Fastest, most Accurate and most Reliable Linac commissioning and regular QA

Quality beam scanning is the cornerstone for treatment planning and delivery accuracy. The Blue Phantom², with its scanning software myQA Accept, is the leading water phantom solution for radiation therapy (RT) beam scanning. The system’s unique design facilitates faster and more accurate commissioning of RT treatment systems which is fundamental for safer patient treatments.

The latest Blue Phantom2 is based on over 40 years of experience during which IBA Dosimetry has been providing high quality dosimetry equipment and services to more than 4,000 satisfied water phantom users worldwide.

"The main things I look for in a scanning system are positional accuracy, reproducibility, and stability. The folks at IBA Dosimetry definitely got it right with this one. The typical potentiometers and stepper-motors of other systems are replaced with contact-less absolute measurement sensors. This ingenious piece of engineering provides 0.1 mm accuracy, ± 0.1 mm reproducibility, and unsurpassed long-term stability. Over 20 years, I have used many systems from many vendors. This is by far the best."

IBA Dosimetry Testimonial Matthias Dierl

Mathias Dierl
Head of Medical Physicists / Clinical Center Bayreuth, Germany

"The Blue Phantom² scanning system with myQA Accept and Stealth Chamber™ are the perfect combination for fast data collection! I was really surprised how easy it was to attach the Stealth Chamber™ to the LINAC with no need to change or reposition the chamber during the whole commissioning process. This saved us a lot of time. The scan results and the excellent reproducible reference signal quality absolutely satisfied all my needs!"

"I have been using IBA's Blue Phantom and the innovative linear diode array during the commissioning of my Trilogy and Novalis TX LINACs. The capability to acquire profiles instantly, allowed me to collect all beam data in a fraction of the time. The speed of the Linear Diode Array versus a single detector is unmatched in the industry."
