  • Patent number: 9468420
    Abstract: A medical imaging data processing apparatus comprising a data receiving unit for receiving imaging data, a rendering unit for rendering images from the imaging data according to one or more rendering parameters and a selection unit configured to output a plurality of images rendered by the rendering unit. At least one of the plurality of output images is rendered using one or more rendering parameter having a value that is different to the value used to render one or more of the other rendered images. The output images are selectable to select the value of one or more rendering parameters associated with the selected image.

  • Patent number: 9330485
    Abstract: Certain embodiments provide a photo-realistic rendering apparatus and method. An illumination model is used that includes placing a synthetic or virtual light source adjacent a region of tissue of interest in order to visualize the thickness of the tissue by modeling how light from the virtual light source interacts with the tissue of interest, through effects including absorption and scattering, as light emitted from the light source travels through the tissue of interest to a view point of view plane. It is simulated how some light is absorbed making tissue regions that are thicker darker (since more of the light is absorbed and the intensity reduces) and more red (since tissue tends to absorb blue and green wavelengths more strongly than red wavelengths and this chromatic effect is incorporated in the illumination model). A 2D image can thus be provided in which the color and intensity of light propagating through the tissue provides visual feedback on the tissue thickness.

  • Publication number: 20150164475
    Abstract: 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.
