The reference image display method

Discloses an ultrasonic imaging reference image display method and ultrasonic diagnostic apparatus, wherein the capture ultrasound images (105, 106) by the ultrasound probe (104). Obtaining a reference image (111) by extracting from the scanning plane is obtained in advance by a diagnostic imaging apparatus (102) and stored in the volume data storage unit (107) in the volume image data and the ultrasound image corresponding to the tomographic image. Displaying the ultrasonic image and the reference image (111) on the same screen (114). In this case, the portion extracted view range corresponding to the ultrasound image and the reference image generated by a fan of the image display the ultrasound image having a reference image of the same region.
