Description

Technical Field

[0001] The present invention relates to the technical field of optical imaging, and particularly to a medical 3D optical imaging system and method. Background Art

[0002] A medical 3D optical imaging system is an imaging device based on optical principles and technologies, used to obtain three-dimensional structural information of the human body or tissues. Such systems are increasingly widely used in the medical field, especially in the early diagnosis of diseases, surgical planning, real-time monitoring, etc., and have important application prospects;

[0003] Currently, in the medical field, 3D optical imaging technology is widely used in multiple aspects such as disease diagnosis, surgical planning, and monitoring. However, existing medical 3D optical imaging systems usually need to select different types of imaging devices according to different detection requirements. For example, for different parts or different types of tissues, different imaging principles or technologies may be required, such as surface imaging, depth scanning, spectral imaging, etc. Each imaging requirement corresponds to a specific device configuration, which results in hospitals or research institutions needing to be equipped with multiple sets of devices.

[0004] Since the technical requirements of each device are different, relatively independent and specialized spaces are usually required for installation and operation. Especially large medical devices often require additional support facilities such as power supply and cooling systems, which further increases the demand for physical space. This not only increases the space pressure on hospitals or laboratories, but also improves the equipment maintenance cost and management difficulty.

[0005] In addition, due to the need for multiple devices to meet different imaging requirements, the costs of device procurement and maintenance have increased significantly. These factors together have led to a significant increase in the overall cost of medical 3D optical imaging systems, bringing a considerable economic burden to medical institutions. In order to improve the diagnosis and treatment efficiency and reduce costs, how to simplify the device configuration and optimize the device utilization rate has become an urgent problem in the industry.

[0009] In the specific implementation process, both of the two first clamping assemblies include: a first support frame, a first operation groove, two first linear slide tables and two first clamping plates;

[0010] The first support frame is fixedly installed on one side of the mounting frame. The first operation groove is opened at the center of the upper end of the first support frame. Two first linear modules are respectively installed on both sides of the front end of the mounting frame.

[0011] In the specific implementation process, the replacement structure includes: two sliding grooves, a moving plate, a third motor, an electric push rod, a mounting column, a number of storage racks and a number of second clamping assemblies;

[0012] Both of the two sliding grooves are installed on the upper end of the bottom plate. Both ends of the moving plate are respectively movably embedded in the two sliding grooves. The third motor is fixedly installed on the upper end of the moving plate. One end of the electric push rod is fixedly installed on one side of the upper end of the bottom plate, and the telescopic end is connected to one side of the moving plate. The mounting column is fixedly installed on the driving end of the third motor. A number of storage racks are respectively installed on the side wall of the mounting column.

[0013] In the specific implementation process, a number of the second clamping assemblies all include: a second support frame, a second operation groove, two second linear slide tables and two second clamping plates;

[0014] The second support frame is fixedly installed on one side of the storage rack. The second operation groove is opened at the center of the upper end of the second support frame. Two second linear modules are respectively installed on both sides of the front end of the storage rack. Two second clamping plates are respectively movably embedded on both sides of the second operation groove and are respectively connected to the driving ends of the two second linear modules.

[0015] In the specific implementation process, the lifting and traction structure includes: a top plate, two winches, two traction ropes and two traction blocks;

[0016] The top plate is fixedly installed at the tops of the four guide rods. Two winches are respectively installed on both sides of the upper end of the top plate. Two traction ropes respectively pass through both sides of the upper end of the top plate and are connected to the two winches. Two traction blocks are respectively installed at the lower ends of the two traction ropes and are respectively installed on both sides of the connecting frame.

[0017] In the specific implementation process, a lighting panel is provided on the lower wall surface of the top plate.

