Abstract
In an ultrasound diagnostic apparatus of the present invention, the controller writes and reads element data of one frame into and out from two or more buffer memories 21a, 21b, . . . 21i sequentially frame by frame and assigns the element data of one frame sequentially read out from the buffer memories to a plurality of arithmetic blocks of a signal processor, wherein the element data assigned is subjected to processing by each of a plurality of arithmetic cores in the plurality of arithmetic blocks to produce an image signal.
Claims18
An ultrasound diagnostic apparatus comprising:
- a transducer array;
- a transmission circuit configured to transmit an energy beam toward a subject;
- a reception circuit configured to process a reception signal outputted from the transducer array that received ultrasonic waves generated from the subject upon transmission of the energy beam to thereby generate element data;
- two or more buffer memories into each of which element data of one frame is written;
- a signal processor constituted with a plurality of arithmetic blocks each including a plurality of arithmetic cores and configured to produce an image signal through processing of the element data of one frame read out from each of the buffer memories by the plurality of arithmetic cores in the plurality of arithmetic blocks;
- and
- a controller configured to write and read element data into and out from the two or more buffer memories sequentially frame by frame and to assign the element data of one frame read cut to the signal processor to the plurality of arithmetic blocks sequentially, to thereby cause the plurality of arithmetic cores to perform processing on the element data.
An ultrasound image producing method comprising the steps of:
- emitting an energy beam toward a subject;
- receiving by a transducer array ultrasonic waves generated from the subject upon transmission of the energy beam;
- generating element data by processing in a reception circuit a reception signal outputted from the transducer array that has received the ultrasonic waves;
- writing element data of one frame into each of two or more buffer memories in such a manner that the two or more buffer memories correspond to frames one by one;
- producing an image signal by assigning the element data of one frame sequentially read out from the buffer memories to a plurality of arithmetic blocks, and causing each of a plurality of arithmetic cores included in the plurality of arithmetic blocks to perform processing on the element data of one frame assigned;
- and
- repeating writing and reading element data into and out from the two or more buffer memories frame by frame.
