Different shades of black and white in an image

Shades of black and white in an image depend upon the tissue reflectivity of the ultrasound

beam

There is very little reflection from the fluid, hence the image will be black (anechoic), like

blood, urine or amniotic fluid

There is highest reflection from the bones, hence the image will be bright white (hyperechoic),

like a human skull, vertebra

There is variable reflection from the soft tissues, hence the image of the soft tissues will be in

different shades of grey, like human brain
