Philips Azurion - 10.5.2 Select Series Task; 10.5.3 Calibration Task; Automatic Calibration

When the c
alibraon factor is accepted, the system progresses automacally to the Analysis task.
NOTE Auto calibraon is available if the appropriate image aributes in the selected series (source
image distance, source object distance, and image plane pixel spacing) did not change during
acquision. If you choose auto calibraon in this case, ensure that the region of interest is in
the isocenter.
10.5.2 Select Series Task
You use the Select Series task to select an image series for analysis.
NOTE Only XA exposure images can be used for analysis.
NOTE Series with image pixel sizes greater than 0.225 mm for QCA and greater than 0.4 mm for
QVA are subopmal for analysis.
NOTE You can decrease the detector eld size or decrease the frame speed to obtain smaller pixel
sizes.
1 Click Select Series in the task panel.
2 Select the desired image series in the Select Series dialog box and click Select to open the series.
10.5.3 Calibraon Task
To allow accurate measurement during analysis and to ensure that measurements are displayed in
relevant units, the image must be calibrated.
NOTE You can congure default sengs for calibraon using the Customizaon screen. For details,
see Changing Default Calibraon Sengs (page 183).
You can perform calibraon automacally or manually using the Calibraon task.
Condions
For accurate manual calibraon, follow these guidelines:
• Posion the calibraon object close to the posion of the anatomy under invesgaon.
• Choose a calibraon object of intermediate size (a few cenmeters) for opmal accuracy.
For manual catheter calibraon, follow these guidelines:
• Use a radiopaque catheter.
• Use a lled catheter to improve detecon.
• Use catheters for calibraon that are at least 6 French. Catheters below 4 French are not supported.
• Ensure that the external catheter size as provided by the manufacturer is accurate.
Ensure that the image quality is good and that the contrast between the calibrang object and the
background is good.
Automac Calibraon
2D-QA can calculate the calibraon factor automacally if the required informaon is available in the
image series.
1 Click the Calibraon task.
