solution cannot be found immediately, they work closely with the user to identify the quickest and most efficient path forward, minimizing downtime.
By using the Delta4 Discover during treatment we can confirm the actual dose in the patient. The real-time dose verification from the Delta4 Discover plays an important role when physicians do treatment planning. They can adapt the plan if they find out that any errors have occurred during treatment.
Thanks to the Delta4 Discover´s ability to detect errors immediately after treatment, we can perform treatments without any stress or extra efforts like recalculations.
When implementing the Delta4 Discover it was a very simple characterization process, we did not have to do beam modeling and the automated interfacing with the R&V system enabled a seamless workflow. It is not time consuming in our daily routine and we intend to use it continuously in all treatment fractions, and also use it for our SBRT treatments and implement it in our Machine QA program.
