The present invention relates to a patient alignment apparatus, and more particularly, to a patient alignment apparatus of the panoramic image recording apparatus that enables to align the head of the patient in a certain position when the patient is photographed with the dental panoramic image recording apparatus.

Dentists have traditionally used panoramic images of the entire tooth and alveolar bone using X-rays during treatment or orthodontics. In order to observe the progress of treatment or orthodontics with the panoramic image, several panoramic images must be taken. In order to determine the accurate progress, it is necessary to compare the images taken from a certain location each time.

In the panoramic imaging apparatus, an X-ray irradiation unit for radiating X-rays and a detector unit for detecting X-rays passing through a photographed portion rotate around the patient's head, so that the time required for photographing is higher than that of a conventional X-ray imaging apparatus. This is long. Therefore, the patient should not move when taking the panoramic image, in particular the head of the patient should be fixed without shaking in a certain position until the start and end of the imaging operation. Therefore, the patient's body and the head are not moved during the imaging process by using the support for the patient's jaw or the patient's bite block with the teeth to fix the head and the alignment device for the frontal and temporal heads. The method to use is used.

However, as described above, since panoramic photography is often not one-time, there is a problem that it is difficult to fix the tofu at the same position every time, even if the tofu can be fixed while the imaging is in progress. In particular, when the head of the patient is inclined toward the left and right shoulders or is slightly inclined in the horizontal left and right directions, there is a problem that the operator or the patient of the panoramic imaging apparatus is difficult to recognize.

1 is a side view illustrating a scene of photographing a panoramic image with a dental panoramic image photographing apparatus.

A typical dental panoramic image capturing apparatus 100 is elevated up and down on a pedestal 110, a support pillar 111 supported by a pedestal 110, and a support pillar 111, schematically supported by a floor of a building. Swiveling arm 150 rotatably coupled by the lifting unit 120, the upper frame 130 coupled to the upper portion of the lifting unit 120, the pivoting device 131 installed on the upper frame 130. It consists of. X-ray irradiation unit 152 and detector unit 154 are formed on both sides of the turning arm 150, respectively, X-ray irradiation unit 152 is irradiated X-rays, X-rays transmitted through the head 181 of the patient 180 is a detector The unit 154 converts the signal into an electrical signal, which is processed into image data that can be read by a controller (not shown).

The lower frame 140 is installed below the lifting unit 120. Handles 142 (not shown) are fixed to both sides of the lower frame 140, and a bite block 144 is formed at an end of the lower frame 140. While taking the panoramic image, the patient 180 holds the handle 142 with both hands and bites the bite block 144 with the teeth, so that the shoulder of the patient 180 descends to rotate the pivot arm 150. When the shoulder is shaken or turning to the turning arm 150 to prevent the jaw of the patient 180 is not shaken.

Meanwhile, the alignment device 160 is mounted on the head 181 of the patient 180. The alignment device 160 is equipped with a front head support member 162 and a temporal head support member 164a (the right temporal support member 164b is not shown) so that the line connecting the eyes and ears of the patient 180 is horizontal. Fix the head 181 so that the so-called horizontal eye (眼耳 水平) state.

2A and 2B are a plan view and a front view illustrating a state in which a head of a patient is aligned with a conventional alignment device, which will be described with reference to FIG. 1.

As described above, when the pivoting arm 150 is rotated to photograph the panoramic image, the X-ray radiator 152 and the detector 154 rotate about the head 181 of the patient 180, and the photographing ends. Head 181 should be fixed until it is.

However, as shown in FIG. 2A, the patient 180 bites the bite block 144 with the mouth, the front head support member 162 and the temporal head support members 164a, 164b being the front of the head 181 and the head. Even if both sides are supported, a problem may arise in that the head 181 is fixed in the direction 172 in which the face is turned to the horizontal side away from the direction 171 to be originally aligned. In particular, when the anterior of the patient 180 is damaged or absent or severe malocclusion, the above-mentioned problem is more likely to occur when taking a panoramic image, and when the jaw support is used instead of the bite block 144. Even if the mandible is severely asymmetrical, the same problem occurs. In addition, as shown in FIG. 2B, a problem may occur in which the head 181 of the patient 180 is fixed in a direction 174 which is inclined toward the shoulder away from the direction 173 to be originally aligned.

