ACOUSTIC WAVE PROCESSING DEVICE, SIGNAL PROCESSING METHOD FOR ACOUSTIC WAVE PROCESSING DEVICE, AND PROGRAM

摘要

The acoustic wave processing device includes a data processing unit which performs superimposition processing on first element data or first reception data generated by performing phasing addition on the first element data to generate processed data, an image generation unit which generates a B mode image based on the first element data and the processed data, a bloodstream image generation unit which generates a bloodstream image based on bloodstream information included in the first element data, a region setting unit which sets a bloodstream image region, a processing region setting unit which sets a region for processing in the data processing unit based on information relating to the bloodstream image region, and a display image generation unit which generates a synthesized image of the B mode image and the bloodstream image.

1. An acoustic wave processing device comprising:
a probe which has a plurality of elements arranged to transmit an acoustic beam, to receive an acoustic echo reflected from an inspection object, and to output an analog element signal according to the received acoustic echo; a transmission unit which uses two or more elements among the plurality of elements as transmission elements and makes the probe transmit the acoustic beam multiple times so as to form a predetermined transmission focal point; a reception unit which receives an acoustic echo corresponding to each transmission of the acoustic beam with two or more elements among the plurality of elements as reception elements, receives analog element signals output from the reception elements, and performs predetermined processing on the analog element signals; an A/D conversion unit which performs A/D conversion on the analog element signals processed by the reception unit to convert the analog element signals to first element data as a digital element signal; a data processing unit which selects two or more pieces of data from a plurality of pieces of first element data output from the A/D conversion unit or a plurality of pieces of first reception data generated by performing phasing addition processing on the first element data and performs superimposition processing on the selected two or more pieces of data to generate processed data; a B mode image generation unit which generates a B mode image based on at least one of the first element data or the processed data generated by the data processing unit; a bloodstream image generation unit which generates a bloodstream image based on bloodstream information included in the first element data; a region setting unit which sets a bloodstream image region where the bloodstream image generation unit generates the bloodstream image; a processing region setting unit which sets a processing region where the data processing unit performs processing based on information relating to the bloodstream image region set by the region setting unit; and a display image generation unit which generates a synthesized image of the B mode image and the bloodstream image based on the information relating to the bloodstream image region set by the region setting unit.
