Description

BACKGROUND ART Control System and Method for Photographing Apparatus Having Automatic Setting Function

The present invention relates to a control system and a control method of an image capturing apparatus having an automatic setting function of an image capturing position, and more particularly, to an image capturing apparatus having an automatic setting function of an image capturing position based on an image capturing position during a recent image of a patient. It relates to a control system and a control method.

In general, in dentistry, an X-ray apparatus capable of performing X-ray imaging in order to detect the state of teeth and alveolar bone for the purpose of treating teeth and various periodontal diseases or for orthodontic treatment of teeth is provided.

The dental X-ray imaging apparatus includes a computerized tomography (CT) X-ray imaging apparatus capable of photographing a three-dimensional stereoscopic image, and a panoramic X-ray imaging apparatus capable of photographing a two-dimensional plane.

A CT X-ray imaging device is an imaging device that shows a tomographic image of the body that cannot be represented by general imaging. It is a tomography device that collects and reconstructs absorption values for cross-sections of the human body and displays them as images.

In addition, the panoramic X-ray imaging device is a device that can take a panoramic picture so that the entire tooth condition and the temporomandibular joint can be seen at a glance by photographing the whole in the circumferential direction centering on the X-ray generator.

A CT X-ray imaging apparatus can acquire only a tomographic image, whereas a panoramic X-ray imaging apparatus can acquire only a panoramic image. Accordingly, recently, X-ray imaging apparatuses capable of acquiring both tomographic images and panoramic images have been developed.

In relation to this prior art, Patent Publication No. 10-2007-0017664 discloses a technology related to a panoramic and CT combined X-ray imaging apparatus.

In this panoramic and CT combined X-ray imaging device, the X-ray sensor unit and the X-ray light source unit are disposed on the rotating arm to face each other, and the X-ray light source disposed on the rotating arm to vary the distance between the X-ray light source unit and the X-ray sensor unit. It includes a configuration that moves the position of the negative.

On the other hand, in dentistry, panoramic photography in which the patient rotates the head while standing is common. Therefore, if a patient with a history of panoramic imaging visits the hospital after, for example, more than 6 months have elapsed, it is often necessary to re-examine the patient for an accurate diagnosis.

However, since panoramic or dental CT must be taken in a standing state, it is necessary to adjust the position according to the height of the patient. Normally, it takes about 20 seconds to adjust the position according to the patient's height because the moving speed of the photographing part of the machine is slow.

Also, in general, for panoramic imaging machines, first, after “select patient” in the panorama shooting software, and then press the “wait for shooting” or “ready” button to initialize the machine, the dental staff takes the patient and enters the imaging room to measure the height of the imaging device. After adjusting it to fit the key, start shooting.

At this time, there is a delay of 2 to 30 seconds in the process of initializing the machine and adjusting it according to the patient's height, respectively.

The jaw support part and the X-ray sensor part automatically move to fit the patient's height, and the camera is ready for imaging.

In this case, the image capturing apparatus is set as it was set when capturing an image of the patient recently.

In the case of a pediatric patient in the growing stage, by adding an increase in height to the previous photographing position to reflect approximate growth, the position is automatically adjusted a little higher and the photographing standby state is established.

At this time, to reflect growth, the average height increment by gender and age can be applied according to the average height by gender and age from the National Statistical Office, etc.

More specifically, it can be reflected as a period of subtracting the date the patient took pictures in the past from today's date * average height increment by age. However, the present invention is not limited thereto.

In addition, the control system 10 of the image photographing apparatus according to an embodiment stores the photographing location in a database when the panoramic photographing is finished, so that the photographing location can be reused again next time.

It can be implemented in any data format that can control

For example, the database unit 150 matches and stores the patient's image capturing date and image capturing apparatus setting information at that time with patient identification information including patient-specific information.

In this case, the database unit 150 may store only image photographing apparatus setting information for the most recent photographing date for each patient. However, the present invention is not limited thereto, and may be implemented to record, accumulate, and store photographing history information.

