[0039] figure 1 is a block diagram of a basic ultrasonic imaging system to which an ultrasonic diagnostic apparatus of one embodiment of the present invention is applied. As shown in the figure, the diagnostic imaging system includes an ultrasonic diagnostic apparatus 101 according to an embodiment of the present invention and a medical diagnostic imaging apparatus 102 for obtaining volumetric image data as a reference image. Volume image data refers to data of a multi-slice image obtained by capturing the inside of a patient's body along a plurality of planes. Data of volume images captured by the medical diagnostic imaging device 102 are input to the ultrasonic diagnostic device 101 . A computed tomography device (X-ray CT device) or a magnetic resonance imaging device (MRI device) may be used as the medical diagnostic imaging device 102 . It is well known that CT images and MR images have better image quality than ultrasound images and are therefore suitable as reference ...

Abstract

Ultrasonograms (105, 106) are created by means of ultrasonic probe (104). Volume image data is created previously by using an image diagnosis apparatus (102) and stored in a volume data storage unit (107). From the stored volume image data, a tomogram corresponding to the scan surface of the ultrasonic images is extracted, and a reference image (111) is formed from the tomogram. The ultrasonograms and the reference image are displayed on the same screen (114). An area of the reference image corresponding to the viewing area of the ultrasonogram is extracted, and a reference image of the same portion as that of the ultrasonic image is displayed as a fan image and / or displayed with the same magnification as that of the ultrasonograms.

Description

technical field [0001] The present invention relates to a reference image display method for ultrasonic imaging and ultrasonic diagnostic equipment using the method. More specifically, the present invention relates to a technique preferably for real-time reconstruction using multislice image data of a patient obtained by diagnostic imaging equipment, a reference image of the same cross-section as the ultrasound scan plane, and for real-time reconstruction at the same The reference image and the ultrasound image are displayed on the screen. Examples of such diagnostic imaging equipment include ultrasonic diagnostic equipment, magnetic resonance imaging (MRI) equipment, and X-ray computed tomography (X-ray CT) equipment. Background technique [0002] Ultrasonic diagnostic equipment as a diagnostic imaging device is commonly used for diagnosis because they are easy to operate and can perform noninvasive observation of arbitrary cross-sections in real time. On the other hand, ...
