Description of the Related Art An ultrasonic diagnostic apparatus contacts a body surface of a subject with a probe, emits a rectangular or fan-shaped ultrasonic beam toward the body from the probe, and emits it from an organ or the like. The reflected wave is measured to obtain a tomographic image. Then, in recent years, a plurality of tomographic images of a diagnostic region are collected by shaking the ultrasonic beam in a direction orthogonal to the rectangular or fan-shaped surface, and the voxel method or volume rendering method using these tomographic images. Attempts have been made to reconstruct and display a three-dimensional image by such a method. Alternatively, a three-dimensional image is reconstructed by the same method as above using a plurality of tomographic images obtained by translating the probe in the lateral direction on the body surface of the subject at a constant speed in the lateral direction. It is also being displayed. The three-dimensional image obtained by these three-dimensional image display methods showed the spatial structure of the diagnosis target at a certain measurement instant.

た。However, in the above-described conventional three-dimensional image display method, for example, when a blood flow image is measured by Doppler measurement and a three-dimensional image is reconstructed, the ultrasonic wave propagation speed and measurement are performed. Due to the time, it was difficult to measure the real time completely. Therefore, it is not possible to display the state of time-dependent changes and the correct movement of organs and the like. In particular, so-called gate image measurement using electrocardiographic synchronization, which indicates the pulsation of the heart, is performed at sites such as the neck where blood flow velocity changes significantly over time. The blood flow was unknown, and the measurement time was long. Further, in the conventional image display method, since the state of the temporal change is not displayed in the three-dimensional image as described above, when observing the heart or blood flow, abnormal movement of the heart or blood flow It was difficult to understand the abnormal flow and difficult to diagnose.

The body 1 of the subject 1 comes into contact with the body surface of the site where the organ 6 to be diagnosed (for example, heart or blood vessel) exists. next,
The ultrasonic beam B is projected while the probe 2 is fixed at this position, and the tomographic image data is measured by a normal method for a fixed time. At this time, the measurement time of the tomographic image differs depending on the diagnosis target and the measurement purpose, but since the frame rate of the image is 30 images / second in a normal ultrasonic diagnostic apparatus, it may be measured for several seconds. When it is desired to measure the time of arrhythmia in the heart, it is sufficient to measure images for a total of about 3 seconds before and after the time when the arrhythmia occurs. This allows
A plurality of tomographic images that are continuous in time series are acquired for one cross section of the organ 6 to be diagnosed.

It is possible to display a temporal change in one cross section of the diagnosis target in the subject as a three-dimensional image. As a result, a temporal change of an arbitrary cross section of the target organ in real time is three-dimensionally displayed as an image, and the momentary change of the organ is displayed as a shape that continuously changes in the time axis direction. Therefore, for example, when observing the heart or blood flow, abnormal movement of the heart or abnormal flow of blood flow can be well understood as a shape change of a three-dimensional image, and normal or abnormal diagnosis can be performed easily and accurately. You can Further, the probe to be used need not be a special one for displaying a three-dimensional image, and may be a normal probe as it is. Therefore, a three-dimensional image can be displayed easily and inexpensively.
