    摘要: A CT value of an image within a region of interest is calculated with time. While the calculated CT value does not exceed a predetermined threshold value, a reconstruction mode used when an image is reconstructed from projection data is set to half reconstruction. On the other hand, while the calculated CT value exceeds a predetermined threshold value, the reconstruction mode is set to segment reconstruction.

    摘要: An image processing apparatus includes a contrast side obtaining unit, estimating unit, a simple side obtaining unit, a core area computing unit, a synthesizing unit and a display control unit. The contrast side obtaining unit obtains a contrast area and a high CT value area around the contrast area. The estimating unit estimates a contrast area in the non-contrast data and corresponding to the obtained contrast area. The simple side obtaining unit obtains a high CT value area around the estimated contrast area. The core area computing unit computes a core area included in the high CT value area of the contrast data and the non-contrast data. The synthesizing unit aligns the contrast data with the non-contrast data and generates superimposed data by superimposing the high CT value area of the contrast data on the non-contrast data. The display control unit displays the superimposed data on a display device.

    摘要: A medical image processing apparatus to accurately identify malignant transformations of probable tumors. The medical image processing apparatus including a specifying mechanism and first, second, and third computing mechanisms. The specifying mechanism specifies a probable tumor from medical image data upon receiving the medical image data obtained by imaging a subject by a single medical imaging apparatus. The first computing mechanism calculates morphological information indicating morphological characteristics of a specified probable disease based on this medical image data. The second computing mechanism calculates functional information of the specified probable disease based on this medical image data. The third computing mechanism calculates amount of progress characteristics indicating the extent of the probable disease based on the morphological information and functional information.
