METHOD OF CONTROLLING THE INTRODUCTION OF SURGICAL INSTRUMENT THROUGH THREE-DIMENSIONAL ULTRASOUND VISUALIZATION Russian patent published in 2017 - IPC A61B8/08 

FIELD: medicine.

SUBSTANCE: sensor with a two-dimensional matrix transducer is placed on the acoustic window, ultrasonic signals are transmitted and ultrasonic echoes are generated by a sensor for ultrasonic imaging of the site of the invasive procedure in the body volume region. A plurality of two-dimensional images of each of the planes extending from the two-dimensional matrix of the transducers in the depth direction to at least the location of the invasive procedure are generated and simultaneously displayed in real time. The images spatially coincide in the thickness direction and are displayed in a spatially adjacent order, including at least one image of the site of the invasive procedure. Real-time two-dimensional images are updated as the invasive instrument is injected into the volume region along the insertion path directed to the site of the invasive procedure to observe the insertion of the tool as the tool approaches the site of the invasive procedure and sequentially crosses a plurality of spatially coincident two-dimensional images in real time. At the same time, at least two two-dimensional images in real time of spatially coincident image planes are displayed simultaneously. Each of the at least two two-dimensional images in real time contains the same portion of the invasive tool when the insertion path is not aligned with one plane of the image.

EFFECT: obtaining a high-quality image, eliminates the problem of the need to align the image plane and the needle.
