Description

Technical Field

[0001] This invention relates to an image processing apparatus for controlling a lighting device by processing medical images. Background Technology

[0002] In recent years, operating room lighting that can adjust the color and brightness of lighting light from LEDs that emit red, blue, and green light has been known (see Non-Patent Document 1 and Patent Document 1).

[0003] Non-Patent Document 1 discloses the following: by using blue light, which is the complementary color to the red of the organ, blood can be made easier to observe, thereby improving visual recognition.

[0004] Patent Document 1 discloses a system that divides an operating room or examination room into multiple zones based on various tasks involved in the surgery or examination and the desired colors for the surgical personnel, and automatically changes the lighting color for each zone. For example, it discloses that during an endoscopic examination, the lighting behind the endoscope monitor is set to green to make it easier for the surgeon to observe the monitor, while the area where the assistant works is set to red light.

[0006] Patent Document 1: Japanese Patent Publication No. 2010-501218

[0007] Typically, room brightness adjustments are made by nurses or technicians, not doctors, so collaboration with a doctor is necessary.

[0008] Furthermore, in the technology of Patent Document 1, the task of the surgery or examination, or the color desired by the surgeon, needs to be preset in the system. Also, in order to change the color during the surgery, the computer needs to be pre-programmed. Summary of the Invention

[0010] To achieve the above objectives, according to the present invention, a medical image processing apparatus is provided, comprising: an image processing unit that receives medical images and performs preset image processing; a determination unit that determines whether a predetermined state is being held based on the processing result of the image processing unit; and an output unit that, when the determination unit determines that a predetermined state is being held, outputs an instruction to a lighting device connected via a wired or wireless connection to change the light emission state.

[0011] Invention Effects

[0012] According to the present invention, the image processing device determines whether a predetermined state for changing the lighting has been reached by processing medical images and issues an instruction to the lighting device, thereby enabling the automatic change of the lighting in the examination room according to the progress of the examination.

Detailed Implementation

[0024] Hereinafter, embodiments of the present invention will be described using the accompanying drawings.

[0025] The medical image processing apparatus 1 of this embodiment will be described. Figure 1 This is a diagram showing the structure of the medical image processing device 1. Figure 2 This is a diagram illustrating a typical configuration of the X-ray imaging device 100 in an examination room, including the ceiling 80, the patient 10, and the doctor / nurse.

[0026] The medical image processing apparatus 1 of this embodiment is configured to include an image capture unit 22 that receives medical images from a medical image imaging device, an image processing unit 23 that performs preset image processing on the images captured by the image capture unit 22, a determination unit 24, and an output unit 25.

[0027] Medical images can be any type of image captured by a medical imaging device. For example, medical images can be X-ray images (static images) or fluoroscopic images (moving images) captured by an X-ray imaging device 100, images (static and moving images) captured by an endoscope, ultrasound images (static and moving images) captured by an ultrasound imaging device, CT images captured by an X-ray CT device, MRI images captured by an MRI (magnetic resonance imaging) device, etc.

[0028] The determination unit 24 determines whether the image processing result of the image processing unit 23 is that the medical image is in a specified state. The specified state here refers to the situation where the shape, tone, brightness, etc. of the image of the medical device or the image of the organ or blood vessel of the examinee contained in the medical image reach a specified state, or the movement speed or displacement of the medical device or the organ or blood vessel of the examinee contained in the medical image reach a specified value.

[0029] When the determination unit 24 determines that the medical image is in a specified state, the output unit 25 outputs an instruction to the lighting device 40 connected via a wired or wireless connection to change the illumination state. For example, adjusting the emission color or brightness of the lighting device 40 can change the hue or brightness of the indoor lighting, thereby facilitating visual recognition of the medical image displayed on the monitor by doctors, nurses, or other staff. For example, by changing the emission color of the lighting device 40 to blue, the visual recognition of the red color of organs or blood can be improved.

