  • Patent number: 10251617
    Abstract: An X-ray fluoroscopic imaging apparatus controls movement of shield plates so that a length of a first pre-image in an x direction is larger than a length of a strip image. A capturing position of the first pre-image is adjusted so that an upper end of the first pre-image matches an upper end of a capturing range of a long image. Thus, where a long region is set on the basis of the first pre-image at present, it is possible to check whether a desired X-ray image is included in a strip image. It is possible to correct a position of an imaging system to an appropriate position as an imaging start point by referring to an X-ray image included in the first pre-image having a large amount of information. Therefore, it is possible to acquire a long image appropriate for diagnosis through slot imaging using this apparatus.

  • Patent number: 10057460
    Abstract: Techniques for proving digital photograph authorship using ECG biometrics are described. Electrodes are located on the exterior of a digital camera and are electrically coupled to an ECG circuit. When a photographer holds the camera with both hands, the electrodes detect electrical voltages from the photographer's hands and the ECG circuit produces a digital ECG signal. When the photographer uses the digital camera to capture a photograph, the camera's stenographic engine uses a stenographic key to embedded the ECG signal into the raw image file, producing a watermarked image. The camera's cryptographic engine uses a cryptographic key to encrypt the watermarked image to produce an encrypted image. If a dispute arises regarding authorship of the photograph, the stenographic and cryptographic engines convert the encrypted image into the raw image file and the photographer's ECG signals, which are compared to the ECG signals of the disputed author(s).

  • Patent number: 10022101
    Abstract: In the present invention, a method and associated system is provided that produces a new sequence of combined X-ray/fluoro images obtained in synchrony with intravascular dataset/images. This synchronization is based on the time tags recorded at the acquisition of one dataset of the X-ray/fluoroscopic images and the intravascular images/datasets and the cardiac cycle correspondence between the combined X-ray/fluoro datasets/images. The combined X-ray/fluoro and intravascular sensor images provided in the method for each position of intravascular measurement/slice along the blood vessel allows the physician the ability to determine the planned position of the treatment, e.g., a stent, in the X-ray/fluoro images based on the intravascular images, and allows an accurate assessment of the target/lesion location in the X-ray/fluoro images during treatment.

  • Patent number: 9993213
    Abstract: An X-ray imaging apparatus displays a bone or soft tissue image of an X-ray image, which corresponds to a region selected by a user, thereby reducing a diagnosis time. In addition, an X-ray imaging system transmits a first energy X-ray image and a second energy X-ray image to a central image management system, and a user control apparatus receives the images from the central image management system and displays a bone or soft tissue image corresponding to the selected region, thereby reducing burden imposed on server capacity of the central image management system as well as reducing a diagnosis time.

  • Patent number: 9984210
    Abstract: A method for performing a job list of radiographic recordings indicated in a radiographic information systems includes communicating the job list to a mobile apparatus, e.g. a smartphone, whereby, in a first step, a peer-to-peer communication is set up between the radiographic information system and the mobile apparatus by a Near Field Communication technique, whereupon the job list is transmitted to the mobile apparatus via a WIFI peer-to-peer communication. A radiographer then completes the job list by using, inter alia, a self-triggering direct radiographic panel and a radiographic generator.

  • Patent number: 9929882
    Abstract: A receiver for a wireless device. A channel estimation module is configured to calculate a first channel estimate on a first tone of a data packet and calculate a second channel estimate on a second tone of the data packet. A phase roll estimation module is configured to calculate a conjugate of the second channel estimate and calculate, using the first channel estimate and the conjugate of the second channel estimate, an estimate of a phase roll caused by an error in symbol timing of the data packet. The phase roll corresponds to a difference between phases across adjacent tones of the data packet. The phase roll estimation module is further configured to calculate, based on the estimate of the phase roll, a timing advance to be applied to the symbol timing of the data packet. The timing advance corresponds to a number of samples of the data packet.
