ULTRASONIC TOMOGRAPHIC SCANNER Russian patent published in 2014 - IPC A61B8/13 A61B8/08 

FIELD: medicine.

SUBSTANCE: invention refers to medical diagnostics, namely to ultrasonic non-linear tomographs. The tomographic scanner comprises a receiving emitter with a receiving-emitting electroacoustic transducer with a signal forming channel connected to an input thereof, and a signal analysis channel connected to an output thereof. The receiving emitter comprises emitting plane electroacoustic transducers with an emitted coded ultrasonic signal broadband, and a receiving plane electroacoustic transducer with a received signal broadband. The working surface of the transducers is arranged in a tangential plane to a circle which encloses a scanned organ, and orthogonal to the circle plane, while its diameter is 1.5÷2.0 times more than a width of the working surface of the plane transducers. An angle of acoustic axes perpendicular to the working surface of the plane electroacoustic transducers for each pair of the adjoining plane electroacoustic transducers is within the range of 30° to 90°.

EFFECT: using the device provides high resolution of recovery and visualisation of internal structures of soft tissues and internal defects of various objects with a low noise level.