[0030] As for the lighting device 40, it can be any structure as long as it can adjust the color or intensity of the emitted light. For example, it can be a device that uses red LEDs (light-emitting diodes), blue LEDs, and green LEDs as light sources 41 and has a control unit 42 that adjusts the color and intensity of the emitted light by controlling the amount of current supplied to each LED. The control unit 42 has a built-in wired or wireless communication unit and is connected to the output unit 25. For example, short-range wireless communication can be used for wireless communication.

[0031] The image processing apparatus 1 of this embodiment determines whether a predetermined state has been reached by processing medical images and issues instructions to the lighting device. Therefore, it can automatically change the hue or brightness of the examination room lighting according to the progress of the examination. Thus, the lighting can be adjusted by nurses or other staff without the need for instructions from doctors, and there is no need to pre-set the timing of lighting changes. The lighting can be changed at appropriate times, thereby creating an environment where medical images can be easily visually recognized.

[0032] The specific implementation methods are described below.

[0033] Implementation Method 1

[0034] Regarding the medical image processing apparatus 1 of Embodiment 1, as a medical image, it acquires time-series X-ray fluoroscopic images from the X-ray imaging apparatus 100, calculates the moving speed of the device inserted into the subject 10, and changes the emission color to a preset color when the moving speed of the device is less than or exceeds a preset value.

[0035] Here, we will describe the case where the device is an endoscope 31 inserted into the digestive tract or trachea, but it can also be other devices such as a guide wire inserted into a blood vessel, a laparoscope, or a puncture needle inserted into an organ, muscle, spinal cord, or brain.

[0036] The medical image processing device 1 and the illumination device 40 are structured as described above. Figure 1 As stated above.

[0037] The X-ray imaging apparatus 100 includes a top plate 80 for supporting a subject 10, an X-ray irradiation device 11 for irradiating the subject 10 with X-rays, an X-ray detector 12, and an X-ray image generation unit 13. The top plate 80 is supported by a top plate support 81. The X-ray irradiation device 11 is supported relative to the top plate support 81 by a support (not shown).

[0038] An X-ray detector 12 is disposed inside the top plate support 81. The X-ray detector 12 is a planar detector with X-ray detection elements arranged in two dimensions. The X-ray detector 12 detects X-rays that have been irradiated and transmitted from the X-ray irradiation device 11 to the subject 10.

[0039] like Figure 1 As shown, an X-ray image generation unit 13 is connected to the X-ray detector 12. The X-ray image generation unit 13 receives signals from the X-ray detection elements of the X-ray detector 12 that detect and output X-rays, and generates an X-ray image (here, a fluoroscopic image) at a specified frame rate. A fluoroscopic image display monitor 14 is connected to the X-ray image generation unit 13. The fluoroscopic image is displayed on the fluoroscopic image display monitor 14. Furthermore, the output image of the image processing unit 23 of the image processing apparatus 1 can also be displayed on the fluoroscopic image display monitor 14.

[0040] On the other hand, the endoscope device 30 is configured to include an endoscope 31 and a light source device and an image generation unit disposed within the main body of the endoscope device 30. The endoscope 31 has an insertion part 31a that is inserted into the patient, an operating part 31b provided at the base of the insertion part 31a, and a bending part 31c provided within a predetermined range from the front end 31d of the insertion part 31a. By operating the operating part 31b, the bending part 31c performs a bending action. Accompanying this bending action, the front end 31d moves in the desired direction.

[0041] An illumination optical system and an imaging optical system are provided at the front end 31d of the insertion part 31a. The illumination optical system has an illumination lens disposed at the front end of the insertion part 31a, and through the illumination lens, light propagating from the light source device via a light guide is irradiated onto the object being observed. The imaging optical system has an objective lens and an imaging element disposed at the front end of the insertion part 31a. The reflected light from the illumination lens that is irradiated onto the object 10 is incident on the imaging element through the objective lens to form an image. The imaging element is a color imaging sensor capable of acquiring RGB image signals of the three colors R (red), G (green), and B (blue), and captures the reflected image of the object 10 and outputs the image signal. The imaging element is, for example, a CCD (Charge Coupled Device).

