Description

  The present invention relates to a radiation imaging system using a solid-state imaging device or the like.

  In recent years, digital radiography systems have been used for radiography for medical diagnosis. In general, this type of radiation digital imaging system includes a radiation imaging apparatus and a radiation detector.

  The radiation imaging apparatus is an apparatus that manages imaging information such as setting of imaging conditions and confirmation of a captured image, acquires a captured image from a radiation detector, and controls driving of the radiation detector. In addition, the radiation detector uses a phosphor to convert radiation into visible light proportional to its intensity, then converts it into an analog electrical signal using a photoelectric conversion element, and further converts it into an electrical signal via an A / D conversion circuit. The signal is converted into a digital signal. A photoelectric conversion element consists of solid-state image sensors, such as an amorphous silicon, for example, and comprises the two-dimensional sensor by arranging a photoelectric conversion element in a matrix form.

  Usually, the radiation imaging apparatus and the radiation detector are connected via a communication cable, and the radiation imaging apparatus controls the radiation detector via this communication cable. Therefore, there exists a problem that the portability of a radiation detector will be restrict | limited to the range which a communication cable reaches. Further, there is a problem that the communication cable becomes an obstacle when the radiographer makes contact with the radiation detector on the subject.

  In order to solve these problems, a method of adopting wireless communication such as UWE (Ultra Wide Band) has been proposed as a communication method between the radiation imaging apparatus and the radiation detector. However, simply changing from a wired communication cable to a wireless communication causes a new problem. For example, when there are a plurality of radiation detectors, operation control of the apparatus becomes complicated between the radiation imaging apparatus and the radiation detector. Alternatively, it is difficult and difficult for the imaging technician to handle the radiation detector. In the worst case, imaging control is performed with respect to a radiation detector different from the radiation detector in contact with the subject, and the imaging engineer is not aware of this and cannot obtain a desired radiation image. The situation is also conceivable.

  When such a situation occurs, radiography of the subject is performed again in order to obtain a desired radiographic image. In other words, the risk of such a problem is a very serious and serious problem in the field where reliability of operation control, safety of the imaging engineer / subject, etc. are emphasized as in radiography.

  With respect to the above-described problem, Patent Documents 1 and 2 disclose a method for preventing a radiation detector from being mistaken.

JP 2004-141473 A JP 2009-63999 A

  However, in Patent Document 1, it is conceivable that, when a recording engineer removes a recording medium from a mistaken radiation detector and inserts it into an imaging apparatus, radiography is started while the radiation detector is mistaken.

  Further, in Patent Document 2, there is a possibility that the radiation detector may be mistaken while the radiation imaging apparatus is performed after the radiographer attaches the subject identifier storage medium to the radiation detector. Furthermore, in order to use the radiation imaging apparatus, it is necessary to change the hospital operation mode to the operation mode using the subject identifier storage medium.

  Patent Documents 1 and 2 both require an imaging engineer to mount a storage medium.

  An object of the present invention is to solve the above-mentioned problems, and improve the reliability of operation control and the safety of imaging technicians and subjects, which are concerns when radio communication is applied to the radiation imaging system. Is to provide.

  In order to achieve the above object, a radiation imaging system according to the present invention includes a radiation detector that captures a radiation image of a subject based on radiation transmitted through the subject, an imaging gantry on which the radiation detector is mounted, and the radiation detection A radiation imaging apparatus for controlling the instrument, and a setting communication device provided in the imaging gantry for transmitting the setting information of the radiation detector to the radiation imaging apparatus, and the setting information transmitted from the setting communication device A radiography system that performs wireless communication between the radiography apparatus and the radiation detector based on the radiation imaging apparatus, the radiography apparatus detecting the radiation detector disposed on the imaging gantry, The photographing apparatus is characterized by instructing an operation of the next stage.

  According to the radiation imaging system of the present invention, radiation imaging is performed using a radiation detector and a radiation imaging apparatus mounted on an imaging table such as an operating table or a supine / stand-up imaging frame. Prevent mistakes in detector detection. At the same time, it is possible to eliminate the operation of attaching the storage medium to the photographing engineer, and the reliability of the operation control, the safety of the photographing engineer / subject, and the like are improved.
