What about those from cultures and countries where reading is from
right to left? I believe right hand dominance is as prevalent as here
in the West. I am just musing.
We train left to right eye movements at a very early stage of a
child's development, before we teach them to read, whether they are
right or left-handed.

I thought chest films were turned on their side to ease detection
FWIW of rib fractures...
Seriously, I think the eye/brain interface seeks and detects
horizontal lines more easily. I don't know whether this is someting
to do with needing to find a horizon so we can keep our bodies the
right way up. This makes instinctive sense to me.
I examine lateral skull films brow up, HBL knee films patella up,
hands fingers up and almost all others in an 'anatomical' position
(head above neck etc)
Being a bear of little brain, I can't really cope with upside-down pictures.