[0042] The image signal output from the camera element is input to the image generation unit of the main body of the endoscope device 30. The image generation unit processes the received RGB image signal, generates an endoscope image at a specified frame rate, and displays it on the endoscope image display monitor 16.

[0043] During the examination of the patient 10, the doctor inserts the endoscope 31 of the endoscope device 30 into the digestive tract of the patient 10 from its tip 31d, while simultaneously capturing fluoroscopic images using the X-ray imaging device 100. These fluoroscopic images are then displayed on the fluoroscopic image display monitor 14 at a predetermined frame rate. By observing the image of the endoscope 31 displayed in the fluoroscopic images, the doctor can confirm the position or shape of the tip 31d of the insertion portion 31a of the endoscope 31.

[0044] Furthermore, the doctor can observe images of the digestive tract of the subject 10 captured by the camera element at the tip of the endoscope 31 by observing the endoscope image display monitor 16.

[0045] Next, use Figure 3 The flowchart explains the operation of each part of the image processing device 1.

[0046] Furthermore, the functions of each part of the image processing apparatus 1 can be implemented through software. In this case, the image processing apparatus 1 is composed of a computer or the like, equipped with a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) and memory, and the CPU implements the functions of each part of the image processing apparatus 1 by reading and executing a program stored in memory. Alternatively, part or all of the image processing apparatus 1 can be constructed using hardware. For example, the functions of each part can be implemented by designing circuits using custom ICs such as ASICs (Application Specific Integrated Circuits) or programmable ICs such as FPGAs (Field-Programmable Gate Arrays).

[0047] (Step S101)

[0048] First, the image capturing unit 22 receives the X-ray fluoroscopic image output by the X-ray image generating unit 13 of the X-ray imaging device 100 at a specified frame rate.

[0049] The image processing unit 23 detects the image of the insertion portion 31a of the endoscope 31 contained in the X-ray fluoroscopy image by performing image processing on the X-ray fluoroscopy image, and determines the position of the tip 31d. For example, feature data of the image of the insertion portion 31a of the endoscope 31 in the X-ray fluoroscopy image can be collected in advance using machine learning or the like, and pattern matched with the feature data of the X-ray fluoroscopy image captured by the image capturing unit 22, to extract the image of the endoscope 31 from the X-ray fluoroscopy image and determine the position of the tip 31d of the endoscope 31.

[0050] For each frame of the X-ray fluoroscopic image captured by the image capturing unit 22, the image processing unit 23 detects the position of the tip 31d of the endoscope 31, calculates the amount of movement of the tip 31d between frames, and divides it by the time interval between frames to calculate the current travel speed (movement speed) of the tip 31d of the endoscope 31. Alternatively, the amount of movement between frames can be directly used as the travel speed (movement amount / frame).

[0051] (Steps S102, S103)

[0052] The determination unit 24 determines whether the movement speed of the endoscope 31 is below a preset value (e.g., 5 cm / frame). When the movement speed is below the preset value, it indicates that the doctor is spending time concentrating on observing the endoscopic image displayed on the endoscope image display monitor 16 and making a diagnosis. Therefore, in order to enable the doctor to observe the endoscope image display monitor 16 more clearly by reducing the brightness of the illumination device 40 or changing the light emission color to a preset color (in this case, blue), the process proceeds to step S103 (step S102).

[0053] In step S103, the output unit 25 sends an instruction to the lighting device 40 via wired or wireless communication to reduce the brightness of the light or change the color of the light to a preset color.

[0054] The control unit 42 of the lighting device 40 receives an instruction from the output unit 25 to reduce the current supplied to the red LED, blue LED and green LED of the light source 41 to reduce the light brightness, or to reduce or stop the current supplied to the red LED and green LED to change the light color to the blue light emitted by the blue LED, and proceeds to step S105 (step S103).

[0055] On the other hand, if the travel speed is greater than a preset value, proceed to step S104.

[0056] (Step S104)

[0057] In step S104, in order to maintain the lighting state, the output unit 25 does not send an instruction to the lighting device 40, and directly proceeds to step S105.

