Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an OCT endoscope system, a probe positioning method, an electronic device, and a storage medium. Background Technology

[0002] Cervical cancer, one of the most common gynecological malignancies, relies heavily on histopathological biopsy as a key step in its screening and diagnosis, considered the "gold standard" for confirming cervical cancer. However, due to its invasive nature, biopsies typically collect no more than four samples at a time, and the sampling location relies heavily on colposcopy results. Given that colposcopy is essentially a visual assessment, its accuracy in identifying early precancerous lesions occurring under the cervical epithelium is limited. Furthermore, experienced colposcopy practitioners are relatively scarce. These factors combined contribute to a high misdiagnosis rate during biopsies, potentially missing the true lesion or leading to unnecessary overtreatment and wasted medical resources due to collecting too many negative samples.

[0003] In recent years, optical coherence tomography (OCT), as a non-invasive imaging technique, has shown great potential in the field of cervical cancer screening. OCT technology can provide high-resolution images of cells and tissues within a depth of approximately 2 millimeters below the surface of the cervix, which helps to more accurately identify and locate lesions, thereby improving the accuracy and efficiency of biopsies and reducing the risk of missed diagnoses.

[0004] While OCT technology significantly improves the identification of lesions, precise location of the examination site is still necessary in practical applications to ensure that biopsy doctors can accurately collect samples from the lesion site. Traditional location methods divide the cervical region into 12 clock positions and mark these positions to indicate the lesion area. Considering that the diameter of the human cervix is ​​approximately 2-3 cm, this means that each clock position actually represents a broad area, while the size of an OCT examination or biopsy sample is typically only about 2 mm. Therefore, relying solely on clock positions is insufficient for accurate lesion location identification. To address this issue, using image-based methods to mark lesion locations has become a more ideal alternative, providing more accurate guidance for biopsy sampling.

[0005] When considering how to effectively record OCT examination points, a colposcope seems to be the preferred image recording tool. However, since the colposcope is usually placed at a certain distance outside the body, it may be obstructed by a speculum or the OCT probe during OCT examination, affecting the observation of the probe's position. Furthermore, as independent devices, the colposcope and OCT system are difficult to operate synchronously. Another possible solution is to use a traditional endoscope, but since its working distance generally needs to be maintained at more than 30 mm to accommodate the operation of surgical instruments, mounting its camera at the tip of the OCT probe would hinder comprehensive imaging of the tissue surface. To address these challenges, this invention proposes an innovative design concept: mounting the endoscopic camera at the base of the OCT probe, achieving collaborative operation between the camera and the OCT probe. While acquiring OCT images, this design can record images of the cervical surface and the specific position of the probe, with positioning accuracy reaching the millimeter level, far superior to traditional clock-based position recording methods. Summary of the Invention

[0006] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an OCT endoscope system, probe positioning method, electronic device and storage medium that can accurately determine the location of the target acquisition point of the probe without the need for a colposcope, assist doctors in judging the location of the target acquisition point and avoid missed or repeated acquisition.

[0007] This application provides the following technical solution:

[0008] In a first aspect, embodiments of this application provide an OCT endoscopy system, the OCT endoscopy system comprising:

[0009] OCT scanning probe, wherein the OCT scanning probe has a probe tube;

[0010] At least two image acquisition modules are disposed on the OCT scanning probe and away from the probe tube. Each image acquisition module has a field of view and an acquisition end. The image acquisition module is used to acquire image information of the field of view. The acquisition ends of the at least two image acquisition modules are spaced apart along the circumference of the probe tube, such that all the fields of view of the at least two image acquisition modules cover the peripheral side of the distal end of the probe tube.

[0011] The system includes an image display module and a data processing module. The image acquisition module and the data processing module are electrically connected, and the data processing module and the image display module are also electrically connected. The data processing module is used to convert all the image information acquired by the at least two image acquisition modules into panoramic image information around the probe tube. The image display module is used to display the panoramic image information.

