Fast, Reliable Daily QA

Standard Imaging's expertise in ion chambers, phantoms and electrometers is the foundation for the innovative QA BeamChecker Plus. Integral build up and automatic energy detection allows the QA BeamChecker Plus to operate independently from its QA management software without the use of wires or cables. Radiation Therapists do not need to enter the vault between energies, allowing for fast, intuitive morning QA in up to 9 treatment rooms.

Features & Benefits

Automatic Energy Detection

Measure energies in any order and automatically detect energy type, begin measurement, apply corrections and display results.
Data is automatically saved and the device readies itself for the next energy within 10 seconds for the fastest QA on the market.

Software-Free Operation

Does not need to be controlled via PC, allowing for immediate pass/fail results.
No cables, no wires, no hassles, download data later allowing for easy trending and reporting.

Wireless Operation

Versatile for wireless, real-time data collection using software interface and instantaneous measurement results.
Fast, rotational QA is ideal for IMAT, VMAT, TomoTherapy and dynamic wedge tests.

How It Works

Setup

The QA BeamChecker Plus creates baselines for each photon and electron energy or multiple plans for static and dynamic exposures of different jaw widths. Once established, the QA BeamChecker Plus can perform Wire-Free daily QA. Unlike competing daily QA instruments, no software is required beyond this initial step.

Software-Free Daily QA

The QA BeamChecker Plus is placed on the treatment couch in same position as during the baseline measurement. The patient camera is aimed at the QA BeamChecker Plus front panel. Any energy for which a baseline exists can be administered as the order of exposure does not matter. Upon beam detection, the display identifies the energy and indicates a “pass” or “fail” compared to the baseline. The measurement is automatically saved and can be viewed later in more detail. If real time measurements are desired, use the wireless software interface for instantaneous measurements.

If the energy passes, the QA BeamChecker Plus automatically resets after a brief period and readies itself for the next exposure. Once all energies of one type are completed, the unit is simply flipped over to utilize the appropriate integrated build-up. 1.5 cm of water equivalent build-up is provided on the electron side, 3.5 cm on the photon side.

Export

When the routine is completed, the QA BeamChecker Plus is placed onto its included cradle for a recharge and link to the PC. Periodically, QA data can be transferred to a database for trending and analysis.

"BeamChecker is a great device. For the therapist there is no software or cables that need to run every morning. This allows for quick and easy warmups. With the customized options we can check wedge placement and a VMAT test case every morning. BeamChecker is a smart and simple device. We have been using it since 2012 and are very pleased with its performance."

Ben Robison Medical Physicist Provision Radiation Therapy

“The QA BeamChecker has been a reliable and easy to use morning QA device for our cancer center, and a welcome upgrade for our entire team. Our therapists appreciate the setup simplicity in the early morning, our physicists trust the output results, and our management team values us starting the day on time while ensuring patient safety.”

Kayla Kielar, PhD Medical Physicist Dorothy E. Schneider Cancer Center

"My therapists threatened to mutiny if they weren't allowed to buy the QA BeamChecker Plus."

Michael J. Tallhamer Medical Physicist Rocky Mountain Cancer Centers

"We have the QA BeamChecker Plus at three sites. It is the best device I have used in 25 years as a medical physicist."

Al Foster, PhD Senior Medical Physicist IU Health Ball Memorial Hospital

"When it came time to purchase a new daily check device, we chose to try the QA BeamChecker based upon Standard Imaging's reputation for producing well-designed, quality equipment. During our demo period, we were impressed by the design, ease of use, and quality of construction. Comparing it to our previous device, we save an average of 20 minutes on our daily procedure. Given the choice, our users unanimously chose the QA BeamChecker over other manufacturers. Since then, we have purchased QA BeamChecker Plus units for four of our other centers and will look to Standard Imaging for further daily check device purchases."

Kurt Stump Ph.D., DABR Medical Physicist Santa Maria Radiation Oncology Medical Center

"We replaced our 7+ year-old BeamChecker Plus daily QA device from Standard Imaging with a new BeamChecker Plus, not only because of its technical specifications, but also because of the great technical support we get from SI."
