FILTERING DEVICE FOR ULTRASONIC SIGNAL FILTRATION Russian patent published in 2016 - IPC A61B8/08 A61B8/12 A61B18/14 

FIELD: medicine.

SUBSTANCE: series of inventions refers to medical equipment, namely to devices for ultrasonic signal filtration in the ablation procedure. Ultrasonic signal filtering device, in which an ultrasonic signal is subjected to electric module comprises a first part (A), containing information on the object, from which ultrasonic signal was received, and the second part (B), which does not contain information on the object, comprises a module for determining the correcting signal indicating the effect of electric module on the ultrasonic signal from the second part (B) of ultrasonic signal and correcting module configured to correct the first part (A) of ultrasonic signal based on the determined correction signal to filter the effect of electric module from ultrasound signal. Ultrasonic reading device comprises a catheter including an ultrasonic module for ultrasound signal generation depending on ultrasonic waves, received from the object, additional module, which is electric one made with possibility of performing simultaneous operations and filtering device. Method of ultrasound signal filtering consists in using filtering device and machine-readable data carrier storing computer program for filtration of ultrasound signal. Method for ultrasonic reading of the object is provided by machine-readable data carrier storing a computer program for ultrasonic reading of the object and comprises steps of ultrasonic signal generation by ultrasonic module, wherein ultrasonic and additional modules incorporated into the catheter and operate simultaneously.

EFFECT: inventions series usage allows to reduce the effect of radio-frequency module.