The database unit 150 is a flash memory type (Flash Memory Type), a hard disk type (Hard Disk Type), a multimedia card micro type (Multimedia Card Micro Type), a card type memory (eg, SD or XD memory, etc.) , magnetic memory, magnetic disk, optical disk, random access memory (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), programmable memory (PROM) Read-Only Memory) may include at least one storage medium.

The image photographing device setting information stored in the database unit 150 includes z-axis (height) information of the photographing unit of the image photographing apparatus 20, for example, the X-ray sensor unit, and controls the height adjustment unit capable of adjusting the height. contains signals.

The device control unit 120 extracts image capturing apparatus setting information matching the patient to be photographed from the database unit 150 and outputs a control signal to the image photographing apparatus 20 according to the image photographing apparatus setting information during the recent photographing of the patient. do.

When receiving unique identification information such as a patient's name or resident registration number through the information input unit 110 , the device control unit 120 may extract recent image capturing apparatus setting information of the patient to be photographed from the database unit 150 .

Alternatively, the device control unit 120 reflects the height information of the first-time patient directly inputted to the information input unit 110 to adjust the height of the examinee's chin support for fixing the examinee's chin and the imaging device 20 to match the photographing position.

Correct.

For example, assuming that the average height of the patient's age statistically calculated at the time of the most recent photographing day is P1, and the average height of the patient's age statistically calculated at the time of the current photographing date is assumed to be P2, the correcting unit 130 is located at the position of the photographing unit during the latest photographing. By increasing the P2-P1 value, the image capturing device setting information may be corrected.

In this case, the correction unit 130 may secure the average height in units of years. Then, based on one year (365 days), the ratio of the number of days elapsed from the last filming date can be determined, and the growth rate of one unit can be calculated from the growth rate of the year on an annual basis.

In another embodiment, if the patient's height in the current growth stage is A, the corrector 130 determines the X value based on the relation P1:P2=A:X, and corrects the imaging device setting information based on the X value. can do.

However, the present invention is not limited thereto and is construed to encompass various modifications.

That is, in the case of a patient in the growing stage, the accuracy of automatic setting can be improved by correcting the image capturing apparatus setting information by reflecting the change in height in various ways.

According to a further aspect of the present invention, when a manual operation signal of the imaging apparatus is input, the updater 140 according to an exemplary embodiment updates the patient's imaging apparatus setting information stored in the database by reflecting the input manual operation signal. do.

That is, when a detailed manipulation signal by a dental staff in charge of image capturing is further input during actual shooting, the image capturing device setting information of the patient is updated and stored by reflecting the input.

In addition, when imaging of the patient is performed after that, image pickup device setting information reflecting detailed manipulation by the staff may be applied. Accordingly, as the shooting is repeated, the image capturing device setting information may be more accurately corrected.

In addition, when the patient's height information is manually input, the update unit 140 provides the database unit 150 with the identification information of the patient and the control signal of the imaging apparatus 20 generated according to the patient's height information. Save more.

2 is a flowchart of a method of driving a control system of an image photographing apparatus having an automatic setting function of a photographing position according to an embodiment of the present invention.

First, in the method of driving a control system of an image photographing apparatus having an automatic setting function of a photographing position, the information input unit receives patient identification information to be photographed (S200).

In this case, the imaging device includes a dental panoramic imaging device or a CT imaging device.

In an embodiment, the information input unit receives patient identification information directly by a medical staff or staff in a hospital. Alternatively, patient identification information may be input from another terminal provided in the hospital.

For example, the information input unit may receive input through a patient management program driven in a terminal in a hospital or a control program of an image capturing apparatus.

The patient identification information includes the patient's medical card information or name and date of birth information.

If a patient has had panoramic or CT scans at the hospital before, the imaging staff selects the patient from the panoramic imaging software.

After selecting a patient, press the “Standby” or “Ready” button in the shooting software for panoramic shooting to enter the shooting standby state.

The device controller extracts image pickup device setting information matching the patient to be photographed from the database unit that matches and stores the imaging device setting information to the patient identification information in the imaging standby state ( S210 ).

