Table 5-1
Maximum kVp and mAs Ratings
It is important to note that the kVp setting takes precedence over your mAs setting. That is, if your
technique would generate too much heat for the x-ray tube anode, the mAs setting will
automatically decrease to permit the selected kVp.
– For instance, if kVp is set at 110 then your maximum mAs will not exceed 200.
NOTE:
The maximum allowable kVp and mAs ratings stated within this operation manual and as allowed
by the equipment, may appear to exceed the tube ratings. The reason for this apparent
discrepancy is that the tube rating charts in Product Data Sheet 2236721-100 are based upon a
25% heated tube assembly (75% heat units remaining), while the actual maximum allowable kVp
and mAs ratings are based upon a cold tube assembly. The Definium AMX 700 generator contains
a proprietary heat loading algorithm which protects the tube assembly for all heat loading
conditions.
