Preface Intended Use The Daily QA 3 is intended to measure and analyze the daily radiation output characteristics of an external treatment machine (linac or Cobalt 60) before the start of daily treatment in a radiation oncology center, and not for calibration of said machines.
CAUTION: Certain federal laws restrict this device to sale by or on the order of a qualified radiation therapy professional, such as a medical dosimetrist, medical physicist, or radiation oncologist.
Application Every morning, the Daily QA 3 is positioned in a standard beam setup for measurement. The parameters measured are: dose output, beam symmetry, beam flatness, beam energy, and light/ radiation field coincidence. These parameter measurements are compared to a reference value using trend graph analysis in the Daily QA 3 software. If a measurement exceeds an action level, an investigation of the cause will take place before treatment resumes for the day.
WARNING: Do not modify a patient’s treatment plan based only on the results from a single QA device; but DO investigate the source of the error in the treatment delivery device (TDD) or treatment planning system (TPS).

Introduction
Description Daily QA 3 captures the “beam print” of a radiation field by measuring radiation using ionization chambers and diodes, arranged in a fixed pattern such that a reproducible setup will reveal changes in beam characteristics. Trend analysis is performed with built-in database software. Daily QA 3 software stores measurement results in a database that allows trend analysis of measurements and report generation. The database can be centralized so that any network computer running the Daily QA 3 client software can access the data. Daily QA 3 software can also be used with PROFILER 2, TomoDose, and Daily QA Check 2. For a list of software differences when using other instruments, see the Daily QA 3 Reference Guide or the software Help Index.

Calibration The Calibration menu contains five items ordered in a logical sequence that should be followed when using Daily QA 3 software. •
Calibrate Temperature and Pressure – See Calibrate Temperature and Pressure – Daily QA 2 and Daily QA 3 on page 8.
•
Calibrate Absolute Dose – See Calibrate Absolute Dose on page 8.
•
Calibrate Array – See Calibrate Array on page 9.
•
Calibration Management – This function enables import and deletion of qualifying array calibration files and can be performed as needed.See the Daily QA 3 Reference Guide or the software Help Index for details.
•
Export DQA 3 Calibration (for Argus) – This function is used to export an array calibration as a text file for Argus. For information about exporting a Daily QA 3 calibration for Argus, see the Daily QA 3 Reference Guide or the software Help Index.
Calibrate Temperature and Pressure – Daily QA 2 and Daily QA 3 Air density corrections derived from temperature and pressure sensors in the Daily QA device have a direct influence on output measurements, thereby influencing the Dose Calibration Factor of the central axis chamber (CAX). When the Daily QA 3 software is upgraded to version 2.5, the temperature and pressure sensors for each Daily QA 3 device must be calibrated using your temperature and pressure standards as a reference. These reference standards should be the same as those used for dosimetry calibration, thereby enabling a future intercomparison to your dosimetry standard. Any new or replacement Daily QA 3 instruments must also be calibrated for temperature and pressure prior to calibrating the absolute dose response. For more information, see the Daily QA 3 Reference Guide or the software Help Index. 1
From the menu, select Calibration > Calibrate Temperature and Pressure.
2
In the ‘Calibrate Temperature and Pressure’ dialog box, enter actual ambient temperature, to tenths of a degree, obtained from a calibrated thermometer in treatment room.
3
Enter actual pressure, to tenths of a unit, obtained from a calibrated pressure gauge in treatment room and click Apply.
Calibrate Absolute Dose This function converts the CAX ion chamber data from device response to dose. The air density corrections are part of this calibration, therefore the calibration of Temperature and Pressure will influence the CAX dose reference value. The Absolute Dose Calibration results in an Absolute Dose Calibration Factor, or Dose Factor, for short. The Dose Factor, a new database field in version 2.5 labeled as ‘AB_DOSE_CF’, is applied globally to all template measurements for a given device, hence the user will only perform the 'Calibrate Absolute Dose' function for a single energy per machine. For information about calibrating absolute dose, see the Daily QA 3 Reference Guide or the software Help Index.

