Referring to FIG. 1 , a dental image processing apparatus 1 obtains a dental image through dental software and provides various image analysis and simulation functions. To this end, the dental image processing apparatus 1 may include an electronic device capable of executing dental software, and a server communicating with the electronic device through a network. Electronic devices include computers, notebook computers, laptop computers, tablet PCs, smart phones, mobile phones, personal media players (PMPs), personal digital assistants (PDAs), and the like.

The dental software according to an embodiment may be a dental practice management system (PMS) software (hereinafter, referred to as 'PMS software'). PMS software is a one-stop digital dentistry that organically links the entire process from patient visit/reception to diagnosis and data acquisition, diagnosis and treatment planning, treatment, and post-treatment management based on PMS, that is, a practical management system. Tree (One Stop Digital Dentistry) provides solutions and services.

The PMS software may be software that integrates and manages tasks. For example, it is possible to organically link with various software such as insurance claim software, image viewer software, surgical guide production software, orthodontic diagnosis software, CAD software, and dental patient consultation software within one PMS software screen. Accordingly, wide compatibility can be provided. In particular, the present invention relates to a technology for interworking with image viewer software. CT Viewer, one of the image viewer software, can provide various image analysis and simulation functions by reconstructing tomographic images acquired through CT scans into 3D images. It helps to analyze images quickly and conveniently by providing screen composition and tools specialized for the user's purpose.

Hereinafter, the configuration of the dental image processing apparatus 1 will be described in detail later.

Referring to FIG. 1 , a dental image processing apparatus 1 according to an embodiment includes a data acquisition unit 10 , a storage unit 12 , a control unit 14 , an input unit 16 , and an output unit 18 . .

The data acquisition unit 10 acquires image data of the patient. In this case, image data may be acquired through imaging, and imaging includes CT, sensor, panoramic imaging, and the like. For example, the data acquisition unit 10 acquires CT data from teeth including a damaged target tooth of a patient through CT imaging. The image data may be in a two-dimensional or three-dimensional form. The data acquisition unit 10 may execute image data in software or load image data stored in a web page or a server.

For CT data, computed tomography (CT) may be used to generate tomographic images of the patient's head, and each tomographic image may be combined to obtain a 3D image. The acquired CT data may be stored in the storage unit 12 . CT data are images obtained by imaging the maxillary teeth from below the maxillary teeth with the patient open, images obtained by imaging the mandibular teeth above the mandibular teeth with the mouth open, images obtained by imaging local areas with the mouth closed, and oral radiographs. including photos, etc.

The control unit 14 controls each component through control by computer software. The control unit 14 manages screen information displayed on the screen through the output unit 18 , and analyzes and simulates two-dimensional and three-dimensional structures for image data.

The controller 14 according to an embodiment provides a function of detecting a lesion in a dental image, and specifies a region of interest (ROI) in which a lesion is to be observed, and preferentially detects a lesion in the specified region of interest. Note that the term 'preferentially' is used to mean that the time required for lesion detection is reduced and the detection accuracy is increased by preferentially detecting the lesion in the region of interest rather than detecting the lesion only in the region of interest.

The controller 14 may select a region of interest for observing a lesion through a user designation of a patient's lesion list (hereinafter, referred to as a 'PI list') or a dental image. The PI list may be automatically generated by the control unit 14 analyzing the dental image acquired through the data acquisition unit 10, or may be manually generated through a user input.

In the method of selecting a lesion region of interest using the PI list, the PI list in which the lesion details are recorded together with the tooth number is displayed on the screen through the output unit 18, and a user manipulation signal is received through the input unit 16 on the PI list. It is a method of receiving the input and selecting the lesion details or the tooth number for which the user wants to see the lesion. In this case, the controller 14 may determine the region of interest based on the identified tooth number by checking the tooth number or the selected tooth number in the selected lesion history. When the PI list is automatically created, the tooth number and lesion details are automatically created, and when the PI list is manually created, the user inputs and writes the lesion details together with the tooth number. The lesion can be detected by specifying the corresponding tooth number.

