     1. Field 
     One or more exemplary embodiments consistent with the present disclosure relate to a medical image managing method and apparatus, and more particularly, to a method and an apparatus that manage a medical image by transmitting, deleting, and recovering the medical image. 
     2. Description of the Related Art 
     A medical image is captured by a medical photographing apparatus such as a magnetic resonance imaging (MRI) apparatus, a computed tomography (CT) apparatus, a position emission tomography (PET) apparatus, or an X-ray apparatus, and may be stored in a storage unit of a central control apparatus. A user may check the medical image stored in the storage unit of the central control apparatus, and use the medical image for a diagnosis of a patient. However, the storage unit of the central control apparatus has a limited storage capacity, and thus, cannot store all medical images captured by the medical image photographing apparatus. In the related art, in order to overcome the limited storage capacity of the storage unit, a user makes backup copies of the medical images stored in the storage unit to respectively store the backup copies in a plurality of external storage devices. However, when the user intends to check a desired medical image deleted from the storage unit of the central control apparatus, the user may not know which of the external storage devices has been used to store a backup copy of the desired medical image, and due to this uncertainty, diagnosis efficiency of a patient is reduced.

       FIG. 1  is a diagram illustrating a medical image managing apparatus  100  and a plurality of external storage devices  110 ,  120 ,  130  and  140  according to an exemplary embodiment. 
     Referring to  FIG. 1 , the medical image managing apparatus  100  may be connected to the plurality of external storage devices  110 ,  120 ,  130  and  140 . The medical image managing apparatus  100  according to an exemplary embodiment may include a central control device connected to a medical image photographing apparatus. 
     The medical image managing apparatus  100  may transmit a medical image stored therein to the plurality of external storage devices  110 ,  120 ,  130  and  140 . 
     The plurality of external storage devices  110 ,  120 ,  130  and  140  may respectively include a picture archiving and communication system (PACS) server  110 , a review workstation  120 , a compact disk (CD)/digital versatile disk (DVD)/blue ray disk (BD)  130 , and a universal serial bus (USB)  140 , but are not limited thereto. 
     A storage space of the medical image managing apparatus  100  is limited, and thus, has a limited capacity to store all medical images that are continuously acquired. For this reason, a user may be required to store backup copies of the medical images in the plurality of external storage devices  110 ,  120 ,  130  and  140  by transmitting the medical images to the plurality of external storage devices  110 ,  120 ,  130  and  140 .

     Therefore, when a user desires to recover a medical image deleted from the medical image managing apparatus  100 , the medical image managing apparatus  100  may easily recover the deleted medical image from the first external storage device on the basis of the mapping information. 
       FIG. 2  is a flowchart of a medical image managing method according to an exemplary embodiment. 
     In operation  200 , a medical image managing apparatus may transmit a medical image stored therein to a first external storage device selected from among a plurality of external storage devices by a user. 
     The medical image managing apparatus may select at least one or more medical images from among a plurality of medical images stored therein according to user input, and may transmit the selected medical image to the first external storage device. 
     According to an exemplary embodiment, the first external storage device may be an external storage device which is selected by the user from among the plurality of external storage devices connected to the medical image managing apparatus. It is understood, however, that the first external storage device is not required to be selected by the user, and may be automatically selected according to other exemplary embodiments. 
     In operation  210 , the medical image managing apparatus may store mapping information in which information about the first external storage device is mapped to information about the medical image. 
     The information about the medical image may be used by the user to identify and classify a type of the transmitted medical image. 
     The information about the first external storage device is information for easily identifying an external storage device to which the medical image is transmitted, by identifying a type of the external storage device and a transmitted date. 
     The mapping information is information which is stored and which maps the medical image selected by the user with the first external storage device receiving the medical image so as to easily determine which of the plurality of external storage devices stores the medical image. 
     In operation  220 , a deletion condition of a medical image stored in the medical image managing apparatus may be set based on user input. 
     The medical image managing apparatus may delete at least one of a plurality of medical images transmitted from the medical image managing apparatus to the first external storage device. The medical image managing apparatus may delete the at least one medical image based on various types of deletion conditions according to the type of the first external storage device. 
