Delta4 Phantom+

The fastest and most accurate 4D verification system

The Delta4 Phantom+ offers unmatched accuracy and efficiency for verifying advanced radiotherapy treatment plans, including IMRT, VMAT, Halcyon, SRS, SRBT, Radixact, and TomoTherapy.

Unlike single-plane systems, Delta4 Phantom+ measures 4D dose distribution in the isocentric region, providing comprehensive 4D insights for confident verification of even the most complex plans.

With patented dual orthogonal detector planes and advanced detection technology, the Delta4 Phantom+ streamlines plan verification, saving time and resources without compromising accuracy.

Meets the TG-218 requirements

Verifies IMRT, VMAT, Halcyon, SRS, SRBT, Radixact and TomoTherapy plans with unmatched precision

One system for patient QA and machine QA

Delta4 Software

Instant and powerful 3D dose analysis

Instant results

Obtain instant and accurate radiotherapy QA results with the Delta4 software. Dose deviation, Distance-to-Agreement (DTA), and Gamma Index are instantly available—no further processing required. Customize QA reports to meet your specific clinical needs.

Powerful analysis

Leverage unique 4D dose measurements to analyze delivered dose by fraction, beam, or control point. Analyse delivered 4D dose within the patient's anatomy using the Delta4DVH software suite, providing unique tools to assess the clinical significance of any dose deviations.

Delta4 Software

Instant Results

Instant display of dose deviation, distance to agreement, gamma pass rate, and plan pass/fail status.

Wide range of analysis tools including profile display, isodoses, structure overlaying, continuous dose display, and dose-volume histograms.

Possibility to calculate continuous dose distributions within the patient.

Testimonials

What our customers say

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.

Amit Nirhali Chief Medical Physicist and RSO at Sahyadri Super Speciality Hospital, Pune

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’.

Karen Hawthorn Clinical Scientist, Newcastle upon Thyne Hospitals NHS Foundation Trust

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.
