Patent ID: 7022079

Claim:
An ultrasonic diagnostic apparatus, comprising: an ultrasonic probe for transmitting ultrasound to a subject having been injected with a contrast agent, and receiving ultrasonic echo from the subject; a driving signal generator for generating a driving signal for driving the ultrasonic probe; a control unit for controlling the driving signal generator based on a predetermined scan sequence for plotting a time-varying concentration graph of the contrast agent; a signal processor for applying a detection process and a logarithmic transformation process to the ultrasonic echo; an image generator for generating an ultrasonic image based on an output of the signal processor; an antilogarithmic transformation unit for applying an antilogarithmic transformation process to an output signal coming from at least either of the signal processor or the image generator; and a processor for plotting a time-varying graph based on the output signal coming from the antilogarithmic transformation unit.
