1.2.4 Determine dose polynomial coefficients

1.2.4.1 Introduction

The calculation of the dose polynomial coefficients should be carried out with each filter (copper

0.1mm and 0.5mm) and with the large focal spot.

1.2.4.2 Acquisition for copper filtration 0.1 mm and 0.5mm

1- Place the external sensor of the dosimeter in the center of the
detector against the frontal carbon panel and 5 cm above the
platform in high position.

2- Make sure the sensor is parallel to the carbon panel (see
photo below).

3- Using green lasers, set the high limit of the acquisition to 5cm
above the dosimeter and the low limit to 5cm below.
4- Start the OCEAN software and connect it to the dosimeter.
(Select "external detector" and New quick check)

5- Click on the Excel button as shown below

6- Then click on "Connect to workbook"
