Individual fluoroscopic and radiographic exposure limits govern allowable tech-
niques until the heat storage capacity of the anode is reached. Thereafter, contin-
ued operation can be maintained only at the limit of the anode dissipation rate of
75,000 heat units per minute until the tube unit capacity of 1,500,000 heat units is
reached. The input rate, including stator power, is then limited to 60,000 heat units
per minute for the radiographic casing and 75,000 heat units per minute for the
fluoroscopic casing.
Both the heat unit values shown for stator power and the heat unit values for
exposures must be considered in calculating the average input rates for extended
periods of operation.
The average energies attributable to stator power per exposure are as follows:
0–10,000 rpm
0–3,400 rpm
3400–10,000 rpm
Continuous operation
(fluoroscopy, normal
minute speed)
The tube rating charts are based upon a target temperature equivalent to 25% of
storage (75% remaining). For heavy duty operation where this temperature is
exceeded, 80% of the rating must be used.