[0012] In some embodiments of the first aspect, the OCT scanning probe further includes:

[0013] The probe holder and the distal end of the probe tube are detachably connected, and the image acquisition module is located at the end of the probe holder near the probe tube.

[0014] In some embodiments of the first aspect, the probe tube includes at least two tube segments connected in sequence, wherein in any two adjacent tube segments, the outer diameter of the tube segment facing away from the proximal end is smaller than the outer diameter of the tube segment closer to the proximal end.

[0015] In some embodiments of the first aspect, the center line of the field of view is tangent to the edge of the distal end face of the probe tube.

[0016] In some embodiments of the first aspect, the image acquisition module includes a circuit board, a camera module, and at least one light source module. The camera module and at least one light source module are both disposed on the component side of the circuit board. The camera module and at least one light source module are both electrically connected to the circuit board. The circuit board is electrically connected to the data processing module, and the circuit board is disposed on the OCT scanning probe.

[0017] In some embodiments of the first aspect, the OCT scanning probe further includes a probe base connected to the proximal end of the probe tube. The probe base has a support portion at one end near the probe tube. The end face of the support portion opposite to the probe base is a mounting end face. The mounting end face abuts against the soldering surface of the circuit board. The included angle between the mounting end face and the axis of the probe tube is configured such that the center line of the field of view is tangent to the edge of the distal end face of the probe tube.

[0018] In some embodiments of the first aspect, the OCT scanning probe further includes a cover plate having a light source window and a lens window. The cover plate and the probe holder are connected to one end near the probe tube, such that a mounting cavity is formed between the cover plate and the probe holder. The camera module and the light source module are both located in the mounting cavity. Each camera module corresponds to the lens window, and each light source module corresponds to the light source window.

[0019] In some embodiments of the first aspect, the number of the support portions is multiple, there is a gap between adjacent support portions, and there is a gap between the circuit board and the mounting end.

[0020] Secondly, this application also provides a probe positioning method, applied to the OCT endoscope system described in any of the above embodiments, the probe positioning method comprising:

[0021] Acquire multiple image information from the distal periphery of the probe tube;

[0022] The panoramic image information of the distal end of the probe tube is constructed using the multiple image information.

[0023] The location information of the central blind zone in the panoramic image information is obtained, and the central blind zone is set as the target acquisition point of the probe.

[0024] Thirdly, this application also provides an electronic device, comprising:

[0025] Memory, used to store computer programs;

[0026] A processor is used to execute the computer program to implement the probe positioning method as described in the above embodiments.

[0027] Fourthly, this application also provides a computer-readable storage medium for storing a computer program, which, when executed by a processor, implements the probe positioning method as described in the above embodiments.

[0028] The embodiments of this application have the following advantages:

[0029] This application provides a probe used in conjunction with a vaginal speculum. After the vagina is opened by the speculum, the distal end of the probe tube is inserted into the cervix, with the distal end of the probe tube contacting the target acquisition point. Due to the limited distribution of multiple image acquisition modules, the field of view of each module is partially obstructed by the probe tube, resulting in blind spots in the images captured by each module. However, the combination of images acquired by all modules eliminates the blind spots outside the distal end face of a single module, allowing for the acquisition of a panoramic image of the probe tube's periphery. The central blind spot obstructed by the distal end face of the probe tube in this panoramic image is the optical scanning position of the OCT scanning probe. Therefore, the target scanning point can be precisely controlled by adjusting the position of the central blind spot in the panoramic image. When used with a colposcope, a complete image of the cervical surface is captured using the colposcope and then imported into the OCT cervical detection device. After software processing, the probe's acquisition position is simultaneously displayed on the corresponding acquisition point on the complete cervical image captured by the colposcope.

