Daily QA 3 - QA Accelerated
An Advanced Tool for Daily Quality Assurance of a Radiation Therapy Beam.
Daily QA 3 Hardware
Daily QA 3 has 25 detectors and uses both ion chambers
and diode detectors to optimize measurement results:
- Twelve diodes with an active detection area of only 0.64
mm2 measure light:
Radiation field coincidence for a 20 x 20 cm file at 100 cm SSD
- Five 0.6 cm3 ion chambers measure output, flatness, axial
symmetry, and transverse symmetry.
All chambers are vented, and temperature pressure is automatically measured by the instrument and
applied to the readings.
- Four ion chambers with inherent buildup measure electron energy.
Each chamber has a different
amount of attenuation built into the top plate. No flipping or additional buildup is required.
- Four ion chambers measure photon energy. Uniquely "curved"Ã‚Â ion
chambers were chosen for
this test to minimize beam edge measurement area. Streamline energy measurement does not
require changing buildup between energies or flipping the device.
Daily QA 3 Software
The instrument operates with Windows application software which runs on the user's computer.
Data collected and the results are stored in an advanced user-editable database for real-time
trending and is accessible via the network. Daily use is extremely simple, yet sophisticated
analysis options are available with the click of a mouse.
Customized User Interface
Daily QA 3 software allows the Physicist to define their
own unique QA requirements. The highly versatile
system results in a "scheme tree"Ã‚Â, which is a list of machines and tests scheduled for the selected date.
Once the scheme tree is set up in the software, daily measurements are automated and involve 3 simple steps.
At the end of each measurement a status bar will turn either green or red indicating if the test passed
Trend Analysis Database
The database provides a graphical presentation of measured and calculated data for each template as a
function of time. Graphing the parameters gives the user a means to visualize trends emerging in
the beam output.
Daily QA 3 reports can span any defined time-frame and are
suitable for presentation.