[0018] A usage method of a medical 3D optical imaging system includes the following steps: Step S1: First, support the device through the bottom plate, place the device in a designated imaging room, and connect it to a computer system. Subsequently, according to the detection and imaging requirements of the patient, replace the designated transmitting module and receiving module. The replacement process is as follows: Drive the first motor on one side of the moving block to work. Under the meshing action of the first gear and the internal gear ring, the moving block can move on the upper end of the annular slide rail until the moving block corresponds to the replacement structure. Subsequently, drive the two second motors in the mounting frame. Under the meshing action of the two second gears and the external gear ring, the mounting frame moves on the upper end of the arc slide rail until the mounting frame and the first clamping assembly rotate to the other side of the moving block and correspond to the replacement structure;

[0019] Step S2: First, the staff drives the third motor on the upper end of the moving plate. The third motor drives the mounting column to rotate a specified angle, so that the specified transmitting module and receiving module are located on one side of the first clamping assembly. Subsequently, the lifting and traction structure works to make the height of the first clamping assembly correspond to the specified transmitting module and receiving module. Then drive the electric push rod on one side of the upper end of the bottom plate to push the moving plate to move to one side in the two chutes until the specified transmitting module and receiving module are located in the first clamping assembly;

[0020] Step S3: The two first linear slides on one side of the mounting frame operate to drive the two first clamping plates to move outward in the first operation groove, increasing the distance between the two first clamping plates. At the same time, place the specified transmitting module or receiving module between the two first clamping plates through the replacement structure and make it fit against the side wall of the first support frame. Then, reverse-drive the two first linear slides to drive the two first clamping plates to move towards the center until the transmitting module or receiving module is clamped.

[0021] Step S4: The two second linear slides on one side of the storage rack operate to drive the two second clamping plates to move outward in the second operation groove, increasing the distance between the two second clamping plates. At the same time, place the specified transmitting module or receiving module between the two second clamping plates through the first clamping component and make it fit against the side wall of the second support frame. Then, reverse-drive the two second linear slides to drive the two second clamping plates to move towards the center until the transmitting module or receiving module is clamped.

[0022] Step S5: The medical staff connects the transmitting module and the receiving module to the computer system. Then, drive the four second motors to reset the angles of the two mounting frames, and drive the two first motors to operate again to align the transmitting module and the receiving module. Then, the medical staff guides the patient to stand on the upper end of the base plate. At the same time, drive the lifting and traction structure to operate, driving the connecting frame and the four moving sleeves to move uniformly on the upper ends of the four guide rods. At the same time, the first motors on one side of the two moving blocks rotate simultaneously, causing the two moving blocks to move synchronously on the upper end of the annular slide rail and always maintaining a corresponding state. Through the cooperation of the transmitting module and the receiving module, scan the patient, and the scanned information is processed and analyzed and converted into an image.

[0023] Step S6: When performing imaging detection on the patient, through the operation of the two winches on the upper end of the top plate, under the connection action of the two traction ropes and the two traction blocks, the connecting frame and the four moving sleeves can move on the upper ends of the guide rods, realizing the moving scan operation of the patient. And when replacing the transmitting module and the receiving module, the height of the connecting frame can be accurately adjusted.

[0024] In the specific implementation process, the transmitting module and the receiving module proposed in Step S1 can be changed according to requirements during use, and can be installed in a fixed manner with two transmitting modules or in a manner of cooperation between the transmitting module and the receiving module.

[0025] In the specific implementation process, the transmitting module and the receiving module used in step S1 are ultrasonic imaging high-frequency probes, and they are installed unidirectionally. The ultrasonic imaging high-frequency probe emits high-frequency (usually 1–20 MHz) sound waves. These sound waves penetrate the internal tissues. Different types of tissues have different characteristics for the propagation and reflection of sound waves. When ultrasonic waves enter the body, they interact with tissues of different densities and impedances in the body. Part of the sound waves are reflected back. The greater the density of the tissue, the stronger the reflection of the sound waves. For example, bones and gases reflect a large amount of sound waves, while liquids such as blood or water reflect less. The reflected sound waves are received by the receiving part in the probe. The piezoelectric crystals in the probe convert the reflected sound wave signals into electrical signals. The received electrical signals are sent to the computer system of the ultrasonic imaging device. After being processed and analyzed, they are converted into images.

