Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention can be used for all types of medical X-ray apparatuses such as dental X-ray apparatuses and X-ray apparatuses used in internal medicine and surgery. More particularly, the present invention relates to an X-ray imaging control apparatus that automates troublesome operations such as setting of imaging conditions and prevents erroneous operations. 2. Description of the Related Art Conventionally, in a medical X-ray imaging apparatus, imaging conditions such as a tube voltage and a tube current have to be set for each subject such as a patient or for each imaging. Was. Further, for example, in a case where a dental X-ray imaging apparatus performs panoramic imaging of a tooth, the imaging is performed in accordance with a standard dental arch. However, in practice, there are few patients having a tooth shape that matches the standard dental arch, and it has been difficult to obtain an appropriate X-ray panoramic photograph. (Problems to be Solved by the Invention) In the conventional X-ray imaging apparatus as described above, operating conditions and the like must be set for each patient or each time of imaging, and the operation is troublesome and erroneous operation is required. There were drawbacks such as doing. The present invention has been made in order to solve such a conventional drawback, and in X-ray imaging, erroneous operations are eliminated and operations are facilitated by automating operations such as setting troublesome imaging conditions. It is intended to be accurate. (Means for Solving the Problems) The present invention achieves the above object, and comprises an X-ray imaging apparatus, a control circuit and a drive source for operating the apparatus, and an input / output interface unit. CPU
(Central processing unit) and a computer having a memory. The computer is controlled based on data in the memory. As a part of the memory, it is detachable from the X-ray imaging control device. An X-ray imaging control device is provided with a ROM (read only memory) card in which data on information for instructing a lock state and data on imaging conditions corresponding to each patient are stored. (Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram of an X-ray imaging control apparatus according to one embodiment of the present invention. In the figure, reference numeral 1 denotes an operating device, which comprises a keyboard, various operation switches, and the like. 2 is an input / output interface unit (I / O), 3 is a CPU (central processing unit), 4 is a ROM (read only memory) storing various programs and data, 5 is an address bus, 6 is a data bus , 7 are control buses, which constitute a main part of the computer. The control bus 7 informs the ROM 4, the input / output interface unit 2, and other memories of what the CPU 3 is currently doing and what state the CPU 3 is in. This is a transmission path for transmitting a control signal. Reference numeral 8 denotes a ROM (read only memory) card.
The OM card 8 is provided with a large number of terminals 9, which are connected to a connector provided on the X-ray imaging control device main body.
It is detachable from 10. 11 is a drive control circuit, 12 is a drive source such as a motor,
13 is an imaging condition control circuit, 14 is an X-ray imaging device, 15 is an imaging condition detector coupled to the X-ray imaging device 14 for detecting whether or not the device is operating according to set conditions. is there. Next, the operation will be described. The X-ray imaging control device enters a standby state by inserting the ROM card 8 into the connector 10 and is ready for use.
When the M card 8 is removed from the connector 10, the entire device is locked in an inoperative state. The ROM card 8 stores the above-described operation, that is, data relating to information for instructing the lock / unlock state of the imaging apparatus and data relating to imaging conditions corresponding to each patient. ing. For example, in the case of panoramic radiography in dentistry, data on the patient's gender, physique, film sensitivity, dental arch shape, etc., and data such as tube voltage, tube current and other radiographing conditions, etc. Data related to the operation of the apparatus and the like are stored in the ROM card 8. And such a ROM card prepares any combination of data to suit any patient,
Organize them so that they can be quickly removed at any time. In this way, the user can take out the ROM card 8 which is suitable for the patient, insert the terminal 9 into the connector 10, and then take any X-ray.
The radiography is performed automatically. That is, when the operating device 1 is operated in a state where the ROM card 8 is inserted into the connector 10, the data stored in the ROM card 8 is transferred to the drive control circuit 11 via the CPU 3.
And transmitted to the photographing condition control circuit 13. Thereafter, for example, in the case of a dental panoramic X-ray imaging apparatus, the drive source 12 moves the X-ray tube device, the film, and the like of the X-ray imaging apparatus 14 under the conditions based on the data of the ROM card. Further, in accordance with this movement, X-ray imaging is performed under imaging conditions determined by the data of the ROM card. In this case, it is detected by the imaging condition detector 15 whether or not the imaging was performed under the imaging conditions that match the data of the ROM card, and the data is transmitted to the CPU 3 via the input / output interface unit 2, and is always stored in the ROM card. Appropriate control is performed so that photographing is performed in accordance with stored data. When the photographing is completed, if the ROM card 8 is removed from the connector 9, the entire device is locked and does not operate. It should be noted that the present invention is not limited to the above embodiments, and can be used not only for dental X-ray imaging apparatuses such as panoramic type, cephalometric type, and dental type, but also widely for general medical X-ray apparatuses. It is. (Effects of the Invention) As described below, the present invention has the following effects. (1) The X-ray imaging technician who operates the X-ray imaging apparatus simply selects and removes a ROM card storing conditions suitable for the patient, and inserts the ROM card into the connector of the X-ray imaging control apparatus.
X-ray photography always suitable for the patient can be performed. Therefore, there is no risk of setting the imaging conditions incorrectly. For example, even when imaging the same patient every week, the reproducibility is extremely good. (2) Since the ROM card is thin and small, it requires less storage space and is easy to organize.
