엑스선 제너레이터 시스템X-ray generator system
본 발명은 의료용, 동물용 및 산업용 등에 사용되는 디지털 엑스선 사진촬영장치에 사용할 수 있는 엑스선 제너레이터시스템에 관한 것으로서, 특히 엑스선 제너레이터에 무선통신모듈을 탑재하고, 엑스선 검출기와 무선으로써 데이터 통신을 하도록 함으로써, 디지털 엑스선 촬영장치의 설치가 용이하고, 우수한 엑스선 영상을 획득할 수 있을 뿐만 아니라, 유지보수에 따른 편의성을 극대화하도록 하는 무선통신모듈이 구비된 엑스선 제너레이터 시스템에 관한 것이다.The present invention relates to an X-ray generator system that can be used in a digital X-ray photographing apparatus used in medical, animal and industrial use, and more particularly, by mounting a wireless communication module in the X-ray generator and performing data communication wirelessly with an X-ray detector, The present invention relates to an X-ray generator system equipped with a wireless communication module that is easy to install a digital X-ray photographing apparatus, to obtain excellent X-ray images, and to maximize the convenience of maintenance.
일반적으로, 디지털 엑스선 촬영장치는 도 1에 도시한 바와 같이, 생성된 엑스선을 조사{照射)하는 엑스선관(1); 상기 엑스선관(1)에서 조사한 엑스선을 촬상(撮像)하여 디지털 영상데이터를 만드는 엑스선검출기(2); 엑스선을 발생시키기 위하여 엑스선관(1)에 전력을 공급하고,엑스선관 전압, 엑스선관 전류, 조사시간 등을 제어하는 엑스선제너레이터(3); 및 상기 엑스선검출기(2)에서 얻어진 디지털 영상데이터를 연산처리하여 디지털 영상을 생성시키는 컴퓨터(4)를 포함하여 구성된다.In general, the digital X-ray imaging apparatus includes an X-ray tube 1 for irradiating the generated X-rays, as shown in FIG. 1; An X-ray detector (2) for imaging digital X-rays radiated from the X-ray tube (1) to produce digital image data; An X-ray generator 3 for supplying power to the X-ray tube 1 to generate X-rays, and controlling the X-ray tube voltage, the X-ray tube current, the irradiation time, and the like; And a computer 4 for computing the digital image data obtained by the X-ray detector 2 to generate a digital image.
따라서, 상기와 같이 구성되는 종래의 디지털 엑스선 촬영장치에 따르면, 엑스선제너레이터(3)에서 엑스선관(1)에 전력을 공급(도면부호 5)한 후, 피검체에게 엑스선을 조사(도면부호 6)하고, 피검체를 투과한 엑스선에 의해 엑스선검출기(2)에서 생성된 디지털 영상데이터를 컴퓨터(4)로 전송하여 연산처리토록 하였다.Therefore, according to the conventional digital X-ray imaging apparatus configured as described above, the X-ray generator 3 supplies power to the X-ray tube 1 (reference numeral 5), and then irradiates the X-ray to the subject (reference numeral 6). Then, the digital image data generated by the X-ray detector 2 was transmitted to the computer 4 by X-rays transmitted through the subject to be processed.
물론, 이때의 통신은 유선방식에 따른 것으로서, 상기 엑스선검출기(2)는 보다 우수한 엑스선 영상을 얻기 위하여, 엑스선제너레이터(3)의 준비신호와 조사신호 등을 요구하거나, 명령을 하도록 구성되었다.Of course, the communication at this time is a wired method, and the X-ray detector 2 is configured to request or command a preparation signal and an irradiation signal of the X-ray generator 3 in order to obtain a better X-ray image.
즉, 엑스선제너레이터(3), 엑스선검출기(2) 및 컴퓨터(4)간에는 유선으로 통신하도록 구성되어 있었다.That is, the X-ray generator 3, the X-ray detector 2, and the computer 4 were configured to communicate by wire.
그러나, 종래의 디지털 엑스선 촬영장치에 있어서는, 피검체인 환자의 촬영부위에 따라서는 상기 엑스선검출기(2)를 이동시켜야하는 경우가 발생되는데, 환자의 복부를 촬영하는 등의 특별한 상황에서는, 환자는 테이블(도시하지 않음) 위에 눕히고, 엑스선검출기(2)는 상기 테이블 아래에 배치시켜야 하며, 가슴촬영을 위해서는 버키스탠드(도시하지 않음)로 엑스선검출기(2)를 이동배치시켜야 했다.However, in the conventional digital X-ray imaging apparatus, there is a case where the X-ray detector 2 needs to be moved depending on the photographing portion of the patient, which is a subject. Lying on (not shown), the X-ray detector 2 had to be placed under the table, and the X-ray detector 2 had to be moved to a bucky stand (not shown) for chest imaging.
따라서, 상기 엑스선검출기(2)가 엑스선제너레이터(3) 및 컴퓨터(4)와 통신할 수 있도록 하는 다수의 신호선이 바닥면에 어지럽게 놓여 질뿐만 아니라, 상기 다수의 신호선이 그 위를 지나는 피검자에 의하여 밟히거나 훼손되기도 하고, 다수의 신호선에 의하여 오히려 검사자 또는 피검자가 넘어지는 등의 문제점이 있었다.Therefore, a plurality of signal lines that allow the X-ray detector 2 to communicate with the X-ray generator 3 and the computer 4 are not only cluttered on the bottom surface, but also by the examinee through which the plurality of signal lines pass over them. There are problems such as being stepped on or damaged, the tester or the subject falls over by a plurality of signal lines.
그리고, 상기 디지털 엑스선 촬영장치를 병원에 설치하는 과정에서, 엑스선제너레이터(3)와 엑스선검출기(2) 간에 유선통신을 할 수 있도록 하는 다수의 신호선을 배치하고, 정리하는 과정에서 시간이 많이 소요될 뿐만 아니라, 이들 장치를 재배치 하거나, 이동하는 경우에도 번거로운 문제점이 발생하였다.In addition, in the process of installing the digital X-ray imaging apparatus in a hospital, it takes a lot of time in arranging and arranging a plurality of signal lines to enable wired communication between the X-ray generator 3 and the X-ray detector 2. In addition, troublesome problems arise when these devices are relocated or moved.