[0026] In the specific implementation process, the transmitting module and the receiving module used in step S1 can be an X-ray source and a detector. The X-ray source emits an X-ray beam that penetrates the patient's body and passes through different tissue layers. Part of the rays are absorbed by the human body, and the remaining rays are received by the detector. Different tissues have different absorption capabilities for X-rays. For example, bones have a strong absorption of X-rays (high density), so they appear white in CT images; while soft tissues (such as muscles and fat) have a weak absorption of X-rays and appear gray or black. Therefore, by analyzing the absorption differences of different tissues for X-rays, a structural image of the internal tissues can be obtained. During the scanning process, the X-ray source and the detector rotate around the patient, generating X-ray perspective views (projection data) at different angles. These perspective views are two-dimensional. Through the computer system, they are combined and reconstructed into three-dimensional images through mathematical algorithms (such as filtered back projection or iterative reconstruction algorithms). These algorithms can integrate all the scanned projection data to obtain cross-sectional images of the internal structure of the human body. After being processed by the computer, the CT scanner generates a series of slice images. Each layer of image represents a small part of the patient's body. By adjusting the thickness and resolution of different image slices, doctors can obtain the required detailed information. In addition, the gray scale of CT images reflects the density of different tissues, which can help doctors distinguish different types of tissues, lesions and their properties. The reconstructed images can be displayed as slice images on the screen or reconstructed into three-dimensional images to help doctors better understand the spatial position of the lesions and their relationship with the surrounding tissues. Doctors can use these images for diagnosis, planning treatment plans or observing the changes of diseases.

[0027] A medical 3D optical imaging system and method made using the technical solution of the present invention. The imaging structure adopted in this case synchronously moves two moving blocks on an annular slide rail. The purpose of this design is to ensure the precise positioning of the imaging device and the coordination of the scanning path, facilitating a full-range scan of the patient during the scanning process. Moreover, the annular design of the slide rail helps the device to scan along a circular trajectory, ensuring a wider scanning coverage range. In cooperation with the lifting traction structure, it can be flexibly adjusted according to different body positions of the patient. After the scanning cooperation between the transmitting module and the receiving module, it is connected to a designated computer system. The computer system processes and analyzes the signal data. In this process, the received signals are converted into images to form specific imaging results for medical staff to carry out diagnosis and treatment planning. Through the combination of the arc-shaped slide rail and the mounting rack, the flipping operation of the first clamping component can be realized. And through the provided replacement structure, under different imaging requirements, the transmitting module and the receiving module can be conveniently replaced. This design enables a single device to support multiple different imaging technologies or scanning modes, avoiding the complexity brought by using different devices. Through this design, a single set of equipment can achieve multiple scanning imaging operations, avoiding the need for hospitals or research institutions to purchase multiple different functional devices. This not only effectively reduces the costs of hospitals or research institutions but also saves space and improves the usage efficiency of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

Both ends of the connecting frame 4 are respectively connected to the side walls of the four moving sleeves 3. The internal gear ring 5 is fixedly installed on one side of the connecting frame 4. A number of connecting blocks 6 are respectively installed on the upper wall surface of the internal gear ring 5. The annular slide rail 7 is fixedly installed on the upper ends of the number of connecting blocks 6. Two moving blocks 8 are respectively movably sleeved on both sides of the upper end of the annular slide rail 7.

Two first gears 10 are respectively installed on the driving ends of the two first motors 9 and are both meshed with the internal gear ring 5. Two arc-shaped slide rails 11 are respectively installed at the centers of the upper ends of the two moving blocks 8. Four external gear rings 12 are respectively installed on both sides of the upper ends of the two moving blocks 8. Two mounting frames 13 are movably sleeved on the upper ends of the two arc-shaped slide rails 11. Four second motors 14 are respectively embedded in the two sides of the two mounting frames 13.

Two first clamping assemblies are respectively installed on the outer sides of the two mounting frames 13. The transmitting module 16 and the receiving module 17 are respectively installed in the two first clamping assemblies.

