A database 8 for storing original image files and dichromic image files;

An operation unit for adjusting the high voltage generating apparatus 2 to set irradiation conditions, processing the image obtained by the detector 5 so as to be displayed on the screen, and transmitting the stored image to the medical image storage and delivery system 9 (6);

The operation unit 6 is monitored to determine whether the X-ray is irradiated. When the X-ray is irradiated, the dose value is requested and stored in the dosimeter. When a predetermined file including the patient information is found in the operation unit 6, And a dose information interlocking unit 7 for acquiring patient information and storing it in the database 8 together with the dose value.

The dose information interlocking unit (7)

A communication unit 100 for communicating with the dosimeter;

A dose data storage unit 110 for storing a dose value;

A patient information acquiring unit 120 for acquiring patient information;

The operation unit 6 is monitored to determine whether the X-ray is irradiated. When the X-ray is irradiated, the dose value is requested to the dosimeter through the communication unit 100, and the operation unit includes the patient information And a file monitoring unit 130 for acquiring patient information through the patient information obtaining unit 120 and storing the patient information together with the dose value in the database 8 if a dicom file is found.

The file monitoring unit 130 obtains the patient information from the dichromic image file header using the patient information obtaining unit 120 when the dichromic image file 50 is found and stores it in the dose data storage unit 110 And irradiates the database 8 with the dose value.

The file monitoring unit 130 recognizes whether an X-ray is irradiated in the X-ray tube apparatus by confirming whether an original image file or a processed image 20 is generated.

Such a digital radiography system can set the irradiation conditions by adjusting the high voltage generator 2 with the operation unit 6 installed in the work station 1 or process the image obtained by the detector 5 and display it on the screen . Then, the stored image is transmitted to the medical image storing and transmitting system 9.

In the embodiment of the present invention, the workstation is provided with a dose information interlocking section 7 separately from the operation section 6, and the dose value measured by the dosimeter 4 and the patient information are interlocked and stored together in the database 8, .

In the operation unit 6, the image obtained from the detector 5 is first processed by the image obtaining unit 10 and displayed on the screen, and the original image file or the processed image is stored (step 20). The stored image is processed again by the image processing unit 30 or is stored as an image file of the DICOM 50 through the image storage unit 40 using the processed image. This dichromic image file contains information about the photographed patient in its header.

The image display unit 60 displays an image that is being photographed or has been processed on the screen and the stored diCom image file 50 is transmitted to the medical image storage and delivery system 9 through the image transfer unit 70.

Here, in the embodiment of the present invention, whether the file monitoring unit 130 of the dose information interlocking unit 7 continuously generates the original image file or the processed image 20 stored in the image obtaining unit from the start to the end of the program .

Accordingly, the file monitoring unit 130 recognizes that the X-ray is irradiated from the X-ray tube apparatus and requests the measured dose value to the dosimeter 4 through the communication unit 100.

When the dose value is received, the dose monitoring unit 130 stores the dose value in the dose data storage unit 110 through the communication unit 100. When the diocom image file 50 is found, ) To acquire patient information from the dichromic image file header and transmit the dose information to the internal or external database 8 together with the dose value stored in the dose data storage unit 110 to manage the patient exposure dose.

4 is a flowchart illustrating an operation of the dose recording apparatus of the digital radiography system according to the embodiment of the present invention.

Referring to FIG. 4, the file monitoring unit 130 is driven in step S201 and the original image file 20 and the diCom image file 50 newly generated until the program ends (S214) are continuously monitored.

The file monitoring unit 130 monitors whether or not the original image file is generated in S202, and when the original image file is found (S203), the file monitoring unit 130 determines that the X-ray is irradiated and requests the newly measured value to the dosimeter 4 (S204) . However, steps S202, S203, and S204 may be omitted if the dosimeter does not request a value but automatically sends a value when the X-ray is irradiated.

The requested dose value arrives through the communication unit 100 and is stored in the dose data storage unit 110 (S205). After storing the dose value, the file monitoring unit 130 monitors whether the original image file 20 and the dichromic image file 50 are generated (S206).

If the dichromic image file is found first, basic information on the patient is acquired using the patient information acquiring unit 120, and the dose values stored in the storage unit 110 are transmitted to the database 8 together. However, if the original image file 20 is found first, the value of the dose data storage unit 110 is updated.

Here, in addition to the method of storing in the database 8, a method of directly inserting the dose value into the header of the dichromic image file 50 can be taken (S208). In this case, the dichromic image file 50 can be transferred to the medical image storage and delivery system 9 through the video transmission unit 70 of the operation unit 6, which is the operating software, to manage the dose.

However, this method is difficult to realize by the diacom rule that the diCom image file generated by the digital radiography apparatus can not be arbitrarily changed.

Therefore, as a method for avoiding this, a method of making a copy of the diCom image file 50 and inserting a dose value into the header can be taken (S212). In this case, it may be transmitted to the medical image storage and delivery system 9 using software separate from the operation software 6.

All the above processes are repeated until the program ends (S214).

In the embodiment of the present invention, when the dosimeter 4 is separately installed in the digital radiography system, the dose management can be performed automatically.

Further, in the embodiment of the present invention, the same accuracy as the dose value obtained by actual measurement can be obtained.

In addition, the embodiment of the present invention can be implemented with a small cost.

In addition, the embodiment of the present invention adopts a method of monitoring a newly generated file, so that the patient information and the measured dose value can be interlocked with each other while minimizing the installation of the auxiliary device.

The embodiments of the present invention described above are not only implemented by the apparatus and method but may be implemented through a program for realizing the function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded, The embodiments can be easily implemented by those skilled in the art from the description of the embodiments described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It belongs to the scope of right.