On the other hand, in order to protect the patient's eyes, the eyes are closed while the panoramic image is being taken. In the case of the hearing impaired, the instruction to close the eyes through sign language or a memo is required. There was a discomfort to make sure the patient was in the right position for the imaging.

Therefore, an object of the present invention is to overcome the disadvantages of the prior art as described above, by displaying a guide for aligning the head of the patient on the patient alignment device to allow the patient to align the head by looking at their own reflection image In addition, by providing instructions to patients with visual information such as not moving or closing their eyes while taking panoramic images, the convenience of the operator and patient of the panoramic imaging device is improved. In this case, the instructions can be delivered, so the shooting can be easily performed.

In order to achieve the above object of the present invention, a screen coupled to one side of the panoramic imaging apparatus, and a guide for displaying a guide for aligning the head of the patient on the screen, the screen of the patient in the shooting position A patient alignment device is provided that reflects the appearance.

The part of the screen except for the guide part may include a mirror-machined metal material so that the patient's reflection image is easily visible to the patient, and corresponds to the front panel, the reflective film coupled to the rear surface of the front panel, and the guide part on the rear surface of the reflective film. Lighting means for irradiating light at a position to be included, wherein the reflecting film is configured to include a material which transmits all or part of the light irradiated from the lighting means so that the guide overlaps with the reflection of the patient only when the lighting means is operated. You can also

The reflective film may be made of a material used for manufacturing a conventional mirror such as aluminum, gold, silver, or mercury on one surface of the front panel, and a light shielding film may be added to the reflective film so that the guide appears in a clear shape. One or more vertical alignment lines or one or more horizontal alignment lines may be used for the guide, and it is also possible to further add auxiliary lines in parallel lines spaced apart from each other. In addition, it is possible to provide various visual information to the patient by adding a display unit to the screen.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the patient alignment device according to the present invention. However, the same or corresponding components will be given the same reference numerals and redundant description thereof will be omitted, and detailed descriptions of well-known technologies that are determined to obscure the spirit of the present invention will be omitted. In addition, when description is required in connection with the overall structure of the panoramic image capturing apparatus, it will be described with reference to FIG. 1.

3A is an exploded perspective view showing the structure of a first embodiment of the present invention, and FIG. 3B is a front view showing the first embodiment shown in FIG. 3A. 3A and 3B, the screen 210, the front panel 211, the reflective film 212, the light shielding film 280, the slit portion 281, the opening 284, the circuit board 270, and the lighting means ( 271, the display device 274, the display unit 250, the vertical alignment line 231, and the shipbuilding 232 are illustrated.

The screen 210 of the patient alignment device 200 includes a front panel 211 and a reflective film 212 formed on one surface of the front panel 211. As the material of the front panel 211, both synthetic resins such as acrylic, ABS resin, polycarbonate, or glass may be used, and in particular, such as an extruded acrylic plate, the light transmittance is excellent, the price is low, and is not easily broken. It is preferable.

The reflective film 212 formed on one surface of the front panel 211 may be vacuum-deposited aluminum on the front panel 211 or coated with a high-purity aluminum foil on the front panel 211. As the material of the reflective film 212, various materials including at least one of gold, silver, mercury, zinc sulfide, and rhodium, in addition to aluminum, may be used. It is easy to form the reflective film 212 and use an inexpensive material. Preferably, the reflective film 212 may be arbitrarily selected and used according to the needs of the user, such as considering the reflectance and the beautiful color.