[0058] (Step S105)

[0059] The determination unit 24 determines whether the inspection is complete. If it is not complete, it returns to step S101. If the inspection is complete, it proceeds to step S106.

[0060] As a method for determining the end of the inspection by the determination unit 24, for example, the inspection can be determined to be over when the output of an image from at least one of the X-ray image generation unit 13 of the X-ray imaging device 100 and the endoscope device 30 has ended. Furthermore, the inspection can be determined to be over when the operator instructs the inspection to be over via an operation unit (not shown) provided on the image processing device 1.

[0061] (Step S106)

[0062] In step S106, in order to restore the lighting state, the output unit 25 sends an instruction to the lighting device 40 to restore the light brightness and light color to their original state, and then ends.

[0063] In addition, between steps S103 and S104, the endoscope's travel speed can be calculated again in the same way as in steps S101 and S102, and the illumination can be restored if it exceeds the preset value.

[0064] In this embodiment, when performing examinations / treatments using the combined X-ray imaging device 100 and endoscope device 30 (e.g., endoscopic retrograde cholangiopancreatography (ERCP), the lighting in the examination room can be automatically adjusted according to the progress of the examination. This allows the physician to improve the visual clarity of the images from the endoscope 31 without needing to communicate with surrounding staff. Therefore, the physician can focus on the operation of the endoscope.

[0065] Implementation Method 2

[0066] The medical image processing apparatus 1 of Embodiment 2 will be described.

[0067] Regarding the medical image processing apparatus 1 of Embodiment 2, as a medical image, a time-series X-ray fluoroscopic image is captured from the X-ray imaging apparatus 100, and the image processing unit 23 detects the shape of the image of the device (endoscope 31) inserted into the subject 10. The determination unit 24 determines whether the shape of the device has become a predetermined shape. If the device has become a predetermined shape, an instruction is output to the illumination device 40 to change the emission color to a preset color.

[0068] The device is an endoscope 31, and the aforementioned specified shape refers to, for example, Figure 4As shown in the schematic diagram of the fluoroscopic image, the shape in which the doctor protrudes the instrument 35 from the tip 31d of the endoscope 31. If the instrument 35 protrudes from the endoscope 31, it is considered to have reached the prescribed shape regardless of the degree of curvature or the length of protrusion of the instrument 35.

[0069] In addition, the treatment device 35 protruding from the tip 31d of the endoscope 31 can be any device, such as a guide wire, catheter, electrosurgical scalpel, etc.

[0070] The image processing unit 23 and the determination unit 24 perform pattern matching by using feature quantities from machine learning based on X-ray fluoroscopic images to extract images of the shapes protruding from the tip of the endoscope 31 of these treatment instruments 35, and then make a determination. Therefore, for each treatment instrument 35 that may protrude from the tip 31d of the endoscope 31, the feature quantities from machine learning are calculated in advance and stored in the memory within the image processing device 1.

[0071] The structure of the image processing apparatus 1 in Embodiment 2 is the same as that in Embodiment 1, so the description is omitted.

[0072] use Figure 5 The flowchart explains the operation of each part of the image processing apparatus 1. Additionally, regarding the implementation method 1... Figure 3 For actions that are the same as those in the flowchart, the same step numbers will be labeled and a brief explanation will be given.

[0073] (Step S201)

[0074] First, the image capturing unit 22 receives the X-ray fluoroscopic image output by the X-ray image generating unit 13 of the X-ray imaging device 100 at a specified frame rate.

[0075] The image processing unit 23 detects the image of the insertion portion 31a of the endoscope 31 contained in the X-ray fluoroscopy image by performing image processing on the X-ray fluoroscopy image, and determines the shape of the endoscope 31 containing the treatment instrument 35. For example, feature data of the image of the insertion portion 31a of the endoscope 31 in the X-ray fluoroscopy image can be collected in advance using machine learning or the like, and pattern matched with the feature data of the X-ray fluoroscopy image captured by the image capturing unit 22, to extract the image of the endoscope 31 from the X-ray fluoroscopy image and determine the shape of the endoscope 31.

