As shown in FIG. 1, in the DICOM image and non-DICOM content matching and displaying method according to an embodiment of the present invention, a DICOM image already stored is selected. DICOM images are stored in the storage of a specific local PACS system in the case of a VNA system interworking with a local PACS system of this different model. DICOM images, which are expected to be read at each stage of storage, can be stored in high-speed access storage, while DICOM images, which are not expected to be read for a while, can only be stored at a large storage capacity.

Next, patient information, accession number, modality information, and body part information of the selected DICOM image are acquired. Here, the liquid session number corresponds to, for example, a test number to be examined for diagnosis of a specific patient and is shot at one time during X-ray, CT, or MRI, and is read as one study in the local PACS system It is a unique number for a bundle of images to be stored. Also, the modality information is an example of the unique identification number of the corresponding equipment such as X-ray, CT, or MRI. The body part information may be the body part of the photographed image, such as the brain or lung.

Next, an uploader is opened to upload non-DICOM content related to the DICOM image. There will be a user interface for the uploader. At the interface of the uploader, the patient information, the session number, the modality information, and the body part of the non-DICOM content are written, and the non-DICOM content is uploaded through the interface of the uploader.

At this time, when the patient information, the liquid session number, the modality information and the body part of the non-DICOM contents are written in the interface of the uploader, the patient information, the liquid session number, the modality information, It is possible to eliminate the inconvenience that the related information should be written when the user uploads that the body part is automatically written on the basis of the body part. Of course, it is also possible to modify and input the information that is automatically written or autocompleted.

Here, the Non-DICOM content is any one of a medical file (JPEG, etc.), a picture file, a report, a music file (read voice), a moving picture file, a Korean language file, a PPT file, and a word file Or more.

2 is a flowchart illustrating display steps in a DICOM image and non-DICOM content matching and displaying method according to the present invention.

2, selecting to view the DICOM image; Searching for Non-DICOM contents having the same information on the basis of the patient information, the liquid session number, the modality information and the body part of the DIOCM image; And displaying the retrieved non-DICOM contents together with the DICOM image on the screen.

When there are a plurality of non-DICOM contents searched, a list of the plurality of non-DICOM contents is displayed, and the non-DICOM contents selected according to the user's selection are displayed together with the DICOM image on the screen, If there are a plurality of DICOM contents, a plurality of non-DICOM contents are selected based on the number of times of the user's existing selection (i.e., the number of times the corresponding non-DICOM contents are selected or viewed) When the list is displayed, the non-DICOM contents selected in accordance with the user's selection may be displayed in the priority order and displayed together with the DICOM image on the screen. That is, the longer the viewing time or the longer the viewing time, the more the non-DICOM contents can be displayed as the priority, that is, the top or the largest icon, or the largest window.

3 is a diagram illustrating a left image in which a character is broken when a conventional method is adopted and a right image showing a case where a document captured image is corrected in a manner according to the present invention. FIG. 4 is a flowchart illustrating steps of an image correction method for a document captured image used in a DICOM image and non-DICOM content matching and displaying method according to the present invention.

As described above, in the field of medical image systems, a medical image system, which was conventionally operated as an individual local PACS system, has recently been developed as a VNA system that can be integrated and operated without problems between different types of local PACS systems. ), That is, research and development on non-DICOM contents, especially non-DICOM images, rather than DICOM images, are being actively carried out in related fields.

In the case of a non-DICOM image, which is currently actively used, when an image captured by a conventional document is subjected to image processing through linear interpolation, the brightness of the image pixel is reduced due to the limitation of the linear interpolation algorithm Will be different. This causes the characters displayed in the image to change to such an extent that they can not be recognized. Furthermore, since the medical image PACS expresses the most visible value of the original image through WWL (Window Width Level), it can not take into consideration the characters in the image, and thus the characters in the image are not displayed well.

FIG. 3 shows a left-side image in which a character is broken when a conventional method is adopted, and a right-side image showing a case in which a document-captured image is corrected in a method according to the present invention. As shown in FIG. 3, You can see the appearance of broken.

As shown in FIG. 3, an image correction method of a document capture image used in a DICOM image and non-DICOM content matching and displaying method according to an embodiment of the present invention receives an input of an image first. As will be described later, the object of the present invention is not to output the image input from the local PACS system as it is, but to display the original image on the client application such as a mobile terminal on a VNA system viewed by a medical staff or the like It is a technology applied when it can not be used as it is. In addition, it is a technology that can be performed individually or in parallel in a VNA system for interworking with a heterogeneous local PACS, in an image storage storage, a VNA server, or an application of a client.

Next, the image histogram analyzing unit analyzes the image histogram of the input image, and calculates the number of brightness types of the image. That is, if the image histogram of the input image is analyzed, if the brightness of the image is 0 to 255, for example, 0 to 255, 245, 247, and 255, the number of brightness types of the image is 4.

Next, a predetermined brightness number number reference value set according to the image bit value of the image is set. For example, the reference value of the predetermined number of brightness types is set differently according to the 8-bit, 12-bit, and 16-bit image bit values.

Next, the number of brightness types of the image and the predetermined number of brightness type number reference values are compared with each other. As a result of the comparison, if the number of brightness classes of the image is smaller than the predetermined brightness class number reference value or the number of brightness classes of the image is less than or equal to the predetermined brightness class number reference value, the document type image analysis and judgment unit judges or regards the corresponding image as a document capture image do.

If the image is judged to be a document captured image, the optimal window width and level for the document captured image are calculated through the auto WWL (Auto WWL) calculation unit. The image is processed through the corrected window width and level value. When the WWL optimization value of the entire document capture image is found and displayed through the auto WWL, the character of the image can be displayed in an optimized form without a broken form as in the right image of FIG.

As a result of the comparison, if the number of brightness categories of the image is larger than the predetermined number of brightness category reference values or the number of brightness categories of the image is greater than or equal to the predetermined brightness category number reference value, the image is judged as an image other than the document, , The image is processed through the original WWL value of the image other than the document, and processed by a method such as linear interpolation.

And outputs an image or a document capture image other than the finally corrected document. The output image is a reduced or enlarged image of the input image, and it is matched with the DICOM image.

While the present invention has been described with reference to certain exemplary embodiments and drawings, it is to be understood that the invention is not to be limited to the details given herein, but the invention is not limited thereto. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims.