[0040] When imaging a patient, first, the device is supported by the bottom plate 1, placed in a designated imaging room, and connected to a computer system. Subsequently, according to the patient's detection and imaging requirements, the first motor 9 on one side of the moving block 8 is driven to work. Under the meshing action of the first gear 10 and the internal gear ring 5, the moving block 8 can move on the upper end of the annular slide rail 7 until the moving block 8 corresponds to the replacement structure. Subsequently, by driving the two second motors 14 in the mounting frame 13, under the meshing action of the two second gears 15 and the external gear ring 12, the mounting frame 13 moves on the upper end of the arc-shaped slide rail 11 until the mounting frame 13 and the first clamping assembly rotate to the other side of the moving block 8 and correspond to the replacement structure. Through the cooperation of the replacement structure and the first clamping assembly, the designated transmitting module 16 and receiving module 17 can be replaced. After the replacement is completed, the medical staff connects the transmitting module 16 and the receiving module 17 to the computer system, then drives the four second motors 14 to reset the angles of the two mounting frames 13, and drives the two first motors 9 to work again to make the transmitting module 16 and the receiving module 17 correspond. Subsequently, the medical staff guides the patient to stand on the upper end of the bottom plate 1, and at the same time drives the lifting and traction structure to work, driving the connecting frame 4 and the four moving sleeves 3 to move uniformly on the upper ends of the four guide rods 2. At the same time, the first motors 9 on one side of the two moving blocks 8 rotate simultaneously, making the two moving blocks 8 move synchronously on the upper end of the annular slide rail 7 and always maintain a corresponding state. Through the cooperation of the transmitting module 16 and the receiving module 17, the patient is scanned, and the scanned information is processed and analyzed and converted into an image.

[0041] In the specific implementation process, both of the two first clamping components include: a first support frame 18, a first operation groove 19, two first linear sliders 20, and two first clamping plates 21;

[0042] The first support frame 18 is fixedly installed on one side of the mounting frame 13. The first operation groove 19 is opened at the center of the upper end of the first support frame 18. The two first linear modules are respectively installed on both sides of the front end of the mounting frame 13. The two first clamping plates 21 are respectively movably embedded on both sides inside the first operation groove 19 and are respectively connected to the driving ends of the two first linear modules.

[0043] When replacing and fixing the transmitting module 16 and the receiving module 17, first, the two first linear sliders 20 located on one side of the mounting frame 13 work, driving the two first clamping plates 21 to move outward in the first operation groove 19, increasing the distance between the two first clamping plates 21. At the same time, a specified transmitting module 16 or receiving module 17 is placed between the two first clamping plates 21 through the replacement structure and is attached to the side wall of the first support frame 18. Subsequently, the two first linear sliders 20 are driven in the reverse direction, driving the two first clamping plates 21 to move towards the center until the transmitting module 16 or the receiving module 17 is clamped.

[0044] In the specific implementation process, the replacement structure includes: two sliding grooves 22, a moving plate 23, a third motor 24, an electric push rod 25, a mounting column 26, a number of storage racks 27, and a number of second clamping components;

[0045] The two sliding grooves 22 are both installed on the upper end of the bottom plate 1. Both ends of the moving plate 23 are movably embedded in the two sliding grooves 22. The third motor 24 is fixedly installed on the upper end of the moving plate 23. One end of the electric push rod 25 is fixedly installed on one side of the upper end of the bottom plate 1, and the telescopic end is connected to one side of the moving plate 23. The mounting column 26 is fixedly installed on the driving end of the third motor 24. A number of storage racks 27 are respectively installed on the side wall of the mounting column 26. A number of second clamping components are respectively installed on one side of the number of storage racks 27.

