Abstract (in Japanese) (See Japanese page) 
(in English) To improve detection accuracy for small lesion, it is desirable that a resolution of original volume data should be as high as possible. However, resolution of clinical image is limited due to hardware limitation or size of imaging range. Volume upsampling by interpolation may be used instead of high resolution volume data. In this short report, we investigated relation between voxel size after interpolation and detection accuracy by using cerebral aneurysm detection in MR angiograms based on voxel based classifier. In the experimental study with 83 clinical cases, the results show that volume upsampling by interpolation have potential to improve detection accuracy for small lesion.
