SETT OCH ANORDNING FOR BESTEMNING AV EN KROPPS INRE UPPBYGGNAD MEDELST AKUSTISKA STRALAR

摘要

A method and device for determining the internal structure of a body by means of acoustic beams. Transit times and intensities of acoustic beams passing through the body in different spatial directions are measured to establish the refractive index distribution and the acoustic absorption coefficient distribution, respectively at the points of a point matrix associated with the body. The non-rectilinear course of the acoustic beams is taken into account in this respect. This results in reconstructed images of higher quality.