[0046] When replacing and storing the transmitting module 16 and the receiving module 17, the staff first drives the third motor 24 at the upper end of the moving plate 23. The third motor 24 drives the mounting column 26 to rotate by a specified angle, so that the specified transmitting module 16 and receiving module 17 are located on one side of the first clamping assembly. Subsequently, the lifting and traction structure works to make the height of the first clamping assembly correspond to the specified transmitting module 16 and receiving module 17, and drives the electric push rod 25 on one side of the upper end of the bottom plate 1 to push the moving plate 23 to move to one side in the two sliding grooves 22 until the specified transmitting module 16 and receiving module 17 are located in the first clamping assembly, and the first clamping assembly fixes them. Subsequently, the specified second clamping assembly on one side of the storage rack 27 unfolds to release the transmitting module 16 or the receiving module 17, and by means of rotation and lateral movement, in cooperation with the lifting and traction structure, the storage and replacement of different transmitting modules 16 and receiving modules 17 can be realized.

[0047] In the specific implementation process, several second clamping assemblies each include: a second support frame 28, a second operation groove 29, two second linear slides 30 and two second clamping plates 31;

[0048] The second support frame 28 is fixedly installed on one side of the storage rack 27. The second operation groove 29 is opened at the center of the upper end of the second support frame 28. The two second linear modules are respectively installed on both sides of the front end of the storage rack 27. The two second clamping plates 31 are respectively movably embedded on both sides in the second operation groove 29 and are respectively connected to the driving ends of the two second linear modules.

[0049] When storing and fixing the transmitting module 16 and the receiving module 17, first, the two second linear slides 30 on one side of the storage rack 27 work to drive the two second clamping plates 31 to move outward in the second operation groove 29, so that the distance between the two second clamping plates 31 becomes larger. At the same time, the specified transmitting module 16 or receiving module 17 is placed between the two second clamping plates 31 through the first clamping assembly and is attached to the side wall of the second support frame 28. Subsequently, the two second linear slides 30 are driven in the reverse direction to drive the two second clamping plates 31 to move towards the center until the transmitting module 16 or receiving module 17 is clamped.

[0050] In the specific implementation process, the lifting and traction structure includes: a top plate 32, two winches 33, two traction ropes 34 and two traction blocks 35;

[0051] The top plate 32 is fixedly installed at the top of the four guide rods 2. The two winches 33 are respectively installed on both sides of the upper end of the top plate 32. The two traction ropes 34 respectively pass through both sides of the upper end of the top plate 32 and are connected to the two winches 33. The two traction blocks 35 are respectively installed at the lower ends of the two traction ropes 34 and are respectively installed on both sides of the connecting frame 4.

[0052] When imaging a patient, two winches 33 at the upper end of the top plate 32 work. Under the connection of two traction ropes 34 and two traction blocks 35, the connecting frame 4 and four moving sleeves 3 can move on the upper end of the guide rod 2, enabling the mobile scanning operation of the patient. And when replacing the transmitting module 16 and the receiving module 17, the height of the connecting frame 4 can be accurately adjusted.

[0053] In the specific implementation process, a lighting panel 36 is provided on the lower wall surface of the top plate 32.

[0054] A method for using a medical 3D optical imaging system includes the following steps: Step S1: First, support the device through the bottom plate 1, place the device in a designated imaging room, and connect it to a computer system. Then, according to the imaging requirements of the patient, replace the designated transmitting module 16 and receiving module 17. The replacement process is as follows: Drive the first motor 9 on one side of the moving block 8 to work. Under the meshing action of the first gear 10 and the internal gear ring 5, the moving block 8 can move on the upper end of the annular slide rail 7 until the moving block 8 corresponds to the replacement structure. Then, drive the two second motors 14 in the mounting frame 13. Under the meshing action of the two second gears 15 and the external gear ring 12, the mounting frame 13 moves on the upper end of the arc-shaped slide rail 11 until the mounting frame 13 and the first clamping assembly rotate to the other side of the moving block 8 and correspond to the replacement structure;

