15.True regarding rotating anode
a.make
tube capable of withastanding high generated heat
b.theoretically
rotate at 3000 rpm
c.beveled
edge in tungsten disc
d.spread
the heat produced during an exposure
e.the
diameter of the tungsten disc affects
the maximum permissible loading of the anode
15.abcde---- Rotating anode
in x ray tube make tube capable of withastanding high generated heat by
spreading the heat produced during an
exposure,the diameter of the tungsten disc
affects the maximum permissible loading of the anode.Rotating anode has
beveled edge and it theoretically rotate at 3000 rpm.[Chapter 2,Page 15,
Christensen’s Physics of Diagnostic radiology]