[0030] Clearly, this probe can also acquire data directly without the aid of an external colposcope. This simplifies the procedure and reduces the difficulty and error for doctors. In gynecological examinations, this probe can be used for high-precision imaging and localization of the cervix, helping doctors to more accurately determine the location of lesions. Of course, this design can also be applied to other endoscopic examination scenarios requiring high-precision imaging and localization. Therefore, this application achieves high-precision localization and high-quality imaging of the target acquisition point, significantly improving the accuracy and reliability of OCT examinations and providing strong support for clinical diagnosis.

[0054] Among related technologies, OCT (Optical Coherence Tomography) is a high-resolution, non-invasive optical imaging technique. It uses low-coherence near-infrared light to illuminate biological tissue, and by interferometric measurement of the scattered light signals, it obtains two-dimensional cross-sectional images or three-dimensional reconstructed images of the biological tissue with micron-level resolution. In OCT, image contrast is generated by the optical refractive index mismatch of the tissue structure, requiring no exogenous contrast agents, and the imaging depth within the tissue is approximately 2mm to 3mm. OCT is well-suited for surface applications, such as retinal imaging. With the development of OCT probe catheter technology in recent years, OCT is increasingly being used in endoscopic fields, including cardiovascular, digestive tract, lung, larynx, and genitourinary systems. To apply these optical detection technologies to the screening and diagnosis of various diseases, a crucial step is transmitting and focusing the light beam onto the target tissue area and collecting the returned light signal, transmitting it to the acquisition device. The quality of beam transmission and focusing directly determines important indicators such as the resolution and signal-to-noise ratio of the optical image. To achieve this goal, a probe for gynecological examinations has emerged for cervical detection.

[0055] It is important to note that biopsy remains the gold standard for cervical examination. A crucial role of OCT in clinical use is to accurately identify suspicious areas before biopsy, providing guidance for the procedure, improving accuracy, and reducing the rate of missed diagnoses. However, OCT examinations require the assistance of a colposcope for illumination and imaging of the cervix. Typically, the location of the target imaging point is determined based on the doctor's experience, and differences may occur between doctors with varying experience levels. Furthermore, the OCT probe partially obstructs the colposcope during imaging, potentially leading to inaccurate target imaging point location.

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, to solve the above-mentioned technical problems, this application provides an OCT endoscopy system. The OCT endoscopy system includes an OCT scanning probe 100, at least two image acquisition modules 200, an image display module, and a data processing module. The OCT scanning probe 100 has a probe tube 110. The at least two image acquisition modules 200 are disposed on the OCT scanning probe 100 and away from the probe tube 110. Each image acquisition module 200 has a field of view and an acquisition end. The image acquisition modules 200 are used to acquire image information of the field of view. The acquisition ends of the at least two image acquisition modules 200 are spaced apart along the circumference of the probe tube 110, so that all the fields of view of the at least two image acquisition modules 200 cover the periphery of the distal end 111 of the probe tube 110. The image acquisition modules 200 and the data processing module are electrically connected, and the data processing module and the image display module are electrically connected. The data processing module is used to convert all the image information acquired by the at least two image acquisition modules 200 into panoramic image information 400 of the periphery of the probe tube 110. The image display module is used to display the panoramic image information 400.

[0057] To address the aforementioned technical problems, this application provides an innovative OCT endoscopy system design, particularly suitable for OCT (Optical Coherence Tomography) to improve positioning accuracy and imaging quality during examinations of areas such as the cervix. The OCT scanning probe 100 includes a probe tube 110, which is the main structural component of the probe. The distal end 111 of the probe tube 110 is inserted into the cervix and contacts the target detection point for optical scanning.

[0058] Image acquisition modules 200 are used to assist OCT scanning probe 100. At least two image acquisition modules 200 are capable of acquiring image information from the periphery of the distal end 111 of probe tube 110. For example, at least two image acquisition modules 200 are evenly distributed along the circumference of probe tube 110 to ensure that images are acquired from multiple angles.