[0076] (Steps S202, S103)

[0077] The determination unit 24 determines whether the treatment instrument 35 has become a shape protruding from the tip of the endoscope 31. The situation where the treatment instrument 35 has become a protruding shape indicates that the doctor is about to perform some kind of treatment on the patient 10, such as tissue removal. Therefore, in order to enable the doctor to observe the endoscope image display monitor 16 more clearly by reducing the brightness of the illumination device 40 or changing the light emission color to a preset color (blue in this case), the process proceeds to step S103 (step S202).

[0078] In step S103, the output unit 25 sends an instruction to the lighting device 40 via wired or wireless communication to reduce the brightness of the light or change the color of the light to a preset color. The control unit 42 of the lighting device 40 receives the instruction from the output unit 25, reduces the brightness of the light or changes the color of the light to blue light, and proceeds to step S105 (step S103).

[0079] On the other hand, if the endoscope 31 does not change to the prescribed shape (the treatment device 35 does not protrude), proceed to step S104.

[0080] (Step S104)

[0081] In step S104, in order to maintain the lighting state, the output unit 25 does not send an instruction to the lighting device 40, and directly proceeds to step S105.

[0082] (Step S105)

[0083] The determination unit 24 determines whether the inspection is complete. If it is not complete, it returns to step S101. If the inspection is complete, it proceeds to step S106.

[0084] (Step S106)

[0085] In step S106, in order to restore the lighting state, the output unit 25 sends an instruction to the lighting device 40 to restore the light brightness and light color to their original state, and then ends.

[0086] According to Embodiment 2, when the X-ray perspective is used to detect the protrusion of the guide wire or other treatment instrument 35 from the front end 31d of the endoscope 31, the illumination can be changed when the guide wire or other treatment instrument 35 protrudes from the endoscope 31, since visual recognition is important.

[0087] Implementation Method 3

[0088] The medical image processing apparatus 1 of Embodiment 3 will be described.

[0089] The medical image processing apparatus 1 of Embodiment 3 uses endoscopic images as medical images. The image processing unit 23 calculates the tonal components of the endoscopic image. When the red component value (the degree of red tone) exceeds a threshold, it is necessary to emphasize the red tone, so the illumination is changed.

[0090] The structure of the image processing device 1 in Embodiment 3 is the same as that in Embodiment 1. However, in this Embodiment 3, since X-ray fluoroscopic images are not used, X-ray fluoroscopic images are not captured from the X-ray imaging device 100.

[0091] use Figure 6 The flowchart explains the operation of each part of the image processing apparatus 1. Additionally, regarding the implementation method 1... Figure 3 For actions that are the same as those in the flowchart, the same step numbers will be labeled and a brief explanation will be given.

[0092] (Step S301)

[0093] First, the image capturing unit 22 receives the endoscope image output by the endoscope device 30 at a specified frame rate.

[0094] The image processing unit 23 calculates the hue composition of the endoscope image by performing image processing on the endoscope image.

[0095] (Steps S302, S103)

[0096] The determination unit 24 determines whether the red tint component (degree of red tint) of the endoscope 31 exceeds a preset value. If the red tint component (degree of red tint) exceeds the preset value, since it is necessary to emphasize the red tint, the unit proceeds to step S103 in order to reduce the brightness of the illumination device 40 or change the emission color to a preset color (blue in this case).

[0097] In step S103, the output unit 25 sends an instruction to the lighting device 40 via wired or wireless communication to reduce the light intensity or change the light color to a preset color, and then returns to step S301. Thereupon, the control unit 42 of the lighting device 40 receives the instruction from the output unit 25 and reduces the light intensity or changes the light color to blue light.

[0098] On the other hand, if the red hue component (the degree of red hue) of the endoscopic image does not exceed a preset value, proceed to step S104.

[0099] (Step S104)

[0100] In step S104, in order to maintain the lighting state, the output unit 25 does not send an instruction to the lighting device 40, but returns directly to step S301.

