  • Publication number: 20100088593
    Abstract: When a reception unit in an X-ray image reception system receives an image and additional information for the image from an X-ray image transmission system, the received additional information is sent to a resend setting determination unit. The resend setting determination unit determines a resend setting based on the received additional information and information acquired from a database and transmits the result to a reception completion determination unit. A packet loss determination unit determines packet loss in data received from the reception unit and transmits the result to the reception completion determination unit. The reception determination completion unit sends the results to the resent setting determination unit and the packet loss determination unit to the resend request unit. The resend request unit sends a resend request to the X-ray image transmission system based on the information from the reception unit and the result determined by the reception completion determination unit.

  • Publication number: 20090136000
    Abstract: An imaging apparatus in which positions of an X-ray image and optical image of a subject can be brought into registration with each other is provided. A half-mirror is provided between the X-ray source and subject and is configured to pass X-rays and reflect visible light. A TV camera captures the optical image of the surface of the subject reflected by the half-mirror. A display unit displays the optical image captured by the TV camera together with a reference mark indicating the reference position of this optical image, and displays, in superimposed form, an X-ray image obtained by capturing a prescribed reference object as a subject by using an X-ray imaging unit. An adjusting unit adjusts position and attitude of an X-ray detector in such a manner that the reference object displayed by the display unit will coincide with the reference mark.

  • Publication number: 20090103676
    Abstract: In a display control apparatus, an image receiving portion receives a plurality of images sequentially transmitted from an X-ray imaging apparatus based on a transmission order determined by a transmission-order determining portion, and a capture-order information receiving portion also receives, from the X-ray imaging apparatus, capture-order information indicating a capture order in which each of the images was captured by the X-ray imaging apparatus. The images received by the image receiving portion are stored in an image storage memory. A display controller controls displaying of the images stored in the image storage memory on a display apparatus based on a transmission order for transmitting the images or the capture-order information in accordance with an input imaging condition and an operating status of the X-ray imaging apparatus.

  • Publication number: 20090060309
    Abstract: A radiation image processing apparatus which processes non-spiral projection data obtained by radiation imaging performed by rotating a radiation generator and a two-dimensional radiation detector relative to a subject reconstructs the non-spiral projection data into first volume data subjected to an averaging process in a direction of a rotation axis of the rotation and second volume data not subjected to the averaging process. The radiation image processing apparatus performs planar reconstruction calculation using the first volume data to generate a cross section image in a first plane perpendicular to the direction of the rotation axis and performs planar reconstruction calculation using the second volume data to generate a cross section image in a second plane parallel to the direction of the rotation axis. The resulting cross section images are displayed on a display apparatus.

  • Publication number: 20080151070
    Abstract: The invention provides an image capture and display control apparatus that includes an imaging control unit that operates an image capturing unit at a first time interval so as to obtain a captured image with the image capturing unit and a display control unit that displays the captured image on a display unit, which operates at a second time interval. The apparatus changes at least one of an image capture start timing of the image capturing unit and a processing time from the start of image capturing by the image capturing unit until entering a standby state in which the captured image can be displayed by the display unit, so as to shorten a display delay time, which is caused by the second time interval, from the start of operation by the image capturing unit until display of the image data by the display unit.

  • Publication number: 20060265252
    Abstract: Processing of searching for personal information and image processing parameters specified by image identification information (S31) and specifying readable elements of the readout personal information to be transmitted to a user terminal is executed (S32). Of the elements contained in the personal information searched in step S31, the elements specified in step S32 are read out (S33). Medical image data specified by image identification information is searched for and subjected to image processing using the image processing parameters found in step S31 (S34). The elements read out in step S33 are added to the medical image data which has undergone image processing (S35), and the medical image is transmitted to the user terminal (S36).