[0059] It should be noted that the image acquisition modules 200 are all mounted on the OCT scanning probe 100 and close to the proximal end 112 of the probe tube 110 to avoid increasing the size of the probe tube 110 and to facilitate observation by the staff. In addition, the distal end 111 of the probe tube 110 can block part of the field of view, laying the groundwork for the subsequent formation of the central blind zone 410.

[0060] Furthermore, it is ensured that a single image acquisition module 200 can capture partial image information around the distal end 111 of the probe tube 110. Clearly, by distributing at least two image acquisition modules 200 around the periphery of the probe tube 110, the distal end 111 of the probe tube 110 is within the field of view of all image acquisition modules 200. This ensures that image information around the periphery of the probe tube 110 is acquired from different angles. By acquiring multiple images, the positional information of the distal end 111 of the probe tube 110 is obtained, improving the accuracy of the positioning of the distal end 111 of the probe tube 110.

[0061] For example, in this embodiment, the number of image acquisition modules 200 is two. Of course, in other embodiments, the number of image acquisition modules 200 may be three, four, five, six, seven, or eight, etc.

[0062] The data processing module is used to convert all image information acquired by at least two image acquisition modules 200 into panoramic image information 400 around the probe tube 110. The acquired panoramic image information 400 has a central blind zone 410 in the middle, which is formed by the end face of the distal end 111 of the probe tube 110.

[0063] For example, the data processing module includes an image processing unit, a data transmission unit, and a control unit. The image processing unit is responsible for processing multiple image information captured by the image acquisition module 200 to generate panoramic image information 400 around the probe tube 110. The data transmission unit is responsible for transmitting the processed image information to the image display module. The control unit is responsible for coordinating the work of each module to ensure the normal operation of the system.

[0064] The image display module is used to display panoramic image information 400 for doctors to observe, thereby obtaining the position information of the central blind zone 410. By adjusting the position information of the central blind zone 410, the position of the target acquisition point at the distal end 111 of the probe tube 110 can be precisely controlled. For example, the image display module includes a display, such as a tablet, computer monitor, and television.

[0065] During operation, it is used in conjunction with a vaginal speculum. After the vagina is opened with the speculum, the distal end 111 of the probe tube 110 is inserted into the cervix, and the end face of the distal end 111 of the probe tube 110 is placed against the target acquisition point. Due to the limited distribution of the multiple image acquisition modules 200, the field of view of each image acquisition module 200 is partially blocked by the probe tube 110, resulting in blind spots in the images captured by each image acquisition module 200. However, the combination of the image information acquired by all the image acquisition modules 200 eliminates the portion of the blind spot outside the end face of the distal end 111 in the image information captured by a single image acquisition module 200, enabling the acquisition of panoramic image information 400 around the probe tube 110. The central blind spot in the panoramic image information 400, which is blocked by the end face of the distal end 111 of the probe tube 110, is the optical scanning position of the OCT scanning probe 100. Therefore, the target scanning point can be precisely controlled by controlling the position of the central blind spot in the panoramic image information 400.

[0066] Clearly, this application eliminates the need for an external colposcope, simplifying the procedure and reducing the difficulty and potential error for doctors. In gynecological examinations, this probe can be used for high-precision imaging and localization of the cervix, helping doctors more accurately determine the location of lesions. Of course, this design can also be applied to other endoscopic examination scenarios requiring high-precision imaging and localization. Therefore, this application achieves high-precision localization and high-quality imaging of the target acquisition point, significantly improving the accuracy and reliability of OCT examinations and providing strong support for clinical diagnosis.

[0067] like Figure 1 and Figure 2 As shown, in some embodiments, the OCT scanning probe 100 also includes a probe base 120, the probe base 120 and the distal end 111 of the probe tube 110 are detachably connected, and the image acquisition module 200 is disposed at the end of the probe base 120 near the probe tube 110.

