20080239115 | Image processing device, method, and program storage medium - There is a provided an image processing device having: a storage section for storing defective pixel information expressing defective pixels of an image pickup element; a correction section that, on the basis of the defective pixel information, carries out correction of defective pixels on an image captured by the image pickup element; a point defect detector that, on the basis of a first image for defect detection which has not been subjected to defective pixel correction, detects point defects of the image pickup element in accordance with point defect detecting conditions; a line defect detector that, on the basis of a second image for defect detection which has not been subjected to defective pixel correction, detects line defects of the image pickup element in accordance with line defect detecting conditions; and a defective pixel information register storing the results of detection. | 10-02-2008 |
20100252740 | RADIATION IMAGING APPARATUS AND RADIATION IMAGING METHOD - Placement of a marker is performed efficiently, when performing a plurality of radiation imaging operations of a subject with different imaging angles. An operator inputs a region of interest within a subject on a bed, via an operating section. The region of interest and a peripheral region thereof are set as an irradiation range, and the marker is placed in the peripheral region. A radiation source control section causes a radiation source to emit radiation toward the subject within the set irradiation range. Radiation which passes through the subject is obtained by a radiation image detector as a radiation image. | 10-07-2010 |
20100322376 | RADIATION IMAGING APPARATUS AND METHOD - A plurality of radiation images of an object are acquired by iterating the steps of: beginning driving of a rotation driving unit at the time at which a breathing signal having been detected by a breathing sensor has come into a predetermined state, performing a radiation imaging operation with a set of a radiation source and a radiation detector at the time, at which the heart has come into a predetermined state, in accordance with a heartbeat signal having been detected by a heartbeat sensor within a rotation driving period, during which the rotation driving unit performs the rotation driving, and ceasing the rotation driving of the rotation driving unit at the time at which the breathing of the object has come into a state other than the predetermined state. | 12-23-2010 |
20120045110 | METHOD OF ENCODING A RADIOGRAPHIC IMAGE SIGNAL, METHOD OF DECODING A RADIOGRAPHIC IMAGE SIGNAL, RADIOGRAPHIC IMAGE DETECTION DEVICE AND RADIOGRAPHIC IMAGE SIGNAL GENERATION DEVICE - From a radiation detecting unit for detecting a radiographic image of a subject by receiving radiation transmitted through the subject, a radiographic image signal representing the radiographic image is read out, and information about an imaging operation carried out to obtain the radiographic image of the subject is obtained. The radiographic image signal is encoded with using key information based on the obtained information about the imaging operation to generate an encoded radiographic image signal, and the encoded radiographic image signal is outputted as a radio communication signal. | 02-23-2012 |
20130208860 | RADIATION IMAGE DETECTING DEVICE, ELECTRONIC CASSETTE, AND RADIATION IMAGING SYSTEM - An AEC signal is transmitted and received always in a wireless manner between a wireless communicator of an electronic cassette and a wireless communicator of a control device, regardless of the presence or absence of wired communication. If communication failure occurs in the wired communication and X-ray image data cannot be transmitted in a wired manner, a memory of the electronic cassette temporarily stores the X-ray image data. Since the AEC signal is wirelessly transmitted, X-ray imaging is continued even if the wired communication is unusable. A cause of the communication failure is more easily identified in wireless communication than in the wired communication. Thus, even if the communication failure occurs in the wireless communication, the wireless communication quickly recovers from the failure and downtime of an X-ray imaging system does not become too long. | 08-15-2013 |
20150087978 | COMPLEX DIAGNOSTIC APPARATUS, COMPLEX DIAGNOSTIC SYSTEM, ULTRASOUND DIAGNOSTIC APPARATUS, X-RAY DIAGNOSTIC APPARATUS AND COMPLEX DIAGNOSTIC IMAGE-GENERATING METHOD - An optimal value calculator calculates, based on angle information obtained from a first angle sensor provided in an ultrasound probe, the direction of transmission of an ultrasonic beam transmitted from the ultrasound probe, and the radiation source optimal angle of a radiation source at which the direction of radiation from the radiation source is substantially parallel to the calculated direction of transmission of the ultrasonic beam and the optimal detection angle of a radiographic image generator at which the normal of a detection surface of the radiographic image generator is substantially parallel to the calculated direction of transmission of the ultrasonic beam. | 03-26-2015 |
20150374263 | MEDICAL IMAGE PROCESSING DEVICE, METHOD FOR OPERATING THE SAME, AND ENDOSCOPE SYSTEM - First RGB image signals are inputted. Color difference signals Cr and Cb are calculated from the first RGB image signals. In a feature space formed by the color difference signals Cr and Cb, a first process and a second process are performed. In the first process, coordinates which correspond to the first, second, and third observation areas are moved in a parallel manner such that the coordinates which correspond to the second observation area are moved to a reference area that contains the origin point. In the second process, the coordinates which correspond to the first observation area and the coordinates which correspond to the third observation area are moved away from each other. | 12-31-2015 |
20150379698 | MEDICAL IMAGE PROCESSING DEVICE, METHOD FOR OPERATING THE SAME, AND ENDOSCOPE SYSTEM - First RGB image signals are inputted. Color difference signals Cr and Cb are calculated from the first RGB image signals. In a feature space formed by the color difference signals Cr and Cb, a first process is performed such that coordinates corresponding to a second observation area are moved to a reference area containing the origin point while coordinates corresponding to first and third observation areas are maintained unchanged. A second process is performed to move the coordinates corresponding to the first observation area and the coordinates corresponding to the third observation area away from each other. | 12-31-2015 |
