Equine TruDR

Variables
Many variables influence the X-ray
machine settings in a technique chart.
These include:
1. X-ray machine model
• This technique chart is for the
MinXRay ® HF100+ which has a max of
100 kVp and a variable mA generator.
When the kVp is set between 62 and
80 kVp, the mA is set to 25. When the
kVp is set between 82 and 100, the
mA is set to 20. To change the mAS,
one adjusts the exposure time
(seconds).
2. Distance from the X-ray machine to
the plate:
• This technique chart only applies with
an X-ray machine-to-plate distance of
24”.
3. Size of the patient
• < 6 months old
• 6-12 months old
• Average adult (1000 lbs)
• Large adult
4. Body part
• *All views of the distal extremities
(including pastern, fetlock, MC/MT,
carpus and tarsus) are taken using the
same settings.

Adjusting the technique chart
This technique chart is intended to provide a
guideline and may need to be adjusted in
order to produce an optimal image according
to your individual conditions and
preferences.
Steps involved:
Take an image and evaluate it.
• Too dark? Decrease mAS by half
• Too bright? Increase mAS by 2
• Too much contrast? Increase kVp
• Too little contrast? Decrease kVp
• Too noisy? Increase kVp
