Mission †

Goal of the medical image analysis laboratory is the research, development and validation of image processing algorithms and computer-aided diagnosis systems that enable the objective and reproducible evaluation of anatomical and pathological structures in medical images.

Main research topics †

Segmentation algorithms †

• Simultaneous segmentation of 12 organs in an upper abdominal non-contrast CT image.
  
  

• Pancreas segmentation from contrast enhanced CT images.
  

• Liver tumor segmentation from a contrast enhanced CT image [It won 1st prize in the international competition 2008. see "News"].
  
  

CAD †

• PET and CT images.
• Autopsy imaging. (see also the Japan society of Autopsy imaging)
