How do I activate the software after I bought the license?

To activate your license, you need to register it either automatically, if a workstation is connected to the Internet, or manually, if it is not.

Automatic:

Press “License” in the main window title bar and select “Registration/Activation”. In the window that opens, enter your serial number, choose automatic activation type, and enter your email address. Click “Activate” to complete the registration. Please note that automatic activation is possible only if your machine is connected to the Internet.

Manual:

Go to www.qubyx.com/index.php/register and fill out the form. Enter the serial number provided above, the generated workstation ID, and user information.

To get the generated workstation ID the form requires, open the “Registration/Activation” window in the software and select manual activation type. The software will provide a generated workstation ID.

When the filled out form is submitted, you will receive an activation code by email. Enter this code into the corresponding field in the “Registration/Activation” window of the software and click “Activate”.

How can I upgrade my PerfectLum3 to PerfectLum4?

You just need to download PerfectLum 4 and install it. All preferences and history from your previous versions will be preserved.

The upgrade is not free, but we offer special pricing on PerfectLum v4 for PerfectLum v3 users. Contact us at sales(at)qubyx(dot)com to receive a quote.

Is it possible to disable automatic updates of PerfectLum?

Yes, please go to PerfectLum preferences (Ctrl+P on Windows or Function+P on Mac) and uncheck “Update software automatically” in Application tab.

I need to calibrate the display to a high luminance level, e.g. 500 cd/m2. Can I do that with PerfectLum?
PerfectLum does not have any restrictions as to the highest possible luminance level. This depends on the capabilities of your display (maximum luminance is normally stated in display specifications). If your display is capable of reproducing 500 cd/m2, PerfectLum can calibrate it to this level.

Target luminance level can be defined in Preferences > Calibration Settings > Set White Level.

Can I compare “before” and “after” calibration to see the results?
In PerfectLum you can check the calibration effect visually, using test patterns. After you have successfully calibrated the display, go to Tools > Display Test Pattern in PerfectLum main window. There you can choose one of the test patterns or any other image from your PC. Click “View and Check” to view the test image, and in the top right-hand corner you will see a button to switch off and switch on the calibration. If you want check the effect not on the test image, but just in general, use the PerfectLum LUT Loader tray icon (bottom right-hand corner). Right-click on it and you will see the name of your display(s) with a tick (this means that calibration LUT is applied on a display). Left-click on the display name to unapply the calibration LUT and to apply it again.
I've lost my PerfectLum3 preferences password, how do I restore or reset it?

To reset your password, you need to close LUT loader and PerfectLum applications first. Then go to C:\programdata\qubyx\perfectlum and delete the full database file called storage.db.
*** Please note: all history data and settings will be lost.

I´m getting an error message “LUT upload failed” during the calibration process.
Verify if the graphic card you are using has a LUT (Look Up Table). If you are using a laptop with a 2nd display connected, you may not be able to calibrate the external display, as laptop graphic cards usually have only one LUT. In this case select the external display in single display mode (you can do that in your OS settings or video card settings).
I´m getting an error message “sensor not found”.
Verify if the sensor is connected correctly to the machine and if the USB port is active. Eventually change the port to test. Reboot the computer, and if you are still getting the error message, contact support(at)qubyx(dot)com for help on sensor installation.
I need to customize standard QA procedures to my needs. Can I do that in PerfectLum?
You can create a personalized QA procedure in PerfectLum 3.0 Suite in Regulations Manager.

To open Regulations Manager, go to PerfectLum Suite -> Preferences (or press Ctrl+P), select QA settings tab -> Regulation -> Regulation Manager.

When the regulation manager window pops up:

1. choose what default regulation (AAPM, DIN, JESRA) and classification (primary, secondary) will your regulation be based on. Pick the name for your regulation and click “Continue” button;

2. in the next pop up window (Regulation Editor) select steps that will be included in your regulation by checking/unchecking boxes. Then select frequency of constancy tests for each step. If you select “none” frequency, the step will not be included in constancy tests;

3. select if acceptance test will be mandatory for your regulation by checking/unchecking corresponding box. If the box is unchecked, constancy tests will be already scheduled in the scheduler tab, if you check it – you need to pass acceptance test first;

4. to edit thresholds for your regulation, press “Parameter Editor” button. In the pop up window double click on a value to edit it and press “enter” to save it;

5. press “Save” to save your regulation and close the regulation editor.

Back in the main window of regulation manager there are four more options:

– “Open User Regulation to Edit” – enabled once you have created/imported at least one regulation. Choose this option to edit one of your regulations;

– “Export User Regulation” – enabled once you have created/imported at least one regulation. Allows exporting your regulation to a separate file;

– “Import User Regulation(s)” – choose this option to import one or more user regulations;

– “Delete User Regulation” – enabled when at least one user regulation is available. Choose it to delete aone of the regulations you created or imported.

MORE

Can a standard display (non-medical grade display) be calibrated to suit DICOM GSDF curve as per the different ambient luminance value?

Yes, you can calibrate any display to DICOM GSDF with PerfectLum. PerfectLum does also take the ambient light into account.

If the monitor is not meeting the DICOM greyscale value, how does PerfectLum help to adjust the value?

The software will create a correction LUT and upload the LUT into the Display (if supported) or does apply on the graphics board.

Do we need any special type of monitor for this application?

No, you can use any display. 

Does PerfectLum generate LUT as per deviation during calibration (which the end-user must incorporate into their image viewing software)?

The correction LUT is applied on the graphics board or into the monitor. You can apply other specific LUT’s inside your application.

How does PerfectLum manage the impact of ambient light?

At the beginning of the calibration the software will measure the veiling glare. The veiling glare value will be used as an offset during the calibration.

Does PerfectLum support VeriLUM grey scale photometer which I have already?

Yes, see supported measuring devices in PerfectLum software manual

Is this software free or I have to buy?

Software is free to try for 30 days and after it can be purchased on line.
