1. an image processing apparatus, is characterized in that, has:

  • To diffusion, standardized component, emphasizes that volume data and T2W volume data carry out standardization;

    First parametric image creation section, diffusion after the standardization received from above-mentioned standardized component is emphasized that volume data implements projection process thus carry out two-dimensional projection, the two-dimensional projection of volume data will be emphasized via diffusion and the projection diffusion that is made emphasizes that image is shown in display device;

    Mask creation section, judge that the diffusion after the standardization received from standardized component emphasizes that the signal intensity of volume data is whether in the scope determined by the threshold value predetermined, be made the mask of the calculating object for determine to project diffusion coefficient image and projection anisotropy ratio image thus;

    3D parametric image creation section, use the mask received from mask creation section to emphasize that volume data and T2W volume data carry out mask process to the diffusion received from standardized component, use the diffusion after mask process to emphasize that volume data and T2W volume data are to calculate three-dimensional diffusion coefficient image and anisotropy ratio'"'"'s image;

    Second parametric image creation section, two-dimensional projection'"'"'s process is implemented to the diffusion coefficient image obtained from 3D parametric image creation section and anisotropy image, thus be made projection diffusion coefficient image and projection anisotropy image, be made projection diffusion coefficient image and projection anisotropy image are shown in display device;

    With reference to image creation section, when have received the display instruction with reference to image from input equipment, be made projection diffusion coefficient image, the position corresponding with labelling on projection anisotropy image image being emphasized to the projection diffusion be made in the first parametric image creation section or is made in the second parametric image creation section carried out labelling and obtained desired by with reference to image;

    AndClinical database, required threshold value or the information such as parameter, clinical data for decision threshold when the mask of the data required for standardization and mask creation section of preserving standardized component is made;

    Above-mentioned first parametric image creation section is preserved projection and is spread the corresponding informance that the Data Position between body is emphasized in the diffusion after emphasizing image and standardization,The above-mentioned second parametric image creation section respective position of preserving the data on projection diffusion coefficient image and projection anisotropy image and the corresponding informance as the respective position on the diffusion coefficient image of volume data and anisotropy image,Obtain with reference to image creation section the corresponding informance preserved in the first parametric image creation section, the second parametric image creation section by above-mentioned when being made projection diffusion coefficient image, projection anisotropy image and projection diffusion and emphasizing image, thus detect and to emphasize in volume data with projection diffusion coefficient image, the anisotropy that projects image in diffusion and project and spread position corresponding to the labelling emphasized on image.
