Generating the Goal Image
You use the Generate Goal procedure to generate the goal table for the selected
target/filter combination.The goal table will be created for the mAs value used by
the Generator to create the goal images.
Before performing the Generate Goal procedure, you must have a valid mAs value.
If you do not know a valid mAs value, you can perform the HVL and ESE
procedures to determine it. Refer to “Determining the Half Value Layer (HVL)” on
page 4-5 and “Determining the Entrance Skin Exposure (ESE)” on page 4-8.
During the procedure, you will choose the number of goal images (1 to 4) to average
together for the final result. The tool instructions will prompt you to enable capture
and expose for each of the images. When the final image exposure is complete, the
tool will automatically generate the goal table with a name derived from the
target/filter combination used. The goal table will then automatically be loaded to
the DirectRay PXCM.
To generate the goal image:
1. In the tool’s main window, select the Generate Goal procedure option
NOTE: You can select the Generate Goal option without performing the Determine HVL and
Determine ESE procedures, provided you know the proper mAs to configure the Generator.
In the main window, the settings change and instructional text is displayed.
