PURPOSE:To enable the altering of a color flow mapping (CFM) processing such as an MTI filtering for a freeze image or the like by including a means between a phase detection means for outputting a bipolar video signal and a CFM processing means to store the bipolar video signal. CONSTITUTION:When an operator performs a freezing operation of a diagnosis image, a bipolar video signal outputted from a phase detection section 6 is inputted into two A/D converters 7. Data converted into digital from analog are stored into a memory 14. Then, the data is read out of the memory 14 according to an operation such as an MTI filtering processing of the operator and undergoes a CFM processing at a CFM processing section 8 starting from an MTI filter. The data processed is inputted into a DSC4. The DSC4 processes the data inputted to output 8 mode image information, speed information, variance information, power information or the like to a display device 15 as RGB signal. Thus, as the bipolar video signal is stored before the CFM processing section 8, the data stored can be read out repeatedly to continue the CFM processing such as MTI filtering. |
