Ultrasonic diagnosis requires substantial experiences for both acquiring and reading echography. This paper describes a novel method for synthesizing ultrasound image with artifacts according to user's probe manipulation. The proposed method is a sample-based approach that stores pre-captured real echo images as a volume data set in which each voxel has multi-directional values. Output echography is synthesized by interpolating voxel values, considering spatial arrangement and directivity of the voxel values. Experimental results demonstrated spatially seamless echography synthesis and characteristic artifacts with various probe postures.
