Abstract: A console structure in an X-ray imaging system performs image processing of plural radiation images formed by an X-ray imaging apparatus having an active pixel area with pixels for detecting a radiation image of a body. The plural radiation images are formed by imaging one object in the body with a time interval. The console structure acquires the radiation images. An information controller obtains field information of a position of an exposure field which is associated with each one of the radiation images and automatically set in the active pixel area according to a position of the body being positioned for automatic exposure control in the X-ray imaging apparatus before imaging. A matching unit performs position matching according to the field information to match the position of the body in the plural radiation images between plural display images corresponding to respectively the plural radiation images.

Abstract: A first data taking section takes first detection results from a first wireless tag reader which detects the come and go of an electronic cassette into and out of a first service zone, and also takes second detection results from a second wireless tag reader which detects the come and go of an electronic cassette into and out of a second service zone. A first alert controller drives a first speaker to start an alert when the first alert controller determines on the basis of the first detection results that the electronic cassette has gone out the first service zone. After the start of alerting, the first alert controller stops driving the first speaker to interrupt the alert when first alert controller determines that the electronic cassette has come in either the first service zone or the second service zone.

Abstract: An electronic cassette is provided with a sensor panel, a housing, operation buttons, a head-bottom setting section, lamps and a memory. The sensor panel has a quadrangle imaging area, and detects an X-ray image of a patient. The housing houses the sensor panel. The operation buttons are disposed on the housing. When either one of the operation buttons is pushed down, the head-bottom setting section sets either one of adjoining two sides of the imaging area to be the head of the radiographic image in the display orientation. The display section is disposed on the housing, and displays which side is set by the head-bottom setting section to be the head of the radiographic image. The memory stores head-bottom setting information and the radiographic image in association with each other.

Abstract: An x-ray image detector monitors the intensity of incident x-rays to detect an end of radiation from an x-ray source when the x-ray intensity decreases to a threshold level or less. The x-ray intensity gets down to zero with a variable time lag from the start of decreasing, called radiation wave tail. Depending on the gradient of declivity in time curve of the decreasing x-ray intensity, calculated at the time when the end of radiation is detected, the x-ray image detector decides a delay time from the end-of-radiation detection time to a reading start time to start reading signal charges from the image detector. Thus, the reading start time may be adjusted to the point when the x-ray intensity gets down to zero, which will improve S/N ratio and prevent shading artifacts.

Abstract: In a cassette-type X-ray detection device, an X-ray detector and a self diagnostic circuit are contained in a cassette casing. When the cassette-type X-ray detection device gets a shock, the self diagnostic circuit is actuated. The self diagnostic circuit reads out from the X-ray detector an offset image being a dark current image, and analyzes the offset image. The self diagnostic circuit finds out an abnormal portion from the offset image, and diagnoses whether the X-ray detector is available, unavailable, or partly available based on the size and position of the abnormal portion. Shock detection and a diagnostic result are displayed on a touch panel provided in the cassette casing, and sent to a console device via a communication unit.
