Description

  The present invention relates to a system for generating ophthalmic images, and more particularly to an ophthalmic image generating system that receives examination information from a hospital information system via a network and determines the type of image to be captured based on the examination information.

An image generation and storage system that receives examination information from an information system in a hospital upstream, captures a medical image based on the information, and stores the captured image again in an image server on the network is mainly X In the case of an X-ray image that is designed around a line image and whose imaging technique is standardized, it is customary that the apparatus itself is not allowed to determine the type of examination.
JP-A-6-202254

Unlike X-ray imaging equipment, where most monochrome images are used,
In addition to normal color photography such as fundus cameras and slit lamps, there are various photography techniques (photographing types) such as fluorescence photography and special filter photography as in ICG photography.

  In addition, the doctor who conducts the examination took a picture on the spot by selecting the technique, magnification, photographing region (including left and right eye changes), and the number of images.

  Therefore, not all of the above-mentioned conditions, which can be called imaging conditions, are always described in the inspection information in the inspection request to such an apparatus.

  A configuration in which the shooting type can be determined by operating the device itself is usually used.

  Therefore, when an ophthalmic imaging device such as a conventional fundus camera is connected to an image generation / storage system that is mainly considered for X-ray images as described above, a system designed for X images and a conventional ophthalmology It was difficult to maintain consistency with the operation of the equipment.

  An object of the present invention is to solve the above-described problem, and in an ophthalmologic image generation apparatus having various imaging types, an inspection request determined from upstream while maintaining a configuration in which the imaging type can be determined by operation of the apparatus itself The purpose is to build a system that can shoot according to the items and decide the optimal shooting conditions by selecting the procedure, shooting magnification, shooting site (including left and right eye changes), and the number of shots at the time of shooting. To do.

  The system of the present invention is an ophthalmic image generation system including an imaging head that generates an electronic image and a control PC that controls the imaging head, and a communication path that connects between the imaging head and the control PC. Two operation units for switching the image capturing type (for example, Color / FA / ICG, the contents of which will be described later), and when the operation unit is operated, from the side where the operation is performed to the other A communication control unit that transmits imaging type information, and each of the imaging head and the control PC performs an operation related to imaging according to the output of the operation part or the captured imaging type information received by the communication control unit. It is possible to switch. Furthermore, when the imaging head is not connected to the control PC, film shooting is possible, and the transmitted shooting type information indicates the shooting mode in the case of transmission from the PC to the imaging head. The imaging head that is the switching request and receives the imaging mode switching can transmit the imaging mode switching notification to the control PC after switching the imaging mode. The control PC may include inspection request management means for generating or receiving inspection request information having the photographing type information, and the photographing type information may be generated by an output of the inspection management means.

  As described above, in the ophthalmic image generation system according to the present invention, even if the ophthalmic image generation system includes an imaging head that generates an electronic image and a control PC that controls the imaging head, Can be taken according to the inspection request item determined from the upstream while maintaining the configuration that can be determined, and the technique, shooting magnification, shooting site (including left and right eye replacement) The optimum shooting conditions can be determined by selecting the number.

  Furthermore, in addition to configuring the fundus camera head to take the initiative in selecting the shooting type, film shooting is performed by managing and controlling common parameters used for film shooting instead of electronic imaging on the shooting head side. In this case, the operation of the fundus camera head alone can be performed, and the operability with the conventional fundus camera that does not perform electronic imaging can be matched. In addition, the control PC provides inspection request information having the imaging type information. The inspection request management means that is generated or received can be compatible with the system that generates the photographing type information without any contradiction.

  In addition, it confirms whether the shooting type is described in the inspection request, and if it is different, a screen is displayed to confirm whether it is possible to perform shooting outside the inspection request, and the operation branches depending on the response of the examiner to this screen. By doing so, it is possible to further reduce operation errors.

