Setup for CCU-X

Ports necessary for full functionality of CCU-X:

TCP: Port 1338 outbound towards CCU-X (HTTPS)
UDP: Port 5353 inbound from CCU-X (multicast DNS)

Note: Additional information on the CCU-X device can be found in myQA Blue Phantom3 Instructions for Use.

CAUTION: NETWORK SECURITY
If the CCU-X is connected to a clinical network, the healthcare provider shall ensure that network protection measures are in place protecting the network from unauthorized access.

WARNING: CCU-X TLS CERTIFICATE NOT CHECKED BY MYQA ACCEPT
The TLS certificate of the CCU-X is not checked by myQA Accept. This could allow an attacker with access to the network to place a rogue device to hijack the connection and intercept traffic between myQA Accept and CCU-X (e.g., by issuing mDNS responses faster than an original CCU-X, causing myQA Accept to connect to the rogue device rather than the original CCU-X).

CAUTION: PHYSICAL ACCESS CONTROL (OPERATION AND STORAGE)
The health care provider shall ensure that the device is not kept in public spaces. Access to the premises where the device is located, shall always be controlled by appropriate technical / organizational means (e.g., using badges).

If the SW cannot receive the CCU broadcasting, or the CCU subnet is not on same subnet as the host PC (CCU-X only), or the CCU is not online, you can only connect it to myQA Accept manually:
Click New.
Enter the serial number, IP address, and port number in the Manual Controller Parameters dialog.
Click OK.

CCU-X Calibration

WARNING: NO CALIBRATION PROCEDURE FOR THE TEMPERATURE AND PRESSURE
Currently there is no calibration procedure for the temperature and pressure readings provided from the water phantom and CCU-X, therefore, automatic kTp correction must not be used for absolute measurements. Using the kTp correction for absolute measurement might lead to flawed measurements and potentially patient harm. kTp correction should only be used when performing relative measurements.

See Section 4.2.1.5 for information on manually entering calibration information for detectors.

CAUTION: REGULARLY CHECK ADCL CALIBRATION
For point dose measurements (IEC 60731) regularly check the field electrometer's ADCL calibration. Do not perform point dose measurements (IEC 60731) with an ADCL calibration older than two years. Performing measurements with a calibration older than two years might lead to inaccurate measurements not complying with IEC 60731 standards.

Servos / Scanners

Open the window by clicking Equipment > Servos / Scanners.

Equipment Setup – Servos / Scanners

In the Measurement Device group, select the devices that will be in use from the drop-down list and click the Install button. The devices will appear in the Installed Devices. The selected device in the list of Installed Devices will be the one used by default.
Water Correction Depthwill be displayed automatically according to the chosen device in the Installed Devices box. It is used to compensate the measurement depth for the rise of the water surface (1) due to submerge of the motors.

1: Motor, 2: Detector, 3: Water surface

If d ≤ w: correction = d * c/10000,

If d > w: correction = w * c/10000,

where,
- w: the distance from the top of the motor to the detector position.
- d: the distance from the water surface to the detector position.
- c: the water correction factor determined by the area of the selected phantom. It is stored in the device template.
Once the water surface position is saved, automatically, the water correctionwill be calculated, and the depth position will be compensated.

For Blue Phantom Helix, water correction factor is only valid when using designated detector holders.
In the Device Turn Angle group, you can define the orientation of the servo / scanner placement under the accelerator. It is important not to interchange the crossline direction with the inline direction.

Detectors

To define the detectors, click Equipment > Detectors to open the Detectors page. It contains five groups: Installation, Calibration, Effective Point of Measurement and Geometry.

Caution! : Limitation of the Stealth chamber

The use of the Stealth chamber is only recommended for energies between 6 and 10MV, and for field sizes up to 150 mm × 150 mm.

Installation group (1)

The SW provides a set of detector templates. The template contains the some properties of a detector (see the table below) that cannot be edited but for display (1a).

The table below lists the detector properties related to the in myQA Accept core and SMARTSCAN wizard applications.

The SW provides a set of detector templates. The template contains the some properties of a detector that cannot be edited but for display (1a).

Please see Table 4.3. Detector properties in the detector template in the myQA Accept SW in Section 4.2.1.5 Detectors - Installation Group, myQA Accept Installation Guide.

Procedure to install a detector in the SW:

Chose a detector from the Templates dropdown box, e.g., a CC13 is selected. If the detector is not in the Templates, select a similar one and then edit it as needed.
Click New Detector. The Create new Detector - Effective Point of Measurement dialog opens:

Important Notice: Depth Correction
Due to the geometry of chambers, enter the depth correction with negative value for a cylindrical chamber and a positive value for parallel plate chamber, diode or diamond detector.

Option 1: Depth correction

Depth correction is selected if a depth deviation in measurements due to the geometric characteristics of a detector should be corrected. The correction is based on the value of effective point of measurement, Peff:
- Select Depth correction.
- Select one or more beam types to which the correction will be applied. The default depth correction for the beam type and the class of this chamber are automatically displayed. They can be edited by entering a new value in the corresponding box.
- Enter a negative value for a cylindrical chamber and a positive value for a parallel plate chamber, diode or diamond detector.
For cylindrical chambers and electron and photon beams, the default values are calculated as:
- Electrons: Depth correction = -0.5*r (electrons),
- Photons: Depth correction = -0.6*r (photons),
where r is the radius of the cylindrical chamber.

By clicking the Default button, the value will be reset to the default value.

By placing the mouse on the Info button , the formula for calculating the correction value will be displayed. For other type of detectors and electron and photon beams, no formula available in the software.

For all detector types with protons, and diodes/diamond detectors with photons/electrons, the default value is set to 0. No formula in provided in the software.

Option 2: No correction

If no correction should be applied, select No correction.

Click Create Detector. The detector will be added to the Installed Detectors list. The information of depth correction due to Effective Point of Measurement will be displayed in the Effective Point of Measurement group on the right-side.
Edit the name of the detectors or delete detectors in the Installed Detectors list using the Edit and Delete buttons.
If needed, select a reference detector from the list in the Reference Detector field.

Voltages group (2)

The Voltage section provides a predefined Default Bias Voltage and a Maximum Bias Voltage according to the selection in the Installation. However, it can be edited any time. However, when performing controller setup, the default value will be taken automatically for the selected detector.

Calibration group (3)

Enter the calibration parameters of the detector from the calibration protocol or certificate. This entry is mandatory for absolute measurements but not for relative measurements.

Effective Point of Measurement group (4)

For editing the parameters here, see description of the Create new Detector - Effective Point of Measurement dialog under the section of Installation (1) above for instructions.

Geometry group (5)

Figure 1. Equipment Setup – Detectors – Geometry

The Geometry group is a supplement to the Depth correction defined under Effective Point of Measurement (see description above). The parameters in the Geometry group are automaticallyset to the default values if the detector is selected in the Templates and is used at gantry 0°. They need to be edited when the detector (including those in or not in the Templates) is used for measurements at gantry 90° or 270°.

Radius: Detector inner radius

Water Correction Depth: WET (Water Equivalent Thickness) of the wall thickness (1) plus the water distance between the inner wall and the detector top (2)