The lighting means 271 is installed in the direction in which the reflective film 212 of the front panel 211 is formed to irradiate light toward the reflective film 212. The plurality of lighting means 271 are installed on a circuit board 270 electrically connected to a controller (not shown). The controller (not shown) controls the overall operation of the panorama photographing apparatus 100 and processes image information included in the X-ray received by the detector unit 154. The reflective film 212 of the screen 210 has the property of passing the light irradiated from the luminaire 271 as much as possible and reflecting the light irradiated from the opposite direction as much as possible. Therefore, when light is irradiated from the luminaire 271, the light of the luminaire 271 may be visually confirmed from the front of the front panel 211, but if the luminaire 271 does not irradiate light, the reflective film 212 may be used. This allows the screen 210 to look like a conventional reflector. Since the translucent mirror having such a characteristic is a known technique, detailed description thereof will be omitted.

One or more display devices 274 are installed on the circuit board 270. The display device 274 includes a plurality of light emitting devices arranged to display text or images and an image output device using an LCD or a PDP. Can be. Visual information such as a character or an image displayed by the display device 274 can be easily visually identified through the screen 210 by appropriately adjusting the brightness of the display device 274.

The patient may align the head while looking at his reflection image 182 reflected on the screen 210 of the patient alignment device 200. The guide displayed on the guide portion 230 on the screen 210, that is, the vertical alignment line The head is aligned using the auxiliary line 232 displayed at a predetermined interval apart from the 231 and the vertical alignment line 231. Therefore, in order for the patient to see his reflection image 182, it is preferable that the patient alignment device 200 is mounted on one surface of the lifting unit 120 positioned in front of the face of the patient 180 at the photographing position.

As described above, when only the front head support member 162, the temporal head support members 164a and 164b, and the bite block 144 are used, the head of the patient is not aligned correctly and the head is turned in the horizontal left and right directions or the head Since it may be fixed in a state where it is inclined to both shoulders and deviates from the vertical, the patient may self-reflex image using the vertical alignment line 231 and the auxiliary line 232 so that the head is not taken out of the horizontal left and right or vertical. The center of the display unit 182 may be aligned with the vertical alignment line 231. At this time, the auxiliary line 232 is displayed at intervals spaced apart from the vertical alignment line 231 within the allowable range in order to reduce the mental burden that the patient should align the head exactly to the vertical alignment line 231.

The display unit 250 formed on the patient alignment apparatus 200 displays visual information 255 including guidance or promotion of a hospital visited by a patient, guidance of a panoramic image capturing procedure, instructions during shooting, and the like. In particular, the patient's eyes are closed to protect the eyes of the patient during the panoramic image capture. The visual information 255 indicating these instructions may be represented as a plurality of still images or moving images as well as text. For example, as the visual information (255), the name or promotion of the dentist, "Start shooting", "Please fix the head to the shooting position", "Close your eyes", "Thank you for using our dentist Thank you." If you print out the characters necessary for publicity or shooting, the hearing impaired person can also see the visual information (255) and cooperate with the shooting procedure. In addition, it is easy to convey an instruction on the shooting procedure.

Typically, the operator of the panoramic image capturing apparatus 100 is outside the space in which the panoramic image capturing apparatus 100 is installed in order to reduce the radiation exposure amount during the photographing process. Therefore, since the patient should be in the photographing position alone until the photographing procedure of the panoramic image is completed, the patient may have anxiety. In this case, the visual information 255 may be provided to the patient 180 by providing information on health or publicity about the dentist, thereby reducing the anxiety of the patient. Accordingly, it should be apparent to those skilled in the art that the operator of the panoramic image photographing apparatus 100 should be configured to easily input, change, and store the contents of the visual information 255 in a controller (not shown) as needed. It is thought.

The plurality of lighting means 271 mounted on the circuit board 270 is disposed at a position corresponding to the guide, that is, the vertical alignment line 231 and the auxiliary line 232 of FIG. 3A, and the display device 274 is a display unit. It is disposed at a position corresponding to 250. Accordingly, the light irradiated from the luminaire 271 passes through the screen 210 and is visible to the patient as the vertical alignment line 231 and the auxiliary line 232, and the information displayed on the display device 274 is displayed on the screen 210. It is displayed on the display unit 250 located in a portion of the. Since the display device 274 may be mounted at any position on the circuit board 270 according to a user's needs, the position of the display unit 250 on the screen 210 is formed at a position corresponding to the display device 274. It is desirable for the patient to be formed at a position where the visual information 255 is most easily recognized.