(Example 1)
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an example of a fundus camera system that is an embodiment according to the present invention. The fundus camera head 1 for photographing the fundus and the control PC 2 are connected by a communication path 3 for data transfer. An image photographed by the fundus camera head 1 is transferred to the control PC 2 via the communication path 3, and the other communication path 3 is used for exchanging various information between the fundus camera head and the control PC. The control PC 2 is further connected via a local area network 4 to a host system 5 for generating and managing inspection request information and an image server 6 for permanently storing images, and managing the host system 5 at the beginning of inspection. Operation such as obtaining examination request information to be performed, associating temporarily stored captured images with supplementary information such as patient information, and registering them in the image server 6 is performed. Here, the host system 5 is not indispensable, and if it is not present, the control PC 2 can be configured to generate inspection request information.

  In FIG. 1, the fundus camera head is equipped with a plurality of photographing devices 7 and 8 having an electronic image pickup device. However, it is possible to attach a film photographing device capable of photographing a film as well. In such a case, the film can be taken independently of the control of the control PC 2. In this way, a system that enables film photography is effective in performing matching with a conventional fundus camera photographing operation. The operation panel 10 and 11 for selecting the type of imaging (to be described later in detail) to be performed in the operation panel and the control PC below the fundus camera head 1 are prepared. In the present embodiment, the control unit 11 of the control PC is a PC keyboard, but actually means an operation unit for operating an application program activated on the PC. Physically, another pointing device such as a mouse is used. Actually, however, the application program selects an option (for example, a selection table display window such as 12) displayed on the display for prompting selection.

  FIG. 2 is a sectional view of the structure of the fundus camera head. In FIG. 2, an objective lens 103, an anterior eye / fundus switching lens unit 104, a perforated mirror 105 having a central aperture, a corneal baffle 106, a relay lens are provided on an optical path A from an eye 101 to an observation light source 102 such as a halogen lamp. 107, a lens baffle 108, an ultraviolet cut filter 109, an exciter 110 for visible fluorescence imaging, an exciter 111 for ICG fluorescence imaging, a ring slit unit 112 having an annular opening and a plurality of rings arranged to correspond to the small pupil diameter, Concave reflectors 116 are sequentially arranged on the back side of one condenser lens 113, a fundus photographing light source 114 such as a xenon lamp that emits strobe light, the second condenser lens 115, and the anterior eye observation light source 102. On the optical path B behind the perforated mirror 105, a fundus image is photographed by a visible fluorescent photographing barrier filter 117, a focus lens 118, a photographing lens 119, a first tiltable mirror 120, and an electronic imaging device 121 such as a CCD. The fundus imaging device 122 is arranged, and the captured image output of the fundus imaging device 122 is sent to the imaging control unit 129. There is a finder having a second tiltable mirror 123 and an eyepiece 124 on the optical axis C switched by the first tiltable mirror 120. Further, on the optical axis D switched by the second tiltable mirror 123, a moving image imaging device 128 for observing the anterior segment with an electronic imaging element 127 such as a mirror 125, an ICG imaging barrier filter 126, and a CCD. And the moving image output of the moving image capturing device 128 is sent to the shooting control unit 129.

  In addition to the fundus imaging device 122 and the moving image imaging device 128, the imaging control unit 129 is provided in the captured image recording device 130 that temporarily stores image data captured by the fundus imaging device 122, the display device 131, and the operation rod 132. The photographing button 133, the interface device 134 with the control PC, and the emitted light amount control device 135 of the fundus photographing light source 114 are connected.

  The actual operation of the fundus camera head having the above configuration is determined by the photographer selecting the following photographing types (1) to (4).

(1) COLOR
Full-color photography using visible light. The observation image light beam from the observation light source 102 becomes an annular light beam by the ring slit unit 112, is reflected by the perforated mirror 105, passes through the objective lens 103, and illuminates the fundus of the eye 101 to be examined. The reflected image from the fundus is a viewfinder image that passes through the objective lens 103, the hole of the perforated mirror 105, the focus lens 118, the imaging lens 119, the first tiltable mirror 120, the second tiltable mirror 123, and the eyepiece lens 124. It becomes.

  Furthermore, when the photographer presses the photographing button 133 while focusing, confirming the photographing part, confirming the presence or absence of flare, the first retractable mirror 120 is retracted out of the optical path B, and the fundus photographing light source 114 emits light, The light beam illuminates the eye 101 as in observation, and the fundus image passes through the objective lens 103, the aperture of the perforated mirror 105, the focus lens 118, and the photographing lens 119 on the electronic image sensor 121 of the fundus photographing device 122. As a still image, the image is recorded on the captured image recording device 130.

