<P>PROBLEM TO BE SOLVED: To provide a medical image processing device capable of forming a shaded three-dimensional image preventing artifacts being generated even when a subject is extended off the reconstruction field. <P>SOLUTION: Image reconstruction is made for a portion of a subject and the reconstruction field is designated for generating a tomographic image. Then X-ray transmission data acquired by photographing via X-ray CT device is read (S1). Based on the X-ray transmission data, image is reconstructed for generating the tomographic image(S2). Next, a surrounding region including the boundary line of the reconstruction field in the tomographic image is set as an objective field to be processed (S3). A smoothing process is executed based on the density value of the pixel of the object field to be processed(S4). The third-dimensional image shaded based on the tomographic image smoothing processed is generated and displayed(S5). <P>COPYRIGHT: (C)2007,JPO&INPIT |
