Abstract (in Japanese) (See Japanese page) 
(in English) In the treatment, it is effectively to recognize a blood vessel and internal organs shape from a Non-contrasting CT image for judgment to get the contrasting CT image or not.
In this paper, we suggest a method to extract a blood vessel and a kidney domain from a Non-contrasting CT image.
Because of this method, it makes semiautomatic extraction method without lettering by the manual labor.
At first, we set the processing domain with the bone domain by MIP.
Next, we renew the pixel value by the setting of the opacity to make contrast with a blood vessel and the other domain cleary.
Finally, we extract a blood vessel and a kidney domain with three-dimensional labeling.
In addition, we suggest the removal method of the false extraction part of the blood vessel with the extraction shape filter.
As the result, it enables the extraction of the blood vessel and a kidney domain with several thresholds and extraction objects.