[0068] These embodiments further clarify some specific implementation details of the OCT scanning probe 100, particularly regarding the design of the probe mount 120. The following is a detailed description:

[0069] The probe tube 110 is the main structural component of the OCT scanning probe 100, used for insertion into the body for imaging. The probe holder 120 is connected to the distal end 111 of the probe tube 110, facilitating the doctor's grip and operation. The image acquisition module 200 is located at the end of the probe holder 120 near the probe tube 110.

[0070] This obviously makes the entire probe structure more compact and integrated. The image acquisition module 200 is located at one end of the probe holder 120 near the probe tube 110, ensuring that the center line 221 of the field of view is tangent to the edge of the distal end 111 of the probe tube 110; and avoiding occupying the space at the front end of the probe tube 110.

[0071] Furthermore, the probe tube 110 and the probe holder 120 are typically detachably connected. The probe holder 120 integrates the camera module 220 and the light source module 210, which facilitates the subsequent disassembly and assembly of the probe tube 110.

[0072] It should be noted that during gynecological cervical examinations, this probe can be used for high-precision imaging and positioning of the cervix, helping doctors to more accurately determine the location of lesions. Furthermore, since the patient's vagina has been pre-dilated using a speculum, it will not interfere with the image acquisition module 200.

[0073] like Figure 2 As shown, in some embodiments, the probe tube 110 includes at least two tube segments connected in sequence, and in any two adjacent tube segments, the outer diameter of the tube segment away from the proximal end 112 is smaller than the outer diameter of the tube segment closer to the proximal end 112.

[0074] In these embodiments, the structure of the OCT scanning probe 100 has been further optimized to make it more suitable for use in confined physiological environments. The probe tube 110 includes at least two segments connected sequentially to form a whole. Obviously, this design makes it easier for the probe tube 110 to enter confined physiological environments, such as the cervix, reducing the risk of tissue damage.

[0075] Furthermore, the gradually decreasing outer diameter design reduces friction and damage to tissues, improving patient comfort and safety.

[0076] Furthermore, the miniaturization of the remote 111 facilitates the probe's accurate positioning of the target acquisition point.

[0077] For example, the outer diameter of the probe tube 110 gradually decreases in the axial direction. For instance, the probe tube 110 is frustum-shaped.

[0078] like Figure 5 As shown, in some embodiments, the center line 221 of the field of view is tangent to the edge of the distal end 111 of the probe tube 110.

[0079] In these embodiments, when the center line 221 of the field of view of the image acquisition module 200 is tangent to the edge of the end face of the distal end 111 of the probe tube 110, the outer half of the image can be seen during acquisition, except for the area covered by the end face of the distal end 111 of the probe tube 110. After the image information acquired by multiple image acquisition modules 200 is synthesized and processed, the circular shadow area not seen by the image acquisition module 200 is the acquisition window position of the distal end 111 of the probe tube 110 (i.e., the central blind zone 410), and the position of the target acquisition point can be obtained.

[0080] like Figure 3 As shown, in some embodiments, the image acquisition module 200 includes a circuit board 230, a camera module 220, and at least one light source module 210. The camera module 220 and at least one light source module 210 are both disposed on the component side of the circuit board 230. The camera module 220 and at least one light source module 210 are both electrically connected to the circuit board 230. The circuit board 230 is electrically connected to the data processing module, and the circuit board 230 is disposed on the OCT scanning probe 100.

[0081] In these embodiments, the circuit board 230, camera module 220, and at least one light source module 210 are integrated. The light source module 210 and camera module 220 share a single circuit board 230, enabling integration, reducing probe size, and lowering costs. Furthermore, the illumination direction of the light source module 210 can be adjusted simultaneously by adjusting the orientation of the camera module 220.

[0082] Of course, in other embodiments, the light source module 210 and the camera module 220 may also be connected to different circuit boards 230 respectively.