The method of selecting a region of interest for a lesion through user designation in a dental image is to select a region of interest through an operation to select and input a predetermined tooth number or anatomical structure from a user through the input unit 16 in a dental image in which tooth segmentation is made. way to specify. In this case, the dental image may be a general panoramic image before CT scan or a panoramic image obtained after CT scan. For example, the user designates a region of interest by clicking on a portion where a lesion is to be observed in a general panoramic image or a panoramic image. In this case, the controller 14 may retrieve a CT image, search for a region corresponding to the region of interest in the general panoramic image or the panoramic image, and then detect a lesion in the searched region. In both the panoramic image and the panoramic image, the tooth number can be recognized because the teeth are divided.

The controller 14 according to an embodiment acquires a dental image of the patient through the first software and selects an ROI for observing a lesion, and selects the ROI selected from the second software linking the first software and the dental image. The lesion detection result can be displayed with the center. In this case, the first software may be PMS software, and the second software may be image viewer software. The image viewer software may be a CT viewer. To this end, the controller 14 calls the second software when the region of interest is selected through the first software. And the same region of interest as the region of interest selected by the first software on the called second software dental image (eg, continuous cross-sectional image centered on the lesion, automatically generated panoramic image, and automatically segmented 3D image) After searching for , a lesion may be preferentially detected in the searched ROI, and then the lesion detection result may be displayed on the screen through the output unit 18 .

The input unit 16 receives a user manipulation signal. For example, a user manipulation signal for designating a region of interest in which a lesion is to be observed is received. The output unit 18 displays the screen configuration information generated through the control unit 16 on the screen. For example, a lesion detected in a dental image may be displayed. The output unit 18 may display the lesion as a continuous cross-sectional image centered on the lesion, an automatically generated panoramic image, a 3D image in which anatomical structures are automatically divided, and the like through a CT viewer.

The storage unit 12 stores various data such as information necessary for performing the operation of the dental image processing apparatus 1 and information generated according to the operation. Image data of an individual patient is stored in the storage unit 12 according to an embodiment, and image data of a specific patient among all image data during a dental treatment simulation may be provided to the controller 14 according to a user's request.

Referring to FIG. 2 , after acquiring a dental image of the patient ( S21 ), the software generates a PI list of the patient from the acquired dental image ( S22 ). In this case, the software may automatically generate the patient's PI list by analyzing the acquired dental image, or may manually generate it through a user input. The patient's PI list includes treatment history, treatment history (including detected lesion history), and separated tooth number information. The software automatically performs automatic segmentation, lesion detection, and image generation from the acquired dental image, and provides the detected lesion history through the PI list, and displays the lesion in the form of a symbol through the automatically generated image. . Objects for automatic segmentation include lesions, teeth, and anatomical structures, and anatomical structures include nerves, maxillary sinuses, and maxillary sinuses.

Then, the software selects an ROI in which a lesion is to be observed through a user designation in the PI list or a dental image (S23), and detects the lesion in the selected ROI (S24).

In the region of interest selection step S23, the software may receive a user manipulation signal from the PI list in which the lesion details are recorded together with the tooth number, and the user may select the lesion details or tooth number for which the user wants to observe the lesion. In this case, the software may determine the region of interest based on the identified tooth number by checking the tooth number or the selected tooth number in the selected lesion history.

In the region of interest selection step ( S23 ), the software may select and input a predetermined tooth number or anatomical structure from the user in the dental image in which the tooth is segmented to designate the region of interest. The dental image may be a general panoramic image or a panoramic image in which teeth are segmented. Then, in the lesion detection step S24 , the software may search the ROI corresponding to the ROI selected on the general panoramic image or the panoramic image on the CT image and detect the lesion with respect to the found ROI.

