Abstract: An image processing device includes an image receiving section that receives two medical images, which are imaged at different imaging times, of a same examination object; a time difference acquiring section that acquires a difference between the imaging times of the two images; a global matching section and a local matching section that execute a matching process for the two medical images upon setting of a parameter value. The matching process causes the two images to match each other by moving and deforming one of the two images. The amount of the movement or the deformation necessary for matching is in an application range that is dependant on the parameter value. Also provided is a parameter setting section that sets a value corresponding to the difference between the imaging times acquired in the time difference acquiring section to the processing section as the parameter value.

Abstract: An image processing device has: an image acquisition section that acquires a plurality of photographic images obtained by photographing the same subject at different photography times; and a part identification section that identifies a portion where a predetermined part among parts that form the subject in the photographic images appears. The device further has: a first processing section that applies first matching processing, which matches two images by transforming one or both of the two images, to two of the plurality of photographic images; and a second processing section that applies second matching processing, which matches two images by transforming one or both of the two images and whose application range of the amount of transformation required for matching is different from that of the first matching processing, to the portion identified by the part identification section in the two of the plurality of photographic images.

Abstract: A method for preparing crystalline calcium pantothenate, which comprises the step of allowing a homogenous mixture containing crystalline calcium pantothenate and amorphous calcium pantothenate to absorb moisture. The aforementioned method comprises, for example, the following steps of (1) mixing crystalline calcium pantothenate and amorphous calcium pantothenate to prepare a homogenous mixture; and (2) allowing the homogenous mixture obtained in the above step (1) to absorb moisture, and enables efficient preparation of crystalline calcium pantothenate with extremely low hygroscopicity.

Abstract: A method for preparing nondeliquescent crystalline calcium pantothenate which comprises the steps of: (1) stirring a supersaturated aqueous solution containing calcium pantothenate in a ratio of 60% (W/W) or more, for example, by using a grinder mill, to obtain a crystal suspension; and (2) drying the suspension. A nondeliquescent crystalline calcium pantothenate which is substantially free from an organic solvent can be efficiently prepared.