The light shielding film 280 is formed on the reflective film 212 using a coating or adhesion method. The light blocking film 280 limits the range of light irradiated from the luminaire 271 so that the light transmitted through the reflective film 212 may appear in a predetermined shape. The light shielding film 280 uses a material having excellent light shielding properties and may be processed into a film form, which is a well-known technology, and thus a detailed description thereof will be omitted.

One or more slit portions 281 are formed in the light shielding film 280 at positions corresponding to the lighting means 271, and the same number of openings 284 as the display apparatus 274 are formed at positions corresponding to the display apparatus 274. The light emitted from the luminaire 271 and the display device 274 is not blocked. On the other hand, light rays incident from the patient's direction of the screen 210 are mostly reflected by the reflective film 212, and the light shielding film 280 is formed in a portion where the slit portion 281 or the opening 284 of the light shielding film 280 is not formed. Since the remaining light beams passing through the reflective film 212 are also blocked, the screen 210 looks like a conventional reflector regardless of whether the luminaire 271 and the display device 274 are operated.

As described above, when a point light source such as a plurality of light emitting diodes is used as the lighting means 271 and the display device 274, the guide displayed on the screen 210, that is, the vertical alignment line 231 and the auxiliary line 232 is shown as a dotted line to the patient, or the pixels of the visual information 255 become prominent. Accordingly, the light emitting device used in the vertical alignment line 231, the auxiliary line 232, and the display device 274 uses a diffusion type light emitting diode, or the light blocking film 280, the lighting means 271, and the display device 274. The vertical alignment line 231 and the auxiliary line 232 on the screen 210 by diffusing the light generated from the luminaire 271 via a diffuser film (not shown) which diffusely reflects light between It can be shown by a solid line, and the pixel of the time information 255 displayed by the display apparatus 274 can be made invisible. In addition, by using a line light source such as a cold cathode lamp (Cold Cathode Fluorescent Lamp) as the lighting means 271, or using an optical lighting film (OLF) in which a plurality of fine prisms are formed on the surface instead of a diffusion film (not shown) It is also possible to have a point light source, such as a light emitting diode, perform the function of a line light source.

In addition, a display such as "is doing the best for accurate diagnosis and treatment using an advanced digital system" displayed around the display unit 250 may be printed on the front panel 211 in advance and the reflective film 212 may be formed. Irrespective of whether the light emitting element 271 and the display device 274 irradiate light, the light emitting element 271 and the display device 274 may always be visible to the patient. After the reflective film 212 is formed, a display is printed on the surface of the reflective film 212 and the light shielding film is formed. A separate opening (not shown) is formed in the corresponding area at 280, and a separate light emitting device (not shown) is added to the circuit board 270 so that a separate light emitting device (not shown) emits light. It is also possible to make it visible only when investigating.

On the other hand, by arranging a plurality of lighting means (271) on the entire surface of the circuit board 270, the character and the image to the lighting means 271 at the position corresponding to the display unit 250 without mounting the display device 274 separately It is also possible to display, and a flat fluorescence lamp is used as the lighting means 271, and the vertical alignment line 231 and the auxiliary line 232 are screened by using the slit portion 281 of the light shielding film 280. The display unit 274 may be installed on the entire surface of the circuit board 270 so that the entire screen 210 may be the display unit 250, and the guide, that is, the vertical alignment line 231. ) And the auxiliary line 232 may be linearly output. Accordingly, the guide unit 230 may be included in the display unit 250, and guides such as the vertical alignment line 231 and the auxiliary line 232 may also be implemented as visual information 255 represented on the display unit 250. .