     According to an exemplary embodiment, the deletion condition may be set based on at least one of a residual capacity of a storage unit, whether there is a backup copy of a medical image, a time that elapses after the medical image is stored in the storage unit, and a frequency of use of the medical image. For example, according to an exemplary embodiment, the deleting condition may include a deletion condition to delete the medical image when the residual capacity of the storage unit is 10% or less, a deleting condition to delete the medical image when there is a backup copy of a medical image, a deleting condition to delete the medical image when three months elapses after the medical image is stored in the storage unit, and a deleting condition to delete the medical image when the number of times the user uses the medical image for treating a patient or for uses the medical image for other purpose is two times or less. 
     In operation  230 , the medical image managing apparatus may delete the medical image on the basis of the set deleting condition. 
     The medical image managing apparatus may delete a medical image, corresponding to the set deleting condition, from among all of the medical images stored therein. Also, the medical image managing apparatus may delete a medical image, corresponding to the set deleting condition, among arbitrary medical images which are selected from among the stored medical images by the user. 
       FIG. 3  is a flowchart of a medical image managing method according to another exemplary embodiment. 
     In operation  300 , a medical image managing apparatus may transmit a medical image to a first external storage device which is selected from among a plurality of external storage devices. 
     In operation  310 , the medical image managing apparatus may add an indicator, indicating whether to enable the medical image to be deleted, into information about the medical image, and display the indicator. 
     Although the medical image transmitted to the first external storage device may be deleted from the medical image managing apparatus, the deleted medical image may be recovered by restoring a backup copy of the medical image. However, when a medical image which is not transmitted to the first external storage device is deleted, the deleted medical image cannot be recovered. 
     In order to overcome such a limitation, the medical image managing apparatus according to an exemplary embodiment may add the indicator, indicating whether to enable the medical image to be deleted, into the information about the medical image so as to enable only medical images which are transmitted to the first external storage device to be deleted later. 
     In operation  320 , the medical image managing apparatus may store mapping information in which information about the first external storage device is mapped to the information about the medical image. 
     In operation  330 , a deleting condition of a medical image stored in the medical image managing apparatus may be set based on user input. 
     According to an exemplary embodiment, examples of the deleting condition may include a deleting condition that deletes medical images in a descending order of acquisition timings of the medical images, a deleting condition that deletes medical images in a first-in, first-out order from the first-acquired medical image (a first-in, first-out (FIFO) deleting condition), and a deleting condition that deletes a least recently used medical image (a least recently used (LRU) deleting condition). 
     The deleting condition may be set based on various criteria, including for example, at least one of a residual capacity of a storage unit, whether there is a backup copy of a medical image, a time that elapses after the medical image is stored in the storage unit, and a frequency of use of the medical image. 
     In operation  340 , the medical image managing apparatus may delete a medical image on the basis of the set deleting condition. 
     When user inputs instructions to delete a medical image after the deleting condition is set, the medical image managing apparatus may delete medical images stored therein on the basis of the deleting condition. 
     In operation  350 , the medical image managing apparatus may add an indicator, indicating whether to enable the deleted medical image to be recovered, into information about the deleted medical image. 
     When a backup copy of a medical image to be used to recover the medical image is stored in the first external storage device and the medical image managing apparatus is connected to the first external storage device, the medical image managing apparatus may recover the deleted medical image. 
     When the medical image managing apparatus is not connected to the first external storage device, the medical image managing apparatus cannot receive the medical image stored in the first external storage device, and thus, the deleted medical image cannot be recovered. Also, when a backup copy of a medical image to be used to recover the medical image is not stored in the first external storage device (for example, when a backup file is deleted from the first external storage device, or when the medical image is not transmitted to the first external storage device), the medical image to be transmitted to the medical image managing apparatus is not stored in the first external storage device, and thus, the medical image managing apparatus cannot recover the deleted medical image. 
     In operation  360 , the medical image managing apparatus may determine the first external storage device among the plurality of external storage devices on the basis of the mapping information according to the user&#39;s recovery input. 
     The medical image managing apparatus may determine the first external storage device among the plurality of external storage devices on the basis of the mapping information according to the user&#39;s recovery input for the deleted medical image. The user may obtain information of each medical image and information, mapped to the information of each medical image, of the first external storage device by using the mapping information which is stored in operation  320 . 
     When the user selects a medical image to be recovered on the basis of the mapping information, the user may determine the first external storage device recorded in the mapping information. 
     In operation  370 , the medical image managing apparatus may receive the deleted medical image from the first external storage device. 
     The medical image managing apparatus may receive a selected medical image from the first external storage device according to the user&#39;s recovery input. 
     The first external storage device is a storage device which stores the medical image, and the user may determine each of the first external storage devices respectively mapped to each medical image on the basis of information recorded in the mapping information. 
