It definitely appears easier to see lines when they are aligned
horizontally. I reckon it's to do with using both sides of your
brain....when you look at a horizontal line, the projected image crosses
the (vertical) midline of the retina. The line is then represented in both
halves of your brain. As you scan your eyes along the line, any 'glitch'
will suddenly register as it appears in the respective side of cortex.
Perhaps this is why we read text horizontally (although I accept that the
japanese/chinese write vertically - they do, however, use more complex
characters, so perhaps you don't have to scan along the text so fast.) Just
a thought.

If the x-ray is for a fracture, then so the fracture line is horizontal
(digits pointing hoizontal for suspected spiral fracture, LisFrancs etc;
vertical for epiphyseal injuries). If it's looking for angulation, then
with
the proximal part of the bone due vertical. Horizontal lines are easier to
see than vertical; angulation off vetical easier to see than off
horizontal.
Don't know why.
