Speckle Reduction Apparatus In Ultrasound Imaging

The present invention relates to a speckle reduction in ultrasound imaging device, comprising: an array and outputting a plurality of channel signals to form an ultrasound image frame, the reflection signals coming back from the body's internal organs to individually received at the transducer, each of the receiving elements trans transducer and, Spain and the receive-focusing unit for selectively signal processing as for a plurality of channel signals so large pattern is changed by using the channel selection window function, a plurality of channel selection by the number required to form an ultrasound image frames that appear in the ultrasound image frame and store the window function and a plurality of channel selection outputs to the sub-receive-focusing the channel selection window function comprising a plurality of weights for selecting any channel for a channel signal window function, the output unit, and optionally signal by the sub-receive-focusing by synthesizing a plurality of scan line signal processing unit for forming a video frame Subject to a number of units of image frames stored in the unit image storage unit to form a unit image combining unit, and a unit image storage unit for storing a plurality of unit video frame formed in the unit image combination unit, and the speckle is reduced ultrasound image in that it comprises a processing unit for the averaging process averaging image features. The present invention can be by using the channel selection window function on a single channel signal received by the array transducer to the signal by selectively processing the channel to reduce the speckle noise, improving image quality of the ultrasound image.
