The Delta4 Family is the complete solution for both Pre Treatment and At Treatment dose verification covering all modern treatment technologies VMAT, IMRT, SBRT, 4D-RT and TomoTherapy. Being the only system that actually measures the dose distribution in the isocentric region, you can be confident that the dose delivered to your patient also is what you had planned.


  • Delta<sup>4</sup> Phantom+

    Delta4 Phantom+

    A wireless system that offers accurate and efficient verification of your IMRT, VMAT and TomoTherapy plans. This is the only system that actually measures the dose distribution in the isocentric region. Featuring: Integrated Wi-Fi and Battery operation keeps all cords away New generation stable p-type detectors eliminates re-calibration Easy to move from trolley to couch with no lifting required Absolute dose also available with ion chamber The Delta4 Phantom+ is also available in Plastic Water® (a registered trademark of CIRS Inc), consistent with the dosimetry protocols TG-51 and TRS-398. + info
  • Delta<sup>4</sup> Discover

    Delta4 Discover

    An elegant detector that fits perfectly in the Gantry, the Delta4 Discover accurately monitors the dose that is delivered to the patient. It automatically compares the delivered dose with the planned dose and independently verifies: Monitor Units, MLC leaf position, Gantry and Collimator Angle and Patient position.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 system is easy to implement and doesn't require recommissioning. + info
  • Delta<sup>4DVH</sup> Anatomy

    Delta4DVH Anatomy

    With the Delta4DVH Anatomy software option you can verify and analyze the dose that has been delivered directly in the patient’s 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. + info
  • Delta<sup>4</sup> Machine QA

    Delta4 Machine QA

    The Delta4 MachineQA software allows you to perform QA with respect to rotation, start-up behavior and dynamic beam modulation. Enabling: 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 + info
  • Hexamotion


    The 6D Motion Platform uniquely uses the patient specific tumor motion pattern and replicates it in 6 dimensions enabling for dose verification in moving targets, dosimetric study of motion effect per patient’s structure and latency detection in the delivery system. With the HexaMotion 6D Platform you may also assess which patients will actually benefit from target motion management. + info
  • Delta<sup>4</sup> Trolley

    Delta4 Trolley

    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. + info
