PURPOSE:To improve the connection of an image at every scan for an ultrasonic beam and to make a flow of blood easy to observe by inputting blood flow information from a color blood flow information detecting means, discriminating the input time of the blood flow information, fetching the blood flow information with different time phases from a blood flow information storage means, and outputting them after taking correlation. CONSTITUTION:A scan correlation circuit 12 for color blood flow is the one which inputs color blood flow information outputted from a color Doppler blood flow detecting part 6, and also, discriminates the input time of the blood flow information, and outputs the blood flow information with different time phases, for example, the one of one preceding time phase by fetching from the blood flow storage part 7, and a correlation part 12a for speed data, a correlation part 12b for velocity dispersion data, and a correlation part 12c for reflection intensity data which take correlation conforming to data of blood flow speed, velocity dispersion, and reflection intensity, are provided in the inside of the circuit. The correlation parts 12a-12c for each data are connected to memories 7a-7c corresponding to each data provided at the blood flow storage part 7, respectively, and also, old data of one preceding time phase read out from the memories 7a-7c can be fetched. |