[0055] Step S2: First, the staff drives the third motor 24 on the upper end of the moving plate 23. The third motor 24 drives the mounting column 26 to rotate a specified angle, so that the specified transmitting module 16 and receiving module 17 are located on one side of the first clamping assembly. Then, through the operation of the lifting and traction structure, the height of the first clamping assembly corresponds to the specified transmitting module 16 and receiving module 17. Drive the electric push rod 25 on one side of the upper end of the bottom plate 1 to push the moving plate 23 to move to one side in the two sliding grooves 22 until the specified transmitting module 16 and receiving module 17 are located within the first clamping assembly;

[0056] Step S3: Two first linear slides 20 on one side of the mounting frame 13 work, driving two first clamping plates 21 to move outward in the first operation groove 19, increasing the distance between the two first clamping plates 21. At the same time, place the specified transmitting module 16 or receiving module 17 between the two first clamping plates 21 through the replacement structure and make it fit against the side wall of the first support frame 18. Then, reverse-drive the two first linear slides 20 to drive the two first clamping plates 21 to move towards the center until the transmitting module 16 or receiving module 17 is clamped;

[0057] Step S4: The two second linear sliders 30 located on one side of the storage rack 27 operate to drive the two second clamping plates 31 to move outward in the second operation groove 29, increasing the distance between the two second clamping plates 31. At the same time, the specified transmitting module 16 or receiving module 17 is placed between the two second clamping plates 31 through the first clamping assembly and abuts against the side wall of the second support frame 28. Subsequently, the two second linear sliders 30 are driven in reverse to drive the two second clamping plates 31 to move towards the center until the transmitting module 16 or receiving module 17 is clamped.

[0058] Step S5: The medical staff connects the transmitting module 16 and the receiving module 17 to the computer system. Subsequently, the four second motors 14 are driven to reset the angles of the two mounting brackets 13, and the two first motors 9 are driven to operate again to align the transmitting module 16 and the receiving module 17. Then, the medical staff guides the patient to stand on the upper end of the bottom plate 1. At the same time, the lifting and traction structure is driven to work, driving the connecting frame 4 and the four moving sleeves 3 to move uniformly on the upper ends of the four guide rods 2. At the same time, the first motors 9 located on one side of the two moving blocks 8 rotate simultaneously, causing the two moving blocks 8 to move synchronously on the upper end of the annular slide rail 7 and always maintain a corresponding state. Through the cooperation of the transmitting module 16 and the receiving module 17, the patient is scanned, and the scanned information is processed and analyzed to be converted into an image.

[0059] Step S6: When performing imaging detection on the patient, the two winches 33 on the upper end of the top plate 32 operate. Under the connection action of the two traction ropes 34 and the two traction blocks 35, the connecting frame 4 and the four moving sleeves 3 can be moved on the upper ends of the guide rods 2, realizing the moving scan operation of the patient. Moreover, when replacing the transmitting module 16 and the receiving module 17, the height of the connecting frame 4 can be accurately adjusted.

[0060] In the specific implementation process, the transmitting module 16 and the receiving module 17 proposed in Step S1 can be changed according to requirements during use, and can be installed in a fixed manner with two transmitting modules 16 or in a manner of cooperation between the transmitting module 16 and the receiving module 17.

[0061] In the specific implementation process, the transmitting module 16 and the receiving module 17 used in step S1 are high-frequency ultrasonic imaging probes, and they are installed unidirectionally. The high-frequency ultrasonic imaging probe emits high-frequency (usually 1–20 MHz) sound waves. These sound waves penetrate the internal tissues of the body. Different types of tissues have different characteristics for the propagation and reflection of sound waves. When ultrasonic waves enter the body, they interact with tissues of different densities and impedances in the body. Part of the sound waves are reflected back. The greater the density of the tissue, the stronger the reflection of the sound waves. For example, bones and gases reflect a large amount of sound waves, while liquids such as blood or water reflect less. The reflected sound waves are received by the receiving part in the probe. The piezoelectric crystals in the probe convert the reflected sound wave signals into electrical signals. The received electrical signals are sent to the computer system of the ultrasonic imaging device. After being processed and analyzed, they are converted into images.

