myQA SRS - Troubleshooting

  • Updated

With some Ethernet adapters, the connection is not stable to the device, especially for longer measurements ( 30 min). When this problem occurs, please execute the following steps:

  • When using a laptop, ensure that it is plugged in to a power supply, and the network cable directly plugged to internal network card of the PC (no docking station, no USB adapter, etc.).
  • Restart Windows
  • In myQA > myQA > Platform Equipment setup, select the myQA SRS, Change Network address to “localhost”.
  • Go to Windows Control Panel – Network and Sharing Center – View network status and tasks – Ethernet. Open the Ethernet Properties dialog, and check that the NIC setting, eBUS Universal Pro For Ethernet Driver, is active.

  • In the Windows Start menu, start device manager by typing “device manager”. 
    Follow the procedure described in Section 4.1.2 and check and ensure the NIC settings are: 

    • Numbers in the Value box for Receive Buffers and Jumbo Packet are set to the maximum values o
    • Interrupt Moderation Rate is set to “High” 

    If the above procedure does not help, please visit the following website for more detailed information or contact the IBA Customer Service (see contact information in Chapter 10).

Device Locations and Connections

Location and connection of the myQA SRS detector

Note: Only direct connection between the detector and the PC is applicable.

 

 

Cable connections

  • Plug one end of the network cable to the myQA SRS device and the other end to the PC.
  • Plug the DC power supply to the mains power.
  • Plug the DC power supply to the myQA SRS device.
  • Switch on the device by pressing its power switch. The green LED ring should light up.

 

Spacers

To ensure spatial accuracy of measurements with the myQA SRS Phantom (V1), IBA Dosimetry has developed spacers that can be adhered to the myQA SRS detector and compatible Film and Chamber Inserts. These spacers will ensure no shifting or sloping occurs when the detector or inserts have been inserted into the phantom.

The spacers for the bottom and sides of the detector / inserts are available in 0.1 mm, 0.2 mm, and 0.3 mm thickness. A feeler gauge has been provided to measure the gap width between the phantom and detector / inserts.

 

IMPORTANT NOTICE: USE CAUTION WHEN MEASURING THE GAPS 

  • The feeler gauge should easily slide in and out of the gap. Do not force the gauge into the gap or the surface of the phantom / detector / insert may be damaged.
  • The detector / insert should fit securely but not tightly in the phantom. If it is difficult to fully insert the device, then the spacer is too thick. It is recommended to use two people to measure the gaps of the myQA SRS detector.

 

  • Measure the Insert gaps 

    Place the insert into the phantom and, starting with the thinnest blade, slide the feeler gauge into the gap at the top and side of the insert. When measuring the side, push the insert all the way to one side and measure the gap. The measurement obtained from that gap should be halved to determine what spacer will be needed for both sides.
     

    Examples:

    • If the side gap is 0.2 mm, then a 0.1 mm spacer will be needed for both sides.
    • If the side gap is 0.5 mm, then use a 0.2 mm spacer for one side, and a 0.3 mm spacer for the other.

  • Measure the myQA SRS detector gaps

    With one person holding the detector, partially slide it into the phantom body cavity. Ensure the bottom of the detector is in contact with the bottom and one side of the phantom cavity. There should be enough space to easily slide the gauge into the top and side gaps.

  • Apply the spacers

    Place the spacer with the appropriate thickness on the detector / insert. Please note that upon application, if the spacer is not properly aligned, it is recommended to remove and reapply the spacer immediately. The longer the spacer is on the detector / insert, the more difficult it is to remove.

    For the myQA SRS, special side spacers have been provided with a window for the alignment markers. Please be careful and apply the side spacers with the correct orientation so the alignment markers are not covered.