[0083] For example, there is one light source module 210, which is arranged in a ring shape. The probe tube 110 is located inside the light source module 210, and the light source module 210 is also located at the end of the probe holder 120 near the probe tube 110, ensuring that the illumination area covers the periphery of the distal end 111 of the probe tube 110. Of course, in other embodiments, there are multiple light source modules 210, which are evenly distributed along the circumference of the probe tube 110 to provide uniform illumination. Of course, there is no specific limitation here, as long as it can achieve peripheral illumination of the distal end 111 of the probe tube 110.

[0084] For example, the light source module 210 includes LED beads, which are divergent light sources, such that the distal end 111 of the probe tube 110 is located within the illumination range of the LED beads.

[0085] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, the OCT scanning probe 100 further includes a probe base 120, which is connected to the proximal end 112 of the probe tube 110. The end of the probe base 120 near the probe tube 110 has a support portion 240. The end face of the support portion 240 away from the probe base 120 is a mounting end 121 face. The mounting end 121 face abuts against the soldering surface of the circuit board 230. The included angle between the mounting end 121 face and the axis of the probe tube 110 is configured such that the center line 221 of the field of view and the edge of the distal end 111 face of the probe tube 110 are tangent.

[0086] In these embodiments, the specific structure of the OCT scanning probe 100 is further refined to ensure that the center line 221 of the field of view is tangent to the edge of the distal end 111 of the probe tube 110, thereby improving the accuracy and quality of imaging. The camera module 220 is mounted on the component surface of the circuit board 230 and electrically connected to the circuit board 230. The circuit board 230 contains the electronic components required for imaging, is electrically connected to the camera module 220, and processes imaging data. One end of the support portion 240 is connected to the probe holder, and the other end is connected to the circuit board 230. The end face of the support portion 240 connected to the circuit board 230 is the mounting end 121 face, which abuts against the soldering surface of the circuit board 230. The angle between the mounting end 121 face and the axis of the probe tube 110 is configured to ensure that the center line 221 of the field of view is tangent to the edge of the distal end 111 of the probe tube 110. In other words, by controlling the tilt angle of the mounting end 121 face, the extension direction of the center line 221 of the field of view can be adjusted.

[0087] For example, the support 240 and the probe mount 120 are integrated. Of course, they can also be configured to be detachably connected.

[0088] like Figure 1 and Figure 2 As shown, in some embodiments, the OCT scanning probe 100 further includes a cover plate 130, which has a light source window 131 and a lens window 132. The cover plate 130 and the probe holder 120 are connected to one end near the probe tube 110, so that an installation cavity is formed between the cover plate 130 and the probe holder. The camera module 220 and the light source module 210 are both located in the installation cavity. Each camera module 220 has a corresponding lens window 132, and each light source module 210 has a corresponding light source window 131.

[0089] In these embodiments, the structure of the probe holder 120 is further refined to ensure a reasonable layout and protection of the camera module 220 and the light source module 210 on the probe holder 120. The probe holder 120 has a mounting end 121 for fixing and supporting the camera module 220 and the light source module 210. One end of the support portion 240 is connected to the mounting end 121, and the other end is connected to the circuit board 230 to ensure the stability of the camera module 220.

[0090] The cover plate 130 has at least two light source windows 131, which are configured one-to-one with the light source module 210 to ensure that light can pass through smoothly. In addition, the cover plate 130 has at least two lens windows 132, which are configured one-to-one with the lens group of the camera module 220 to ensure that imaging light can pass through smoothly.

[0091] The cover plate 130 is connected to the mounting end 121, together forming a mounting cavity. The camera module 220 and the light source module 210 are located in the mounting cavity to avoid contamination during use and to facilitate cleaning.

[0092] For example, in this embodiment, the cover plate 130 and the mounting end 121 are detachably connected. For instance, the cover plate 130 and the mounting end 121 are fastened together. Alternatively, the cover plate 130 and the mounting end 121 are connected by screws, etc.

[0093] For example, the lens window 132 and the light source window 131 are formed by a transparent area on the cover plate 130. Optionally, the cover plate 130 is provided with an opening, and a transparent plate is sealed on the opening to form a transparent area.

