What is Photo-Acoustic Tomography?

it is photography of a party under surface

a laser light falls onto the tissue and the molecules eat the light

and BOOM ! -THERMAL EXPANSION-

then the pressure gets higher!!

and iconic acoustic waves are born

These photo-acoustic waves are captured by sensors

and a lovely algorithm makes an image of it

so we see what's going on under the tissue

such as skin cancer, which is not a nice party

see the lovely algorithm ⊂(✰-✰)つ > > >
