A display device configured to display an endoscopic image obtained by an endoscope for observing an object is provided. The display device includes a projecting unit configured to project coordinate axes set to the object onto the endoscopic image, and a display unit configured to display thereon the endoscopic image and the coordinate axes projected onto the endoscopic image.

Display device, medical device, display method and program

An image processing method includes identifying a body region in a tomographic image based on pixel values within the tomographic image, extracting a bone muscle region corresponding to essential parts of bones and muscles based on bone muscle pixels having pixel values corresponding to the bones or muscles in the body region, searching boundary points of the bone muscle region from outside a region surrounding the extracted bone muscle region to inside the region, creating a bone-muscle region outer peripheral profile line by joining only boundary points at which each index related to at least one of a length and a slope of a line segment connecting between the adjoining boundary points of the searched boundary points satisfies a predetermined condition, and extracting a visceral fat region comprised of fat pixels having pixel values corresponding to fat in a region lying inside the bone-muscle region outer peripheral profile line.

Image processing method and image processing apparatus, and program

To allow the correspondence between a region having different susceptibility and a tissue structure to be easily visible, a phase change weighted image is produced by use of a phase of each pixel of phase change image data and a color bar, and an absolute value image is produced by use of an absolute value of each pixel of absolute value image data and a grayscale. Then, a phase change fused image in which the phase change weighted image and absolute value image are overlaid on each other is displayed.

Method and apparatus for displaying phase change fused image

In order to visualize a narrow blood vessel overlapping a thick blood vessel, at the time of performing a maximum intensity projection on three-dimensional image data, three-dimensional image data is weighted with a plurality of weighting functions of different attenuation characteristics along a projection line. Maximum intensity projections are performed on the plurality of pieces of the weighted three-dimensional image data, and results of all of the maximum intensity projections are summed. The weight of the weighting function is zero until the projection line reaches the surface of an image and, after the reach, gradually decreases from an initial value. Alternatively, the weight of the weighting function is zero to some midpoint of the projection line and, after the midpoint, gradually decreases from the initial value. The midpoint is adjustable. The attenuation characteristic is given by an exponential function. Parameters of the exponential function are adjustable.
