Abstract:
An X-ray imaging system includes a plurality of electronic cassettes having FPDs. One of the plural electronic cassettes for use in imaging is selected by input operation. Control is performed in a first mode operation being normal for the electronic cassette selected in the selecting step. Control is performed in a second mode operation being auxiliary of which driving power is lower than in the first mode operation for one of the electronic cassettes in an unselected state in the selecting step. Assuming that irradiation of the radiation is detected in the second mode operation, error information is displayed in relation to selecting the electronic cassette in the selecting step. For example, the first and second mode operations are pixel reset in which charge stored in pixels are swept in an FPD.
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:
Useful material for making low-dose radiographing and an increase in the image quality compatible with each other is provided. An image analysis unit of a central server derives the granularity of a region of interest by analyzing an X-ray image transmitted from a client terminal. A storage processing unit stores the granularity, the X-ray image, and radiographing information in a storage device so as to be associated with each other. A search processing unit searches for the radiographing information, which is matched with search conditions designated from the client terminal, and granularity, which is associated with the radiographing information, from the storage device. A statistical data generation unit generates a scatter plot, which has granularity on the vertical axis and a radiation dose on the horizontal axis, as statistical data. The statistical data is transmitted to the client terminal and is displayed on a display of the client terminal.

The image analysis device includes: a radiographic image acquisition section; a dosage data acquisition section that acquires dosage data indicating, in a time-series manner, a dosage of radiation rays exposed to a specific position in an imaging area in a specific period; and a determining section that determines whether the dosage data has a first feature indicating a dosage variation as a plurality of radiation absorbing bodies and a radiation transmitting body disposed between adjacent radiation absorbing bodies pass through a space between the specific position and a radiation source, and determines that the radiographic image corresponding to the dosage data determined to have the first feature is a rocking grid use image captured by rocking a rocking imaging grid.
Abstract:
In a radiation image processing apparatus, method, and program, performing image processing based on scattered radiation, such as scattered radiation elimination processing, accurately by taking into account the influence of scattered radiation from an area adjacent to a processing target area. For this purpose, performing image processing on a radiation image captured by applying radiation to a subject based on scattered radiation generated by the subject. In this case, a processing target area which is the processing target in the radiation image is added with another area different from the processing target area in the radiation image. Then, the image processing based on scattered radiation is performed on the processing target area using the another area and the processing target area.
Abstract:
To provide a radiation image detecting device providing high responsivity and high precision of an emission start judgment, an electronic cassette has a panel unit and a control unit. The panel unit has a two-dimensional array of normal pixels for accumulating signal charge upon receiving X-rays and detection pixels for detecting the X-rays. A signal processing circuit periodically samples a dose signal, corresponding to an X-ray dose per unit of time, from the detection pixels. An emission start judgment unit performs based on the dose signals of the detection pixels a first judgment process for judging whether X-ray emission has been started, and a second judgment process for judging whether a result of the first judgment process is correct. The control unit sets a second sampling cycle SP2 used in the second judgment process longer than a first sampling cycle SP1 used in the first sampling process.

A radiographic image capture device includes a radiation detector and a determination section. The radiation detector includes a first sensor for radiographic image capture and a second sensor for radiation detection. The determination section determines whether or not radiation has been detected by the radiation detector based on a ratio of a first value obtained by the first sensor to a second value obtained by the second sensor.
