According to one embodiment, an ultrasonic diagnosis apparatus includes processing circuitry. The processing circuitry generates three-dimensional data based on an echo reflection intensity acquired through a probe, acquires a plurality of parameters including base color parameters, and the three-dimensional data, and generates a rendering image of the three-dimensional data using a value of color attenuation taking account of propagation of light based on the echo reflection intensity and using the base color parameters.

According to one embodiment, a position detection unit detects position information of an ultrasonic probe including ultrasonic transducers, with reference to a reference position. A transmission/reception unit supplies a driving signal to each transducer and generates a reception signal based on a reception echo signal generated by the transducer. Based on the reception signal, a three-dimensional data generation unit generates first three-dimensional data, in which a region corresponding to a living body tissue is specified by a specifying unit. A setting unit sets a first viewpoint based on the position information and specified region. An image generation unit generates a rendering image by rendering processing using the first viewpoint and first three-dimensional data.

According to one embodiment, an ultrasonic diagnostic device includes a first rendering unit, a second rendering unit, a superimposition processing unit, a display control unit. The first rendering unit generates a first rendering image according to a first rendering method based on volume data collected by three-dimensionally scanning a subject with ultrasonic waves. The second rendering unit generates a second rendering image according to a second rendering method that is different from the first rendering method, based on the volume data. The superimposition processing unit generates a superimposed image in which at least a part of the first rendering image and a part of the second rendering image are superimposed on each other. The display control unit causes a display device to display the superimposed image. The superimposition processing unit adjusts a superimposition ratio of the first and second rendering images in the superimposed image.

An ultrasonic diagnostic apparatus according to an embodiment includes a rendering controller, a detector, and a voxel data generator. The rendering controller divides three-dimensional data constituted by voxel data into a plurality of slice regions, rearranges the slice regions based on a sight line direction in which the voxel data is observed, and performs volume rendering on the voxel data in which the slice regions have been rearranged so as to generate image data. The detector detects image quality information indicating image quality of image data that is generated by the rendering controller. The voxel data generator rearranges the voxel data constituting the three-dimensional data based on the image quality information detected by the detector based on the sight line direction.

A medical image diagnostic apparatus according to an embodiment includes a setting unit, a rendering unit, and a display controller. The setting unit sets a viewpoint position and a calculation terminal position different from the viewpoint position on an image of a subject. The rendering unit performs rendering processing on, as a target, a range ahead of the calculation terminal position in a direction toward the calculation terminal position from the viewpoint position based on volume data of the subject so as to generate a rendering image.

In an ultrasonic diagnostic apparatus according to an embodiment, a direction determining unit determines a moving direction of an ultrasonic probe. A scanning control unit controls a transmitting and receiving unit so as to repeatedly perform first scanning for acquiring first image data by transmitting and receiving an ultrasonic signal in a first direction and second scanning for acquiring second image data by transmitting and receiving the ultrasonic signal in a second direction inclined toward the moving direction with respect to the first direction. An image superimposing unit generates panoramic image data by superimposing a plurality of pieces of first image data acquired through the first scanning. A display control unit displays the second image data together with the panoramic image data or the first image data on a display unit during scanning.

Ultrasonic diagnostic apparatus

An ultrasound diagnosis system, a medical image display apparatus and displaying method that simultaneously acquires virtual endoscopy image data and multi-planar-reconstruction (MPR) image data of a diagnosing target region based on the volume data acquired from an object. Virtual endoscopy image data is generated by setting up a viewing point and a viewing direction on a volume data acquired from the object. A marker is provided on a target region of a lumen organ shown in the virtual endoscopy image data for setting up an observing direction. A reference line started from the volume data is set up along an observing direction. By comparing a voxel value of the volume data that is crossing to the reference line with a prescribed threshold value, a reference point where a surface of the diagnosing target region crosses the reference line is set up to the volume data. MPR image data is generated by extracting each voxel of the volume data corresponded to each of three MPR cross-sectional planes that are mutually orthogonally crossing at the reference point and displayed with the virtual endoscopy image data.