[0101] Implementation Method 4

[0102] The medical image processing apparatus 1 of Embodiment 4 will be described.

[0103] In embodiment 4, the medical image processing device 1 reaches the target location 50 (reference) at the tip 31d of the endoscope 31. Figure 7 Change indoor lighting in the following circumstances.

[0104] The structure of the image processing device 1 in Embodiment 3 is the same as that in Embodiment 1. However, in this Embodiment 3, since X-ray fluoroscopic images are not used, X-ray fluoroscopic images are not captured from the X-ray imaging device 100.

[0105] use Figure 8 The flowchart explains the operation of each part of the image processing apparatus 1. Additionally, regarding the implementation method 1... Figure 3 For actions that are the same as those in the flowchart, the same step numbers will be labeled and a brief explanation will be given.

[0106] (Step S401)

[0107] First, the image capturing unit 22 receives the X-ray fluoroscopic image output by the X-ray image generating unit 13 of the X-ray imaging device 100 at a specified frame rate.

[0108] The image processing device 1 receives the target location 50 specified by the doctor in the received fluoroscopic image via an input unit such as a mouse or touch panel.

[0109] The image processing unit 23 detects the image of the insertion part 31a of the endoscope 31 contained in the X-ray fluoroscopic image by performing image processing on the X-ray fluoroscopic image, and determines the position of the front end 31d.

[0110] (Step S402)

[0111] The determination unit 24 determines whether the position of the tip 31d of the endoscope 31 has reached the target location 50 received from the doctor.

[0112] If the tip 31d of the endoscope 31 reaches the target location 50, proceed to step S103. On the other hand, if the travel speed is greater than a preset value, proceed to step S104.

[0113] (Step S103)

[0114] In step S103, the output unit 25 sends an instruction to the lighting device 40 via wired or wireless communication to reduce the light emission brightness or change the light emission color to a preset color, and then returns to step S401.

[0115] Therefore, the illumination device 40 reduces the brightness of the light or changes the color of the light to a preset color (blue in this case), so that the doctor can observe the endoscopic image display monitor 16 more clearly.

[0116] (Step S104)

[0117] In step S104, in order to maintain the lighting state, the output unit 25 does not send an instruction to the lighting device 40, but returns directly to step S401.

[0118] Implementation Method 5

[0119] In embodiments 1 to 4 described above, in step S103, by reducing the brightness of the light source 41 of the illumination device 40 or changing the light emission color to a preset color (here, the blue tint is increased), the doctor can observe the endoscopic image display monitor 16 more clearly. At this time, if the brightness or color of the illumination device 40 changes instantaneously, the eye response of the doctor or other operator will not be able to keep up.

[0120] Therefore, in embodiment 5, the output unit 25 controls the speed at which the light emission state of the lighting device 40 is changed to below a preset speed, and sends an instruction to the control unit 42 of the lighting device 40 so that it gradually changes the light rather than drastically. For example, as Figure 9 As shown in (a) and (b) in the diagram, an instruction is sent to gradually change the luminance or blue component. Figure 9 The time shifts of the luminance or hue components in (a) and (b) are pre-stored as a table in the memory constituting the image processing apparatus 1. The output unit 25 reads the time shifts of the luminance or hue components from the table in the memory and gradually changes the values ​​of the luminance or hue components sent to the illumination device 40.

[0121] Furthermore, in embodiments 1 to 4, such as Figure 3 , Figure 5 , Figure 6 , Figure 8 As shown in the process, during the continuous inspection, it is determined whether a specified state has been reached, and the cycle of lighting change is repeated. Preferably, this is done after changing the luminance or hue once in step S103, such as... Figure 9 As shown in (c), a lighting control pause period is set for a certain time (e.g., about 3 seconds) during which the brightness or hue of the light emission does not change. During the lighting control pause period, lighting control is not performed even when step S103 is entered.

[0122] In embodiments 1 to 4, by controlling the lighting as in embodiment 5, the lighting can be controlled taking into account the response speed of the eyes of doctors and others, thus creating an environment in which medical images can be easily visually recognized.
