no. 1 approach

[0041] Next, a first embodiment will be described with reference to the drawings.

[0042] figure 1 A block configuration diagram of the ultrasonic diagnostic apparatus of this embodiment is shown. As shown in the figure, this ultrasonic diagnostic apparatus includes: an ultrasonic probe 11, an ultrasonic transmitting and receiving unit 21, a B-mode processing unit 23, a Doppler processing unit 25, a volume data generating unit 27, a projected image generating unit 29, an interface unit 31, Input device 33, image synthesis unit 35, display unit 37, two-dimensional ROI setting unit 39, determination unit 41, calculation unit 43, three-dimensional ROI determination unit 45, control unit 47, internal storage device 49, color tone changing unit 51 . In addition, an unillustrated biological signal measuring unit represented by an electrocardiograph, a phonocardiograph, a pulse recorder, and a respiration sensor and a network may be connected to the ultrasonic diagnostic apparatus...

no. 2 approach

[0079] Next, a second embodiment will be described with reference to the drawings.

[0080] The difference from the first embodiment is that instead of the average contribution value, the sum of the voxel values ​​of the voxels included in the set three-dimensional area becomes the largest along the direction from the projection plane of the VR image. The 3D-ROI is determined according to the distance in the direction of the line of sight.

[0081] Figure 7 A block configuration diagram of the ultrasonic diagnostic apparatus of this embodiment is shown.

[0082] Next, among the components of the second embodiment and the first embodiment, components that perform different operations and the three-dimensional region setting unit 42 will be described. In addition, in the case of realizing the technical idea of ​​the ultrasonic diagnostic apparatus with a medical image processing apparatus, there are, for example, Figure 7 The structure within the dotted line.

no. 3 approach

[0094] Next, a third embodiment will be described with reference to the drawings.

[0095] The difference from the first embodiment and the second embodiment is that the voxel value of the voxel included in the shell of the three-dimensional area is included according to the sum of the voxel values ​​of the voxel included in the set three-dimensional area The distance along the line-of-sight direction from the projection surface of the VR image at which the difference of the sum becomes the largest determines the 3D-ROI.

[0096] The block diagram of the present embodiment and the block diagram as the second embodiment Figure 7 same. Next, among the components of the second embodiment and the first embodiment, components that perform different operations and the three-dimensional region setting unit 42 will be described. In addition, in the case of realizing the technical idea of ​​the ultrasonic diagnostic apparatus with a medical image processing apparatus, for example, t...

Abstract

The invention provides an ultrasonic diagnosis apparatus, a medical image processing apparatus, and a medical image diagnosis apparatus, which can simply and quickly determine the 3D-ROI without considering the three-dimensional images and a plurality of two-dimensional images one by one in mind. The specifying unit 41 specifies cells on rays which pass through the respective pixels in the 2D-ROIand are used to acquire a VR image. The calculation unit 43 calculates the contribution degree of each cell based on the voxel value and opacity of each cell specified and calculates the average value of the contribution degrees of cells equal in distance from the screen of the VR image along the line-of-sight direction. The three-dimensional region-of-interest determination unit 45 specifies thedistances from the screen of the VR image which correspond to average contribution values exceeding the predetermined threshold and determines the position of the 3D-ROI in the volume data.

Description

[0001] The present invention is based on the Japanese invention patent application with the application date of January 8, 2010 and the application number 2010-003301, claiming the priority of the prior patent application, and all technical contents of the prior patent application are included in this application inventing. technical field [0002] The invention relates to an ultrasonic diagnostic device, a medical image processing device and a medical image diagnostic device. Background technique [0003] In various image diagnostic apparatuses in recent years, not only a two-dimensional image of one cross section but also three-dimensional image data (hereinafter referred to as volume data) can be obtained. In order to analyze the obtained volume data, various display methods that are easy for the user to understand have been proposed. [0004] As a method of displaying volume data, for example, a method of displaying three arbitrary cross-sections (hereinafter, referred ...
