20150094516 | MEDICAL IMAGE PROCESSING DEVICE, TREATMENT SYSTEM AND MEDICAL IMAGE PROCESSING METHOD - According to an embodiment, a medical image processing device includes a processor, and a memory. The memory that stores processor-executable instructions that, when executed by the processor, cause the processor to execute acquiring a first perspective image of a subject viewed in a first direction; setting a first region and a second region on the first perspective image, the first region including a first group of pixels around a target pixel, the second region including a second group of pixels, the second group including a pixel not included in the first group; calculating a likelihood of the target pixel, wherein the likelihood increases as a difference between pixel values included in the first group decreases and a difference between pixel values of the first group and the second group increases; and detecting a position of an object in the subject based on the likelihood. | 04-02-2015 |
20150117605 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to some embodiments, an image processor includes a perspective image generator, a perspective image acquirer, a corresponding point acquirer, a first calculator and a display image generator. The first calculator updates the position of the one or more first corresponding point on the first perspective image, based on a difference in position between the first and second perspective images. The display image generator generates a first display image including the first and second perspective images, the one or more first corresponding points updated on the first perspective image, and the one or more second corresponding points on the second perspective image. The perspective image generator changes the first direction into a third direction based on the difference in position between the first and second perspective images, and generates an updated one, viewed in the third direction, of the first perspective image. | 04-30-2015 |
20150154752 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to an image processor of one embodiment, a first acquirer acquires a first perspective image of a target, which has a first resolution. A second acquirer acquires a second perspective image of the target, which has a second resolution. A first image generator generates first and second display images respectively from the first and second perspective images. The first and third display images have a third resolution lower than at least one of the first and second resolutions. A first point acquirer acquires first and second corresponding points respectively on the first and second display images. A first corrector searches, on the second perspective image, a second image similar to a first image on the first perspective image, the first image including the first corresponding point, and changes, on the second perspective image, a position of the second corresponding point to a position of the second image. | 06-04-2015 |
20150154757 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to an image processor of one embodiment, a first acquirer acquires a first perspective image of a target viewed in a first direction. A second acquirer acquires a second perspective image of the target viewed in a second direction at a time different from when the first acquirer acquires the first perspective image. The second direction is substantially the same as the first direction. The second time is different from the first time. A point acquirer acquires first information indicating a first position of a first point on the first perspective image, and a second information indicating a second position of a second point on the second perspective image. An image generator generates an image that is based on the first and second perspective images, wherein a first coordinate of the first perspective image is changed so that the first point corresponds to the second point. | 06-04-2015 |
20150221099 | IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND IMAGING DEVICE - According to one embodiment, an image processing device includes a calculator, and an output interface. The calculator acquires image information including a value of a first pixel and values of peripheral pixels disposed around the first pixel. The first pixel is disposed at a first position and has a first color. The calculator calculates a first feature quantity of the value of the first pixel relating to a difference between the value of the first pixel and the values of the peripheral pixels. The calculator calculates a value relating to a second color at the first position by using a first filter coefficient and the values of the peripheral pixels. The first filter coefficient is determined according to the first feature quantity and the first position. The output interface outputs the calculated value relating to the second color at the first position. | 08-06-2015 |
20150222920 | IMAGE PROCESSING DEVICE, IMAGING DEVICE, AND IMAGE PROCESSING METHOD - According to one embodiment, an image processing device includes a calculator. The calculator acquires image information including a reference frame and a plurality of target frames. The calculator estimates a first motion of the target frames with respect to the reference frame and derives a first stored frame by adding the target frames each of which positions was adjusted based on the first motion. The calculator estimates a second motion of the target frames with respect to the reference frame and derives a second stored frame by adding the plurality of the target frames each of which position was adjusted based on the second motion. The estimation of the second motion is different from the estimation of the first motion. The calculator generates an output frame using the first stored frame and the second stored frame. | 08-06-2015 |
20150279111 | IMAGE PROCESSOR, TREATMENT SYSTEM, AND IMAGE PROCESSING METHOD - According to some embodiments, an image processor of an embodiment has an imaging parameter acquirer and a virtual perspective image generator. The imaging parameter acquirer acquires an imaging parameter which is used by a radiographic imaging apparatus in capturing a perspective image of a target. The virtual perspective image generator determines a method of generating a virtual perspective image from volume data acquired by capturing the target in accordance with the imaging parameter. The virtual perspective image generator generates the virtual perspective image from the volume data in accordance with the determined method. | 10-01-2015 |
20150326786 | IMAGE PROCESSING DEVICE, IMAGING DEVICE, AND IMAGE PROCESSING METHOD - According to one embodiment, an image processing device includes memory and a calculator. The memory stores a first storage image. The calculator stores at least a portion of a target image in the first storage image. The calculator determines to set a reference image to be the target image when a relationship between the reference image and the target image satisfies a determination condition, the storing being based on a motion vector between the reference image and the target image. | 11-12-2015 |