Section 3. Software Setup
Absolute Dose Calibration Procedure 1
Set up the Daily QA 3 using a known absolute dose value for a given MU, field size, depth, and SSD. Note: Water equivalency from the top of the Daily QA 3 instrument to point of measurement is 1.0 cm. The physical distance from the top of the Daily QA 3 instrument to the point of measurement is 0.74 cm.
2
Select Calibration > Calibrate Absolute Dose. In the Available Devices panel the highlighted serial number is the device connected. The instrument image on the right shows the correct orientation for the measurement. Note: The Calibrate Absolute Dose function is only performed for a single energy per device. The resultant Dose Factor is automatically applied to all other energies for that device.
3
Click Start and deliver the MU for the known dose. Follow the instructions on the screen to complete the dose calibration. For additional details, see the Daily QA 3 Reference Guide or the software Help Index.
Calibrate Array This procedure is for Daily QA 3 only. For PROFILER 2 and TomoDose, use the separate instrument software to perform array calibration then import the resulting array calibration files into Daily QA 3 software. For details, see the Daily QA 3 Reference Guide or the software Help Index. If calibrating an array with an Elekta Beam Modulator™ linac limited to 16x21 cm field SAD, see the Daily QA 3 Reference Guide or the software Help Index for additional information. 1
For photons, adjust collimator jaws to 25 x 25; for electrons, install 25 X 25 cm cone.
2
From the menu, select Calibration > Calibrate Array…” The ‘Calibrate Array’ dialog box displays the Daily QA 3 as it should be oriented for the first array calibration measurement and prompts for the energy and beam type. To zoom in and change perspective, click the magnifying glass at the top right of the screen.

Create a QA Test Plan, Site, Room, Machine, Template Overview Note: Screens in this section show Daily QA 3 only; other device screens have a slightly different appearance. The QA test plan is a Scheme Tree that contains all the test and schedule details. As viewed in QA Mode, the Scheme Tree lists the sites, rooms, machines, and tests; it is linked to a calendar so that recurring tests appear on the days scheduled. Once the device is connected and setup for the test in the Scheme Tree, then as each test is completed, measurement data is stored in the database and the software advances to the next test. Test results are reviewed in the Trend Mode.

To edit an existing template, select the template in the Setup Overview panel, and then click Edit in the Template Information panel.
Baseline Options Consider the following when selecting the baseline options for a template. •
Absolute mode evaluates results for axial symmetry, transverse symmetry, field size and field shift against a field with perfect symmetry and size.
•
Relative mode evaluates results against the measured baseline. If you are only interested in deviations from the baseline, use relative mode.
Example: During baseline measurement, if a beam has an axial symmetry of -0.6%, and a daily QA measurement a week later has an axial symmetry of -0.5%, then in absolute mode, it will show an axsym of -0.5%, but in relative mode it will show an axsym of +0.1%.
Baseline QA Template Before using a QA test template, it must be baselined with a QA measurement. All trend parameters are compared with the baseline data set until a new baseline is established. Each time the QA template is baselined, subsequent data is compared to the new baseline data, while all previous data is compared to the previous baseline. 1
From the Daily QA 3 software menu, select Setup > Baseline QA Template.
2
The QA Template Baseline Instructions form appears. Follow the onscreen instructions to complete the baseline procedure. See the Daily QA 3 Reference Guide or software Help Index for more detailed information. The baseline dose corresponds to the value that will represent your desired output baseline. For example, after an output measurement the Daily QA 3 software will subtract the baseline dose from the output measurement to calculate the percent difference. Suppose your output measurement is 102 and you entered 100 for your baseline dose; your percent difference for that output measurement would be 2%. The delivered dose on the other hand allows you to compensate for situations when you know the output of your machine is different from your desired baseline dose. For instance, if you want your baseline dose to be 100 (1.00 cGy/MU), but you know the current output of your machine is 2% hot (1.02 cGy/MU), enter 102 as your delivered dose. These two factors allow you to separate the value used as a baseline from the actual process of taking a baseline measurement.

QA Measurement
Preparing for Measurements To maintain a stable temperature, the instrument should remain powered on at all times, connected to power via the PDI 24 hours per day. Store the instrument in the treatment room, but not in a location where a primary beam may occur. If the Daily QA 3 is powered off, power it on and allow it to warm up for 10 minutes before using.
CAUTION: After charging an rf-Daily QA 3, allow electronics to cool down at least 15 minutes before making measurements. For more information about preparing for measurements, see the Daily QA 3 Reference Guide or the software Help Index.
Measurement Screen illustrations, orientation illustrations, and detector layouts in this section show Daily QA 3 only. When connected to other instruments, screens have a slightly different appearance. See the Daily QA 3 Reference Guide or the software Help Index for more information about QA measurements. 1