  The fundus image recorded in the captured image recording device 130 is displayed on the display device 131 and transferred to the control PC (2) via the interface device 34. In this photographing type, a photographing interval of about 1 frame / 3 seconds is allowed in consideration of the transfer time.

(2) FA (continuous shooting mode)
Fluorescence photography using visible light. After intravenous injection of a luminescent dye in the visible wavelength range to the subject, an exciter is inserted in the illumination system optical path and a barrier filter is inserted in the imaging system optical path, and continuous imaging corresponding to a maximum of 1 image / second of the blood vessel modeling image of the fundus blood vessel Shooting method to do.

  The observation image light beam from the observation light source 102 is converted into an annular light beam by the ring slit unit 112, then the specific wavelength light for excitation is selected by the visible fluorescence imaging exciter 110 and reflected by the perforated mirror 105, The fundus of the subject eye 101 is illuminated through the objective lens 103. The coloring dye excited by the illumination light generates fluorescence shifted to the long wavelength side in the excitation wavelength region, and forms a blood vessel. This blood vessel image passes through the hole portion of the objective lens 103 and the perforated mirror 105, and after selecting only fluorescence by the visible fluorescent photographing barrier filter 117 that transmits only the fluorescence wavelength region, the focus lens 118 and the imaging lens 119 are selected. A viewfinder image that passes through the first retractable mirror 120, the second retractable mirror 123, and the eyepiece 124 is obtained.

  Further, the photographer focuses while observing the finder image, confirms the photographing part, confirms the presence or absence of flare, and presses the photographing button 133. Then, the first retractable mirror 120 is retracted out of the optical path C and is used for fundus photographing. The light source 114 emits light, and the luminous flux illuminates the eye 101 as in observation. The fundus image is the objective lens 103, the aperture of the perforated mirror 105, the visible fluorescent photographing barrier filter 117, the focus lens 118, and the photographing lens. Through 119, an image is formed on the electronic image sensor 121 of the moving image capturing device 122 and recorded in the captured image recording device 130. This recording can be repeated at a maximum of 1 frame / second. The fundus image thus captured is displayed on the display device 131 for each still image frame, and transferred to the control PC (2) via the interface device.

(3) FA (High-definition mode)
This is fluorescence photography using visible light similar to (2).

  In the main photographing type, unlike (2), the image data recorded in the photographed image recording device 128 is a still higher-definition still image that is displayed on the display device 129 and via the interface device 128. It is transferred to the control PC (2). In this photographing type, a photographing interval of about 1 frame / 3 seconds is allowed in consideration of the transfer time.

(4) ICG
Fluorescence photography using near infrared rays. After intravenous injection of a luminescent dye in the near-infrared wavelength region to the subject, an exciter is inserted in the illumination system optical path, and a barrier filter is inserted in the imaging system optical path, corresponding to a maximum of 1 image / second of blood vessel modeling images of the fundus blood vessel Shooting method that performs continuous shooting.

The observation image light beam from the observation light source 102 becomes an annular light beam by the ring slit unit 112, the specific wavelength light for excitation is selected by the ICG fluorescence imaging exciter 111, reflected by the perforated mirror 105, and the objective lens 103. And the fundus of the eye 101 to be examined is illuminated. The coloring dye excited by the illumination light generates fluorescence shifted to the long wavelength side in the excitation wavelength region, and forms a blood vessel. This blood vessel image passes through the objective lens 103, the hole of the perforated mirror 105, the focus lens 118, the imaging lens 119, and the first tiltable mirror 120. At the time of ICG moving image observation, the second retractable mirror 123 is retracted to the broken line portion, so that the observation image light source passes through the optical axis D, passes through the mirror 125, and the ICG imaging barrier filter 126. An image is formed on the electronic image sensor 127. The formed fundus image is displayed on the display device 131. Further, the photographer focuses while observing the fundus image displayed on the display device 131, confirms the imaging region, and checks the presence or absence of flare. When the button is pressed, the fundus imaging light source 114 emits light, and its luminous flux illuminates the eye 101 as in observation, and the fundus image is the objective lens 103, the aperture of the perforated mirror 105, the focus lens 118, and the imaging lens 119. The fundus image formed on the electronic imaging device 127 of the fundus imaging device 128 through the first tiltable mirror 120, the mirror 125, and the ICG imaging barrier filter 126 is recorded as a still image on the captured image recording device 130. Is done. The still image recorded in the captured image recording device 130 is displayed on the display device 131.

