Ultrasonic diagnosis apparatus

摘要: There is provided an ultrasonic diagnosis apparatus capable of reducing unnecessary signal component in a reception signal. A plurality sign bits arranged the channel direction are extracted from element signals. binarization circuit applies processing to thereby generate data array. An evaluation value computing unit computes (GSCF) based on DC vicinity contained array frequency axis. This used adjust gain multiplier. With application processing, excessive reduction can be prevented. Further, as referenced, side-lobe appropriately reduced even if certain degree fluctuation exists main-lobe component.