[0094] like Figure 3 and Figure 4 As shown, in some embodiments, there are multiple support portions 240, with gaps between adjacent support portions 240, and gaps between the circuit board 230 and the mounting end 121.

[0095] In these embodiments, a reasonable layout and ventilation are ensured between the circuit board 230 and the mounting end 121.

[0096] There are multiple support portions 240, evenly distributed along the circumference of the probe tube 110. Gaps exist between adjacent support portions 240 to ensure airflow and aid in heat dissipation. It is sufficient that the mounting ends 121 of the multiple support portions 240 are on the same plane.

[0097] A gap exists between the circuit board 230 and the mounting end 121 to ensure airflow and aid in heat dissipation. Despite the gap, the design of the support portion 240 ensures the stability of the circuit board 230 and prevents it from shaking during operation.

[0098] For example, the support portion 240 is columnar. Of course, in other embodiments, it can also be a hollow structure, etc.

[0099] Clearly, the gaps between the multiple support sections 240 and between the circuit board 230 and the mounting end 121 ensure airflow and heat dissipation, thereby improving the stability and service life of the equipment.

[0100] like Figure 8 As shown, in some embodiments, this application also provides a probe positioning method applied to the OCT endoscope system described in the above embodiments. The probe positioning method includes the following steps:

[0101] S100: Acquire multiple image information around the distal end 111 of the probe tube 110;

[0102] In these embodiments, multiple camera modules 220 acquire image information from different angles around the distal end 111 of the probe tube 110. The camera modules 220 transmit the acquired image information to the data processing module via the circuit board 230.

[0103] S200: Construct panoramic image information 400 of the distal end 111 of the probe tube 110 using the multiple image information;

[0104] In these embodiments, the data processing module stitches together the image information acquired by multiple camera modules 220 to generate panoramic image information 400 of the far end 111 of the probe tube 110. The stitched image is then processed to ensure image continuity and clarity.

[0105] S300: Obtain the position information of the central blind zone 410 in the panoramic image information 400, and set the central blind zone 410 as the target acquisition point of the probe.

[0106] In these embodiments, the location of the central blind zone 410 is identified in the panoramic image. The central blind zone 410 refers to the area that cannot be directly imaged due to the presence of the probe tube 110. Setting the location of the central blind zone 410 as the target acquisition point of the probe ensures that the acquired image information covers the entire inspection area, avoiding missed or repeated acquisitions.

[0107] In other words, the probe positioning method is applied to the probe described in the above embodiments. By acquiring multiple image information from the periphery of the distal end 111 of the probe tube 110, panoramic image information 400 is constructed, and the location of the target acquisition point is determined.

[0108] For example, the number of imaging modules is two, such as Figure 6 As shown, a panoramic image 400 is synthesized from the image information captured by the two camera modules 220, evenly distributed at the center of the probe tube 110. The gray shaded area in the middle is the central blind zone 410 of the image acquisition module 200, which is blocked by the far end 111 of the probe tube 110. After the image information captured by the two imaging modules is synthesized, the central circle in the figure is the position of the end face of the far end 111 of the probe, which is the position of the probe acquisition point.

[0109] Additionally, a simulation diagram is provided, such as... Figure 10 and Figure 11 As shown, where, Figure 10 Images captured by the two imaging modules respectively. Figure 11 This is an image synthesized from images acquired by the two imaging modules. Clearly, it can accurately locate the probe position.

[0110] For example, the number of imaging modules is four, such as Figure 7 This is a panoramic image 400 synthesized from images captured by four camera modules 220 evenly distributed around the center of the probe tube 110. This method allows for precise positioning of the OCT probe's acquisition point, improving accuracy. During acquisition, simply align the central blind zone 410 in the image with the target acquisition point and attach it; the acquired position is the target acquisition point.

[0111] Of course, in other embodiments, the number of imaging modules may also be three, five, six, etc.
