An ultrasonic diagnosis and treatment system includes an ultrasonic probe for transmitting and for receiving ultrasonic waves an image generator unit for generating an ultrasonic image based on the echo signals received by the ultrasonic probe a display unit for displaying an ultrasonic image generated by the image generator unit and a biopsy needle for radiating radiofrequency waves. The ultrasonic diagnosis and treatment system includes a display controller unit for displaying on the display unit an ultrasonic image at the time of non-radiation of the radiofrequency waves generated based on the echo signals received by the ultrasonic probe at the time when the radiofrequency waves are not radiated from the biopsy needle, in place of the ultrasonic image at the time of radiation of the radiofrequency waves generated based on the echo signals received by the biopsy needle at the time of radiating the radiofrequency wave from the biopsy needle.
