Patent ID: 7758507

Claim:
A blood-flow image display equipment, comprising: an object, and second the rough value of blood flow velocity information about the object to a transmitting controller that determines and controls the transmission of a sending wave sequence; an ultrasonic transducer that transmits and receives ultrasonic waves according to the sending wave sequence; an ultrasonic two-dimensional image construction unit that constructs ultrasonic two-dimensional images using received ultrasonic waves; a vector measurement unit that measures a motion velocity of the object using a motion vector obtained from the ultrasonic two-dimensional images; a blood flow signal receiving unit that receives signals related to blood flow, and sets a blood-flow measurement area; a signal construction unit that constructs a time-series blood flow image, and that based on the motion vector measured by the vector measurement unit collects and retains signals related to blood-flow from the blood flow measurement area; an autocorrelation calculation unit that performs autocorrelation processing on the signals related to blood flow that are retained for use in constructing a time-series blood flow image, and measures a blood flow velocity and a dispersion value of that blood flow measurement area; and a blood flow image display unit that constructs and displays the time-series blood flow image that is rendered in multiple colors according to the measured blood flow velocity and a blood flow direction; wherein the sending wave sequence includes a signal for creating the ultrasonic two-dimensional images, and a signal for creating the time-series blood flow image; and wherein the transmitting controller further changes the sending wave sequence depending on the measured motion velocity of the object and the measured blood flow velocity.