The database unit matches and stores the imaging device setting information with the patient identification information. At this time, the image capturing device setting information controls the height adjusting unit of the panoramic image capturing device, so that the examinee’s chin support and the X-ray sensor, which fix the examinee’s jaw, automatically move to the recent photographing position of the patient, so that the height for the photographing standby state. Contains control information.

That is, the image capturing apparatus setting information includes information on the height of the examinee's jaw support for fixing the examinee's chin, for example, z-axis (height) information of the photographing unit including the X-ray light source and the X-ray sensor.

The driving device included in the image capturing apparatus and capable of moving the height of the examinee's jaw support for fixing the examinee's jaw in the vertical direction can be implemented in various technical configurations, and the image photographing device setting information can control the various technical configurations described above. It can be implemented in any possible data format.

The device controller extracts image pickup device setting information matching the patient to be photographed from the database unit, and outputs a control signal to the image photographing device according to the image photographing device setting information during a recent photographing.

Alternatively, the device control unit may generate and output a control signal to the image capturing apparatus so that the photographing position can be adjusted by reflecting the key information of the first-time patient directly input to the information input unit.

As described above, the device control unit may determine the latest photographing location information based on the patient's photographing position information stored in the database unit, and automatically adjust the photographing position of the image photographing apparatus to the recently existing photographing position.

That is, for example, when a dental staff responsible for imaging an image presses the “wait for imaging” button, imaging units such as the X-ray light emitting unit and the X-ray light receiving unit of the imaging device automatically move to the imaging position of the patient and initially set the patient. The effect of saving the time of dental staff in charge of filming and imaging is derived.

In one aspect of the present invention, when the corrector corresponds to the growing age according to the patient identification information (S220), the image is captured by reflecting the elapsed period and average growth rate from the most recent photographing date in the extracted image photographing device setting information The device setting information is corrected (S230).

For example, assuming that the average height of the patient's age statistically calculated at the time of the latest imaging date is P1, and the average height of the patient's age statistically calculated at the time of the current imaging date is assumed to be P2, the compensator value P2-P1 at the location of the imaging unit during the latest imaging By increasing , the image capturing device setting information may be corrected.

In this case, the compensator may secure the average height in units of years. Then, based on one year (365 days), the ratio of the number of days elapsed from the last filming date can be determined, and the growth rate of one unit can be calculated from the growth rate of the year on an annual basis.

In another embodiment, if the height of the patient in the current growth stage is A, the corrector may determine the X value based on the relation P1:P2=A:X, and correct the imaging device setting information based on the X value.

Alternatively, the compensator may determine the X value based on the relation (P2-P1)=X-A and correct the image capturing apparatus setting information based on the X value. However, the present invention is not limited thereto and is construed to encompass various modifications.

That is, in the case of a patient in the growing stage, the accuracy of automatic setting can be improved by correcting the image capturing apparatus setting information by reflecting the change in height in various ways.

And according to an additional aspect of the present invention, when a manual operation signal for adjusting the photographing position of the image photographing apparatus is input by the updater (S240), the inputted manually operated photographing position is reflected to set the patient's image photographing apparatus stored in the database The information is updated (S250).

That is, when a detailed manipulation signal by a dental staff in charge of image capturing is further input during actual shooting, the image capturing device setting information of the patient is updated and stored by reflecting the input.

In addition, when imaging of the patient is performed afterward, image pickup device setting information reflecting detailed manipulation by an employee may be applied. Accordingly, as the shooting is repeated, the image capturing device setting information may be more accurately corrected.

When the patient's height information is manually input, the update unit further updates and stores the identification information of the patient and the control signal of the imaging apparatus generated according to the patient's height information in the database unit.

Thereafter, the device controller outputs a control signal to the image capturing device according to the image capturing device setting information identified in the database unit (S260).

And finally, the image capturing apparatus setting information output to the image capturing apparatus is stored or updated to match the patient identification information of the corresponding patient in the database again.
