2 is a diagram illustrating an apparatus 100 for calculating a radiation dose according to an embodiment of the present invention.

2, the radiation dose calculation apparatus 100 according to the present embodiment includes a radiation imaging apparatus 300 such as an x-ray, a computed tomography (CT), and a positron emission tomography (PET) (DICOM) file from a radiographic imaging apparatus 300, and is configured to receive, from the DICOM file, radiation for each radiographic apparatus .

The radiation dose calculation apparatus 100 according to the present embodiment does not calculate the radiation dose from the DICOM file stored in the PACS 200 but the DICOM file from the radiography apparatus 300 before the DICOM file is stored in the PACS 200. [ And a radiation dose for each radiographic apparatus is calculated from the received radiation dose. Therefore, the radiation dose calculation apparatus 100 according to the present embodiment can easily calculate the radiation dose information regardless of the type of the PACS and the access authority, and can also calculate the radiation dose for each of the radiation imaging apparatuses 300 Can be measured.

The radiation dose calculation apparatus 100 according to the present embodiment includes a DICOM reception unit 110 for receiving a DICOM file including a DICOM header from the radiation imaging apparatus 300, An apparatus extracting unit 120 for extracting identification information on the apparatus, a radiation dose calculation unit 130 for calculating a radiation dose for each radiation imaging apparatus 300 using radiation information and identification information, A DICOM transmission unit 140 for transmitting the DICOM file to the PACS 200, and a dose storage unit 150 for storing the radiation dose information for each equipment.

The conventional radiation dose calculation device can not calculate the radiation dose for each of the radiation imaging apparatuses 300 but has a limitation in that it can only measure the radiation dose and the like for the entire hospital. As a result, it is impossible to determine the degree of radiation dose to be used in a certain hospital when a plurality of hospitals and various kinds of radiation equipments are provided in one hospital.

Further, the conventional radiation dose calculating apparatus has a problem that the radiation dose can be measured in duplicate. For example, when a radiological image taken by a hospital is used without a separate re-imaging in the hospital B, the conventional radiation dose calculation device is considered to have used the relevant radiation dose for the patient A and the hospital B Radiation dose is identified as duplication. Such a problem of duplicate estimation can occur even when the radiation image taken at another point in the same hospital is used as it is.

The radiation dose calculation device 100 according to the present embodiment is characterized by measuring the radiation dose for each of the radiation imaging devices 300. [ For example, when one hospital is provided with n x-ray systems (x1, x2 to xn) and m CT devices (c1, c2 to cm), the radiation dose calculation apparatus 100 according to the present embodiment x1, x2 to xn, and the radiation dose information for each of c1, c2 to cm are individually measured. As a result, it is possible not only to solve the problem that the radiation dose is calculated in duplicate, but also to manage the radiation dose efficiently.

The DICOM receiving unit 110 receives the DICOM file from each radiographic apparatus 300. The DICOM file contains the DICOM header. The DICOM header contains image information, radiographic examination information, and patient information. Here, the image information may include a voltage amount (KVP) of the X-ray generator, a tube current, and a source image receptor distance (SID) value when capturing an image using the radiographic apparatus 300 have.

In addition, the tags of the DICOM file include hospital information (InstitutionName) and equipment unique information (StationName). The identification information can be grasped by the radiographic apparatus 300 using the hospital information and the apparatus-specific information.

The information extracting unit 120 extracts information for calculating a radiation dose and identification information of the radiography apparatus 300 from the DICOM file received by the DICOM receiving unit 110. [

The information for calculating the radiation dose may correspond to a voltage amount (KVP), an x-ray tube current amount and a source image receptor distance (SID) included in the header of the DICOM file. It is not limited. Further, the information for calculating the radiation dose may further include additional information such as the name of the patient, the sex, the imaging site, the date and time of the examination, and the purpose of the examination.

The identification information of the radiographic apparatus 300 may correspond to a DICOM tag value such as hospital information (InstitutionName) and equipment unique information (StationName). The hospital information may include the name of each hospital, information for the head office, or branch information. Also, the equipment-specific information may include the type, location, and serial number of the equipment.

The radiation dose calculation unit 130 for each equipment measures the radiation dose for each of the radiation imaging apparatuses 300 using the information for calculating the radiation dose and the identification information of the radiation imaging apparatus 300. [

The radiation dose calculation unit 130 may calculate the radiation dose used to photograph the corresponding image in the equipment using the information for calculating the radiation dose. In order to calculate the radiation dose, the radiation dose calculation unit 130 of the equipment calculates the effective surface dose by using the voltage (kVp) of the x-ray generator and the amount of the x-ray tube current (mAs) Can be obtained.

The radiation dose calculation unit 130 may use the additional information extracted by the information extraction unit 120 to obtain an accurate effective dose. The additional information may include, for example, a patient's sex, age, And the type of equipment.

The radiation dose calculation unit 130 matches the identification information of the radiation imaging apparatus 300 with the calculated radiation dose to determine how much radiation dose is used in one device for one medical image. The identification information of the radiographic apparatus 300 may be a DICOM file, but not limited to, hospital information (InstitutionName) and equipment-specific information (StationName) included in the tag.

The radiation dose used by the equipment-specific radiation dose calculator 130 as well as the name of the hospital where the radiographic apparatus 300 is located, (Eg, x-ray, CT, or PET), the location of the equipment in the hospital (eg, first thoracic surgery room), and the serial number of the equipment (eg, A hospital neurosurgery CT).

The radiation dose calculation unit 130 may calculate the radiation dose for each of the radiation imaging apparatuses 300 and store the radiation dose in the radiation dose storage unit 150 for each equipment. The device-specific dose storage unit 150 may store information on the amount of radiation used in each device and provide the information to the user. Therefore, since the radiation dose calculation apparatus 100 according to the present embodiment can manage the radiation dose by equipment, it is possible not only to facilitate the reduction of the dose but also to solve the problem of overlapping the radiation dose.

The individual dose storage unit 150 can further divide and store information on the radiation dose and provide it to the user. For example, the dose storage unit 150 for each equipment can store radiation dose information used for a day, month, or year in one device and graphically provide the radiation dose information to the user. In addition, the dose storage unit 150 for each equipment can provide information on the radiation dose of the same group of radiography apparatuses 300 used in one hospital. For example, Ray apparatus, CT, PET, and the like can be summed and supplied to the user.

The DICOM transmission unit 140 transmits the DICOM file received from the radiological apparatus 300 to the PACS 200. The PACS 200 receives the DICOM file for the medical image and digitizes the DICOM file through a CR (Computed Radiography) or the like, stores the DICOM file on a storage medium such as a hard disk, and transmits the medical image stored in the workstation,
