Abstract: A medical image processing device of an embodiment includes a comparator and a position determination region determiner. The comparator compares a first image obtained by photographing a patient with a comparative image which is an image used in previous radiation treatment and in which a valid region used in position alignment in the radiation treatment is designated. The position determination region determiner determines a position determination region similar to the valid region included within the first image on the basis of a comparison result of the comparator.

Abstract: According to an embodiment, a medical image processing device includes a first image acquirer, a second image acquirer, a treatment error acquirer, a difference calculator, and a differential statistical quantity calculator. The first image acquirer acquires a first fluoroscopic image of a patient. The second image acquirer acquires a second fluoroscopic image photographed at a timing different from the first fluoroscopic image. The treatment error acquirer acquires a treatment error occurring when an alignment process is performed or a treatment error occurring in treatment. The difference calculator calculates a difference image between the second fluoroscopic image to which the virtual perturbation is applied at the position of the patient shown therein based on the treatment error and the first fluoroscopic image.

Abstract: The present invention provides an ink jet printing apparatus that can substantially prevent possible variation in the color of an image on a print medium discharged from an ink jet printing apparatus. A drying condition is determined under which the color of the image varies until the color of the image becomes a target one having a color difference ?E of at most 3 from a stable color with substantially no temporal variation. The image is dried according to the drying condition. The print medium is then discharged from the printing apparatus. This enables variation in the color of the image on the print medium discharged from the printing apparatus to be prevented from exceeding 3 in terms of color difference ?E. As a result, a user can be prevented from perceiving variation in color.
