20090220140 | IMAGE PROCESSING METHOD AND APPARATUS, AND RADIATION IMAGE PHOTOGRAPHING/PROCESSING METHOD AND APPARATUS - Acquiring radiation image data representing a radiation image of a subject photographed using a radiation exposure field aperture, acquiring information of a radiation exposure field area determined by the exposure field aperture and relating it to the radiation image data based on the information, sequentially detecting pixel data of pixels from adjacent to the boundary line of the exposure field area toward the inner side thereof in the radiation image data, sequentially determining if the values of the detected pixel data are not greater than a predetermined threshold value, terminating the detection at a point where the value of the detected pixel data is greater than the predetermined threshold value, and performing a blackening process on pixel data of a pixel outside of the exposure field area and pixel data of a pixel whose value is determined to be not greater than the predetermined threshold value. | 09-03-2009 |
20110021947 | RADIOGRAPHIC IMAGE CAPTURING APPARATUS - In a radiographic image capturing apparatus, an object to be examined is compressed and secured between a compression plate and an image capturing base, at a position off-center from a central position of the image capturing base near a subject in a direction along the subject. An opening is defined in the compression plate so as to confront the object to be examined in the off-center position. The radiation source irradiates the object to be examined as well as the opening with radiation from a central angle of the radiation source, which is aligned with a vertical axis of the image capturing base, and which passes through the central position from a predetermined angle that is angularly spaced from the central angle about the central position. | 01-27-2011 |
20120027168 | RADIOLOGICAL IMAGE RADIOGRAPHING AND DISPLAYING METHOD AND RADIOLOGICAL IMAGE RADIOGRAPHING AND DISPLAYING APPARATUS - It is possible to always display a stereoscopic image obtained by observing a subject from the front side even when the position of the subject is shifted. A radiological image radiographing and displaying method includes irradiating a subject with radiation emitted from two focal positions in two different radiographing directions, detecting a radiological image in each radiographing direction resulting from the irradiation with the radiation by the use of a radiological image detector, displaying a stereoscopic image using the two detected radiological images, acquiring position information of the subject in an extending direction of a straight line connecting two points obtained by projecting the two focal positions onto the radiological image detector, and changing the two radiographing directions based on the acquired position information. | 02-02-2012 |
20120027169 | RADIOLOGICAL IMAGE RADIOGRAPHING AND DISPLAYING METHOD AND APPARATUS - A stereoscopic image radiographing apparatus performing both an equal-magnification radiographing operation and an enlarged radiographing operation displays a stereoscopic image with a magnitude of parallax suitable for both radiographing operations without changing two focal positions of radiation. Two radiological images are relatively moved and displayed in a parallax direction which is obtained by projecting an extending direction of a straight line connecting two focal positions onto the corresponding radiological image based on the angle formed by two radiographing directions of two radiological images constituting the stereoscopic image and the enlargement ratio thereof. | 02-02-2012 |
20120027170 | RADIOLOGICAL IMAGE CAPTURING AND DISPLAYING METHOD AND APPARATUS - Even when one side of a radiological image detector is inclined with respect to a straight line linking two focal positions of radiation, an appropriate stereoscopic image is displayed. The amount d of shift between two radiological images in a direction perpendicular to a parallax direction is acquired and a stereoscopic image is displayed using the two radiological images which are relatively shifted in the direction perpendicular to the parallax direction so that the acquired amount d of shift is reduced. | 02-02-2012 |
20120069957 | RADIOLOGICAL IMAGE DISPLAYING DEVICE AND METHOD - Diagnosis using a tomographic image and a stereoscopic image can be easily performed. A reconstruction unit generates a tomographic image from a plurality of radiological images with different radiographing directions, which is stored in a radiological image storage unit. A display control unit displays a stereoscopic image using a standard radiological image and a reference radiological image, among the plurality of radiological images, on a monitor. In this case, the tomographic image is superimposed on the stereoscopic image. | 03-22-2012 |
20120277625 | RADIOGRAPHIC IMAGE CAPTURING APPARATUS - A radiographic image capturing apparatus includes a compression member, which is displaceable with respect to a holding member that holds a target object to be examined. The compression member is displaced toward the holding member for compressing the target object held by the holding member while the compression member is tilted with respect to the holding member along lateral directions of the target object as viewed in front elevation. | 11-01-2012 |
20120321034 | RADIOLOGICAL IMAGE RADIOGRAPHING APPARATUS AND METHOD - Deterioration of the image quality of a displayed image is prevented when displaying one image, such as a tomographic image or a stereoscopic image, based on a plurality of radiological images acquired by performing radiographing multiple times in order to display a tomographic image or a stereoscopic image. A feature amount calculation unit calculates feature amounts representing the image quality, such as density histograms, for a plurality of radiological images for generating a tomographic image acquired by tomosynthesis. A determination unit compares the feature amounts of the plurality of radiological images and based on the comparison result, and then determines whether or not an abnormal radiological image with different image quality is present in the plurality of radiological images. When an abnormal radiological image is present, a reconstruction unit generates a tomographic image by performing reconstruction after excluding the abnormal radiological image from the plurality of radiological images. | 12-20-2012 |