  When the imaging type is selected, the imaging parameters according to the selected imaging type are read from the control PC (2), and the fundus imaging device 122, the moving image imaging device 128, the captured image recording device 130, and Setting to the light emission amount control device 135, together with image data taken after photographing, to the control PC (2) via the interface device 134, the machine number of the device, distinction of the right and left eyes, photographing angle of view, photographing time, etc. The two operations of being transferred together with the photographing information of the fundus camera head are common in the above modes.

  Hereinafter, how to determine the above-described four shooting types and common processing thereafter will be described. First, a case where the shooting type is determined from the control PC 2 is shown. FIG. 3 is a window in which examination information managed in the upstream system is displayed on the control PC 2 as an examination list. The examination list table includes a patient ID (302) as a subject and imaging management information ( 303), the eye to be photographed [left / right] (304) is displayed. Therefore, when the imaging type has already been specified in the inspection request, the inspection type is automatically selected by selecting the next inspection (305) to be performed from this inspection list, and the control PC (302). The imaging type and the imaging parameters depending on the imaging type are transferred to the fundus camera. Also, in the case of 306 where there is no designation in the examination information, the photographing type can be determined by operating the pull-down menu on the spot. In this embodiment, the above two types are described in the method of determining the photographing type from the control PC. Actually, these two types are determined depending on various configurations of the upstream system that manages the examination request and the operation method in the hospital facility. The operation will be decided by selection and combination from. For example, in the case of an operation mode in which the inspection type is not entered, or when the inspection request is made by the control PC itself, the imaging type is determined from the control PC, and conversely, the inspection type is assigned to all inspections by the inspection request. In the operation mode in which the entry of is required, it is only necessary to select the next inspection itself. In addition to the selection of the photographing type from the control PC as described above, the system according to the present invention can also select from the fundus camera head side. FIG. 4 is a photographing type selection switch arranged on the fundus camera head operation panel 400, and basically three switches for selecting the above-described three types of color 401, FA 402, and ICG 403 as the photographing type are prepared. ing. On the operation panel 400, a timer switch for performing other operations, for example, storing the intravenous injection time of the fluorescent dye in the apparatus is similarly arranged. Since the selection of the above-described shooting types FA1 and FA2 is basically switching between modes of FA, a switch 411 of 1 and a switch 412 of 2 are prepared which are valid only when the FA 402 is pressed. , 1 is enabled by default when FA is pressed. The switch 2 is selected by the operator as needed. In other words, the examiner uses this function to capture one frame per second at the initial stage of angiography using “FA1”, and then, when recording a higher-definition image, switches the timely imaging type and provides high-resolution, low-image compression. Record high definition images. In this switched recording, only one frame can be taken every 3 seconds. However, in the latter stage of angiography, the contrast medium is completely around the fundus, so high-speed repeated photography is unnecessary, so this switched photography is effective. It is. As described above, in this system, the photographing type can be selected from both the control PC 2 and the fundus camera head 1, but basically the operation from the control PC 2 is the principle.

  After the selection of the shooting type described above is performed by any of the methods, the examiner performs the above-described operations to perform various types of shooting, but is defined by the setting of the shooting type managed by the control PC. In addition to the imaging parameters, switching of the optical path managed and controlled on the fundus camera head side, insertion / removal of various filters, switching of the imaging device, and adjustment of the light emission amount are simultaneously performed. Here, the parameters managed and controlled on the fundus camera side are common parameters used not only for electronic imaging but also for film shooting, and film shooting is performed by managing and controlling these parameters on the fundus camera head side. In this case, not only the operation of the fundus camera head alone becomes possible, but also the operability with the conventional fundus camera that does not perform electronic imaging can be matched. (The processing when there is a contradiction between the selections of both will be described later.) When photographing is completed, the fundus camera head now has the image data along with the image data via the communication path to the control PC as described above. Device photographing information of the fundus camera head such as number, right eye / left eye distinction, photographing angle of view, photographing time, etc. is transferred. The control PC associates and saves the examination information including the patient information and examination type managed by the control PC itself, the imaging information, and the image data, and saves it to an external image server as needed. Data is transferred.

