AI Technical Summary

Problems solved by technology

[0004] However, ultrasonic images (B-mode images) tend to blur the outline of structures compared to other medical images such as X-ray CT images and MRI images.
Therefore, if the thickness of the lumen is not greater than a certain level, it is difficult to detect the lumen area of ​​the lumen from the B-mode volume data by automatic processing using a program.
Therefore, the virtual endoscopic display in current ultrasonic diagnostic equipment is limited to tubular tissues with a certain thickness, and it is difficult to apply to thin tubular tissues.

no. 1 Embodiment approach

[0022] First, the configuration of the ultrasonic diagnostic apparatus according to the first embodiment will be described. figure 1 It is a block diagram showing a configuration example of the ultrasonic diagnostic apparatus according to the first embodiment. Such as figure 1 As illustrated, the ultrasonic diagnostic apparatus according to the first embodiment includes an ultrasonic probe 1 , a display 2 , an input device 3 , a position sensor 4 , a transmitter 5 , and an apparatus main body 10 . In addition, the device main body 10 is connected to the external device 6 via the network 100 .

[0023] The ultrasonic probe 1 has a plurality of transducers, and these plural transducers generate ultrasonic waves in accordance with drive signals supplied from a transmission / reception unit 11 included in an apparatus main body 10 described later. The vibrator included in the ultrasonic probe 1 is, for example, a piezoelectric vibrator. The ultrasonic probe 1 receives a reflected...

no. 2 Embodiment approach

[0084] The first embodiment has been described above, but it can be implemented in various forms other than the above-mentioned first embodiment.

[0085] (1) Display methods other than virtual endoscope display

[0086] In the above-mentioned first embodiment, the method of obtaining the region of the ultrasonic volume data corresponding to the lumen region of the other type of medical image volume data based on the result of alignment between the ultrasonic volume data and other types of medical image volume data has been described. location, and conduct a virtual endoscope-based display of the situation. However, the embodiment is not limited thereto. For example, the ultrasonic diagnostic apparatus can also generate display image data in other display formats described below.

[0087] Figure 9 And 10 is a diagram showing another example of display image data. exist Figure 9 In , the case where the liver of the subject P is observed based on the two-dimensional ultras...

Abstract

An ultrasonic diagnostic apparatus according to an embodiment includes a positioning unit, a detection unit, and a generation unit. The alignment unit performs alignment between the three-dimensional ultrasound volume data and other types of three-dimensional medical image volume data different from the three-dimensional ultrasound volume data. The detection unit determines the position of the lumen region in other types of medical image volume data, and detects the determined position of the lumen region in the ultrasound volume data. The generation unit generates projection image data obtained by projecting the ultrasound volume data from a viewpoint set inside the lumen region based on the position of the lumen region detected by the detection unit, as display image data displayed on a predetermined display unit. .

Description

technical field [0001] Embodiments of the present invention relate to an ultrasonic diagnostic apparatus, a medical image processing apparatus, and an image processing method. Background technique [0002] Compared with other medical imaging diagnostic equipment such as X-ray CT (Computed Tomography) equipment or MRI (MRI: Magnetic Resonance Imaging) equipment, ultrasonic diagnostic equipment is superior in the ability to describe fine structures. A medical image diagnosis device useful for observing blood vessels. In addition, in recent years, ultrasonic diagnostic devices that generate time-series volume data substantially in real time using an ultrasonic probe capable of performing ultrasonic three-dimensional scanning have been put into practical use. [0003] Therefore, in the field of ultrasonography, a virtual endoscope display of volume data acquired by an X-ray CT (Computed Tomography) apparatus, a Magnetic Resonance Imaging (MRI: Magnetic Resonance Imaging) appara...