On the other hand, the step of generating the patient's PI list (S22) is not essential, and the present invention provides the user with i) the PI list described in the description of the region of interest selection step (S23) to select the lesion through user designation in the PI list. Both the case of selecting the region of interest to be detected and the case of selecting the region of interest for detecting a lesion through user designation in the dental image by providing a dental image to the user are assumed. Through this, i) a PI list, ii) a dental image, or both i) a PI list and ii) a dental image may be provided to the user.

Then, the software displays the lesion detection result on the screen (S25). In the lesion detection result display step S25 , the software may display the lesion region including the detected lesion in at least one of a single cross-sectional image, a continuous cross-sectional image, a panoramic image, and a 3D image.

In the lesion detection result display step (S25), the software determines the axial direction of the image to display the lesion area by using the detected lesion information or tooth information corresponding to the detected lesion, and determines the lesion area based on the determined axial direction. can be displayed in the form of a single cross-sectional image or a continuous cross-sectional image. The information on the lesion may be a position or an angle of the lesion. The tooth information may be a tooth number of a tooth in which a lesion is detected. For example, the image axis direction may be determined through tooth number information received from the divided dental image (eg, panoramic image). As another example, a lesion may be detected based on a region of interest in a (CB)CT image, and an image axis direction may be determined using information on a tooth in which the lesion is detected.

The image axis direction includes an Arch Axis (AA, hereinafter referred to as 'AA') direction, a Buccal Axis (BA, hereinafter referred to as 'BA') direction, and a Mesial Axis (MA, hereinafter referred to as 'MA') direction. The cross section in the AA direction is a plane perpendicular to the tooth axis and can be called an axial cross section for the lesion area. The cross section in the MA direction is a plane perpendicular to the line consisting of the maximal ridge, and it can be called a Sagittal cross section for the lesion area. Also, these cross-sections may have a perpendicular relationship to each other.

Further, in the lesion detection result display step (S25), the software switches the axial direction of the image to display the lesion area based on the user's motion, and displays the lesion area in the form of a single cross-sectional image or a continuous cross-sectional image based on the switched axial direction. can be displayed as The user operation may be an operation of selecting a predetermined user interface from among user interfaces indicating different axial directions on the screen.

The software according to an embodiment performs the patient's dental image acquisition step (S21), the patient's PI list creation step (S22), and the ROI selection step (S23) through the first software, and the lesion detection step (S24) and The step of displaying the lesion detection result ( S25 ) may be performed through the second software. In this case, the first software and the second software link the dental image. The first software may be PMS software, and the second software may be image viewer software. The image viewer software may be a CT viewer.

When interworking between the PMS software and the CT viewer, in the region of interest selection step S23, the PMS software may designate the region of interest through the PI list or the region of interest by selecting the tooth number in the panoramic or panoramic image. When designating the region of interest, the PMS software calls the CT viewer. Then, in the lesion detection step S24, the CT viewer detects the lesion in the region of interest, and displays the lesion detection result detected in the lesion detection result display step S25 on the screen.

Hereinafter, a process for detecting a lesion in a region of interest through a PI list in the PMS software will be described with reference to FIGS. 3 to 8 .

After searching for a patient, a dental image is obtained by transmitting an image photographing order to request an image photographing (S32). In this case, a panoramic photographing, a sensor photographing, a CT photographing, etc. may be requested.

Then, the software creates a PI list (S34). In this case, the software may analyze the dental image to automatically generate the PI list, and the user may view the dental image or patient symptoms displayed on the screen and manually create the PI list through the user input. In the dental image, tooth segmentation (S33) is performed automatically.

Next, the user selects the lesion history or tooth number to be observed from the PI list (S35) to limit the region of interest including the tooth number and the periphery. When the user's ROI is limited, the PMS software calls the CT viewer (S36). The CT viewer searches for the same ROI on the CT image corresponding to the ROI selected in the PMS software (S37). Then, a lesion is detected in the searched region of interest and the result of the detection of the lesion is displayed on the screen (S38). In this case, the CT viewer may display the detected lesion as a single cross-sectional image, a continuous cross-sectional image, a panoramic image, a 3D image, or the like.
