Abstract: An image processing module includes an input unit, a weight operator, and a synthesizer. The input unit is configured to receive a plurality of input signals of a plurality of channels. The weight operator is configured to calculate at least one weight to be applied to each channel based on at least one converted signal. The at least one converted signal is acquired by converting at least one input signal among the plurality of input signals of each channel, or by converting a synthesized input signal of the plurality of input signals of each channel. The synthesizer is configured to synthesize the plurality of input signals of the plurality of channels using the weight.

Abstract: An ultrasonic probe includes a multi-dimensionally arrayed transducer, a matching layer, and a backing layer. The transducer includes element groups having different focal distances and simultaneously transmitting ultrasonic signals toward an object. According to the ultrasonic imaging apparatus using the multi-dimensionally arrayed transducer, a multi-focus transmission is performed. Thus, the multi-focus ultrasonic image may be acquired within a short period of time, thereby increasing frame rates, and a high-quality image in which all areas are focused may be quickly acquired.