[0062] In the specific implementation process, the transmitting module 16 and the receiving module 17 used in step S1 can be an X-ray source and a detector. The X-ray source emits an X-ray beam that penetrates the patient's body and passes through different tissue layers. Part of the rays are absorbed by the human body, and the remaining rays are received by the detector. Different tissues have different absorption capabilities for X-rays. For example, bones have a strong absorption of X-rays (high density), so they appear white on a CT image; while soft tissues (such as muscles and fat) have a weak absorption of X-rays and appear gray or black. Therefore, by analyzing the absorption differences of different tissues for X-rays, a structural image of the internal tissues can be obtained. During the scanning process, the X-ray source and the detector rotate around the patient to generate X-ray perspective views (projection data) at different angles. These perspective views are two-dimensional. Through the computer system, they are combined and reconstructed into a three-dimensional image through mathematical algorithms (such as filtered back projection or iterative reconstruction algorithms). These algorithms can integrate all the scanned projection data to obtain a cross-sectional image of the internal structure of the human body. After being processed by the computer, the CT scanner will generate a series of slice images. Each layer of the image represents a small part of the patient's body. By adjusting the thickness and resolution of different image slices, doctors can obtain the required detailed information. In addition, the gray scale of the CT image reflects the density of different tissues, which can help doctors distinguish different types of tissues, lesions, and their properties. The reconstructed image can be displayed as a slice image on the screen or reconstructed into a three-dimensional image to help doctors better understand the spatial position of the lesion and its relationship with the surrounding tissues. Doctors can use these images for diagnosis, planning treatment plans, or observing the changes of diseases.

The high-frequency ultrasonic imaging probe transmits high-frequency (usually 1-20MHz) sound waves. These sound waves penetrate tissues in the body. Different types of tissues have different characteristics for the propagation and reflection of sound waves. When ultrasound enters the body, it interacts with tissues of different densities and impedances in the body. Part of the sound waves are reflected back. The greater the density of the tissue, the stronger the reflection of the sound waves. For example, bones and gases reflect a large amount of sound waves, while liquids such as blood or water reflect less. The reflected sound waves are received by the receiving part in the probe. The piezoelectric crystal in the probe converts the reflected sound wave signal into an electrical signal. The received electrical signal is sent to the computer system of the ultrasonic imaging device, and is processed and analyzed to be converted into an image.

10. The method for using a medical 3D optical imaging system according to claim 7, characterized in that: The transmitting module and receiving module used in step S1 can be an X-ray source and a detector. The X-ray source emits an X-ray beam, which penetrates the patient's body and passes through different tissue layers. Part of the rays are absorbed by the human body, and the remaining rays are received by the detector. Different tissues have different absorption capacities for X-rays. For example, bones absorb X-rays more strongly (high density), so they appear white on the CT image; while soft tissues (such as muscles and fat) absorb X-rays less strongly and appear gray or black. Therefore, by analyzing the differences in X-ray absorption by different tissues, a structural image of the internal tissue can be obtained. During the scanning process, the X-ray source and the detector rotate around the patient to generate X-ray perspective images (projection data) at different angles. These perspective images are two-dimensional and are combined by a computer system and mathematically processed. The CT scanner reconstructs the image into a three-dimensional image using algorithms (such as filtered back projection or iterative reconstruction algorithms). These algorithms can integrate all the projection data of the scan to obtain cross-sectional images of the internal structure of the human body. After computer processing, the CT scanner will generate a series of slice images, each layer of which represents a small part of the patient's body. By adjusting the thickness and resolution of different image slices, doctors can obtain the detailed information they need. In addition, the grayscale of the CT image reflects the density of different tissues, which can help doctors distinguish different types of tissues, lesions and their properties. The reconstructed image can be displayed on the screen as a slice image or reconstructed into a three-dimensional image to help doctors better understand the spatial location of the lesion and its relationship with the surrounding tissues. Doctors can use these images to make diagnoses, plan treatment plans or observe changes in the disease.
