Medical Imaging Practice Questions with 100%
Correct Answers
bone
X-rays mostly pass through skin and soft tissue, but they can't easily pass through ___ so can
be used in diagnostic imaging.
X-rays
___ can also be used to examine organs and identify problems such as pneumonia.
Transparent
Air is ___ to x-rays, where x-rays get through you get a dark image
opaque
bones are quite ___ to x-rays and soft tissue is slightly ____.
fluoroscopy
shows organs functioning in real time with x-rays
contrast
the ___ of x-rays can be increased by using material/dye that is opaque to x-rays.
tungsten target
electrons are emitted from the heated filament towards the ___ ___ due to the very potential
difference between them.
wasted as heat, undergo transitions, deflected and slowed down
when electrons jump across they do 1 of 3 things:
most of them get ___ ___ ___
, some ___ ____
some are ___ ___ ___ ___
copper mounting
the tungsten target has a ____ ____ because it conducts heat and is cooled by circulating oil
through the mount. Spinning the tungsten target at high speed also helps to stop it
overheating.
characteristic x-rays
When electrons jump across to the tungsten target some undergo transitions and release
energy in the form of ___ ___.
continuous x-rays
produced when electrons are deflected and slowed down, shown as the continuous line on the
graph.
intensity
___ = number of x-rays
Current
___ = carrier
voltage
the higher the tube ___, the higher the maximum frequency so the higher the maximum x-ray
energy.
metal filter
