The innovative Delta4 Discover transmission detector provides confidence and patient safety based on real time measurements. Its outstanding accuracy and ease of use assures the highest efficiency in your QA process.
Safety for the patient at-treatment
The Delta4 Discover monitors with high accuracy the dose that is delivered to the patient. It automatically compares the delivered dose with the planned dose. The patient and the clinic can be ensured that the treatment is delivered precisely and safely.
Express Measure automatically and independently verifies:
- Monitor Units.
- MLC leaf position.
- Gantry and Collimator Angle.
- Patient position.
The system is easy to implement and doesn't require recommissioning.
The Ultra-thin Delta4 Discover detector uniquely gives you:
- Maintained clearance.
- Beam transparency: The attenuation is less than 1%.
- Minimal skin dose: less than 1% additional skin dose.
- Highest resolution: Verify the MLC leaf position with sub-millimeter accuracy.

The Wireless Phantom
The Delta4 Phantom+ system offers the most accurate and most efficient verification of your IMRT, VMAT and TomoTherapy plans.
Now Completely Wireless
- Integrated Wi-Fi and Battery operation keeps all cords away
- New generation stable p-type detectors eliminates re-calibration
- Absolute dose also available with ion chamber
- Easy to move from trolley to couch with no lifting required
- Measure where it really matters - detectors in the target region
- Instant approval of plans
The Delta4 Phantom+ system is the only system that actually measures the dose distribution in the isocentric region. You can thereby instantly approve the plans as you know how much dose that is delivered in the target and the OAR's.
Water equivalent dosimetry
The Delta4 Phantom+ is also available in Plastic Water® which allows you to perform your patient plan QA consistent with the dosimetry protocols TG-51 and TRS-398. Your QA can now be performed without scaling artifacts due to density and correct scatter from materials with higher densities.
- Highest accuracy in dose determination
- Water equivalence in diagnostic and therapy range

Target motion management QA in 6D
The success of gating and tumor tracking requires rigorous QA and validation to meet the goal of better coverage of the target and sparing of organs at risk. The HexaMotion 6D Motion Platform uniquely uses the patient specific tumor motion pattern and replicates it in 6 dimensions.
- Verify the dose in moving targets
- Which patients will actually benefit from target motion management
- Study the dosimetric effect of motion per patient structure
- Detect any latency in the delivery system
- Fast positioning within sub-millimeter accuracy
Analyze the dose delivered in the patient anatomy
With the Delta4DVH Anatomy software option you can verify and analyze the dose that has been delivered to the patient anatomy. Based on the measurements in the isocentric target region and dose calculation of the dose in the patient anatomy you now have a truly independent verification of the delivered dose.
- Delivered dose directly in the patient anatomy
- Independent from the TPS and the delivery system
- Use initial CT or fraction Cone-beam CT data
The Delta4DVH suite offers full 4D analysis in both Phantom and in the Patient Anatomy.
The Professional version includes an automated analysis in 4D with customizable acceptance criteria.
Perform QA for Advanced RT in a few minutes
With modern advanced RT technology there are more stringent requirements on the accelerator performance. The Delta4 MachineQA software option for fast Data Acquisition and Advanced Data Analysis allows you to perform QA with respect to rotation, start-up behavior and dynamic beam modulation.
You can easily define test sequences that allows you to perform extended accelerator QA for IMRT and VMAT in only a few minutes. Tasks that with other methods can take up to hours to perform during the monthly QA.
Delta4 Machine QA software option allows:
- Advanced machine QA done in few minutes
- Stability check with high accuracy and detailed analysis
- Beam constancy at various gantry angles
- MLC picket fence test at various gantry angles
- Discover and track long-term effects and trends
With the C-shaped Delta4 Trolley, the phantom slides in over the couch for quick and easy positioning of the phantom in the desired measurement position.
