METHOD OF OBTAINING X-RAY IMAGE OF FISH Russian patent published in 2012 - IPC G01N23/83 

FIELD: physics.

SUBSTANCE: fish is placed between an X-ray source and an X-ray image receiver, wherein the distance X₁ between the X-ray source and the fish is equal to the length L of the fish or the analysed area on the fish and is three times shorter than the distance X₂ between the X-ray source and the X-ray image receiver, and the diameter of the focal spot d_fp is determined by a corresponding mathematical expression based on said parameters.

EFFECT: possibility of rapid obtaining of sharp images of fish which are magnified three times or more, including bones with diameter of 0,05 mm, which are vital for studying species and population anomalies of the structure of their skeletons.