     When the user selects a medical image and inputs a recovery input, the medical image managing apparatus may receive the medical image from the first external storage device. 
       FIG. 4  is a diagram illustrating medical image information and device information according to an exemplary embodiment. 
     Referring to  FIG. 4 , according to an exemplary embodiment, a medical image is transmitted from a medical image managing apparatus to a first external storage device, and then the medical image managing apparatus stores an image information table  400  that shows information  410  about each medical image and information  420  about the first external storage device receiving the medical image. 
     The information  410  about each medical image may include a unique image identifier (UID), access information (Access Info) about the first external storage device, and a date at which the medical image was transmitted from the medical image managing apparatus to the first external storage device. 
     The image UID is an identifier (ID) for identifying medical images. 
     The access information (Access Info) about the first external storage device is used when a connection between the medical image managing apparatus and the first external storage device is needed (for example, when recovering the medical image). The access information (Access Info) about the first external storage device may selectively include content to record according to the user&#39;s preferences. For example, the access information (Access Info) about the first external storage device may include a network Internet protocol (IP) address (e.g., when the first external storage device is connected to the medical image managing apparatus over the Internet), a port number, an application entity title, external hard disk connection information, and a CD label. 
     An indicator, which enables a medical image (e.g., a medical image transmitted from the medical image managing apparatus to the first external storage device) to be deleted later, may be added into information about the medical image. 
       FIG. 5  is a diagram for describing a method of setting a deleting condition of a medical image according to an exemplary embodiment. 
     Referring to  FIG. 5 , a user may input a deletion command (for example, a cleanup command) for arranging a storage space of a medical image managing apparatus, and then may set a deleting condition in a deleting condition setting table  500  in which a deleting condition of a medical image is set by the medical image managing apparatus. 
     According to an exemplary embodiment, a medical image, which does not have an indicator to enable the medical image to be deleted, among pieces of information about medical images stored in the medical image managing apparatus, may not be deleted even when the deletion command is input. 
     The deleting condition setting table  500  may include an automatic deletion setting  510 , which sets types of images to be automatically deleted, and a deletion time  520  that indicates a deleting condition. 
     According to an exemplary embodiment, the automatic deletion setting  510  and the deletion time  520  may show that different deleting conditions are set according to devices which are used. For example, a setting may be made in which a medical image transmitted to a PACS server may be immediately deleted, a medical image copied to a recording medium may be deleted when at least 80% of a corresponding disk is used, a medical image transmitted to a workstation may be deleted when the medical image is least used among a plurality of medical images, a medical image of which a backup copy is not generated may be prohibited from being deleted, and a medical image copied to a mobile storage device may be deleted in an order starting with a first-transmitted medical image. 
     In addition, a deleting condition may be set according to the user&#39;s preferences, and for example, various settings may be set based on a type of the first external storage device. As examples of the various settings, medical images may be deleted in an order starting with the most recently captured medical image, the medical images may be deleted at random, the medical images may be deleted when a predetermined time elapses after transmission, the medical images may be deleted when at least 70% of a disk is used, the medical images may be deleted in an order starting with the most-used medical image, and the medical images may be deleted in an order starting with a first-transmitted medical image among a plurality of medical images. 
     When a setting of the deleting condition is ended, the user may start to delete medical images stored in the medical image managing apparatus by using a delete button, an execute short key, or any other input technique known to those skilled in the art. 
       FIG. 6  is a diagram for describing information about backup of medical images according to an exemplary embodiment. 
     Referring to  FIG. 6 , a medical image backup information list  600  indicating whether to enable a deleted medical image to be recovered may include a selection presence item  610  indicating whether a medical image for a backup is selected, a patient ID item  620 , an image ID item  630 , a device information item  640  indicating information of the first external storage device storing a backup copy, an examination kind ID (exam ID) item  650 , a photographing part ID (series ID) item  660 , a connection presence item  670  indicating whether to enable the medical image managing apparatus to be connected to the first external storage device, a backup presence item  680  indicating whether a medical image has been transmitted from the medical image managing apparatus to the first external storage device, and mapping information  690 . 
     When a backup copy is not generated by transmitting a medical image from the medical image managing apparatus to the first external storage device, a user will be unable to recover the medical image, and thus, a user may check the presence of a backup through the backup presence item  680  of the medical image backup information list  600 . 
     The user may determine, through the connection presence item  670 , whether to enable the medical image managing apparatus to be connected to the first external storage device.