•
Power/data cable is connected to the base station, base station is on a table or shelf out of direct beam, and non-connector end of the base station points toward the Daily QA 3 instrument.
CAUTION: Never place the base station in the direct beam. Direct radiation will damage the base station and void the factory warranty. 4
Set up exposure parameters on the linac to match values under Machine Setup (C).
5
Ensure Background text box on DAILY QA 3 toolbar displays Yes. If not, click Background and perform a background manually. See the Reference Guide or the software Help Index for instructions.
6
Click Start (D) and deliver the prescribed dose for the template. The beam status displays in the Status box in the DAILY QA 3 toolbar.
7
When the beam turns off, review the ‘Results’ panel. Values are color-coded: green = all passed; red = failure levels; yellow = values that fall between warning and failure levels. If desired, enter comments about the test in the Measurement Notes text box.
8
To adjust an output value, apply a correction factor to the measurement by clicking Template Dose Correction (E). The ‘Template Dose Correction’ dialog box opens. Enter the target dose and click Apply. The correction factor is applied automatically. For more information about the Template Dose Correction, see the Daily QA 3 Reference Guide or the software Help Index.

Support and Maintenance
Maintaining Hardware Repair There are no user-serviceable components in the Daily QA 3 or the Power Data Interface (PDI). If there are problems with the devices, contact Sun Nuclear. See Contacting Sun Nuclear Support on page 19.
CAUTION: Do not open the housing unless you are performing an upgrade that has been approved by Sun Nuclear Corporation. If the Daily QA 3 housing or casing is damaged such that the device integrity is compromised, return the device to Sun Nuclear Corporation for repair. Inspect cables periodically for damage. Return damaged cables to Sun Nuclear Corporation for repair or replacement if any mechanical or electrical degradation is suspected. Additional service information is available on the Sun Nuclear web site: www.sunnuclear.com/support
Cleaning Clean the instruments with a soft dry cloth. Do not use liquid cleaners, solvents, or abrasives.
Storage Store the instrument in an indoor, protected environment where the instrument will not be irradiated by the direct beam.
Disposing and Recycling The Daily QA 3 instrument contains electrical components. In some countries the disposal of electrical components is subject to special requirements. When the components are no longer functional or are otherwise ready to be discarded, recycle or dispose of them according to local waste management or recycling regulations.
Minimizing Radiation Damage Although detectors are designed to be exposed directly to the beam, the electronic processing circuits can be damaged by direct exposure to ionizing radiation. The electronic circuits are located in the raised end of the instrument behind the line that is labeled “KEEP DIRECT BEAM ABOVE THIS LINE”. To minimize damage to electronics: • Never allow any direct radiation beyond the “KEEP DIRECT BEAM ABOVE THIS LINE” mark on top surface of device. • Never expose electronics portion of instrument to beam. • Never leave the device on couch during warm-up. • Never store device where it can accidentally be irradiated, such as a shelf in the treatment room that is irradiated by the beam when the linac is rotated. • Avoid frequent use of thick buildup that may cause scattered radiation that will damage the electronics. Note that adding extra buildup is not normally necessary for daily QA measurements and may increase the scattered radiation to the electronics. Note: The Daily QA 3 firmware cannot be upgraded if the device is connected wirelessly.

Troubleshooting Daily QA 3 Troubleshooting Indication Software does not recognize instrument
Probable Cause Not properly connected to USB port.
Remedy Check USB cable connection to PDI and PC.
Wrong operating system. Must be Windows 10 or Windows 7.
Data appears incorrect
USB drivers not set up correctly.
Reinstall client software. The correct USB drivers are installed with software.
Wrong calibration file.
Use correct calibration file.
Improperly calibrated.
Recalibrate.
No background collected.
Manually collect background and repeat measurement. See the Reference Guide or the software Help Index for instructions.
Conditions changed since background taken. A QA measurement reports 0.00 cm field size
Possible cause: • Setup error. • Electron field size calculation for Daily QA 3 is sensitive to array calibration, so you may need to acquire an array calibration for the specific energy.
Screen display size is incorrect Monitor’s DPI setting is wrong. rf-Daily QA 3 battery is not charging
16
• First, rule out a setup error, such as a slight shift or wrong SSD or linac energy. • If correcting setup doesn’t resolve the issue, acquiring an array calibration for the specific energy may result in a more accurate field size since electron field size calculation for Daily QA 3 is sensitive to array calibration. • If it is impossible to determine field size with a particular cone/linac system, Sun Nuclear recommends examining relationships between the diode detectors that straddle the 20 cm field marks for a commissioned system, and then baseline QA measurements from those relationships. Edit the monitor properties and set it to Normal size (96 DPI). Contact your IT department if you need assistance.
The instrument is stored To reset the charge circuit and allow the device to off AC power for an begin charging again, apply AC power, then lightly extended period of time press and hold the recessed override switch for 3 seconds using a pointed, non-metallic object.

CAUTION: bInterference may occur in the vicinity of equipment marked with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies. NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device. b. Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
