20100201865 | IMAGING METHOD FOR USE WITH VARIABLE CODED APERTURE DEVICE AND IMAGING APPARATUS USING THE IMAGING METHOD - Provided are an imaging method for use with a variable coded aperture filter and an imaging apparatus using the imaging method. The variable coded aperture filter includes a plurality of regulated patterns which may be properly selected, and an image obtained via a certain pattern of the variable coded aperture filter may be processed by a deconvolution method related to the certain pattern. The patterns in the variable coded aperture filter have different aperture degrees from each other so as to adjust an exposure amount, and accordingly, a subject which is extremely bright or extremely dark may be photographed and depth information and focus information may be obtained from the photographed image. Therefore, images of high image quality may be obtained in a large range of brightness variation. | 08-12-2010 |
20120113231 | 3D CAMERA - A three-dimensional (3D) camera and a method of operating the same are provided. The 3D camera includes: a first photographing lens unit; a first image sensor which obtains first image information of an object through the first photographing lens unit; a beam division unit disposed on an optical path between the first photographing lens unit and the first image sensor and which propagates light along a first path on which the first image sensor is positioned and along a second path that is different from the first path; a second photographing lens unit disposed on the second path; a second image sensor which obtains second image information of the object through the first photographing lens unit and the second photographing lens; and an image processing unit which generates 3D image information from the obtained first image information and the obtained second image information. | 05-10-2012 |
20120249839 | NON-REAL TIME IMAGE PROCESSING METHOD, IMAGE CAPTURING APPARATUS APPLYING THE SAME, AND IMAGE PROCESSING SYSTEM - An image processing method, an image capturing apparatus applying the same, and an image processing system. The image processing method includes capturing an image, generating intermediate data by primarily processing the captured image, generating final processing data including instructions to initiate a final process to convert the intermediate data into final data, and transmitting the intermediate data and the final processing data to an external image processing apparatus to perform the final process. Accordingly, an image quality of the image is improved as compared to an image quality of a final image processed in real time by a conventional image capturing apparatus, and a variety of functions can be provided. | 10-04-2012 |
20130121458 | COMPUTED TOMOGRAPHY APPARATUS AND CONTROL METHOD FOR THE SAME - A computed tomography apparatus and a method for controlling the same are provided. The apparatus is capable of switching between a high energy mode and a low energy mode at a high speed using a filter that rotates at a high speed. The computed tomography apparatus includes an X-ray generator which generates and irradiates X-rays toward a subject, an X-ray filter which includes at least one filter member, a driver which rotates the X-ray filter such that the filter members are selectively disposed in an irradiation path of X-rays generated by the X-ray generator, a detector which detects the X-rays that are transmitted to the subject, and a host apparatus which obtains X-ray images by using detected X-rays, separates the obtained X-ray images based on filter members to which the corresponding X-rays are transmitted, and reconstructs the images by using X-ray images of the identical filter member. | 05-16-2013 |
20140119494 | MEDICAL IMAGING APPARATUS AND METHOD OF PROVIDING OPERATIONAL INFORMATION OF GANTRY INCLUDED IN THE SAME - A medical imaging apparatus and/or method includes a gantry, a control unit, and a display unit. The gantry has a source for generating an X-ray and a detector for detecting the X-ray passing through an object. The gantry allows the source and the detector to rotate around the object. The control unit obtains operational information of the gantry. The display unit outputs the obtained operational information of the gantry. | 05-01-2014 |
20140119508 | COLLIMATOR MODULE, RADIATION DETECTOR HAVING COLLIMATOR MODULE, RADIOLOGICAL IMAGING APPARATUS HAVING COLLIMATOR MODULE, AND CONTROL METHOD OF RADIOLOGICAL IMAGING APPARATUS - A collimator module which may be disposed in a radiation detector of a radiological imaging apparatus using the collimator module may include a first collimator having a plurality of openings, through which radiation having passed through an object passes, and a second collimator located below the first collimator and having a plurality of openings, through which radiation having passed through the first collimator passes. The first collimator or the second collimator is designed so as to be movable or rotatable relative to the second collimator or the first collimator. Through movement of the first collimator or the second collimator, the size of a passage region that allows radiation having passed through the object to pass through the first collimator or the second collimator is adjustable. | 05-01-2014 |
20140348301 | METHOD AND APPARATUS FOR ACQUIRING PLURALITY OF X-RAY FOCUSES - A method and apparatus of acquiring a plurality of focal spots for X-rays. The method includes radiating an electron beam from a cathode of a magnetic field generating apparatus toward a movable anode of the magnetic field generating apparatus, and irradiating a target with an X-ray that is produced from the radiated electron beam by the anode. The anode comprises an inclined side in which a part of the inclined side protrudes, and the plurality of focal spots for X-rays are acquired based on the radiated electron beam and the inclined side. | 11-27-2014 |
20150208981 | INFORMATION PROVIDING METHOD AND MEDICAL DIAGNOSIS APPARATUS FOR PROVIDING INFORMATION - A method of providing information for magnetic resonance imaging (MRI) includes: performing an imaging of a patient by executing a sequence including a plurality of protocols; and providing, to the patient, threshold related information about a motion of the patient which corresponds to a currently executed protocol, of the plurality of protocols. | 07-30-2015 |
