METHOD AND APPARATUS FOR ULTRASONIC IMAGING OF OBJECTS IN HIGH-TEMPERATURE LIQUID MEDIA Russian patent published in 2019 - IPC G01N29/44 

FIELD: ultrasonic visualization of objects.

SUBSTANCE: use for ultrasonic visualization of objects located in liquid media. Summary of invention consists in the fact that first acoustic waveguide 16 and waveguide matrix 18 are partially placed in the analyzed aggressive medium 1 (all other elements are placed in nonaggressive medium 6). At that, the first output end 17 and the second inlet ends 2 should be located in aggressive medium 1, the first input end 15 and the second output ends 7 in non-aggressive medium 6, and interface of media 5 should be located between first input end 15 and first output end face 17 and between second input ends 2 and second output ends 7. First acoustic waveguide 16 and waveguide array 18 are oriented by first outlet end face 17 and second input ends 2 towards intended location of object, wherein first output end 17 and second input ends 2 are located as close as possible to expected location of object. Typically, first acoustic waveguide 16 and waveguide array 18 are arranged on one side of the intended location of the object. If this was not done in advance, then at the second output ends 7 there installed is the device for determination of displacements 8, at the first input end 15 radiator 14 is installed, and emitter 14, generator 13, switch 12, sync generator 11, device for determination of displacements 8, processing unit 9 and display unit 10.

EFFECT: possibility of simplifying the design.