  FIG. 5 shows a window for changing the imaging parameters of the fundus camera managed by the control PC (2). The shooting parameters 501 are configured as a group subordinate to the shooting type (COLOR / FA1 / FA2 / ICG). Here, each parameter will be briefly described.

・ ISO
Sets the sensitivity of the image sensor. Here, 100/200, 400, or 800/1000 is selected.

・ CONTRAST
Sets the contrast strength.

・ SHARPNESS
Sets the strength of edge enhancement processing.

・ DARKNESS
Set the brightness fine correction amount.

・ HUE
Set the hue.

・ WHITE BALANCE
Set the white balance. Set in the range of 2000K-10000K.

  If “B / W” is selected, monochrome conversion is performed and a monochrome image is recorded even when the image sensor picks up a color image.

・ EXPOSURE
The exposure correction value is selected from -2 / -1, 5 / -1 / -0, 5/0 / + 0, 5 / + 1 / + 1, 5 / + 2.

・ IMAGE SIZE
The resolution of the captured image is selected from LARGE / MIDDLE / SMALL.

・ Quality
The compression rate for recording an image is selected from FINE / NORMAL / RAW.

-Minimum shooting interval The minimum shooting interval determined from the image file size determined or estimated from IMAGE SIZE and QUALITY and the file transfer speed between the control PC and the fundus camera is automatically calculated and displayed.

・ LEVEL
The correction value of the emitted light quantity is set in the range of −10 to +10.

  Next, the method for determining the shooting type according to the present embodiment will be described step by step with reference to FIG. When the examination list is displayed 601 on the control PC (2), the examiner can select 602 the next examination from the list. When this selection is made, the fundus camera head is notified of an imaging type change request in accordance with the examination type written in the examination information. The fundus camera head receives it, and sets 603 a shooting mode according to the shooting type. That is, items managed and controlled on the fundus camera head side, such as switching of optical paths, procedures for inserting / removing various filters, switching of photographing apparatuses, and adjustment of light emission amount. When these settings are completed, the change of the photographing type is notified from the fundus camera head to the control PC. Upon receiving this notification, the control PC performs processing such as an image reception method and a user interface switching by the control PC, and then refers to the subordinate shooting parameter file determined by the above-described shooting mode, and the fundus camera Notify the head of the contents. The fundus camera head sets the content in the head 606, and further prohibits photographing parameter operation on the fundus camera side. The process waits 605 for input by an input of the shooting switch. Next, a case where the photographing type is changed from the fundus camera head side will be described. As described above, the fundus camera head can change the photographing type by operating the photographing type selection switch on the operation panel 300. The fundus camera head sets 610 a shooting mode according to the shooting type in accordance with the input. After these settings are completed, the change of the photographing type is notified 611 to the control PC. Upon receiving this notification, the control PC confirms whether or not the photographing type is described in the inspection request, and if different, displays a screen for confirming whether photographing outside the inspection request can be performed 612. The operation branches depending on the examiner's response to this screen, but if an operation other than the inspection request is not desired, it is determined that the operation of the fundus camera head is erroneous, and the process returns to the inspection request list display 601 or the type of imaging. Display a message prompting you to select the most. In the present embodiment in which the flow is formed based on the inspection request, it is desirable to make a branch to return to the registered inspection list display. For example, there is no upstream system, and the control PC itself is configured to issue the inspection request. The system can be configured to accept an inspection request here. If the examiner performs an operation when an operation other than the inspection request is desired, the control PC switches the image receiving method, the user interface, etc., as in the case where the photographing type is selected from the control PC. After the above processing is performed, the subordinate shooting parameter file determined by the above-described shooting mode is referred to, and the contents are notified to the fundus camera head. Here, the control PC further prepares for the formation of a new image group within the same examination. An image group here refers to an aggregate of a plurality of images that can be collectively determined at home when a specific image is reached when referring to the image after shooting. In the present embodiment, which presupposes that the type of imaging is described in the inspection request, in principle, there is only one image group created by this type of imaging for each inspection. However, here, when an imaging type different from the description in the examination request is set from the fundus camera head side, in this case, two image groups with different imaging types are generated in the same examination. Forming such an image group is not only easy to understand what type of imaging was performed in the examination of the day, but also as an effective search key when the examiner searches for a specific image. It has a great effect on improving operability. After that, the fundus camera head sets the contents in the head, and then prohibits the photographing parameter operation on the fundus camera side. It is the same as the previous operations 605-606 that the user waits for shooting 614 by input of the shooting switch. Thereafter, when the photographing button on the operation rod 132 of the fundus camera head is operated, actual photographing is performed, and image data is transmitted 615 in association with the apparatus information collected by the fundus camera head. In response, the control PC registers an image as a new image group 616.

