Problems solved by technology

First of all, there is a problem that it takes a long time to perform scan conversion of 3D data in conventional 3D ultrasound diagnostic equipment
This may lead to an increase in the amount of calculation
As described above, the conventional 3D ultrasonic diagnostic apparatus has a problem in that it takes a long time to perform conversion processing of 3D data in order to obtain a desired type from 3D data
Second, since acquired data is not stored as 3D data in conventional ultrasonic diagnostic devices, there is a problem that 3D information of a target object should be acquired as long as the target object is diagnosed
[0005] Third, there is a problem that conventional 3D ultrasound devices do not provide images in 3D sections (eg, coronal, sagittal, or axial planes) that are adequate for diagnosis
That is, the conventional 3D ultrasonic diagnostic apparatus focuses on the 3-dimensional display of the target object without displaying the cross-section necessary for examining the patient

Embodiment Construction

I. Real-time multi-section images

[0009] Figure 3A is a diagram illustrating a real-time ultrasonic diagnostic system 300 according to a preferred embodiment of the present invention.

[0010] Such as Figure 3A As shown, the real-time ultrasonic diagnostic system 300 includes a probe 301 , a display device 303 and a main body 302 . The probe 301 is used to acquire 3D data of a target object to be displayed. A mechanical scanning process (scanning by moving a robotic arm or rotating a stepper motor) or a hands-free process (scanning by a user's hand) can be applied to the probe 301 . The display device 303 (for example, a monitor) is used to display the data acquired from the probe 301 . It should be noted here that any type of display device can be used as long as the display device can display the 3D image according to the present invention. The main body 302 processes 3D data acquired from the probe 301 to be displayed on the display area of ​​the display device 303 ...

Abstract

An apparatus for displaying sectional planes of a target object utilizing 3 dimensional (3D) ultrasound data. The apparatus is capable of scanning the target object in real time by improving a scan conversion speed and virtually scans the target object by storing previously acquired 3D data. The apparatus, which displays a target object by using 3D ultrasound data, includes 1) a scan conversion unit for performing scan conversion to convert Cartesian coordinates for display on a screen of a display device to conical coordinates of 3D data, and 2) a rendering unit for rendering multiple sectional plane images, based on the 3D scan conversion, parallel with a reference sectional plane.

Description

technical field [0001] The present invention relates to an apparatus and method for displaying a cross-section of a target object using 3-dimensional (3D) ultrasound data. More particularly, the present invention relates to an apparatus and method for displaying a cross-section of a target object using 3D ultrasound data for real-time display of the target object. Background technique [0002] Generally, in a system using 3-dimensional (3D) ultrasound data, a 3D ultrasound diagnostic apparatus acquires 3D ultrasound data of a target object by using a probe. Then, the 3D ultrasonic diagnostic device displays a 3D image of the target object on the screen of the display device by converting the conical coordinates of the acquired data into rectangular coordinates suitable for display (scan conversion). Through scan conversion and rendering, an image area of ​​a target object displayed on a screen of a display device is called a "view". Figure 1 illustrates an example of a vie...
