A phantom for the computer analysis of ultrasonic image quality comprises a housing, into which the test-zones, imitating an object of examinations, are located. These test-zones are made of material tissue-equivalent to biological environment with the inclusions of imitators as the test objects of diagnostic research zones. A sound-conductor as a silicon segment is attached to the upper part of housing and the imitators of test objects diagnostic research zones, which are located on different distances from each other, are placed. The areas of symmetric figures with the different echogenicity are made of material, selected from epoxide resin, foam-rubber quasi-chaotic texture, saturated with physiological solution, structured quasi-linear texture, made as the symmetric located empty openings, speckle- texture, made of polymer. |