In addition, a voice output unit (not shown) may be added to the control unit (not shown) to control the display unit 274 so that the voice information is output together with the time information 255. . "," Close your eyes "," Be careful not to move your head "," I'm done shooting "," Thank you for using our dentist. " The patient may be provided with instructions for the procedure or publicity of the dentist performing the imaging. In particular, when the patient is visually impaired, the patient may easily cooperate with the photographing by transmitting instructions necessary for photographing by voice.

Figure 4 is a front view showing the irradiation of the alignment beam to the head of the patient, Figure 5 is a front view showing a second embodiment of the present invention. It will be described with reference to Figure 1 together.

Typically, at least one beam irradiator (not shown) for irradiating a linear beam onto a patient's face is installed in the panoramic image photographing apparatus 100 to display an alignment line directly on the face of the patient. One or more beam irradiation units, not shown, includes a vertical beam 291 representing a vertical line at the front center of the head 181, a horizontal beam 292 and a canine area representing a horizontal line passing through the cheekbones by connecting the vicinity of both ear holes. Irradiate each canine beam 293 passing through. The vertical beam irradiator for irradiating the vertical beam 291 is connected to the upper frame 130 and the elevating unit 120, the horizontal beam irradiator is at one side of the elevating unit 120, and the canine beam irradiator is the lower frame 140. Respectively).

At this time, using the patient alignment device 200 according to the present invention, the patient 180 is a vertical alignment line displayed on the vertical beam 291 directly displayed on the head 181 and the reflection image 182 reflected on the screen 210. While it is possible to more easily align the head using 231, the vertical beam 291 is covered by the frontal head support member 162 so that the vertical beam 291 is not easily displayed on the forehead. .

Therefore, when the vertical beam irradiation unit is embedded in the patient alignment device 200 to irradiate the vertical beam 291 through the beam irradiation unit 290 of the screen 210, the vertical beam irradiation unit outside the panorama imaging apparatus 100. Not only is it aesthetically advantageous because it is not exposed, but also the effect of preventing the vertical beam 291 from being blocked by the frontal head support member 162 can be obtained.

Meanwhile, the vertical beam 291, the horizontal beam 292, and the canine beam 293 may be virtually represented on the screen 210 without directly irradiating the head 181. After photographing the head 181 using a camera (not shown), an image of the head 181 is displayed on the guide unit 230, and the guides such as the vertical alignment line 231 and the auxiliary line 232, and the like. When displayed together, the patient 180 can align the head 181 by itself, and store the database of the alignment state of a specific patient in the control unit (not shown), and compare the images when the image is taken again. It is also possible to send instructions to correct the alignment.

6 is a front view showing a third embodiment of the present invention.

The patient alignment device 200 further displays the horizontal guide line 221 and the auxiliary line 222 in addition to the vertical guide line 231 and the auxiliary line 232, thereby allowing the patient to head himself while looking at the reflection image 182. It is possible to obtain a larger effect of preventing the tilting of the shoulder toward both shoulders. Even in this case, it is desirable to display one or more auxiliary lines 222 spaced apart from the horizontal alignment line 221 within a range that allows the patient to reduce the mental burden on the head alignment state.

In addition, since the surface of the screen 210 is always exposed, it is easy to cause scratches or the like on the surface due to prolonged use, dust may be attached to the room, and the reflectance may be lowered. The patient may be disturbed in viewing the reflex image 182. Therefore, it is desirable to apply a coating on the patient side surface of screen 210 to reduce antistatic and surface reflection.

Although the preferred embodiments of the present invention have been described above, those skilled in the art may variously modify and modify the present invention without departing from the spirit and scope of the present invention as set forth in the claims below. It will be appreciated that it can be changed. In addition, the present invention can be applied not only to panoramic imaging, but also to the head imaging of various patients, such as taking a cephalograph (cephalogram or cephalometric image), the screen is a mirror panel (패널 面 加工) metal panel And a method of displaying the guide directly on the guide unit may be used.
