EXCITATION CIRCUITS FOR NON-EXPENSIVE TRANSDUCER ARRAYS Russian patent published in 2018 - IPC A61B8/00 A61B8/06 G01S7/52 

FIELD: medicine.

SUBSTANCE: group of inventions includes a device, a permanent machine-readable medium, and a method for ultrasonic imaging device operation. The device contains an array of transducer elements distributed to a plurality of groups for group work, and a processor configured to control the operation of the transducer elements array. The transducer elements array is controlled by the processor for visualization. The said array is used in parallel and in time with the use of transducer elements of the current one of the said groups of the plurality of transducer elements. Visualization is performed element-by-element independently. The groups of plurality of transducer elements are arranged in pairs in space with respect to each other to be element-wise connected to each other. Each group of plurality transducer elements only contains nonadjacent transducer elements, grouped according to the status of spatial location for all pairs of transducer elements of the first group, one or more transducer elements from one or more other groups are located between two transducer elements of a pair of transducer elements. Each transducer elements from the transducer elements array has a surface with a geometric center. The transducer elements from the transducer elements array are arranged so that the line passing through the geometric centers of at least some of the transducer elements of one group does not completely surround the transducer elements of any other group.

EFFECT: group of inventions allows automated, simple, low-interference ultrasonic visualization through non-phased visualization and independently, as well as through distribution of transducer elements by groups of multiple discontinuous transducer elements, and due to the fact that the line passing through the geometric centers of some transducer elements of one group does not completely surround the transducer elements of any other group.
