X-Ray Generator Technical Specifications
KODAK 9000 3D Extraoral Imaging System_User Guide (SM710)_Ed 01 7–5
X-Ray Generator Technical Specifications
The x-ray generator comprises the following:
•
A transformer and an x-ray tube and their associated electronic components immersed in oil
•
An aluminum filter, which enhances the quality of the beam and reduces the dose received by the patient
•
A lead collimator, which limits the size of the beam at the image receiver unit
•
A thermal cutout, which trips at an operating temperature between 63 to 70° C ( ± 5° C)
Measurement Conditions
kV Indirect on the peak kilovolt meter
mA Direct measurement in the circuit using an oscilloscope
Exposure time Measurement at 75% of the kV values with peak kilovolt meter