  The operations of the above-described examination list display 601 to photographing standby 606 and the examination type change 610 to photographing standby 614 can be performed in any order. In the system of the present invention, this series of operations is performed. The right to determine the photographing type always lies in the fundus camera head, and the notification issued from the control PC is only a request for changing the photographing type to the fundus camera head. For this reason, even when the fundus camera is separated from the control PC that performs film shooting, for example, and performs a single operation, there is no contradiction in the operation. In addition, in the operation, if a communication that allows both the control PC and the fundus camera head to confirm the state of each other is added, a more stable system can be constructed.

  For the above-described image group formation, it is also possible to use device information collected by the fundus camera head that is sent together with the image data in addition to the shooting type, that is, right eye left eye discrimination, shooting angle of view, and the like. Here, an example in which an image group is formed according to the types of left and right eyes will be described with reference to FIGS. FIG. 7 shows the fundus camera head 2 as viewed from above and as viewed from the examiner. A base 701 of the apparatus is provided with a stage 702 for holding the control panel 300 and the optical unit so as to be slidable in the direction of the arrow in the figure by an operating rod 132. Further, the stage 702 is provided with a housing 703 on which an optical system such as the objective lens 103 and the finder 124 is mounted so as to be adjustable in the vertical direction, and the objective 702 with respect to the right eye 704 or the left eye 705 of the subject to be photographed is prepared. The optical axis 705 of the lens can be adjusted. Actual photographing is performed after the examiner operates the operation stem 132 while observing the eye to be examined through the finder 124 and the position is adjusted. When the right eye / left eye is selected, the roller 710 attached to the stage 702 moves up and down according to the step provided on the base 701. When the right eye / left eye is selected, the roller 710 is held in operation. The arm 712 can turn on / off the SW (not shown) to detect whether the stage 712 is at the right eye photographing position or the left eye photographing position. The subsequent operation will be described with reference to FIG. The fundus camera head uses the output of the detector, determines whether the next image to be captured is that of the right eye or that of the left eye, and notifies the change. Upon receiving the notification, the control PC confirms whether the left and right eyes are described in the inspection request in the same manner as in the case of determining the imaging type. A screen for confirmation is displayed 802. The operation branches depending on the examiner's response to this screen, but if an operation other than the inspection request is not desired, it is determined that the operation of the retinal camera head is incorrect, and a warning prompting the correction of the stage position is displayed again or the inspection is performed. The operation 601 returns to the request list display. If the inspection request does not support the left and right eyes, or if the examiner performs an operation other than the inspection request, the control PC prepares for the formation of a new image group for the left and right eyes within the same inspection. Do. Thereafter, when the photographing button on the operation rod 132 of the fundus camera head is operated, actual photographing 804 is performed, and the image data is associated with the device information (including the left and right eye types) collected by the fundus camera head. Sent. In response to this, the control PC registers 805 an image as a new image group. In this embodiment, the fundus camera head transmits left and right eye information prior to shooting, but this confirmation is not essential, and new information is added according to the type of left and right eyes in the device information transmitted after shooting. An image group can be formed and registered in the image group.

  In the above embodiment, the fundus camera is used. However, the same effect can be applied to other ophthalmologic photographing apparatuses such as a photo slit lamp.
